[Gstreamer-openmax] GstOpenmax demuxer issue

[prafull singh]

Hi Felipe,

 Thanks for your suggestion.
 Now I'm able to play only audio and only video file with my own OPENMAXIL
decoder and render component. But still I'm facing problem while playing
video file containing both audio and video then video and audio are not in
sync either video is not able to play totally and audio we can play or
listen. I'm using following command-

gst-launch -v filesrc location=/home/prafull/downloads/sample_iPod.m4v !
qtdemux name=demux {demux.audio_00 ! queue ! omx_aacdec ! omx_audiosink}
{demux.video_00 ! queue  ! omx_h264dec  ! omx_videosink}

Output-

Here render is getting data from both audio and video decoder but after
sometime it is going to hang on handle_event newsegment and tag. Can you
please tell me what can be the reason for not being able to play both audio
and video.

Thanks.
Regards
Prafull
