[gst-devel] Error: Registration of the Allocated Frame Buffers Failed

[mattias]

I think you might pay special attention to these lines:


*WARNING: from element /pipeline0/demux: pads are not negotiated!
Additional debug info:
audio pads are not negotiated!
*
Maybe you need to extract the audio from the mp4demuxer as it should 
have two outputs?
