NetGear's SSH Tunneling Mode
+
+ +## Overview + +!!! new "New in v0.2.2" + This document was added in `v0.2.2`. + + +SSH Tunneling Mode allows you to connect NetGear client and server via secure SSH connection over the untrusted network and access its intranet services across firewalls. This mode works with pyzmq's [`zmq.ssh`](https://github.com/zeromq/pyzmq/tree/main/zmq/ssh) module for tunneling ZeroMQ connections over ssh. + +This mode implements [SSH Remote Port Forwarding](https://www.ssh.com/academy/ssh/tunneling/example) which enables accessing Host(client) machine outside the network by exposing port to the public Internet. Thereby, once you have established the tunnel, connections to local machine will actually be connections to remote machine as seen from the server. + +??? danger "Beware ☠️" + Cybercriminals or malware could exploit SSH tunnels to hide their unauthorized communications, or to exfiltrate stolen data from the network. More information can be found [here ➶](https://www.ssh.com/academy/ssh/tunneling) + +All patterns are valid for this mode and it can be easily activated in NetGear API at server end through `ssh_tunnel_mode` string attribute of its [`options`](../../params/#options) dictionary parameter during initialization. + +!!! warning "Important" + * ==SSH tunneling can only be enabled on Server-end to establish remote SSH connection with Client.== + * SSH tunneling Mode is **NOT** compatible with [Multi-Servers](../../advanced/multi_server) and [Multi-Clients](../../advanced/multi_client) Exclusive Modes yet. + +!!! tip "Useful Tips" + * It is advise to use `pattern=2` to overcome random disconnection due to delays in network. + * SSH tunneling Mode is fully supports [Bidirectional Mode](../../advanced/multi_server), [Secure Mode](../../advanced/secure_mode/) and [JPEG-Frame Compression](../../advanced/compression/). + * It is advised to enable logging (`logging = True`) on the first run, to easily identify any runtime errors. + +  + + +## Requirements + +SSH Tunnel Mode requires [`pexpect`](http://www.noah.org/wiki/pexpect) or [`paramiko`](http://www.lag.net/paramiko/) as an additional dependency which is not part of standard VidGear package. It can be easily installed via pypi as follows: + + +=== "Pramiko" + + !!! success "`paramiko` is compatible with all platforms." + + !!! info "`paramiko` support is automatically enabled in ZeroMQ if installed." + + ```sh + # install paramiko + pip install paramiko + ``` + +=== "Pexpect" + + !!! fail "`pexpect` is NOT compatible with Windows Machines." + + ```sh + # install pexpect + pip install pexpect + ``` + +  + +## Supported Attributes + + +!!! warning "All these attributes will work on Server end only whereas Client end will simply discard them." + +For implementing SSH Tunneling Mode, NetGear API currently provide following attribute for its [`options`](../../params/#options) dictionary parameter: + +* **`ssh_tunnel_mode`** (_string_) : This attribute activates SSH Tunneling Mode and sets the fully specified `"@:"` SSH URL for tunneling at Server end. Its usage is as follows: + + !!! fail "On Server end, NetGear automatically validates if the `port` is open at specified SSH URL or not, and if it fails _(i.e. port is closed)_, NetGear will throw `AssertionError`!" + + === "With Default Port" + !!! info "The `port` value in SSH URL is the forwarded port on host(client) machine. Its default value is `22`_(meaning default SSH port is forwarded)_." + + ```python + # activates SSH Tunneling and assign SSH URL + options = {"ssh_tunnel_mode":"userid@52.194.1.73"} + # only connections from the public IP address 52.194.1.73 on default port 22 are allowed + ``` + + === "With Custom Port" + !!! quote "You can also define your custom forwarded port instead." + + ```python + # activates SSH Tunneling and assign SSH URL + options = {"ssh_tunnel_mode":"userid@52.194.1.73:8080"} + # only connections from the public IP address 52.194.1.73 on custom port 8080 are allowed + ``` + +* **`ssh_tunnel_pwd`** (_string_): This attribute sets the password required to authorize Host for SSH Connection at Server end.

+## Overview In Multi-Clients Mode, NetGear robustly handles Multiple Clients at once thereby able to broadcast frames and data across multiple Clients/Consumers in the network at same time. This mode works almost contrary to [Multi-Servers Mode](../multi_server/) but here data transfer works unidirectionally with pattern `1` _(i.e. Request/Reply `zmq.REQ/zmq.REP`)_ only.

