i dont know what exactly you mean, could you tell me the subj/date of the
mail where you complained?

if a changes in the source cause some version of gcc to fail (or even all
versions of gcc)
due to a gcc bug, this still is a gcc bug and not one in ffmpeg, as its
not a ffmpeg bug theres no reason why it should be reversed

there is no bug as the mov demuxer correctly ignores width/height for mpeg4
in mov, it didnt at some point in the past and people did send bugreports
so it was fixed ...
but as you are mov maintainer you should know that and not ask me, hey
why not go and read the quicktime spec like you ask me to do with ODML?

well if you want your patch in svn you should help me instead of fight me
