Android4.4.2 UDP stream on i.MX6Q

[lqll]

Hi,sir:

     According to <i_MX_Android_Extended_Codec_Release_Notes>,I  update android_kk4.4.2_1.0.0-ga_omxplayer_source.tar.gz ,then I can play udp stream on i.MX6Q,but I found that only some video can play well,others full of pixelization and the sound often stop.

     All my test video are 25~30FPS,4000~5000kb/s,720P or 1080P,and all encode in H.264.

     I use vlc on my PC to be streaming server,and use Gallery on android4.4.2 to be streaming client.

     So,please help me.

All right,I fix it.The problem caused by the tiny UDP buffer.

Change this file:

~/android/external/fsl_imx_omxlib_ffmpeg/libavformat/udp.c

-#define UDP_MAX_PKT_SIZE 65536

+#define UDP_MAX_PKT_SIZE 1048576

     I forget to say,all my test video are play well when they stored in eMMC or played by http protocal.

Hello Iql,

This scenario it is not going to work , because the Android Gallery does not have the feature to receive information through the streaming server, you need an application that handle this feature,  for example adding the VLC client to your android device or any other  APP that handle the streaming functionality

Have a great day,
Jaime
