gnome-screensav segfault error 4 in libX11.so.6.3.0 #224

Open varac opened 4 years ago

varac commented 4 years ago

I always get such a segfault when using gource, even on a 1-commit test git repo. I use gource like this:

gource /home/varac/oas/testgit -o gource.ppm

and journalctl shows:

kernel: gnome-screensav[9696]: segfault at 211 ip 00007effa0e9cb2d sp 00007ffff6b21ac0 error 4 in libX11.so.6.3.0[7effa0e80000+8b000]

I'm using gource 0.49-1build1 on Ubuntu 19.10 with sway/wayland (maybe this is related to the libX11 segfault) ?

Using the resulting ppm file and transcoding it to webm doesn't work:

❯ ls -alh gource.ppm

❯ ffmpeg -y -r 60 -f image2pipe -vcodec ppm -i gource.ppm -vcodec libvpx -b 10000K gource.webm

It's odd that it says gnome screensaver is segfaulting.

Are you running out of disk space writing the ppm? You could try the one line command to encode a video on the wiki: https://github.com/acaudwell/Gource/wiki/Videos#ffmpeg-using-x264-codec

If you try Gource 0.51 it might possibly help with the 'Invalid data found when processing input' error, as there was an issue with ffmpeg that seemed to be a regression in their handling of ppm files that I tried to work around, however it might actually be a corrupt file in this case.
