Display camera ip in dashboard and store video in raspberry

I am not sure about those npm warnings, as my node does not use them as a dependency

we will leave aside then since it works like that.

@kevinGodell

For the ffmpeg command line, I have much to say, but it depends on your situation.

@kevinGodell

for video playback, motion detection, etc, to make a fairly complete cctv system running on node-red.

that's exactly what I would like (and probably many more). Here is an example of my dashboard:

it is a global view of all the sensors in the house (water heater, swimming pool, etc.)

On the left we see that a person has been detected at the portal.object detection project here
And on the right the streaming of the portal camera. (the cameras are under tabs that you can unfold and automatically launch the rtsp stream).

Fortunately, I chose the camera stream = 1 to reduce the processor load. For example if I run 4 cameras at the same time I have 25% cpu load (RPI 3b)

If I click on the camera, I switch to stream = 0 (1080p) on a full page (all other streams are stopped), the cpu is at 40%

@kevinGodell

,scale=iw/2:-1

Not bad : Makes me go from 40% to 25% cpu while losing a bit in quality (960x540px).

@kevinGodell

If your system supports hwaccel ( ffmpeg -hwaccels ), I would take advantage of that for GPU decoding of mp4 (rtsp) so that the CPU can encode the jpeg

I failed to get it to work by adding it in my current command line:

• the pipe2jpeg node announces : "pipe2jpeg: input must be a buffer"
• if I remove pipe2jpeg : "unrecognized image format"

@kevinGodell

A better solution would be to stream copy the h264 video from rtsp to mp4 and play it in a mediasource extension video player (without writing files to the disk).

Are you thinking of doing it? It would be a terrible step forward.
