 Hi.

 I have an MP4 file (that I can upload, if desired) that is not recognized
 by ffmpeg, but can be played without any problems with mplayer2.

 I am using a Debian sid environment (with some packages taken from deb-
 multimedia, to get real ffmpeg, not libav).

 Here is the debug output:

 This is, BTW, only one file from a handful of other files (from the same
 batch) that aren't recognized by ffmpeg.

 I don't know exactly which extra information to include, but, please, let
 me know what else is needed and I will do my best to provide it (and this
 includes, as I mentioned, uploading the file to your FTP server).


 Thanks in advance.
