[pulseaudio-discuss] recording AAC MPEG-4-Audio with gstreamer pulsesrc

[Achim Frase]

I don't know if I am doing something wrong but If I try to record audio
with this gstreamer pipeline the recorded file is broken.

$ gst-launch pulsesrc
device=alsa_output.pci_8086_284b_sound_card_0_alsa_playback_0.monitor !
queue ! audio/x-raw-int,rate=44100,channels=2 ! audioconvert ! faac !
ffmux_mp4 ! filesink location=output.m4a

It would be nice if someone could enlighten me.

Regards
Achim
