[FEATURE] 0.8.0 Cameras with a "copy" codec and video filter "none" do not work

[cacherocks]

The best video quality in cameras through HomeBridge is achieved by choosing:

• vcodec: copy
• videoFilter: none
• additionalCommandline: -crf 12 (numerical value may vary)

If, I specify the same parameters in NRCHKB 0.8.0, then the cameras do not work:

If the logic of operation of the Camera accessory is similar to the logic in Homebridge, then in theory everything should work because the settings are saved exactly the same.

What plugin do you use on Homebridge to enable cameras?

What plugin do you use on Homebridge to enable cameras?

homebridge-camera-ffmpeg

I have an idea. Enable debug in homebridge-camera-ffmpeg and look what command is executed, there should be line 'ffmpeg ' + command And do the same at nrchkb, enable debug in Camera config and restart node-red and look what command is executed.

Paste both below and we will se why and what is the difference.

• additionalCommandline: -crf 12 (numerical value may vary)

Bad idea. Copy means exactly the same video stream, so just skip crf and VideoFilter. Don't tested this, but have a big experience with HB )

@cacherocks check latest dev branch, there is additional check for videoFilter and possibility to add Interface Name.

[cacherocks]

A little busy days, I only managed to test the work on the # dev branch and the cameras still did not work. In the coming days I will post a debug from HB & NR.

In the meantime, questions,

• Does the Video Filter field understand the parameter none?
• Is it possible to make an Additional Command Line an optional field?

[Shaquu]

In newest dev Video Filter filters out none value just like in homebridge. If there is a reason to make Additional Command Line optional then yes, I can make it optional.

[cacherocks]

@Shaquu In the dev branch, the cameras completely stopped working, they immediately write in the Home application "This camera does not respond", and in the NodeRed this error is being poured:

If thoughts on this?

[Shaquu]

Well I would prefer logs from terminal and not those from node-red ui :) It looks like the bridge is empty. Can you share your flow which is causing this error? When it appears? On start? On deploy? On message input or output?

[cacherocks]

Well I would prefer logs from terminal and not those from node-red ui :)

I would send a log from the terminal if it was =) There is no log from cameras in the terminal on the dev branch. On version 0.8.0, it simply gave status "FFMPEG exited with Error code 1" and there was no “TypeError" in the error.

@cacherocks please check latest dev I imported your flow and it works for me.

[cacherocks]

1. To fix the error, it was required to recreate the nodes on the dev branch, that is, the error occurs with the nodes when updating from 0.8.0 to dev
2. Cameras with the "vcodec": "copy" earned! Thank you! 🥳

[Shaquu]

I would rather step 1 to work without recreating. Please recheck if you have original flow from version 0.8.0

Either way, decide if and when we can close the issue.

[cacherocks]

I didn’t have a flow with errors, I fixed them right away. In any case, many thanks for the work done, I'm almost ready to remove the homebridge (there was only a TV for which I couldn’t get the remote control and volume control in the nodered) =)

[Shaquu]

@cacherocks well I will do everything to convince you that NRCHKB is enough for you;) Remote Control should work, about volume controls it needs tests.
