Hi, new here
Just a thought - it’d be really cool if ffmpeg supported asciinema recordings. Easiest integration option would probably be to convert them to a subtitle format, then they can be rendered into/over video.
I haven’t looked at this in depth, but a more advanced option: make a “render buffer” type thing where actions can accumulate in a virtual tty, and have both diffs and key-frame snapshots. This would be useful in general, for when you accidentally drop 100MB of logs into your recording and want to reduce the file size by limiting the frame rate. Then implement the same filters that ffmpeg supports for video, but applied to the text buffers. Expose it with the same API as its video plugins, and a way to convert to pixel data (might need font and size in the header, with sensible defaults), and offer it up as a video option.
