Comment (by haasn):

 As of 5cfeaeef0c2e0970f64d3188375a525c17f4621b you can now also generate
 ICC profiles from scratch, using a new video filter, vf_iccgen. (Requires
 ffmpeg built with support for lcms2)

 In the case you describe (i.e. transcoding a video with known primaries)
 you can simply add a `-vf iccgen` somewhere in your video chain. It will
 automatically generate an ICC profile for the tagged video color space.
 (And is, by default, a no-op for files which already have embedded ICC
 profiles in them)

 For the example in the OP, you would either need to manually tag the video
 stream (`vf_setparams` or using input options), or specify the explicit
 color space you want as options to `vf_iccgen`.

 I may reconsider my opinion on whether or not the png/jpeg encoders should
 automatically generate ICC profiles on encoding, but for the time being I
 think a video filter is a good compromise.
