Description Bastien Nocera 2006-11-13 16:09:40 UTC
Download the file from:
http://www.megaupload.com/?d=4HGMAIVS

It's supposed to be "AAC+SBR" audio. The file shows up as having no audio at all, and an error on the command-line:
** Message: don't know how to handle audio/x-unknown

Also a problem with the fluendo isodemux plugin by any chance?

Audio streams are detected fine for me with qtdemux from -bad CVS (something not entirely right with the number of channels though, but there's a bug for that already somewhere).

Comment 2 Bastien Nocera 2006-11-14 11:46:58 UTC
It's an mkv file :)
I'm using gstreamer-plugins-good-0.10.4-1.fc6
Comment 3 Tim-Philipp Müller 2006-11-14 14:05:39 UTC
Sorry, thought it was the same file as in the other bug report (I did wonder about the A_AAC bit though ;)).

Looks like AVI-Mux can produce files like this (according to http://www.alexander-noe.com/video/amg/en_output_options_mkv.html). This is broken according to the matroska spec as far as I can see, but what can you do *sigh*

Comment 4 Tim-Philipp Müller 2006-11-15 11:20:00 UTC
Seems to be an addition to the official spec. Fixed in CVS:

          Handle opaque/unspecified A_AAC audio codec ID (fixes #374737).
