Hey Fabricio , yes, If I set the video settings on the capture on the BRIO down to 120P 30fps (640 x 480) and it still crashes. BUT if I set the video size in you VML window settings to 0.5 or 0.25 (320x240) or (160 x 120) it does not crash! live video is working at this size with Face tracking enabled. whilst I do get video working and even when my face goes out of camera it freezes the video but bring my face back in the video restarts fine BUT im not getting any tracking data or face lines overlay like it does with body and hands.. so indeed the smaller size is helping it not crash , but maybe my face (and beard) is too tricky for it to computer perhaps. IU'll try the missus, she doesnt have a beard

UPDATE didnt work with my better halfs face either... BUT I looked at your setup video and it wasnt overlayed on your VML streamer window either! so I did the mocap stream > mediapipe face decoder node setup in houdini and et Voila! works beautifully! with live video. this was 160 x 120 really good and fast update and not too taxing on my RTX 4070 GPU either - just tried 0.5 (320 x 240) refresh is not as quick as 0.25 but its still quick and not too taxing and also works! nice One Fabricio!

Hey! new version tested on windows. Body tracker now works!

I was setting / testing it originally on the one single stream, first load no other streams, on the previous version and I was getting a wierd signal like what Oliver had, but now it works! it takes longer for default first instance video to kick in now, maybe over 10 seconds once Ive selected the web cam, previously it used to be instant. not a problem though actually as setting to 'Direct Show' before selecting the webcam it appears instantly as before.

video window is bigger now though which is good.!

Also I forgot to mention previously that adding the face tracker (again no other streams and first time per instance) previously just closed down the VML Streamer, and it still does the same thing with this version. I see on your demo you used a video file rather than the web cam maybe I should record a video and test as before when I selected video file it crashed also. - aaand just tried on this version. I record a video with my web cam, (MP4) select it with the file browser in the VML streamer then it just closes down the streamer
