Is it possible to apply filters (-vf) in ffmpeg only for selected frames? E.g. to apply a filter for first ten minutes and not apply for the rest of movie? I'm now solving a problem of badly deinterlaced movies, which have some parts not deinterlaced while the rest is. I didn't find this possibility in man page so I assume it's not supported (yet). Is it possible to add the support for example in this form: ffmpeg ... -vf yadif=0-10:00,20:00-30:00 ... to get only first and third 10 minutes deinterlaced? Thank you in advance. Reproducible: Always Actual Results: Deinterlacing for the whole movie. Expected Results: Deinterlacing for selected parts of a movie.
I'd mark this INVALID because this isn't a forum where you post your general questions. Instead it's UPSTREAM because you're asking in the wrong place, too. You might ask on https://forums.gentoo.org/ if you like. Or pick an appropriate IRC channel or mailing list for your questions.
I'm sorry for the wrong place: I thought it's more an extension bug than asking for help. But I was totally wrong. The asked possibility has already been in ffmpeg-2 (Timeline-editing [1]) and more, there's very helpful filter ident [2]. Thank you for saying nicely and thanks to ffmpeg-user mailing list [3,4].
