The Digital Audiovisual Formats Specialist of the Library of Congress drafted much of this. This happened in part because ffv1 has been seeing increased use within audiovisual archive environments. Also the AudioVisual Working Group of the Federal Agencies Digitization Guidelines Initiative (which runs that site) asked me to present on ffv1 for use in audiovisual preservation a few months back at their annual meeting, which covered some of the new features like multi-threading and embedded checksums. There was also a presentation at the Society of American Archivists conference this year that largely covered the work done by an audiovisual preservation vendor and a municipal archive to adopt ffv1 as an audiovisual preservation format. I'm also teaching a workshop called ffmpeg4archivists at the Association of Moving Image Archivists in December that will cover lossless video handling, ffv1, and framemd5.
I think ffv1 could see much more widespead use particularly within audiovisual archives once version 3 is marked as non-experimental and stable and the specification is finalized. One reason that many archive utilize jpeg2000 for this purpose is because it is well standardized though often less efficient in practical use compared to ffv1. I'm hoping that as ffmpeg and libav continue work to finalize ffv1 version 3 that the codec could see more support in related projects like VLC or mplayer. I'm particularly hoping that the rumored final release of Perian will update it's codec library from libav 0.6 to modern versions to bring more widespread support for ffv1 to QuickTime based environments (like Final Cut and Compressor).
