Description Daniel Ebdrup Jensen freebsd_committer freebsd_triage 2020-04-06 11:36:53 UTC 
Created attachment 213123 [details]
A patch that adds a message describing how to fix local recording.

Because it seems like obs-studio (specifically, obs-ffmpeg-mux) is expecting /bin/sh to be /bin/bash and uses file descriptors for obs-ffmpeg-mux, "sh: permission denied" can be seen in the log file, and local recording doesn't work.
This patch adds a message for when obs-studio is installed, so that people will know where to fix it so that local recording works on FreeBSD again.

This issue pertains to bug 245299 which seems to have cropped up again, and should hopefully fix it for good.

Could you please add steps to reproduce the problem?

Thanks,

On my system it records in the "Simple" mode without a problem:

With obs-studio-25.0.1 when I click "Start Recording" (with all settings left at out-of-the-box defaults) I get:

and the GUI says "An unspecified error occurred while recording."

obs-studio-25.0.1 is outdated. Could you please try it with the current obs-studio-25.0.4?

Thanks,
Yuri
Comment 5 Yuri Victorovich freebsd_committer freebsd_triage 2020-04-06 18:39:16 UTC 
Need feedback: confirmation that the failure occurs with the version 25.0.4

If the problem exists in 25.0.4, please also attach the kernel syscall log fragment showing the failing system call. I can't reproduce the failure on my system.

I've tested with 25.0.4, it works fine.
The issue was fixed by bug245299 and bug245403.