[`read()`](https://docs.opencv.org/master/d8/dfe/classcv_1_1VideoCapture.html#a473055e77dd7faa4d26d686226b292c1) is a [**Blocking I/O**](https://luminousmen.com/post/asynchronous-programming-blocking-and-non-blocking) function for reading and decoding the next video-frame, and consumes much of the I/O bound memory depending upon our video source properties & system hardware. This essentially means, the corresponding thread that reads data from it, is continuously blocked from retrieving the next frame. As a result, our python program appears slow and sluggish even without any type of computationally expensive image processing operations. This problem is far more severe on low memory SBCs like Raspberry Pis. +In Threaded-Queue-Mode, VidGear creates several [**Python Threads**](https://docs.python.org/3/library/threading.html) within one process to offload the frame-decoding task to a different thread. Thereby, VidGear is able to execute different Video I/O-bounded operations at the same time by overlapping there waiting times. Moreover, threads are managed by operating system itself and is capable of distributing them between available CPU cores efficiently. In this way, Threaded-Queue-Mode keeps on processing frames faster in the [background](https://en.wikipedia.org/wiki/Daemon_(computing)) without waiting for blocked I/O operations and not affected by sluggishness in our main python thread. -Thereby in Threaded-Queue-Mode, to tackle this problem, VidGear creates several [**Python Threads**](https://docs.python.org/3/library/threading.html) within one process to offload the frame-decoding task to a different thread.

Monitors Fix-Sized Queues +### B. Utilizes Fixed-Size Queues > Although Multi-threading is fast, easy, and efficient, it can lead to some serious undesired effects like _frame-skipping, Global Interpreter Locks, race conditions, etc._ This is because there is no isolation whatsoever in python threads, if there is any crash, it may cause not only one particular thread to crash but the whole process to crash. That's not all, the biggest difficulty is that memory of the process where threads work is shared by different threads and that may result in frequent process crashes due to unwanted race conditions. -These problems are avoided in Threaded-Queue-Mode by utilizing **Thread-Safe, Memory-Efficient, and Fixed-Sized [`Queue`](https://docs.python.org/3/library/queue.html#module-queue)** _(with approximately same O(1) performance in both directions)_ that singly supervises the synchronized access to frame-decoding thread and basically isolates it from other threads, and thus prevents [**Global Interpreter Lock**](https://realpython.com/python-gil/). With queues, VidGear always maintains a fixed-length frames buffer in the memory and blocks the thread temporarily if the queue is full to avoid possible frame drops or otherwise pops out the frames synchronously without any obstructions. +These problems are avoided in Threaded-Queue-Mode by utilizing **Thread-Safe, Memory-Efficient, and Fixed-Size [`Queues`](https://docs.python.org/3/library/queue.html#module-queue)** _(with approximately same O(1) performance in both directions)_, that single handedly monitors the synchronized access to frame-decoding thread and basically isolates it from other threads and thus prevents [**Global Interpreter Lock**](https://realpython.com/python-gil/). + +### C.

