Please describe the problem:
I have some mkv files, and those are contained xvid video stream and aac audio
stream.

but during play some of those files with totem, shows popup error dialog that
says "Could not decode stream."

after set GST_DEBUG=faad:4 these messages are printed.

gstfaad.c(1324):gst_faad_chain:<faad0> error: Failed to decode buffer: Invalid
number of channels



Steps to reproduce:
I can't dump aac stream from mkv file. anybody can tell me how I can get aac
stream from mkv file?

Actual results:
totem shows popup dialog that says can't decode.

Expected results:
play anyway.

Does this happen every time?
yes.

Other information:
in mplayer, it shows this message, but play anyway.

FAAD: Failed to decode frame: Maximum number of bitstream elements exceeded

In mplayer source, if error were occured, continue decoding anyway.

after I avoid goto decode_error in ext/faad/gstfaad.c:1211, totem plays file
properly, too.
