Webcam initalization assumption about mediapipe-touchdesigner

[domisjustanumber]

Hey @joreg thanks for taking the time to dig into this. Getting webcams to reliably start and return data has been something I've been tinkering with for a while, and this is a new way of it breaking that I haven't seen before!

That's a good idea on how to catch it - I can move the webcam started detection into the prediction loop - then if the webcam takes a while to start, there are more chances to catch it later.

If you want to make the change, feel free to submit a PR for it and/or I'll be doing some work on this project over the holidays so can put the change in then.

so here is how i fixed it on our end for now: vvvv/VL.MediaPipe@0b56dff?diff=unified&w=1

not sure if this is the best way, but it seems to work so far.

Oh amazing, thank you!

I'm also having web cam issues when running it. Seems like the camera its trying to use doesn't default to the correct resolution. But I'm not sure how I can set that in the MediaPipe container. And the image segmentation container is supposed to take the same cam input? I did come up with a workaround using NDI in/out.

Hey @joreg I rolled some of the suggested changes you made into the latest release, so hopefully the webcam loads more reliably and faster now. Thanks for the tip and you're welcome to copy any changes to your vvvv implementation!

@deseipel this release should also (hopefully) fix your webcam startup/resolution issue https://github.com/torinmb/mediapipe-touchdesigner/releases/tag/v0.4.1
