decode a mp4 video with gstreamer

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.

Solution

  • I don't think there's a x264dec element (I only know of the x264enc element). You might want to use ffdec_h264 like in this nabble post:

    gst-launch-0.10 filesrc location=$1 ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! deinterlace ! xvimagesink