This significantly accelerates frame processing rate (and therefore our overall video processing pipeline) comes from dramatically reducing latency — since we don’t have to wait for the `read()` method to finish reading and decoding a frame; instead, there is always a pre-decoded frame ready for us to process.   diff --git a/docs/changelog.md b/docs/changelog.md index 16f28a802..50351f675 100644 --- a/docs/changelog.md +++ b/docs/changelog.md @@ -76,14 +76,14 @@ limitations under the License. * [ ] Updated mkdocs.yml. - [x] Helper: * [ ] Implemented new `delete_file_safe` to safely delete files at given path. - * [ ] Renamed `delete_safe` to `delete_ext_safe`. + * [ ] Replaced `os.remove` calls with `delete_file_safe`. - [x] CI: * [ ] Updated VidGear Docs Deployer Workflow * [ ] Updated test - [x] Updated issue templates and labels. ??? danger "Breaking Updates/Changes" - - [ ] Replaced `os.remove` calls with `delete_file_safe`. + - [ ] Renamed `delete_safe` to `delete_ext_safe`. ??? bug "Bug-fixes" diff --git a/docs/index.md b/docs/index.md index 64d46d2c3..0c8908a2a 100644 --- a/docs/index.md +++ b/docs/index.md @@ -30,7 +30,7 @@ limitations under the License. > VidGear is a High-Performance **Video-Processing** Framework for building complex real-time media applications in python :fire: -VidGear provides an easy-to-use, highly extensible, **Multi-Threaded + Asyncio Framework** on top of many state-of-the-art specialized libraries like *[OpenCV][opencv], [FFmpeg][ffmpeg], [ZeroMQ][zmq], [picamera][picamera], [starlette][starlette], [streamlink][streamlink], [pafy][pafy], [pyscreenshot][pyscreenshot], [aiortc][aiortc] and [python-mss][mss]* at its backend, and enable us to flexibly exploit their internal parameters and methods, while silently delivering robust error-handling and real-time performance ⚡️. +VidGear provides an easy-to-use, highly extensible, **[Multi-Threaded](../bonus/TQM/#threaded-queue-mode) + Asyncio Framework** on top of many state-of-the-art specialized libraries like *[OpenCV][opencv], [FFmpeg][ffmpeg], [ZeroMQ][zmq], [picamera][picamera], [starlette][starlette], [streamlink][streamlink], [pafy][pafy], [pyscreenshot][pyscreenshot], [aiortc][aiortc] and [python-mss][mss]* at its backend, and enable us to flexibly exploit their internal parameters and methods, while silently delivering robust error-handling and real-time performance ⚡️. > _"Write Less and Accomplish More"_ — VidGear's Motto diff --git a/docs/installation/pip_install.md b/docs/installation/pip_install.md index 2155bfcd5..5928c63bf 100644 --- a/docs/installation/pip_install.md +++ b/docs/installation/pip_install.md @@ -143,10 +143,10 @@ Installation is as simple as: **Or you can also download its wheel (`.whl`) package from our repository's [releases](https://github.com/abhiTronix/vidgear/releases) section, and thereby can be installed as follows:** ```sh - pip install vidgear-0.2.1-py3-none-any.whl + pip install vidgear-0.2.2-py3-none-any.whl # or with asyncio support - pip install vidgear-0.2.1-py3-none-any.whl[asyncio] + pip install vidgear-0.2.2-py3-none-any.whl[asyncio] ```   diff --git a/docs/switch_from_cv.md b/docs/switch_from_cv.md index f9781f3f0..bce2bc7c4 100644 --- a/docs/switch_from_cv.md +++ b/docs/switch_from_cv.md @@ -42,10 +42,10 @@ Switching OpenCV with VidGear APIs is usually a fairly painless process, and wil VidGear employs OpenCV at its backend and enhances its existing capabilities even further by introducing many new state-of-the-art features on top of it like: -- [x] Multi-Threaded Performance. +- [x] [Accerlated Multi-Threaded](../bonus/TQM/#c-accelerates-frame-processing) Performance. - [x] Real-time Stabilization. - [x] Inherit support for multiple sources. -- [x] Screen-casting, live network-streaming, plus [way much more ➶](../gears) +- [x] Screen-casting, Live network-streaming, [plus way much more ➶](../gears) Vidgear offers all this while maintaining the same standard OpenCV-Python _(Python API for OpenCV)_ coding syntax for all of its APIs, thereby making it even easier to implement Complex OpenCV applications in fewer lines of python code.

