Vitor <[email protected]> added the comment: I've tracked it down to libavcodec/simple_idct.c. Very likely wmv2 send too big values to ff_simple_idct_* leading to some overflow in internal iDCT calculations (simple_idct is know to give arch-dependent results for some inputs, see http://multimedia.cx/eggs/350-tests/#comment- 150877).
Since I don't know basically nothing about wmv2, I'll leave this bug to the experts... ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue2178> ________________________________________________
