I set up a fresh PatchboxOS, and I’m running a PureData patch that generates audio. Everything seems fine, it’s playing audio out of the headphone jack no problem.
I’ve compiled ffmpeg from source
Listing my sources returns the following:
$ ffmpeg -sources alsa Auto-detected sources for alsa: * default [Playback/recording through the PulseAudio sound server] null [Discard all samples (playback) or generate zero samples (capture)] jack [JACK Audio Connection Kit] pulse [PulseAudio Sound Server] usbstream:CARD=ALSA [USB Stream Output]
My ffmpeg script for good measure:
ffmpeg \ -re \ -f alsa \ -i default \ -stream_loop -1 \ -re \ -i loop.mp4 \ -shortest \ -ar 44100 \ -c:v copy \ -c:a aac \ -f flv "$URL"
This all works fine, except no audio. I’ve tried every permutation that I can think of, but I must not be understanding something.
- Does anything else need to be pre-configured? Patchage?
- Pd: Media > ALSA logs
ALSA input error (snd_pcm_open): No such file or directory
-f alsa -i defaultcorrect?
Any pointers would be huge, thank you!
