plugin crashes homebridge

[jocamero]

As soon as I open the camera in the Home app it causes homebridge to crash with the following error:

[10/12/2016, 12:09:00 PM] Homebridge is running on port 51826. -re -f avfoundation -r 30 -i 0:0 -threads 0 -vcodec libx264 -an -pix_fmt yuv420p -r 30 -f rawvideo -tune zerolatency -vf scale=1280:720 -b:v 299k -bufsize 299k -payload_type 99 -ssrc 1 -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 -srtp_out_params gGoQLRe1wY/rTaou+bKk5I5tCFMNnKfHMv46iqSF srtp://10.0.1.20:65082?rtcpport=65082&localrtcpport=65082&pkt_size=1378 events.js:141 throw er; // Unhandled 'error' event ^

1. Install ffmpeg on your Mac

ENOENT means there is no ffmpeg installed on your Mac.

[jocamero]

Thanks for the quick response!

I just installed it using:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

I'm seeing a static image of my camera in the home app, then homebridge crashes. Do I need to restart or initialize ffmpeg?

[KhaosT]

Are you sure you installed ffmpeg into a path that system is looking for binaries? try to run ffmpeg in terminal and see what it returns.

Use -h to get full help or, even better, run 'man ffmpeg'

[KhaosT]

And if you run which ffmpeg, what's the location it shows?

[jocamero]

/usr/local/bin/ffmpeg

[KhaosT]

The location is right. If you run homebridge now, does it still crash when trying to start streaming?

[jocamero]

Doesn't appear to crash, now I just get a black window for the video stream.

As a sidenote, now there are several new accessories related to iTunes. Other than this plugin, I only have the Nest plugin installed.

[KhaosT]

It should work then. When you start stream on iOS side, what does Home app show? Error?

[jocamero]

Rebuilt homebridge odd iTunes accessories are gone but still getting a black screen. The main page in the Home app shows a static accurate preview, but when opening the live view I see the request in the homebridge log, but nothing appears, just a black screen with a spinning wheel. No errors.

[KhaosT]

I don't know then. Based on the log it should work. You can try to get logs from iOS device and see if mediaserverd is complaining anything but other than that I can't think anything else to fix.

[jocamero]

No worries, thanks for your help!
