No audio: unknown encoder 'libfdk_aac'
Closed this issue · 2 comments

Describe The Problem:
Using this plugin to pass a local video stream to homekit. Video stream and snapshot work without audio. When "Enable Audio" selected the video stream no longer works (and no audio). Logs below show the error: unknown encoder 'libfdk_aac'. Audio confirmed working using VLC player with local feed. FFmpeg shows libfdk_aac as a supported encoder. There were a few similar issues posted in the past, but I could not find any resolutions.
Does an option need to be enabled for this specific encoder? I cannot find any audio preferences to adjust.
To Reproduce:
Enable audio with the below config.

Sounds like you probably didn’t end up with ffmpeg-for-homebridge somehow. I know sometimes reinstalling the plugin has fixed that.

That worked! Thank you and awesome project!
