Unofficial VirtualDub Support Forums > Testing / Bug Reports > Acm Reported Error On Audio Decompress (200)

This seems like a tough one to duplicate, and I have no idea what caused
it, but I think it deserves a report.

Captured an .avi with VirtualDub 1.5.1, and then processed it with DivX
5.0.3 for video, and normal (no enhanced bitrates) MPEG Layer-3 audio.

When I played back the file, I jumped around (as I usually do) to check
the fades. I came across one particular frame (that looked normal), where
if I tried to start playing from that exact frame, I got the above message
(ACM reported error on audio decompress (200)).

I did not enconter the error starting on any other frame. I could move back
a few frames, and play right through the frame in question without any
problem. VirtualDub 1.4.13 behaved similarly (the same error message
when starting to play on that exact frame). I have never seen this error
before. I reprocessed the audio and video, and the new .avi file did not
have this problem.

I don't have (that I know of) another media player that reports frame
numbers, so I can't (easily) check this on other media players. Knowing
that I could have bad spots in my output does seem a little disconcerting,
though.
