Interesting, FATE didn't catch it for me. Which test is it?

$ make fate-adpcm fate-acodec fate-westwood-aud SAMPLES=fate-suite/

All pass for me.


Never mind, found it.

Both the sample from the ticket as well as the fate-sample
(vqa/cc-demo1-partial.vqa) are 22050 Hz, mono, s16; the fate sample is
version 2, the new sample version 0. None of them test the version 3
codepath, so the change to it is untested.

Yeah, don't know where stereo came from. I need to sleep more...

What I meant was see this. Top is before, bottom is after:

I've also confirmed all the "https://samples.ffmpeg.org/game-formats/vqa/Tiberian 
Sun VQAs" samples
exhibit the same behaviour without the patch.

I have tested a few files and the changes to the non-version 3 codepath
seem to be correct; I have also found out that your commit
c012f9b265e172de9c240c9dfab8665936fa3e83 made decoding
https://samples.ffmpeg.org/game-formats/vqa/Tiberian Sun
VQAs/startup.vqa (which is a version 3 format ima-ws file) crash.


I've fixed the crash, see 
https://ffmpeg.org/pipermail/ffmpeg-devel/2021-April/279504.html



Once the patch (and my crash fix) are merged, I'll submit a test case for v3 
VQA files so this doesn't happen again.
