Run headless?

[seitzbg]

Is it possible to run this headless and just stream to youtube or file?

This seems to work better but still can't get ffmpeg to accept it:

xvfb-run logstalgia -1280x720 -o - /var/log/nginx/access.log | ffmpeg -y -r 60 -f image2pipe -probesize 5000000 -vcodec ppm -i - -vcodec libx264 -preset ultrafast -pix_fmt yuv420p -crf 1 -threads 0 -bf 0 logstalgia.mp4

Did somebody have any luck with this? I'm also banging my head with it, but even before piping to ffmpeg I receive this error:

$ ssh root@nginx tail -f /var/log/nginx/access_log | xvfb-run logstalgia - -1280x720 -o -

/usr/bin/xvfb-run: line 181: 17615 Aborted                 DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1

Digging a bit more it turns out that xvfb doesn't support the GLX extension so it looks to me this is a dead end. However there are some (older) articles on the web that suggest using xvfb-run in conjunction with logstalgia, so it must be possible. Maybe with an older version or something? I'm using v1.1.2.

I managed to get xvfb-run to work by specifying the display resolution:

xvfb-run -s "-screen 0 1920x1080x24" logstalgia -1920x1080 ...

If you look at the xvfb-run script it defaults to -screen 0 640x480x8 which isn't wouldn't be sufficient.

Same error. Which logstalgia version are you using? Can you give me your fully working command line? Thanks!

[acaudwell]

1.1.2. I don't think the version will matter though. I get the 'GLX is not supported' unless I specify the '-s' option to pass a resolution to xvfb-run.

I had install the package xserver-xorg-video-dummy before hand as I heard that may be necessary but it seemed to also work after removing it. Maybe that installed some dependencies required for GLX to work also?

This produced a working webm for me:

xvfb-run -s '-screen 0 1280x720x24' logstalgia -1280x720 -o - access.log | \
ffmpeg -y -r 60 -f image2pipe -vcodec ppm -i - -vcodec libvpx -b 10000K logstalgia.webm

Thanks for the command line. Still not getting it to work. What is your Linux distribution? I'm using CentOS 7 and the package there was called xorg-x11-drv-dummy, but no luck yet even after installing it. I don't have issues installing another OS just for this.

Just installed a clean Debian 9. Works like a charm. Thanks!
