Description

whilst watching a stream the UI will apper as if it has hanged, but from the bug reporting in Fedora says it has streamlink-twitch-gui killed by SIGABRT, the stream continues. The tool has made this backtrace https://paste.ubuntu.com/p/JYsq9f4dmZ/, and there is a coredump that i can share if needed

Expected / Actual behavior

not causing a SIGABRT to happen

Reproduction steps

1. launch stream

3. try and use the UI agian

Hi, I've seen your messages on Gitter yesterday, but haven't had the time responding yet, sorry about that.

Regarding your issue, unfortunately I can't tell you why the Twitch GUI is freezing on your system and then is getting killed via SIGABRT by libc. Remember that it is an NW.js application and just a launcher for Streamlink/Python. If there's an issue regarding system libraries, this have to be solved on the NW.js side and can only be fixed here (if it's indeed an issue) by upgrading the NW.js platform to a newer version.

If you launch the Twitch GUI with the --loglevel debug parameter, you can see the generated Streamlink launch parameters in stdout or ${XDG_DATA_HOME:-${HOME}/.local/share}/streamlink-twitch-gui/logs/.

Since you only seem to encounter this freezing issue while watching streams, did you consider that it might be a memory or GPU related problem because of the player process? The Twitch GUI has nothing to do with watching streams or even launching the player...

So, which player are you using? Please try out MPV with the custom --no-video or --no-video --force-window parameters and see if this causes it to freeze, too.
Other than that, you can try launching the Twitch GUI without GPU acceleration. As I've said, it's a NW.js application, therefore all Chromium parameters are available. See the --disable-gpu{,-*} parameters here:

streamlink-twitch-gui/lib/libnode.so

As I've said, I can't do anything here other than upgrade the currently used NW.js version (0.26.6).

I've pushed a new branch nwjs-upgrade as an upgrade of the previous nwjs-0.31 branch to the repo. Please see if this works for you. Build instructions can be found in CONTRIBUTING.md.

The previous upgrade attempt had some issues which was the reason I didn't merge it. Those issues seem to have been fixed or at least reverted. However, there are a couple of new issues, like the smooth scrolling. Make sure to back-up ${XDG_CONFIG_HOME:-${HOME}/.config}/streamlink-twitch-gui or use the --user-data-dir=DIR launch parameter when switching between non-master NW.js versions of Streamlink Twitch GUI.

Edit:
Oh, and the start.sh bash wrapper has been removed, since it's not needed anymore. So if you've created a menu entry, you should remove it first before upgrading.

Same problem here. Random hangs while playing a stream and random crashes while doing nothing in the background.

Yes, I am aware that you can't run the currently used NW.js build on the latest Fedora release. See my post above and follow the instructions. You need to build the app from the nwjs-upgrade branch, which uses a more recent NW.js build that should work on the latest Fedora release.
#603 (comment)

[OlliC]

So i have built this version now and indeed it seems to be fixed. Any idea when this will be in the regular version?

[bastimeyer]

I haven't had the time and motivation to work on Streamlink Twitch GUI in the past weeks.

A couple of things have to be fixed and changed first before I'll be able to publish a new release. The new NW.js version which you are using right now has a few issues which have to be resolved (or they'll have to be ignored for now) and I'm also waiting for the Streamlink 1.0 release.

[OlliC]

No problem. Thank you anyway. I will then just use my own compiled version until there is a new release.

[bastimeyer]

#615 has just been merged.

There are still a couple of things for me to do before I'll be able to publish a new release. I'll keep this thread open until then. So if someone has issues running the current release, please build from the master branch.

v1.7.0 has just been released:
https://github.com/streamlink/streamlink-twitch-gui/releases/latest

It uses the latest NW.js stable version based on Chromium 73
