Thanks, looks like that has now worked.

Worth noting that the recommendation for --demuxer-max-bytes=8092 for MPV comes from the documentation for Streamlink, it may want updating.

It recommends 8192 Bytes because that’s the initial size of Bytes (8 KiB) Streamlink tries to read before it outputs something.

The docs were upgraded earlier this year in https://github.com/streamlink/streamlink/pull/2771/files due to the MPV 0.30.0 release and the affected --cache parameter change: https://mpv.io/manual/stable/#options-cache

But a demuxer that gets choked by a way too low read value is indeed a problem with the documentation. The values should have been updated as well, as they don’t translate directly from the old --cache parameter. Thanks for the hint.
