Description

Summary of the bug:

ffmpeg refuses to process Indeo3 resolutions not a multiple of 4. Attached is a video extracted from a game that appears to have such a resolution

How to reproduce:

Attempt to play attached video. Video extracted from a game via

ffmpeg -i SCIGUY.MOV -c copy

(and some manipulation of that file's first few bytes to extract different videos. Note that this process has, in fact, resulted in valid videos, see https://github.com/Sgeo/therock_decoder ) 

ffmpeg version:
