Description
1) What you were trying to accomplish
I am trying to transcode an interplayacm ACM file to a pcm_s16le WAV file.
2) The problem you encountered
I have encountered an error while decoding the interplayacm audio format. I get this error with some but not all ACM files I have tested. The game this file came with and legacy decoders can properly decode and play the file, so the file itself is not corrupt. I am happy to help debug this issue in any way I am able, including providing additional sample files that do and do not produce this error and testing potential fixes. The error in question includes:
Error while decoding stream #0:0: Invalid data found when processing input
Last message repeated 20 times
[interplayacm @ 00000273542efa80] Too many errors when draining, this is a bug. Stop draining and force EOF.
Error while decoding stream #0:0: Internal bug, should not have happened
3) The exact command line you were using
ffmpeg.exe -report -v 9 -loglevel 99 -i interplayacm_decoder_produces_error__Bc1a3.acm Bc1a3_ffmpeg.wav

5) Sufficient information, including any required input files, to reproduce the bug and confirm a potential fix.
See interplayacm_decoder_produces_error__Bc1a3.ACM
for an ACM file that produces the error.

Interplay ACM to WAV converter v1.32, (c) 1999-2003 ABel [TeamX]
acm2wav.exe
I can provide a download link to a precompiled windows binary, but AFAIK the source code is not publically available online.
Near Infinity can also decompress it to a WAV file. The results are identical to acm2wav.exe except that it leaves out the extraneous LIST chunk at the end. It is open source (Java): https://github.com/NearInfinityBrowser/NearInfinity/blob/devel/src/org/infinity/resource/sound/AcmBuffer.java
