| I used to do some basic CV stuff back when I did the First Robotics Competition (FRC) in high school, so it's cool to see it being done over WebRTC! |

| ▲ | Sean-Der 3 days ago | parent [-] | | Hey good to see you, we gotta get your PR merged and on here also :) It's really cool how you can have a heavy server doing all this cool computer vision stuff, but then a simple client that just does WebRTC. If you adjusted the example you can quickly be sending OBS or ffmpeg in. Then that gets really cool/powerful | | |
| ▲ | valorzard 3 days ago | parent [-] | | Yeah the PR is pretty much "done" at this point
(there's more stuff I could probably do but perfect is the enemy of good) |

| For anyone curious, this line of comment shows how it's done: > startCameraAndStream opens the webcam with GoCV, sends raw frames to FFmpeg (via stdin), reads IVF from FFmpeg (via stdout), and writes them into the WebRTC video track. |

* GStreamer
* Use libvpx, examples is in mediadevices repo |

| Neat demo — cool to see GoCV + Pion working together over WebRTC. Curious if you’ve tried running object detection or overlays before sending the stream? |
| |
| ▲ | Sean-Der 3 days ago | parent [-] | | I did! I tried integrating with a couple different of the examples on here [0] The good detection ones required users to download something first, so I was worried the friction would make people less likely to use them. The one I almost went with was hand-gestures, but it wasn't as reliable. I haven't used opencv that much. I see people talk about in Pion discord (and examples like this) and gets me into. I think someone more proficient could build a more compelling demo pretty quickly :) [0] https://gocv.io/writing-code/more-examples/ |

| Huh, wonder if go2rtc could use this to make HKSV cameras work. |
