Problem with ffdec_mxpeg

[lestoilfante]

Hello, I have the following pipeline with the attached fail report, I
think some kind of element is missing in my pipeline. My goal is to be
able to play a live mxpeg stream from a mobotix camera but I really
can't find any documentation about that, any help is very appreciated.

Thank you

FYI

There is also a patch available in bugzilla for integrating mxpeg
decoding in jpegdec. I've been using it for a while.

Yes I already find that but my best choice at this moment is to work
with standard gstreamer bundle.
Anyway is it audio decoding supported on that patch?
Thank you

mxpeg is video, not audio. audio will be in some other format. I'm a bit
suprised that mxpeg is still being used, it's not a very good codec.

From my understanding audio data could be added to mxpeg to include
audio captured from camera internal microphone.
