To fix the x264 installation, I simply added some configure flags. Some files in libavcodec/*.c (in the make output) were reporting undefined references to several functions. I ran into problems with installing the x264 encoding dependency. Any help would be greatly pointed me here: Is there something with my configuration that is malformed? I searched google for this error for some time but never found anything relevant to animations / ffmpeg.

I tried to run a few sample examples I found online:Įverything works fine up until I try to save the animation file. I have confirmed that ffmpeg is installed, although I don't know anything about testing whether it works. I used the chromium source, and installed without a prefix option (using the default). I found this github gist on installing ffmpeg.

I am on a CentOS 7 machine, running python3.7.0a0.

I have covered a lot of ground on stack so far trying to get ffmpeg going so I can make a timelapse video.
