[FFmpeg-user] Size of 10-bit 4:2:2 video streams?

The only occurrence of "non-interleaved AVI" is on avidec.c:

     if (avi->non_interleaved) {
         av_log(s, AV_LOG_INFO, "non-interleaved AVI\n");
and from a quick read of clean_index(), all that's doing is building a new 
index for a given stream. Absent other info, I'm not sure the message is 
more than information.

In theory, avicodec will do it but it's quite old, same for vitrualdubmod 
and gspot (http://www.headbands.com/gspot/), but then AVI format is also 
quite old. I have used gspot before and it was useful, haven't tried it for 
this purpose.

https://greshka.net/avicheck/ has some interesting suggestions, which 
eventually land on.... "ffmpeg -v 5 -i FILE.avi -f null -" (decode to null 
output, turn up the error reporting.

I'll echo Paul's thoughts that the AVI is somewhat corrupt, at least the 
metadata is badly wrong. It's possible that by either poking the metadata to 
"correctness" or ignoring a lot of errors, usable video could be pulled out.
