Is FFV1 even used for anything? First time I am hearing about this codec and I have some experience in this area.

From a comment on the article

I love compression, I love ffmpeg and I love more performance, but…
FFV1 is ffmpegs own, old lossless compression format for archival purposes. It is not particularly bad, but it is also not particularly good or modern.

Not like the speed of decoding ffmpeg has ever been an issue to begin with even on ultra-low end cards.

in reply to Nanook

Not for normal playback but in particular ffv1 is used for archival stuff and is IMHO likely to be used with programmatic usage e.g. generating thumbnails for thousands of chapters of video and the like, where decoding speed does matter.

@stevestevesteve Ok granted, a use case I did not think of.
