go2rtc working fine, but no video in HA due to "Uncaught error from Chrome" / "this.ondata is not a function" errors

[SR-G]

Summary : i'm not able to view any stream from an EZVIZ inside HomeAssistant. However, the URL taken from WebRTC (through WebRTC UI) does work with ffplay. And i have numerous errors in ha log :

WebSocket.<anonymous> (/webrtc/video-rtc.js:338:22)
2024-04-02 23:34:41.868 ERROR (MainThread) [frontend.js.latest.202403070] Uncaught error from Chrome 123.0.0.0 on Linux x86_64
TypeError: this.ondata is not a function

Home Assistant is installed through docker (latest docker image = up to date + fresh install) WebRTC has been installed manually from github release (= 3.5.1)

My card in HA UI is : (password removed) :

type: custom:webrtc-camera
url: rtsp://admin:[email protected]:554/Streaming/Channels/101
muted: true

(note : it's the same with /102 (lower resolution) + this exact same rtsp URL works fine when directly used with ffplay) (also the same with muted line being there or not)

If i go under the :1984 WebRTC page and under "links.html" for that stream, i see this (i suppose) proxified URL :

ffplay -fflags nobuffer -flags low_delay -rtsp_transport tcp "rtsp://<server running HA and webrtc>:8554/rtsp://admin:[email protected]:554/Streaming/channels/102"

And ... this command is working fine ! So i believe that the WebRTC proxy is working. But not the rendering inside CHROME. Due to these "this.ondata is not a function" errors ...

Any ideas ?

Extra notes :

• The camera is a EZVIZ CP1 PRO (with h265 codec + ONVIF since some recent firmware) (of course RTSP has been activated in settings)
• This is also not working with FIREFOX
• however in firefox it seems the stream is "MSE"
• if i force a differernt mode (like webrtc) i have then another error : webrtc/offer: streams not matched: H265, AAC => VP8, RTX, VP9, H264, ULPFEC, RED, OPUS, G722, PCMU, PCMA, TELEPHONE-EVENT, S16B, S16L

Mhh, ok, have just tested on a different computer (this time running Windows 11 and not Archlinux), and on that one (with Vivaldi) :

• webrtc mode gives the same error
• but on that 2nd computer, the mse mode is working !

The non-working station (my main station) is running latest ARCHLINUX / CHROME (version = 123, supposedely with x265 decoding features) (Version 123.0.6312.86 (Official Build) (64-bit), of course with hardware acceleration activated in settings) + a NVIDIA T600 GPU

I don't think I can make a test stand with Arch Linux and Chrome 123. I think some problem with HTML5 MSE for this environment.

Hi I got this error in home Assistant

11:55:24.148 ERR github.com/AlexxIT/go2rtc/internal/mjpeg/init.go:166 > error="streams: wrong login"

It's a camera vacuum

Well. Your camera uses H265 codec. And that answers all your questions: https://github.com/AlexxIT/go2rtc?tab=readme-ov-file#codecs-madness