StreamGear API's generalized workflow
+
+ + +## Overview + +> StreamGear automates transcoding workflow for generating _Ultra-Low Latency, High-Quality, Dynamic & Adaptive Streaming Formats (such as MPEG-DASH)_ in just few lines of python code. + +StreamGear provides a standalone, highly extensible, and flexible wrapper around [**FFmpeg**](https://ffmpeg.org/) multimedia framework for generating chunked-encoded media segments of the content. + +SteamGear easily transcodes source videos/audio files & real-time video-frames and breaks them into a sequence of multiple smaller chunks/segments of fixed length. These segments make it possible to stream videos at different quality levels _(different bitrates or spatial resolutions)_ and can be switched in the middle of a video from one quality level to another – if bandwidth permits – on a per-segment basis. A user can serve these segments on a web server that makes it easier to download them through HTTP standard-compliant GET requests. + +SteamGear also creates a Manifest file _(such as MPD in-case of DASH)_ besides segments that describe these segment information _(timing, URL, media characteristics like video resolution and bit rates)_ and is provided to the client before the streaming session. + +SteamGear currently only supports [**MPEG-DASH**](https://www.encoding.com/mpeg-dash/) _(Dynamic Adaptive Streaming over HTTP, ISO/IEC 23009-1)_ , but other adaptive streaming technologies such as Apple HLS, Microsoft Smooth Streaming, will be added soon. Also, Multiple DRM support is yet to be implemented. + +  + +!!! danger "Important" + + * StreamGear **MUST** requires FFmpeg executables for its core operations. Follow these dedicated [Platform specific Installation Instructions ➶](../ffmpeg_install/) for its installation. + + * :warning: StreamGear API will throw **RuntimeError**, if it fails to detect valid FFmpeg executables on your system. + + * It is advised to enable logging _([`logging=True`](../params/#logging))_ on the first run for easily identifying any runtime errors. + +  + +## Mode of Operations + +StreamGear primarily operates in following independent modes for transcoding: + +- [**Single-Source Mode**](../ssm/overview): In this mode, StreamGear transcodes entire video/audio file _(as opposed to frames by frame)_ into a sequence of multiple smaller chunks/segments for streaming. This mode works exceptionally well, when you're transcoding lossless long-duration videos(with audio) for streaming and required no extra efforts or interruptions. But on the downside, the provided source cannot be changed or manipulated before sending onto FFmpeg Pipeline for processing. + +- [**Real-time Frames Mode**](../rtfm/overview): In this mode, StreamGear directly transcodes video-frames _(as opposed to a entire file)_, into a sequence of multiple smaller chunks/segments for streaming. In this mode, StreamGear supports real-time [`numpy.ndarray`](https://numpy.org/doc/1.18/reference/generated/numpy.ndarray.html#numpy-ndarray) frames, and process them over FFmpeg pipeline.

Real-time Frames Mode generalized workflow
-
- -When no valid input is received on [`-video_source`](../params/#a-exclusive-parameters) attribute of [`stream_params`](../params/#supported-parameters) dictionary parameter, StreamGear API activates this mode where it directly transcodes real-time [`numpy.ndarray`](https://numpy.org/doc/1.18/reference/generated/numpy.ndarray.html#numpy-ndarray) video-frames _(as opposed to a entire file)_ into a sequence of multiple smaller chunks/segments for streaming. - -In this mode, StreamGear **DOES NOT** automatically maps video-source audio to generated streams. You need to manually assign separate audio-source through [`-audio`](../params/#a-exclusive-parameters) attribute of `stream_params` dictionary parameter. - -This mode provide [`stream()`](../../../bonus/reference/streamgear/#vidgear.gears.streamgear.StreamGear.stream) function for directly trancoding video-frames into streamable chunks over the FFmpeg pipeline. - - -!!! warning - - * Using [`transcode_source()`](../../../bonus/reference/streamgear/#vidgear.gears.streamgear.StreamGear.transcode_source) function instead of [`stream()`](../../../bonus/reference/streamgear/#vidgear.gears.streamgear.StreamGear.stream) in Real-time Frames Mode will instantly result in **`RuntimeError`**! - - * **NEVER** assign anything to [`-video_source`](../params/#a-exclusive-parameters) attribute of [`stream_params`](../params/#supported-parameters) dictionary parameter, otherwise [Single-Source Mode](#a-single-source-mode) may get activated, and as a result, using [`stream()`](../../../bonus/reference/streamgear/#vidgear.gears.streamgear.StreamGear.stream) function