Stream Google Nest (WebRTC) from homeassistant to youtube

[pertoft]

Hi,

I am trying to stream a google nest cam to a youtube live stream (birdhouse project).
I can see the stream on the go2rtc gui fint (via homeassistant, as its impossible to configure otherwise).

However, Youtube dont detect the published stream. I have tested with an rtsp campera as input and that works.

I guess i need to re-encode the stream to h264 - correct?

hass:
  config: "/home/haas/"

streams:
  cam1:
    - hass://127.0.0.1:8123?entity_id=camera.kamera&token=<redacted>
publish:
    legehus: rtmp://x.rtmp.youtube.com/live2/<redacted>

What I have attempted to reencode:

hass:
  config: "/home/haas/"

streams:
  cam1:
    - hass://127.0.0.1:8123?entity_id=camera.kamera&token=<redacted>
    - "ffmpeg:back#video=h264#audio=aac"
publish:
    legehus: rtmp://x.rtmp.youtube.com/live2/<redacted>

Help wanted :-)

You don't get "stream name" idea.

1. ffmpeg:back#video=h264#audio=aac - transcode stream "back", but you don't have it
2. legehus: rtmp:// - publishing stream "legehus", but you don't have it
3. Transcoding H264 to H264 in same stream - useless. Because clients will always use first (not transcoded) source.

Thanks for the update. I have tried to update the config to reflect the idea:

streams:
  legehus:
    - hass://192.168.1.4:8123?entity_id=camera.kamera&token=<redacted>
    - "ffmpeg:legehus#video=h264#audio=aac"

publish:
    legehus: rtmp://x.rtmp.youtube.com/live2/<redacted>

Have I stream concept understood it correct?

[rtsp @ 0x559ef31e4ec0] Unable to open RTSP for listening

I have managed to run restreamer, consuming the rtsp stream from go2rtc and forward to youtube live, but its very unstable and I hope to get go2rtc working.

Btw, Very nice job!

Unable to open RTSP for listening means you using very outdated ffmpeg version
