Describe the bug
I installed OpenScreen 2.1.1 on Ubuntu 24.04. When I select the screen and start recording, the application crashes with this error:
The Linux capture helper exited (code=null, signal=SIGSEGV)
The crash report shows a segmentation fault inside OpenScreen's bundled FFmpeg library (libavcodec.so.62) while opening a video codec (avcodec_open2).
My system has AMD Radeon graphics. VA-API is available and reports H.264 encoding support.
Could you help identify the cause and advise how to fix this?
Thank you.

Thanks for the report. The
libavcodeccrash inavcodec_open2is a lead, but your report says both Ubuntu 24.04 and 22.04: which one is it? Could you also send the Mesa version, the output ofvainfo, the lines of the terminal output containingcapture-linuxafter the crash, and a Save Diagnostics file if the app still opens? That tells us which encoder it tried to open.
