all files i have (not many ...) either play perfectly with ffmpeg or
they arent playable with libtheora at all

ive also confirmed that the input to the idct is binary identical
to the reference for the one file which had artifacts with ffmpeg
until a few hours ago, the idct should also be identical as it
is copy & pasted from the reference IIRC

so IMHO if noone finds a theora file which can be played with libtheora
but not with ffmpeg, then libtheora support should be dropped its one
dependancy less ...

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
