Record canvas in posthog

Context: https://posthog.com/questions/canvas-recording-not-working

From Vincent: You would need a custom aframe build to test that. preserveDrawingBuffer is an option for WebGLRenderer, you can add it here https://github.com/aframevr/aframe/blob/ca7b02ddd7bfa9d606cbbe7b092eb0c08afe5728/src/core/scene/a-scene.js#L618

• download aframe 1.5 tag
• modify the build under context preserve drawing buffer (see Vincent's link above)
• build it and try it?

will monkeypatch like raytracing work?

• no, that was just for the render function, not the creation of the webgl renderer

[vincentfretin]

If that works, add a preserveDrawingBuffer property to aframe renderer attribute and create a PR upstream aframevr/aframe#3750

should we do this by forking a-frame repo? I'm eager to get this fixed

[vincentfretin]

Yes fork it, create a branch, make a quick change, create a build and copy it locally to 3dstreet repo and reference it in index.html
If that works, make a PR to a aframe with a better change adding an option to the renderer so that we don't leave forever with a fork.

hmm i dont think it worked. Tried it in https://github.com/rahulkgupta/aframe/tree/preservedrawingbuffer

1. updated src/core/scene/a-scene.js
2. ran npm build dist
3. copied aframe-master.min.js to 3dstreet repo
4. referenced it in webpack config. try locally built aframe #871

I don't see any commit in your branch, can you push the change you made?

[rahulkgupta]

updated, https://github.com/aframevr/aframe/compare/master...rahulkgupta:aframe:preservedrawingbuffer?expand=1

[vincentfretin]

Thanks.
Did you deployed to staging environment? Do you have posthog for the staging environment to see one of the video capture? It's still black?
I don't think we have sessions send to posthog for local environment, right?

[rahulkgupta]

i updated posthog to capture local development. speaking of which, i should probably turn that off now
