Description

System Information
Operating system: Linux-4.14.78-gentoo-x86_64-AMD_FX-tm-8350_Eight-Core_Processor-with-glibc2.27 64 Bits
Graphics card: NVIDIA GeForce GT 730/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.103.01

Blender Version
Broken: version: 3.2.1 Release Candidate, branch: master, commit date: 2022-06-29 14:18, hash: rB92d1fab5cf3e
Worked: (newest version of Blender that worked as expected)

Short description of error
Blender 2.8 onwards fails to play output video when video player is set to custom with an argument. This works fine with just the application path. Blender 2.7 vesions don't have this problem.

Exact steps for others to reproduce the error
In Preferences > Filepaths set the animation player to custom and put the path to the application for example /usr/bin/mpv --loop. Notice here i have put "--loop" argument. Blender won't play the output video with this path. with just /usr/bin/mpv the video plays. I have attached the screenshots below.

It may be related to this change rB07e5337615e9: Small fix for 'custom' anim player preset (made in Blender 2.68).
Could you check if reverting it fixes the problem?

However it is mentioned that this was a change to fix something (the description could be improved).

How do I revert it? Also the command "/usr/bin/mpv --loop" works fine in 2.7 versions.

I Checked again and it turns out it does not work with 2.76. But on 2.78 and 2.79 it works. And 2.8 onwards it does not.

I don't think this is a bug. The tool-tip of the option clearly states that it expects a path, not a command. Not sure why it worked on those two particular versions.

So the issue reported here is a request for modified/improved behavior and not a bug in current behavior. Closing as this bug tracker is only for bugs and errors.
