[FFmpeg-user] Combining -copyts with segmentation gives unexpected results

I try to record an opus stream into segment files while retaining timestamps. But ffmpeg creates a lot of very small files much faster than what I set for -segment_time. Latest ffmpeg version that I tested was 5.1.1. My command is something like ffmpeg -i somestream.opus -c copy -copyts -f segmen

Ok, here is an example command: $ ffmpeg -i http://volosatoff.ru:8008/euro.opus -c copy -copyts -t 25 -f segment -segment_time 10 -reset_timestamps 0 -strftime 0 recording-%05d.opus Output in terminal: ffmpeg version 4.4.2-1sergeyd9.9~18.04.1 Copyright (c) 2000-2021 the FFmpeg developers built

[FFmpeg-user] Meaning of duration

Suppose you have recorded an Opus stream with -copyts. Then ffprobe -v error -show_entries format=start_time,duration -- recording.opus shows non-zero start_time and possibly huge duration that does not reflect to the file size. I think you get the actual duration of the recording by subtracting

[FFmpeg-user] Handling alternating stream title and similar metadata

Some audio streams may have StreamTitle metadata that will change from time to time. How do you record that changing information so that you can later show the title when the recording is being played? Are there some standard tags that can be used to denote e.g. current program name or current song

[FFmpeg-user] Ssegment with ogg/oga?
