Adding a 3rd entropy coder is outside the scope of implementing float suppo= rt If such a encoder makes sense, that should be a seperate thing. And if you belive it performs better than what we have, submit a patch and benchmarks. Please make sure only to use material free of patent issues, aka things that predate patents in a way that invalidates the patents thx [...] --=20 Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Let us carefully observe those good qualities wherein our enemies excel us and endeavor to excel them, by avoiding what is faulty, and imitating what is excellent in them. -- Plutarch --u4MMvwPV8xYJuRB6 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABEKAB0WIQSf8hKLFH72cwut8TNhHseHBAsPqwUCZ8pEzgAKCRBhHseHBAsP q/9QAJ9b2E8eknSkOnl7eZEy1fSBlzs9WACfaiBY6cdhlv93VYRfKkofOyqy8yA= =wapF -----END PGP SIGNATURE----- --u4MMvwPV8xYJuRB6-- --===============1852727813654063432== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe". --===============1852727813654063432==--
