imx6q rstp stream and h264 decoding

ddejean — Fri, 20 Mar 2015 15:38:22 GMT

Hi everyone,

Our team is currently trying to play a RTSP stream with H264 encoded video with a Wandboard Quad running Android and we are facing some issues.

For information our wandboard quad is running the Freescale Kitkat 4.4 android port.

We first tried to diffuse with RTSP a 1080p movie (https://peach.blender.org/trailer-page/) using gstreamer (gst-rtsp-server-1.0/examples/test-mp4 ) on a computer and read it using the mediaframework on the wandboard and it worked perfectly.

Now we're trying to read a stream coming from a VLC rtsp server which casts the computer screen:

cvlc screen:// --screen-fps=30.000000 --screen-width=1920 --screen-height=1080 --live-caching=300 '--sout=#transcode{vcodec=h264,venc=x264{profile=high,preset=ultrafast,tune=zerolatency},fps=30,acodec=none}:rtp{sdp=rtsp://:8554/display}' --sout-keep

And we read it from a small android app which uses the media framework:

mediaPlayer = new MediaPlayer();

try {

mediaPlayer.setDataSource(context, Uri.parse("rtsp://192.168.2.26:8554/display"));

mediaPlayer.setOnPreparedListener(this);

mediaPlayer.prepare();

if (surface != null) {

mediaPlayer.setSurface(surface);

}

mediaPlayer.start();

} catch (IOException e) {

e.printStackTrace();

}

And the display stays black, there's no picture. Activating traces in the media framework we get the attached traces (see below or trace-1080p.txt attached file).

Then if we force VLC to scale to 720 it seems to work a bit better: ie we get an image, we don't have so much error traces but the display freezes after some time.

Does someone have any idea why we're not able to play this ? Any input/help would be welcome
