I do not object to this patch nor the one to concat, but I want to state once again: The authoritative source of information about frame durations in libavfilter, be it internally for the caller, is the timestamp of the next frame, or the timestamp of EOF for the last frame. Filtered frame durations are only a hint. --=20 Nicolas George --ROOZuCJnnaZhE55n Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE6ooRQGBoNzw0KnwPcZVLI8pNxgwFAmRGWGcACgkQcZVLI8pN xgzZFhAAqEavKEMsSao3rL2lNsZVPU0qD8Jx+58agePwuVI1Oy4xfo+MLbcBa02X X3grrNvLO5bqxBe2RDvFOr7Wi5ALkouRvMjLhcuzM43IlSlPM7nhP6cvSeP5c1lY LVsbyTUIOD0U50kB6M0G3gp6BpY/rvfwN/P7aUhlVHzG7KL+E8fzBXeR1RbbzxAb Gf6iHPlSTg6lmBEpx9i/UP/XRPhSD2l0iCeTDcQKK4G4OZLaxR6y30jHLvpRij1w JXxtBYl8SBBboMjAdQ+dHhQ9vx3KoQHLiZVg8ebvY0+wHUifWdZte2ZvsaeZS8C5 RgDOR/sKlx1zSX4JjAUy5zKGYqbPtvY7OY0+uW8fqK7CIjMXf4NWAuFpis3bCH/O 5fC2qEmWtcZ4rmAqR/SJEbhjYutS9B2an6sVPOLbEzvAyWXrJ78V2I79AlAl9q9o 0XjQ+CEkZcT9PP6pzsxUeWufQ9ZZPRhgkkCKDGrLbJ5izgA5ITMSjqfX7+iIf6Vr thZ/PH/U/1t+oNmnBbv0Z3gPt16p+GgGL1j4lUf1LoQiklYXYiKSqD4u6ZzVubhx FGsk0ocHZKvgM1z1kqE33a6PlPIj1xywLY5sFCG4t6G9uRkAqMfTGDJbmo6L9fIV +vhzcGB/ldFPgommlFLhckjrc4jAKgx2CRaC7G6iaYHKVnkAKMI= =JvlA -----END PGP SIGNATURE----- --ROOZuCJnnaZhE55n-- --===============2722623269605558369== 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". --===============2722623269605558369==--
