how to use ffmpeg to encode videos with hsv colorspace

The EOTF/tone curve is arib-std-b67 (HLg) ( -color_trc).The primaries are bt2020 ( -color_primaries).The YUV RGB color matrix is bt2020nc ( -colorspace).For example, when you see something like gbrp10le(tv, bt2020nc/bt2020/arib-std-b67) for the input or output stream, this means: The output of FFmpeg reports what it knows for each stream. They actively change the pixel values and layout in memory. The various -vf options are there to convert between colorspaces. As far as I know this alone doesn't modify the pixel values either. x264-params and -x265-params do that manually. Some codecs or formats also need to know what colorspace they're operating in because they need to insert that in the encoded stream, and sometimes FFmpeg doesn't pass what it knows. As far as I know this doesn't modify the pixel values themselves. They don't do any conversion on their own, they just tag the input or output stream (depending on whether they're placed before or after -i). pix_fmt, -colorspace, -color_primaries, -color_trc and -color_range are for setting values inside the AVFrame structure described here. This might not completely answer your questions, but I found the intricacies of FFmpeg and libswscale and the various filters to be not very well-documented, so here goes my understanding of the thing. However colorprim=bt709, transfer=bt709, colormatrix=bt709 all work. With Codec Params -x264-params 'colorspace=bt709', I get Error parsing option 'colorspace = bt709'. There are no Normal -all or -colormatrix options, but there are all= and colormatrix= for -x264-params and -vf. Should I use normal options or -vf instead for vp8 and other codecs? There is no -vp8-params, only -x264-params. When should each be used when encoding from raw, or transcoding/converting from one format to another? Such as mpg to mp4.ĭo I need to specify the input colorspace or will FFmpeg auto-detect? Codec Params -x264-params 'colorspace=bt709'.I'm trying to understand the difference between Colorspace FFmpeg arguments:
