Most of the code is actually not mine but originated from "Direct264": http://forum.doom9.org/showthread.php?t=152419 https://svn.code.sf.net/p/direct264/code/Patches/ Therefore I've tried to split as best as possible the code I have added.
There are 3 controversial parts in this patch set: - the BSF API change (fixing it is out of my league/time budget) - the filter doing in-place filtering (?) - the level of validation for this new filter I've only tested the cropping feature, and validating that the rest works tenuous. Anyway, cropping is unfortunately not at all well supported: - VLC 2.1.5 (Windows) either crashes or outputs garbage - DXVA on some Intel core gets top/left cropping completely wrong (0,0 but something valid for bottom/right seems to be OK) - ffmpeg-based decoders (e.g. mplayer) are OK It is possible the implementation is incorrect but it was written following the specs.
