Streaming does not start throwing an unclear error. When there is a symbol " / " " | " in the title

Bug report

+- [ ] I understand the difference between Streamlink and Streamlink Twitch GUI. +- [ ] This is a bug report and I have read the contribution guidelines.

Environment details

Operating system and version:

Win7sp1

Windows version streamlink-portable-2.0.0-py3.6.5-win32 + streamlink-twitch-gui-v1.11.0-win32

Description

This bug has been around since version 1.3.1. Unfortunately, it has not been fixed.

But I noticed that it happens with streamers who have in the title " / " and/or " | ".

On other streamers, which do not have it in the title all works.

Expected / Actual behavior

Reproduction steps

It looks like this https://dl.dropboxusercontent.com/s/6dqsbe54viurtzz/2021-03-07_17-53-41.mp4

I think it's a mistake not streamlink.

Not a Streamlink Twitch GUI issue.

Don't use the .bat file and instead choose the Streamlink (Python) streaming provider and select the pythonw.exe as python executable and streamlink-script.py as streamlink entry script.

@bastimeyer Thank you very much, I need to create bug reports on their pages ?

https://github.com/streamlink/streamlink or the one that builds the portable version?

[bastimeyer]

I've already linked the bug report which I've opened myself a month ago on the beardypig/streamlink-portable repo.

The issue is caused by incorrect variable expansion in the wrapper launch script. I don't know Windows batch scripting, so I can't submit a pull request to fix it. If it's similar to BASH, then replacing %* with "%*" should fix the issue.

Closing the thread here, since it's not a Streamlink Twitch GUI issue.

I find how to fix this problem :dancers: :D

In short, we should disable stream title sending to the player (and streamlink). This checkbox is in the GUI options. The problem is in the parameter "--input-title-format"

1. we need the original streamlink-portable.
2. streamlink.bat does not need to be edited, because any change in it prevents us from running anything)
3. Settings -> Panel "Player" -> row "Player window title". Uncheck, checkbox.
4. Apply settings

Done!

how to fix the error in the video format, and what it looks like before and after the error/disable option. https://dl.dropboxusercontent.com/s/kpcfporlmp4tg60/2021-03-10_14-59-15.mp4

In case you're wondering, I realized that all the other parameters, including the title, are sent by options in streamlink.bat and these options go here %*. This is where the error occurs. For the future: there should not be any special characters in the startup parameters.

No, I have already told you what to do to fix the issue properly: https://github.com/streamlink/streamlink-twitch-gui/issues/783#issuecomment-792311331

Don't use the .bat file and instead choose the Streamlink (Python) streaming provider and select the pythonw.exe as python executable and streamlink-script.py as streamlink entry script.

Then you don't need to disable custom player titles, as the issue lies in the streamlink.bat file provided by beardypig/streamlink-portable. The Streamlink (Python) streaming provider executes Streamlink directly via pythonw.exe instead of using a wrapper script/executable (aka. the bat file). Launching Streamlink via the wrapper script/executable is not supported, as you can read in the wiki which I've also already linked.

No, I have already told you what to do to fix the issue properly: #783 (comment)

@bastimeyer I know I read, and took note, but a long time ago (I think since version 1.4.*) launch directly through python script does not work. In my situation (with portable revs etc).

And I'm too lazy to figure out the second time, where and what paths need to change and what Python to download (probably this version is not suitable), etc. I did it in version 1.4, and could not solve anything with this, spending several days to find a solution to the problem.

It's easier for me to uncheck it and use at least somehow the working version, albeit with crutches.

But anyway, thanks for your help. :-* :+1:
