(which is ridiculous) I have not looked at DVB at all so i cannot comment. if its a mess, the question is in what way it is a mess. FFmpeg should have DVB support in some form. whatever external or internal bits that would use. It should be supported. GNU radio, a different lib, libavradio, a demuxer, a filter in a future avfilter API whatever but it should be supported in some form thx [...] --=20 Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB No snowflake in an avalanche ever feels responsible. -- Voltaire --+r+clu82y77Ss1pj Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABEIAB0WIQSf8hKLFH72cwut8TNhHseHBAsPqwUCZJYQZgAKCRBhHseHBAsP qzSWAJ9rqiQ4UHYUQmqdMGqJenI1jWuH7gCeKCOJTZSaXbCuyR27NW67FNd3vJw= =8oOu -----END PGP SIGNATURE----- --+r+clu82y77Ss1pj-- --===============4626939532019315737== 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". --===============4626939532019315737==--
