I have been unable to easily make webms though mpv-webm as I would with non-stream media.

I have a live stream running via Streamlink in MPV. Player input is set to HLS. I clip the segments of the stream I wish to make a webm from. While encoding the progress is stuck at 0%. A cache_dump.ts is successfully created in this process.
I've been able to semi-successfully make webms by killing the MPV window with the stream running but the clip points are wrong and having to close MPV in order to make the clip isn't ideal.

Log is an attempt at creating a webm from a livestream , being stuck at encoding 0%, attempting to exit out of MPV, and finally killing both the MPV process of the stream and the one encoding the webm

I hope this gets fixed. It was the best way to clip streams.

• tested youtube and twitch
• --no-config, default settings for mpv and script
• removed id, sig, vo, vd, vf, ad, ao, osd from log
