The related issue in Manim and how it was added is documented here: https://github.com/3b1b/manim/issues/335
Thanks for opening the issue. What I can see in the nearer future is the following:
We can directly display the current frame in a window instead of saving it into a file. Then we can use OBS to stream our screen. I know it's dull but at least we would not need to wait to create a gif
or later mp4
but instead could see directly what gets animated.
In general I plan on using an images array instead of saving every frame to an image file as this is what currently slows down Javis.
Hey @freemin7, just following up here, any updates? I saw a post you made in the Julia Slack asking about ffmpeg
regarding streaming:
ffmpeg -re -i input.mkv -c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k \
-bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 \
-ar 44100 -f flv rtmp://live.twitch.tv/app/<stream key>
It might be interesting to have minimal examples like this:
Both demos should work with OBS.
@freemin7 - the latter should be in our documentation. The former idea is being worked on in #345
I know you requested this feature a while ago but I would love to see what animations you should come up with! :)
I didn't find them a new one in https://wikunia.github.io/Javis.jl/dev/examples/#Examples .
https://wikunia.github.io/Javis.jl/dev/workflows/#Live-Streaming shows how to set it up with OBS. However i am unsure how to set up an background as 1:Inf seems dubious.
Hi @freemin7 , it's unfortunately not yet live streaming see #345 The animation is getting rendered before it is sent to obs. As it's sent as a gif such that the animation is just getting repeated.
I would phrase the comment by @TheCedarPrince a bit differently about the interactive demo. It is only possible in the sense that you can change your code and render it again with which it will replace the old animation.
Manim has a
python -m manim --livestream
option and even options for Twitchpython -m manim --livestream --to-twitch --with-key [streamkey]
which allow to write the live rendered content to Twitch in real time.It would be cool to be able to the same from Javis. This functionality might be better suited for a package on top of Javis. As far as i understand ffmpeg provides that functionality.
