ffmpeg binary not running on M1 Mac [?fixed]

[boisy]

I have a number of SecuritySpy cameras and am using the Cynical SecuritySpy plug-in. I've added them into the plug-in, but when I select the camera in the Home app, it just sits and spins for 5 seconds or so, then gives up.

Run the ffmpeg menu command - this will display ffmpeg logging info.

Have you run the quarantine command? (I would guess so) &

I would disable audio - as some camera streams are incompatible with audio in addition (as per the config dialog)

[Ghawken]

Depending on interest.. can try fine tuning cameras below.

Camera support is a real pain - and I wasted hours and hours. All depends on the ffmpeg settings above.

Can also run the plugin in debugging mode. In the approrpriate terminal window

Can Enter : paste the plugin given ffmpeg given output above Command = ['./ffmpeg/ffmpeg', '-rtsp_transport', 'tcp', '-probesize', '64', '-analyzeduration', '0', '-re', '-i', 'rtsp://boisy:password!!!@imac.local:8000/stream?cameraNum=4&width=1280', '-map', '0:0', '-c:v', 'libx264', '-bf', '0', '-pix_fmt', 'yuv420p', '-color_range', 'mpeg', '-f', 'rawvideo', '-r', '20', '-b:v', '299k', '-bufsize', '2392k', '-maxrate', '299k', '-payload_type', '99', '-ssrc', '5646290', '-f', 'rtp', '-srtp_out_suite', 'AES_CM_128_HMAC_SHA1_80', '-srtp_out_params', 'rN9Dp2awrEL95DURNTPPsAjRmVr8uxI9cvA2+HMS', 'srtp://10.0.0.11:49975?rtcpport=49975&localrtcpport=49975&pkt_size=1316'] subprocess.run(Command)

This will hopefully run ffmpeg as above with output. Enables some settings to be changed… and rechecked.. Looking at these settings - all seems correct (with exception is using imac.local as IP address… presume that should be okay)

[boisy]

Got it. This is very revealing:

[Ghawken]

OK I have seen this - hopefully the dylib exists on your system - just directory is wrong.

If so you create symbolic link for where it is..

Can try

find / -name libX11.6.dylib

(Jay did suggest leaving camera support out until later - because of ffmpeg is an issue. Can install it seperately easily unfortunately….)

[Ghawken]

If someone has a great idea on how to package ffmpeg — or even install it separate to plugin so can be used would be all ears…

(HomeKit bridge packages it like I’m doing, or so I believe. I’m using there version with some additional library support which is needed…)

[boisy]

It's taking a while to find that... in the mean time, I'm using Homebrew to install ffmpeg natively. I'm running an M1 Mac and your ffmpeg binary is x86_64 only. It'll still work with Rosetta 2, I'm sure, but getting ffmpeg built from Homebrew and then copying it over to the plug-in location should fix this. I'll let you know when the build is done.

[Ghawken]

Ok. Double check the Homebrew settings - the ffmpeg build has specific support for libaac which is needed for HomeKit and audio. It’s not included by default (the older aac is supported)

See here:

https://github.com/homebridge/ffmpeg-for-homebridge

Welcome to link to the build (once going!) as should be able to have ffmpeg and ffmpeg-m1 binaries and programmatically select which one to run depending on underlying machine.

[boisy]

It's not working with the Homebrew-built ffmpeg either. Going to take a break from this for a while...

[Ghawken]

This is probably relevant https://github.com/homebridge/ffmpeg-for-homebridge/issues/44

[boisy]

Indeed. Now it's working with the arm64 binary of ffpmeg from that page. Thank you.

[Ghawken]

Thats great news - I’ll see if can add and select which one to run.

[boisy]

Actually you should be able to use the lipo command to merge the two ffmpeg binaries together into one and distribute a single file with arm64 and x86_64 code.

[Ghawken]

Perfect - thanks for the pointers. Have used Lipo to successfully combine ffmpeg and pushed update to version 0.2.23 - hopefully fixing this. Confirm this new binary runs well on x86 system

Please test the M1 mac - the x86 one is working fine on my system It will need the quarantine command run again (everytime updated!)

[boisy]

Yep, it works on my M1! And I verified with lipo that it's a Universal binary (x86_64 and arm64). Good job!

[Ghawken]

That’s great. I did check the ffmpeg as well, with Lipo as well. Was quite straight forward to use

Might close this …
