[FFmpeg-user] Decoding adpcm_psx

[Markus Laaja]

Greetings.
In short, I'm running into constant input errors when trying to decode 
from different adpcm formats.
Compiling ffmpeg on a linux environment to see if it helps, is way 
beyond my reach just to solve this, unfortunately.
Can anyone confirm this shouldn't happen?
Thanks for everyone in advance.

The input and output cut short:

--- It's the same with other adpcm formats, it seems.
