hello Tim,

With the following chain it is working fine.

gst-launch filesrc
location=/media/sdmmc0p1/MPEG4SP_MP3_512kbps_25fps_QVGA_WilsonWar.avi  !
avidemux name=demux { demux.video_00 ! queue ! omx_mpeg4dec ! autovideosink
} {demux.audio_00 ! queue ! omx_mp3dec ! audioconvert ! audioresample !
volume ! autoaudiosink }

Please find attached log with "export GST_DEBUG=GST_ELEMENT_FACTORY:3" with
playbin.


I have one doubt in playbin what are 'preroll_video_src0' and
'preroll_audio_src1' elements which are added? How they can affect? Is there
anyway to disble these elements while using playbin?


Rgds,
Gulshan
