decode a mp4 video with gstreamer

Question

I want to play a mp4 video in Gstreamer, but i got an error with the x264dec which is not found. I wrote this pipeline

  gst-launch filesrc \
     location=/media/thesis/Gstreamer/pub_Irma.mp4 \
   ! qtdemux name=demux demux. ! queue ! faad \
   ! audioconvert ! audioresample ! autoaudiosink demuxer. \
   ! queue ! x264dec ! ffmpegcolorspace ! autovideosink 

After this step, my aim is to generate execution traces of a mp4 video decoding. I don't know where is the problem with x264dec.

Answer 1

This might be easier:

gst-launch-0.10 playbin2 uri=file:///path/to/foo.mp4

or

gst-launch-1.0 playbin uri=file:///path/to/foo.mp4

(You still need the required elements installed of course).

Answer 2

This command

gst-launch-0.10 filesrc location=/root/gstreamerexamples/big.mp4 ! qtdemux name=demux demux. ! queue ! faad ! audioconvert ! audioresample ! autoaudiosink demux. ! queue ! ffdec_h264 ! ffmpegcolorspace ! autovideosink  

works fine for me.

To play mp4 file take bigBuckBunny mp4 video as test file. Next please sure all the elements mentioned in the gst-launch is built in the x86 or any other target platform.

Please send lot of time in correct installation of GStreamer.
