Write to GIF? about asciinema-player HOT 7 CLOSED

If you append .gif to your recording URL now you get instructions on how to generate gif animation for it. Example: https://asciinema.org/a/113463.gif

I think the best way to implement this would be to use player's VT (https://github.com/asciinema/asciinema-player/blob/master/src/asciinema/player/vt.cljc) and its view (https://github.com/asciinema/asciinema-player/blob/master/src/asciinema/player/view.cljs), and the PhantomJS script similar (but more complex) to the one currently used for generating .png screenshot (https://github.com/asciinema/asciinema.org/blob/master/bin/rasterize).

This would give the best quality (the same as we have for .png on asciinema.org now), and would produce .gif with variable frame times (constant frame rate is unnecessary in our case and would produce bigger files and/or took longer time - this is what https://github.com/tav/asciinema2gif does right now).

Please try out https://github.com/asciinema/a2gif (I implemented the idea from #24 (comment)).

I can't test this ability right now, but I will certainly do when I find the time. Thanks!

I'm seeing a failure from the docker instructions provided by that .gif link:

docker run --rm -v $PWD:/data asciinema/asciicast2gif https://asciinema.org/a/tw4lOrVzXMcxdBeOnHBIOvvL8.cast demo.gif

This issue still seems relevant?
