mpeg4 over udp 不工作

[yuantiantang]

环境：

kernel: 3.10.53

yacto 编译出来的rootfs.

PC中VLC做为udp服务器。

开发板为：imx6q

用下面的命令播放H264和mpeg2的音视频文件都正常，但播放mpeg4的音视频时，屏幕没有任何输出。

请帮忙看一下，非常感谢！

root@imx6qsabresd:~# gplay-1.0 udp://192.168.1.108:1234/

playbin is employed!

it's strange, if you use udp, you should use broadcase address, I test on my side, it's ok, my command is:

gst-launch-1.0 udpsrc do-timestamp=false uri=udp://10.193.101.255:10000 caps="video/mpegts" ! aiurdemux streaming-latency=400 name=d d. ! queue ! vpudec ! queue ! overlaysink sync=true d. ! queue ! beepdec ! pulsesink sync=true

then on pc side, you set the correct port and address
