[Twitch] TypeError when downloading multiple streams

Plugin Issue

• This is a plugin issue and I have read the contribution guidelines.

Description

I’ve got this small application (automatic-twitch-recorder) that checks whether a twitch streamer is online and records them (aka downloads the stream) if they are currently streaming. However, a TypeError is thrown in TwitchHLSStreamWorker whenever a streamer is currently being recorded and another streamer goes online that also is about to be recorded. Recording a single streamer at the same time seems to work fine.

Reproduction steps / Explicit stream URLs to test

1. Download my app, install requirements, … you know the deal.
2. Start atr_cmd.py and daemon.py (you will be asked for your client id and client secret)
3. In atr_cmd.py, add any twitch streamer that is currently online and streaming by typing add <random online streamer #1>, then type start to start the checking & recording routine
4. wait an indefinite amount of time so the download of the stream starts (a folder named <random online streamer #1> will be created next to the *.py scripts)
5. In atr_cmd.py, add another twitch streamer that is currently streaming by typing add <random online streamer #2>
6. Now observe the daemon.py log, see Log output (I added a print statement in process_sequences to log self)

Additional comments, screenshots, etc.

I tried this on Windows while using Python 3.6, Python 3.8. I also tried using the Session object with no luck, though I didn’t use any options. If you’re wondering where I’m using streamlink: see watch method in Watcher.py.

Any help is appreciated, thank you.

@Instinctlol try the git version of streamlink

Thanks, git version seems to work 👍
