3.6 MiB -> un-7-ZIP -> 20 MiB YUV4MPEG 320x175 18 seconds (truncated) Decoded from FLV with MPL 2009 Jan

BUG 1: plays badly in the very same MPL. Strangely, the damage occurs while playing, not decoding, the very same YUV file plays well in my own player (tuned using this file ;-) ).

BUS 2: FFMPEG crashes (Page fault) when trying to encode this file into various codecs including but not limited to Theora. Should be safe to reproduce, at worst I could provide crash report + disassembly, but no mapping into the source.

I assume both effects are related to the very same fact that height is odd - 175 pixels.

BTW, any good YUV4MPEG spec around ? What I found so far is lousy, no hint about how to deal with odd height, even less odd width ...
