[BUG] - ffmpeg exited with code 1

[jcbshw]

FFmpeg errors out when trying to view the stream. I am able to view the stream with the same camera using homebridge-camera-ffmpeg. I compared the how both are starting the stream and the only difference seems to be "-vf scale=1280:720" while using dafang plugin.

Removing "-vf scale=1280:720" from camera.js fixed it

Wonder if it is due to the copy vcodec?

[NoTrace-Kai]

Do you mean this in Line 308?
' -vf scale=' + width + ':' + height +
Thant won't fix my Error 01 Problem with the Camera Stream.
And did you get the Motion Tracker working?

I think the most annoying part of all of this is that everything else is working so well. I got MQTT notifications working 100%, still images show just fine, its just the damn video that I cannot for the life of me get to stream correctly...

Looks like yours is starting the stream with “vfscale” which was causing the issue for me.

Does your camera work with homebridge-camera-ffmpeg?

[billyjacoby]

@jcbshw Last time I tried it with ffmpeg it did.

It worked for about 30 seconds after one time of messing with the configs (didn't do anything really differently) then it just stopped working again.

Do you think this would work better if I ran a different homebridge instance on a Debian or Ubuntu VM, as opposed to running on the rPi?

[jcbshw]

@billyjacoby

I am running it on my RPi 4 using docker-homebride without any issue. If you use the "copy" codec it doesn't encode the video and just transmits it as it to homekit so the RPi is suitable for that. I'd try to get it working in homebridge-camera-ffmpeg first as they have more support with issues, then use those same settings with homebridge-dafang.

I've attached my latest config.json for my camera. I've also removed line 308 from camera.js.

dafang.json

[billyjacoby]

Your config hasn't worked for me either =/

I don't have a user/password setup yet, and I don't think my still image would be available via SSL.

I'm on a rPi 3 as well, im going to spin up a docker version and see if that works..

Edit: I rebooted the camera, and it seems to be working almost flawlessly now! Thanks so much!

[velaar]

@billyjacoby can you please share a working config? I'm trying to figure this one out.

And if possible the video settings on the camera itself (bitrate, resolution, codec, CBR/VBR, etc.)

[mkormendy]

By any chance, is "defang.local" meant to be "dafang.local"?

[DietShasta]

I ran into a very similar problem here. The few takeaways after using camera-ffmpeg and homebridge-dafang.

With camera-ffmpeg, I would always get exited with code 1 when audio was set to true. Changing it to false worked. It may have had to do with my original ffmpeg installation. I don't think I included the aac option.

With homebridge-dafang, I was able to get default video configuration to work after installing the ffmpeg variation with --with-openh264 --with-fdk-aac as stated in the plugin's read me. But when switching vcodec to copy, I would get the exited with code 1 error again. Commenting out -vf scale=' + width + ':' + height + from camera.js is what finally worked as suggested earlier.

I also tried switching from the default still image snapshot that uses the rtsp feed to the jpeg feed by using "stillImageSource": "-i https://CAMERA-IP-ADDRESS/cgi-bin/currentpic.cgi", but this too didn't work for me! You need to add the id:password@ of your camera's web ui (root:ismart12@ when you first set it up) to the address. This is different from the one you set in configuration>video in the camera's web ui. This speeds up the refresh by about 2 seconds..
