Hello,
I am trying to display subtitles on a imx6 solo based board with
gstreamer0.10.
The setup is the following:
rootfs built with yocto master-next, image based on fsl-image-multimedia,
and MACHINE is imx6solosabresd.conf, linux kernel is 3.10.31 BETA.
I have a AVI file which contain 6 tracks : 1 video, 3 audio and 2 subtitles
which I am streaming in multicast
I am using the following gstreamer command line to display video and
subtitle without audio for the moment:
gst-launch udpsrc multicast-group=239.255.42.1 port=1234
caps='video/mpegts, systemstream=(boolean)true, packetsize=(int)188' !
aiurdemux name=demux demux. ! queue ! h264parse ! vpudec low-latency=true !
dvbsuboverlay name=overlay ! imxv4l2sink demux. ! "subpicture/x-dvb" !
queue ! overlay.
In results, I have the following traces and nothing on the screen:

I note that the demuxer "aiurdemux" don't see subtitles tracks.
What can cause this kind of problems?