will throw **`RuntimeError`**! - - * You **MUST** use [`-input_framerate`](../params/#a-exclusive-parameters) attribute to set exact value of input framerate when using external audio in this mode, otherwise audio delay will occur in output streams. - - * Input framerate defaults to `25.0` fps if [`-input_framerate`](../params/#a-exclusive-parameters) attribute value not defined. - - - -  - -### B.1 Bare-Minimum Usage - -Following is the bare-minimum code you need to get started with StreamGear API in Real-time Frames Mode: - -!!! note "We are using [CamGear](../../camgear/overview/) in this Bare-Minimum example, but any [VideoCapture Gear](../../#a-videocapture-gears) will work in the similar manner." - -```python -# import required libraries -from vidgear.gears import CamGear -from vidgear.gears import StreamGear -import cv2 - -# open any valid video stream(for e.g `foo1.mp4` file) -stream = CamGear(source='foo1.mp4').start() - -# describe a suitable manifest-file location/name -streamer = StreamGear(output="dash_out.mpd") - -# loop over -while True: - - # read frames from stream - frame = stream.read() - - # check for frame if Nonetype - if frame is None: - break - - - # {do something with the frame here} - - - # send frame to streamer - streamer.stream(frame) - - # Show output window - cv2.imshow("Output Frame", frame) - - # check for 'q' key if pressed - key = cv2.waitKey(1) & 0xFF - if key == ord("q"): - break - -# close output window -cv2.destroyAllWindows() - -# safely close video stream -stream.stop() - -# safely close streamer -streamer.terminate() -``` - -!!! success "After running these bare-minimum commands, StreamGear will produce a Manifest file _(`dash.mpd`)_ with steamable chunks that contains information about a Primary Stream of same resolution and framerate[^1] as input _(without any audio)_." - - -  - -### B.2 Bare-Minimum Usage with Live-Streaming - -If you want to **Livestream in Real-time Frames Mode** _(chunks will contain information for few new frames only)_, which is excellent for building Low Latency solutions such as Live Camera Streaming, then you can use exclusive [`-livestream`](../params/#a-exclusive-parameters) attribute of `stream_params` dictionary parameter as follows: - -!!! tip "Use `-window_size` & `-extra_window_size` FFmpeg parameters for controlling number of frames to be kept in Chunks. Less these value, less will be latency." - -!!! warning "All Chunks will be overwritten in this mode after every few Chunks _(equal to the sum of `-window_size` & `-extra_window_size` values)_, Hence Newer Chunks and Manifest contains NO information of any older video-frames." - -!!! note "In this mode, StreamGear **DOES NOT** automatically maps video-source audio to generated streams.

StreamGear API's generalized workflow
-
- - -## Overview - -> StreamGear automates transcoding workflow for generating _Ultra-Low Latency, High-Quality, Dynamic & Adaptive Streaming Formats (such as MPEG-DASH)_ in just few lines of python code. - -StreamGear provides a standalone, highly extensible, and flexible wrapper around [**FFmpeg**](https://ffmpeg.org/) multimedia framework for generating chunked-encoded media segments of the content. - -SteamGear easily transcodes source videos/audio files & real-time video-frames and breaks them into a sequence of multiple smaller chunks/segments of fixed length. These segments make it possible to stream videos at different quality levels _(different bitrates or spatial resolutions)_ and can be switched in the middle of a video from one quality level to another – if bandwidth permits – on a per-segment basis. A user can serve these segments on a web server that makes it easier to download them through HTTP standard-compliant GET requests. - -SteamGear also creates a Manifest file _(such as MPD in-case of DASH)_ besides segments that describe these segment information _(timing, URL, media characteristics like video resolution and bit rates)_ and is provided to the client before the streaming session. - -SteamGear currently only supports [**MPEG-DASH**](https://www.encoding.com/mpeg-dash/) _(Dynamic Adaptive Streaming over HTTP, ISO/IEC 23009-1)_ , but other adaptive streaming technologies such as Apple HLS, Microsoft Smooth Streaming, will be added soon. Also, Multiple DRM support is yet to be implemented. - -  - -!!! danger "Important" - - * StreamGear **MUST** requires FFmpeg executables for its core operations. Follow these dedicated [Platform specific Installation Instructions ➶](../ffmpeg_install/) for its installation. - - * :warning: StreamGear API will throw **RuntimeError**, if it fails to detect valid FFmpeg executables on your system. - - * It is advised