- JimDabell 11y agoChromakey was introduced in 2.8.x.
- ericmo 11y agoIt's in the official changelog as a new feature: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=blob;f=Changelog;h=2e1cd36f5fe9cce3880697ddfe3079c0b1654473;hb=c40983a6f631d22fede713d535bb9c31d5c9740c http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;...
- JimDabell 11y agoApologies, you're correct. I was thinking of the colorkey filter: https://ffmpeg.org/ffmpeg-filters.html#colorkey https://ffmpeg.org/ffmpeg-filters.html#colorkey This was introduced in 2.8 and does the same thing as chromakey, except in RGB rather than YUV.
- Veratyr 11y agoIs Intel QSV available on Mac/Linux yet by any chance?
- tmm1 11y agoThere's a patchset for this feature being discussed on the mailing list: http://ffmpeg.org/pipermail/ffmpeg-devel/2016-February/189533.html http://ffmpeg.org/pipermail/ffmpeg-devel/2016-February/18953...
- willkelleher 11y agoFFmpeg on Linux supports QSV either through the h264_qsv encoder or through some soon-to-be-merged va-api changes. On Mac I think you need to use the VideoToolbox API to access the GPU codec, and there is support for this in FFmpeg as well, but I haven't used it myself.
