Hi, Out of curiosity, has there been any progress since 1 year about this topic?
Really, millions of CPU-hours are probably wasted to reencode already-perfectly-encoded content, just for cutting purposes. For example, is there a way to cut a AVI or MKV H264 video with a specific starting point and specific length, with minimal re-encoding? When using: "ffmpeg -ss 120 -t 60 -i input.mp4 -c copy output.mp4", the result is often choppy or non-smooth in the first seconds, because the cut point doesn't necessarily coincide with a keyframe, at least on some players. We could reencode just the beginning until the next keyframe, and then use copy codec for the rest of the video, and then concatenate, but nobody does this, it's unnecessarily complex (and I'm not even sure it works). 20 Aug 2024, 22:34, mich...@niedermayer.cc wrote: > Such signalling can be added to existing containers with little effort. > Iam also happy to help to add it to nut Can you explain with a little bit more details how it would work? Thanks in advance!
