Error: Registration of the Allocated Frame Buffers Failed

[Wierd O]

Hi all,

I am trying to stream a video( mp4[aac+mpeg 4]) but got the following error. I wonder where the problem might be.

mx27# gst-launch filesrc -v location=/video/sample_mpeg4.mp4 ! mfw_mp4demuxer name=demux demux. ! queue ! mfw_vpudecoder codec-type=std_mpeg4 ! mfw_v4lsink demux. &

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?

As with your other similar questions: you're using private elements
that we don't have source to, and can't debug. You should contact the
vendor, as none of the problem you're encountering are
generic-gstreamer issues, they're solely problems with your
vendor-supplied elements.
