"To delay the audio stream" means to insert several audio samples of silence into the audio stream. It is quite easy to do using [setpts filter](https://ffmpeg.org/ffmpeg-all.html#setpts_002c-asetpts). But this works only for the whole audio track.
If you need to add delay in the middle of the audio track, then probably you should do the following steps: - extract and save the first part of audio track (for example, using [-t option](https://ffmpeg.org/ffmpeg-all.html#Main-options)) - extract and save the second part of audio track (for example, using [-ss option](https://ffmpeg.org/ffmpeg-all.html#Main-options)) - generate desired number of audio samples containing silence (for example, using [anullsrc filter](https://ffmpeg.org/ffmpeg-all.html#anullsrc)) - concatenate the first part, the silence part and the second part (for example, using [concat filter](https://ffmpeg.org/ffmpeg-all.html#concat-3)) - mux original video and newly created audio tracks in the final file > > Am 25.04.25 um 20:47 schrieb tasos: > >> Hello. > >> I would like to ask if it is possible to delay the audio streams of a > >> video , but for a specific time range. > >> Something like using -ss -to combined with -itsoffset. > >> More specifically from half-till the end of the video. > >> Thanks! _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
