Streamlink version
Latest stable release
Description
I am using a Debian 11 stable with kernel 5.10 as you can see in the debug log below.
Tried to send this URL: https://videodelivery.net/9fb3596948ddf463fde0ec4b85625b24/manifest/video.m3u8 that has independent segments for audio and video. Streams were closed, does not start re-muxing.
Cmdline used:
streamlink --stdout hls://https://videodelivery.net/9fb3596948ddf463fde0ec4b85625b24/manifest/video.m3u8 --default-stream best --loglevel debug | ffmpeg -re -i - -c copy
