Play mp4 (h264 + aac)

Dmitry Mikhaylov1

Could anybody provide working pipeline for playing video and audio from mp4 file?

I've tried this which looks pretty much line in wiki pipelines examples, but it is not playing anything:

gst-launch -v filesrc location=/home/root/big_buck_bunny.mp4 !
qtdemux name=demux demux.audio_00 ! queue max-size-buffers=8000 max-size-time=0
max-size-bytes=0 ! TIAuddec1 ! alsasink demux.video_00 ! queue ! TIViddec2 fram
erate=30 ! TIDmaiVideoSink videoStd=D1_PAL videoOutput=composite

Here's the output:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
/GstPipeline:pipeline0/GstQueue:queue1.GstPad:sink: caps = video/x-h264, profile=(string)main, level=(string)3.1, codec_data=(buffer)01

I've also tried this pipeline:

gst-launch filesrc location=/home/root/big_buck_bunny.mp4 ! qtdemux name=demux \
demux.audio_00 ! queue max-size-buffers=1200 max-size-time=0 max-size-bytes=0 ! TIAuddec1 codecName=aacdec engineName=codecServer ! alsasink \
demux.video_00 ! queue ! TIViddec2 codecName=h264dec engineName=codecServer ! TIDmaiVideoSink videoStd=D1_PAL videoOutput=composite useUserptrBufs=true numBufs=4

It just freezes on:

Hi,

What processor are you using?

Have a try,

gst-launch-0.10 filesrc location=sample1.mp4 ! qtdemux name=demux demux.audio_00 ! faad ! alsasink sync=false demux.video_00 ! queue ! ffdec_mpeg4 ! ffmpegcolorspace ! fbdevsink device=/dev/fb0

gst-launch-0.10 filesrc location=sample1.mp4 ! mpeg4videoparse ! ffdec_mpeg4 ! ffmpegcolorspace ! fbdevsink

gst-launch-0.10 filesrc location=sample1.mp4 ! decodebin2 ! autoaudiosink

gst-launch-0.10 filesrc location=h264_720p_hp_5.1_6mbps_ac3_planet.mp4 ! decodebin2 ! autoaudiosink (only audio)

Hi,

I use DaVinci DM365 and obviously there is no faad or ffdec_mpeg4. It should use its own codecs.

When I do something like

 gst-launch-0.10 filesrc location=./big_buck_bunny.mp4 ! \
     qtdemux name=demux demux.audio_00 ! queue ! TIAuddec1 ! audioconvert ! audioresample ! autoaudiosink

Without video I can at least hear the sound from video.

Ok, here's pipeline that at least works for me:

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=8000 max-size-time=0 max-size-bytes=0 ! TIAuddec1 ! audioconvert ! audioresample !         autoaudiosink

Hi,

Good to hear this,

Thanks for your update.

Some more useful links for your processor, so others get benefited.
