Comment (by giwiniswut):
Today i stumbled upon this as well. Currently the indeo3 decoder appears
to reject resolutions that are not multiples of 8 (as opposed to 4 as OP
experienced).
I removed that constraint from the indeo3.c file and ffmpeg seemed to
convert the affected videos with "faulty" resolutions just fine.
I summarized my findings in this gist on GitHub:
https://gist.github.com/SebiderSushi/be89ede578881f22c66d667e717c9859
I will attach these exact same files here as well, i mainly posted them
inside a GitHub gist to get Markdown formatting.
