Quote from: Cormy1 on September 19, 2020, 04:56:35 pmWould it be possible to get a similar function in Avidemux so that we can edit audio on "keyframes" just as we do video without needing to re-encode?
Quote from: Cormy1The primary purpose of this is for importing external audio tracks that need to be offset by a greater value than permitted in Avidemux.
ffmpeg -ss <offset in seconds> -t <duration in seconds> -i <input audio file name.extension> -c copy <output audio file name.extension>
Quote from: Cormy1 on September 19, 2020, 04:56:35 pmWhen video is edited in copy mode, what happens to the audio in copy mode? Is it also cut on audio frames and then accordingly offset or does the entire audio track remain intact while being offset to match the cut duration of the video? Especially when shift is applied, I'd assume the entire audio track is still retained while simply being shifted in playback.
Quote from: Cormy1 on September 19, 2020, 04:56:35 pmA visual audio reference track like that in MP3DirectCut would also be tremendously helpful, since audio playback always mismatches video playback that doesn't match AviDemux's playback rate (again this 60fps video problem vs 30fps playback)
Quote from: Cormy1 on October 02, 2020, 04:41:33 pmI just mean playback speed is capped at 30fps

Quote from: Cormy1 on October 11, 2020, 01:05:17 pmOn AVI muxer I see it encoding about 45 frames/second.What does this mean?

Quote from: eumagga0x2a on October 19, 2020, 12:45:58 pmCould you please retry with DXVA2 decoding disabled?
Quote from: Cormy1 on October 21, 2020, 01:54:23 amDoes sdl driver matter?
Quote from: Cormy1 on October 22, 2020, 07:06:08 pmThat solved it. Why would I be getting this behaviour?
Quote from: Cormy1 on October 22, 2020, 07:06:08 pmsomeone sent me an interesting WebM whose playback frame size seems to change dynamically?
