Performance issue on 6 cameras

[guocity]

Try to troubleshoot for performance for 6 cameras, [docker-wyze-bridge] v2.3.13 wyze bridge video view is acceptable, but homekit video is unusable, rule out cpu, memory, network bottleneck, where can i find performance issue?

Probably a network issue. The wyze cams tend to flood the wifi which can cause issues. IGMP and multicast related configs may need to be adjusted on your AP/router.

👍, i added 6 cameras to raspberry pi4, my cpu usage is at 50% is the following code going to make wyze-bridge use less cpu?

devices: - /dev:/dev environment: - ROTATE_DOOR=True - H264_ENC=h264_v4l2m2m

[mrlt8]

It should help with re-encoding for the doorbell. may need to manually specify the devices on the pi:

        devices:
            - /dev/video10:/dev/video10
            - /dev/video11:/dev/video11
            - /dev/video12:/dev/video12

interesting, what are the video for?

I believe 10 11 and 12 are used for h264_v4l2m2m. Not sure about the others.

[guocity]

Thanks, load reduce from 60% to 40%

[guocity]

I still have performance issue, with 40% cpu usage is anyway to optimize it?

[mrlt8]

Reduce the number of snapshots? Taking a snapshot requires the h264 to be decoded which can result in a CPU spike. We could try offloading that to the hardware decoder, but I'm not sure how much of a difference that might make. Will try to look into it.

[guocity]

@mrlt8 I want to try to use m1 mac, it perform much faster in scrypted, do you know there is any setting that i can do hardware decode h264 in macos? cpu usage is really high

[mrlt8]

I don't believe it's possible to access VideoToolbox via docker. Might be able to do the decoding in scrypted since it runs directly in macOS?