to enable logging _([`logging=True`](../params/#logging))_ on the first run for easily identifying any runtime errors. - -  - -## Mode of Operations - -StreamGear primarily operates in following independent modes for transcoding: - -- [**Single-Source Mode**](../ssm/overview): In this mode, StreamGear transcodes entire video/audio file _(as opposed to frames by frame)_ into a sequence of multiple smaller chunks/segments for streaming. This mode works exceptionally well, when you're transcoding lossless long-duration videos(with audio) for streaming and required no extra efforts or interruptions. But on the downside, the provided source cannot be changed or manipulated before sending onto FFmpeg Pipeline for processing. - -- [**Real-time Frames Mode**](../rtfm/overview): In this mode, StreamGear directly transcodes video-frames _(as opposed to a entire file)_, into a sequence of multiple smaller chunks/segments for streaming. In this mode, StreamGear supports real-time [`numpy.ndarray`](https://numpy.org/doc/1.18/reference/generated/numpy.ndarray.html#numpy-ndarray) frames, and process them over FFmpeg pipeline. But on the downside, audio has to added manually _(as separate source)_ for streams. - -  - -## Importing - -You can import StreamGear API in your program as follows: - -```python -from vidgear.gears import StreamGear -``` - -  - - -## Watch Demo - -Watch StreamGear transcoded MPEG-DASH Stream: - -

But If a dependency is present, but older than specified, an error is raised if specified. - ✨ Implemented behavior that if a dependency is present, but older than `min_version` specified, an error is raised always. - ✨ Implemented `custom_message` to display custom message on error instead of default one. - 🔥 Removed redundant `logger_handler`, `mkdir_safe`, `retrieve_best_interpolation`, `capPropId` helper functions from asyncio package. - 🎨 Relatively imported helper functions from non-asyncio package. - ⚡️ Implemented separate `import_core_dependency` function to import and check for specified core dependency. `ImportError` will be raised immediately if core dependency not found. - Setup.py: - 🔥 Removed version check on certain dependencies. - ⏪️ Re-added `aiortc` to auto-install latest version. - Docs: - 📝 Updated URL and context for CamGear example. - ✏️ Fixed typos in usage examples. - 💡 Updated code comments. - 📝 Other Minor updates. - CI: 👷 Imported correct `logger_handler` for asyncio tests. - Codecov: ☂️ Added `__init__.py` to ignore. --- codecov.yml | 1 + docs/gears/camgear/usage.md | 6 +- .../netgear/advanced/bidirectional_mode.md | 6 +- docs/gears/netgear/advanced/compression.md | 4 +- docs/gears/netgear/advanced/multi_client.md | 12 +- docs/gears/netgear/advanced/multi_server.md | 15 +- docs/gears/netgear/advanced/secure_mode.md | 6 +- docs/gears/netgear/advanced/ssh_tunnel.md | 6 +- docs/gears/screengear/usage.md | 4 +- docs/gears/webgear/advanced.md | 8 +- docs/gears/webgear_rtc/advanced.md | 2 +- setup.py | 12 +- vidgear/gears/__init__.py | 164 +++++++++++++++++- vidgear/gears/asyncio/__init__.py | 1 + vidgear/gears/asyncio/__main__.py | 2 +- vidgear/gears/asyncio/helper.py | 109 +----------- vidgear/gears/asyncio/netgear_async.py | 34 ++-- vidgear/gears/asyncio/webgear.py | 33 ++-- vidgear/gears/asyncio/webgear_rtc.py | 54 +++--- vidgear/gears/camgear.py | 14 +- vidgear/gears/helper.py | 150 ++++++++++++++-- vidgear/gears/netgear.py | 56 +++--- vidgear/gears/pigear.py | 33 ++-- vidgear/gears/screengear.py | 20 ++- vidgear/gears/stabilizer.py | 4 +- vidgear/gears/streamgear.py | 4 +- vidgear/gears/videogear.py | 3 + vidgear/gears/writegear.py | 10 +- .../asyncio_tests/test_helper.py | 2 +- .../asyncio_tests/test_netgear_async.py | 2 +- .../asyncio_tests/test_webgear.py | 2 +- .../asyncio_tests/test_webgear_rtc.py | 2 +- 32 files changed, 494 insertions(+), 287 deletions(-) diff --git a/codecov.yml b/codecov.yml index 544e750c8..7cef6987d 100644 --- a/codecov.yml +++ b/codecov.yml @@ -30,5 +30,6 @@ ignore: - "vidgear/tests" - "docs" - "scripts" + - "vidgear/gears/__init__.py" #trivial - "vidgear/gears/asyncio/__main__.py" #trivial - "setup.py" \ No newline at end of file diff --git a/docs/gears/camgear/usage.md b/docs/gears/camgear/usage.md index d2b377c13..0583fe944 100644 --- a/docs/gears/camgear/usage.md +++ b/docs/gears/camgear/usage.md @@ -66,7 +66,7 @@ stream.stop() ## Using Camgear with Streaming Websites -CamGear API provides direct support for piping video streams from various popular streaming services like [Twitch](https://www.twitch.tv/), [Livestream](https://livestream.com/), [Dailymotion](https://www.dailymotion.com/live), and [many more ➶](https://streamlink.github.io/plugin_matrix.html#plugins).
