I need to sync video and audio when I play mp4 file. How can I do that?

Here's my pipeline:

gst-launch-0.10 filesrc location=./big_buck_bunny.mp4 ! \
qtdemux name=demux demux.video_00 ! queue ! TIViddec2 engineName=codecServer codecName=h264dec ! ffmpegcolorspace !tidisplaysink2 video-standard=pal display-output=composite \
demux.audio_00 ! queue max-size-buffers=500 max-size-time=0 max-size-bytes=0 ! TIAuddec1 ! audioconvert ! audioresample ! autoaudiosink

    Hi,

    Can you please use "sync" arg in your command,

    gst-launch-0.10 filesrc location=./big_buck_bunny.mp4 ! \
    qtdemux name=demux demux.video_00 ! queue ! TIViddec2 engineName=codecServer codecName=h264dec ! ffmpegcolorspace !tidisplaysink2 video-standard=pal display-output=composite \
    demux.audio_00 ! queue max-size-buffers=500 max-size-time=0 max-size-bytes=0 ! TIAuddec1 ! audioconvert ! audioresample ! autoaudiosink sync=true

    gst-launch-0.10 filesrc location=./big_buck_bunny.mp4 ! \
    qtdemux name=demux demux.video_00 ! queue ! TIViddec2 engineName=codecServer codecName=h264dec ! ffmpegcolorspace !tidisplaysink2 video-standard=pal display-output=composite \
    demux.audio_00 ! queue max-size-buffers=500 max-size-time=0 max-size-bytes=0 ! TIAuddec1 ! audioconvert ! audioresample ! autoaudiosink sync=false

    Yeah, I've already tried that. Didn't help.

    Hi,

    Have a try to use args "sync=1 qos=1"  to address your sync issues.
