android-h264-stream-demo

What it does

This is an example project to show how to streaming from android camera to VLC or gstreamer.

This demo project use MediaCodec API to encode H.264 data and simply wrap with UDP packet then send these packets to VLC or gstreamer.

How does it work

The working flow as below

camera preview data(YV12) -> YUV420sp -> MediaCodec -> H.264 data -> UDP 

Media Server

By using VLC and gstreamer, we can ensure that the H.264 video streaming is working fine. You can use the following command to start a media server.

VLC

vlc -vvv udp://@:<port>

gstreamer

gst-launch udpsrc port=<port> ! video/x-h264,width=<w>,height=<h>,framerate=<framerate>/1 ! ffdec_h264 ! autovideosink

Requirement

• Minimal API requirement: 16

Notes

• In some network environment, UDP packet may be cut by MTU limitation

Future works

• Support H.264 over RTP (RFC3984)
• Support NV21 and YUV420p image format
