FORCE_FPS doesn't appear to be working

[jarrah31]

Hello,

I have Wyze-bridge 2.8.1 running as a Docker container. It connects to the following three Wyze cams:

Wyze Cam v3 - v4.36.11.8391
Wyze Cam v3 Pro - v4.58.11.8391
Wyze Cam Pan v3 - v4.50.4.9222

In my Docker environment variables I have the following set:

    environment:
      # [REQUIRED] Fill the following two lines:
      - WYZE_EMAIL=$WYZE_EMAIL
      - WYZE_PASSWORD=$WYZE_PASSWORD
      - RTSP_PATHS_ALL_READUSER=$WYZE_RTSP_USER
      - RTSP_PATHS_ALL_READPASS=$WYZE_RTSP_PASS
      - FORCE_FPS_FRONTCAMTOP=10
      - FORCE_FPS_GARAGECAM=10
      - FORCE_FPS_KITCHENCAMPAN=10
      - TOTP_KEY=$WYZE_TOTP
      - NET_MODE=LAN
      - ENABLE_AUDIO_GARAGECAM=True
      - MQTT_HOST=${MQTT_HOST}
      - MQTT_AUTH=${MQTTAUTH}
      - MQTT_TOPIC=wyzebridge
      - MQTT_DTOPIC=homeassistant
      # - FRESH_DATA=true
      # - AUDIO_CODEC=AAC
      - WB_IP=${DOCKER_HOST_IP}
      - DEBUG_FFMPEG=true

I use the RTSP streams to feed into SecuritySpy which is reporting 20fps for all three cameras.

Looking at the docker logs, on startup it says the following:

As you can see here it tries for force 10fps, however when I look at the Wyze-Bridge web GUI and select the 'I' icon on each camera, it says fps = 20:

videoParm	{ "bitRate": "30", "fps": "20", "horizontalFlip": "1", "logo": "2", "resolution": "2", "time": "1", "type": "H264", "verticalFlip": "1" }

This is also backed up in the SecuritySpy app:

Trying other versions seems to work better:

v2.6.0 is close to 10fps

v2.7.0 does 20fps with one of the cams

The main reason for reporting this is because it helps reduce my wifi bandwidth, especially for the Pan Cam because that is further away from the router. (or does it? I guess the camera always sends 20fps and wyze bridge just re-encodes as 10fps?)

hmm I'll have to look into this.

[jarrah31]

Thank you, hopefully it’s not just me seeing this difference.

[mrlt8]

Could you try the latest dev build to see if that helps?

I noticed that FPS was a little sticky on some cameras, and I needed to reboot the camera via the webUI for the FPS to updates sometimes.

[jarrah31]

Thanks for the update, I should be able to try this on Monday when back home.

[mrlt8]

@jarrah31 could you try the dev branch to see if that helps?

[jarrah31]

Very sorry @mrlt8 it's been a busy week at work and I clean forgot to test the dev branch. I've now just installed 2.9.0 and can confirm FORCE_FPS now works great. Thank you very much!

[jdeath]

how set force_fps in home assistant mode (using latest dev container)? Tried
FORCE_FPS_KITCHENCAMPAN: 10
and
FORCE_FPS:10 under cam_options

neither seems to work (do not see it trying to request lower fps in log).

I am trying to reduce memory usage. High usage of the bridge appears to crash my system.

[mrlt8]

hmm, I think we're missing the fps options for HA. will have to look into that!

edit: in the meantime, you should be able to use the api or MQTT to change the FPS manually.

2.9.2 works great for fps in HA. Lowered my memory usage by using 5fps. Hopefully no more crashes.
