Permission denied in Video recording

[Andrea]

Hello team,

I cannot record a video of my GUI (with V shortcut). I get the following message when trying to do so:

[INFO]    [VideoRecorderFFMPEG] Start recording to /home/andrea/projects/sofa/build/install/screenshots/caduceus__r60_0001.mp4 ( yuv420p, 60 FPS, 5120000 b/s) using /home/andrea/projects/sofa/build/bin/
sh: 1: /home/andrea/projects/sofa/build/bin/: Permission denied

I am on v20.12 of Sofa and I use a QGLViewer.
My SOFA_ROOT is set to sofa/build/install

Thanks
Andrea

Hi @amendiza

This means your runSofa executable is run without write privileges. Could you try a:

sudo chmod 777 runSofa

Best wishes,

Hugo

Hi Hugo,

Thanks for your answer.

I also thought this was the reason, but it is not. The error is still there after adding all the privileges to runSofa…

Ok …
Either the ffmpeg which has wrong rights, or the repository in which you are trying to write (build/bin) have strange rights.

Is there a ffmpeg in build/bin ? if so what are its rights ? is it executable ?

Maybe @tgaugry has an idea ?

Best,

Hugo

Dear Hugo,

There is no ffmpeg in my build/bin… What is the clean way for having it?

Thanks

Andrea

It can also be the rights on the output folder or file, or more simply on a temp folder. Another reason could be that the output folder does not exist (some functions misattribute this error sometime, dunno why).

In any case, you can to rexec with sudo, this should tell us if it really is a permission problem, or if it is something else.
