This happens everytime I start a new record, just after the countdown from 3 to 0 finished.

What version of ffmpeg is this and how did you install it? It looks like it was built without x11grab / xcb support. If you built ffmpeg from source please try compiling it with --enable-libxcb. Maybe you even have to specify --enable-libxcb

[phw]

Closing, no user feedback. But compiling ffmpeg with xcb support should fix this.

Hi, I've ffmpeg compiled with xcb support, but recording fails (was working before)

worker /home/marian # emerge -av ffmpeg

These are the packages that would be merged, in order:

[Jieiku]

I am wondering if Peek could do a little error handling here and check that the lossless option is available, and use a different mode if it is not. I am not too horribly concerned about quality. I just want to make a simple gif recording that I can submit with bug reports.

[anastasiadubrovina]

Re-opening this thread: @phw I used standard sudo apt-get ... to install both keep and ffmpeg, and get the same error. Do you have some instructions for installing ffmpeg with xcb? Alternatively, to make Peek to actually work "out of the box" - could it include the necessary pre-built ffmpeg? Thanks!
