I had this working using Sean’s original tutorial but I found the video feed froze and stuttered a lot. I’m not sure if it was because in order to use https I had to use the external url which was then sending the feed to the web and streaming it from there. But in a 15s popup there would only be about 3-4s of actual video and the rest was freezing and stuttering.
I switched to using frigate’s MJPEG stream as described in this post. I’m using the apk linked above, http and an internal ip address.
Now my video stream is very smooth with minimal lag
