You could try `-http_multiple 0` to avoid prefetching segment while reloading playlist. But I doubt it will actually help. Both mpv and FFmpeg try to read segments as fast as possible, which probably trips the server and its rate limiting. If I were to guess, maybe `--no-cache` in mpv, or smaller cache could help. In ffmpeg `-re` or other rate limiting option to keep the rate of reading in acceptable by server range. Since I don't know how strict the server is, suggesting a single solution is difficult. - Kacper _______________________________________________ ffmpeg-devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
