Ok, I compiled now from SVN with the default options ("./configure" without arguments).

I get:
jan@MacBuntu:~/linux/ffmpeg$ ffmpeg -i /media/Synology/The\ Matrix\ -\ HD\ 720p\ x264.mkv
FFmpeg version SVN-r15935, Copyright (c) 2000-2008 Fabrice Bellard, et al.
  configuration:
  libavutil 49.12. 0 / 49.12. 0
  libavcodec 52. 3. 0 / 52. 3. 0
  libavformat 52.23. 1 / 52.23. 1
  libavdevice 52. 1. 0 / 52. 1. 0
  built on Nov 25 2008 17:23:31, gcc: 4.3.2
/media/Synology/The Matrix - HD 720p x264.mkv: memory allocation error occurred

Cutting down the file into a smaller as described on the link makes the recognition work, so I cannot provide a sample file:

jan@MacBuntu:~$ dd if=/media/Synology/The\ Matrix\ -\ HD\ 720p\ x264.mkv of=/home/jan/Desktop/sample-file.mkv bs=1024 count=10000
10000+0 records in
10000+0 records out
10240000 bytes (10 MB) copied, 4.33087 s, 2.4 MB/s
jan@MacBuntu:~$ file -i /home/jan/Desktop/sample-file.mkv
/home/jan/Desktop/sample-file.mkv: application/octet-stream

But that means, it must be the big size of the file, that causes the problem (ffmpeg -i on all the other files in my media library worked).

Now the desired gdb ffmpeg_g output:

jan@MacBuntu:~/linux/ffmpeg$ gdb ffmpeg_g

The program has no registers now.

(Didn't seem to work very well though, as the registers are all empty... Maybe a 64-bit problem?)
