  7. Troubleshooting attempts you’ve made?
    I’ve tried to set up hardware decoding instead of MJPEG via HLS and was told it’s unsupported in the new builds because they removed H264 OMX encoder for H264 M2M, tried changing picture quality, resolution, etc. Slight uptick in speed at lower resolutions and quality but still not getting the advertised speeds.

  8. What help do you need?
    I just want to get the IMX519 to take photos and videos at the speed advertised within OctoPi. That’s it, that’s all.

Sadly, like you said, MJPEG encoding is currently a software encoding, so its speed may not be ideal. But I tested it on Pi4, although the CPU usage is relatively high, it should be able to reach [email protected] (I used libcamera-vid+gstreamer for testing)

So what do I do if I only have a Pi 3B+ and am trying to get the correct FPS within an OctoPrint install? Is there a guide for setting this alternative up?
