Specify alsa device name or aloop for system ouput audio to be used as input in ffmpeg command
0
I am using Debian 9 with its version of ffmpeg. This is my ffmpeg command I use to screen record:
ffmpeg -thread_queue_size 4096 -f alsa -i plughw:CARD=Device,DEV=0 -thread_queue_size 4096
-f alsa -i default -filter_complex amix=inputs=2:duration=first -thread_queue_size 4096
-f x11grab -r 30 -s 1920x1080 -i $DISPLAY+1920,0 -c:v libx264 -crf 20 -preset veryfast
-c:a aac -ac 2 -b:a 96k -pix_fmt yuv420p -movflags faststart output.mp4
I am able to successfully record my system sounds and microphone at the same time. However, I first need to open pavucontrol and make sure the system audio is set to default on the Input Devices tab. I would like to be able to use the specific device name for system sounds as I do for my microphone with plughw:CARD=Device,DEV=0. However, I am not sure what should be used. For system sounds, using -f pulse -i alsa_output.pci-0000_00_14.2.analog-stereo.monitor works, but there is about a 15 second delay in the recorded video file. So, I would need to use -f alsa -i $device_name.

I have also tried using -f alsa -i loopout as mentioned here. I first enabled the ALSA aloop kernel module with: insmod /lib/modules/4.9.0-8-amd64/kernel/sound/drivers/snd-aloop.ko. It loaded properly:
~$ lsmod | grep aloop
snd_aloop 24576 6
snd_pcm 110592 10 snd_hda_intel,snd_hda_codec,snd_usb_audio,snd_hda_core,snd_hda_codec_hdmi,snd_aloop
snd 86016 35 snd_hda_intel,snd_hwdep,snd_hda_codec,snd_usb_audio,snd_timer,snd_rawmidi,snd_hda_codec_hdmi,snd_hda_codec_generic,snd_usbmidi_lib,snd_seq_device,snd_aloop,snd_hda_codec_realtek,snd_pcm
However, I received an error when trying to record with ffmpeg:[alsa @ 0x55bd6922ee40] cannot open audio device loopout (No such file or directory).
loopout: Input/output error
Using the loopout (or perhaps it is loopback?) might be most ideal because it is my understanding that this would capture any system sound no matter the hardware device.
So, to summarize I would like to be able to use ALSA to capture any system output sounds during screen capture, no matter which card or device is default at the time.
Much thanks in advance.

I have also tried using -f alsa -i loopout as mentioned here. I first enabled the ALSA aloop kernel module with: insmod /lib/modules/4.9.0-8-amd64/kernel/sound/drivers/snd-aloop.ko. It loaded properly:
~$ lsmod | grep aloop
snd_aloop 24576 6
snd_pcm 110592 10 snd_hda_intel,snd_hda_codec,snd_usb_audio,snd_hda_core,snd_hda_codec_hdmi,snd_aloop
snd 86016 35 snd_hda_intel,snd_hwdep,snd_hda_codec,snd_usb_audio,snd_timer,snd_rawmidi,snd_hda_codec_hdmi,snd_hda_codec_generic,snd_usbmidi_lib,snd_seq_device,snd_aloop,snd_hda_codec_realtek,snd_pcm
However, I received an error when trying to record with ffmpeg:[alsa @ 0x55bd6922ee40] cannot open audio device loopout (No such file or directory).
loopout: Input/output error
Using the loopout (or perhaps it is loopback?) might be most ideal because it is my understanding that this would capture any system sound no matter the hardware device.
So, to summarize I would like to be able to use ALSA to capture any system output sounds during screen capture, no matter which card or device is default at the time.
Much thanks in advance.

I am using Debian 9 with its version of ffmpeg. This is my ffmpeg command I use to screen record:
ffmpeg -thread_queue_size 4096 -f alsa -i plughw:CARD=Device,DEV=0 -thread_queue_size 4096
-f alsa -i default -filter_complex amix=inputs=2:duration=first -thread_queue_size 4096
-f x11grab -r 30 -s 1920x1080 -i $DISPLAY+1920,0 -c:v libx264 -crf 20 -preset veryfast
-c:a aac -ac 2 -b:a 96k -pix_fmt yuv420p -movflags faststart output.mp4
I am able to successfully record my system sounds and microphone at the same time. However, I first need to open pavucontrol and make sure the system audio is set to default on the Input Devices tab. I would like to be able to use the specific device name for system sounds as I do for my microphone with plughw:CARD=Device,DEV=0. However, I am not sure what should be used. For system sounds, using -f pulse -i alsa_output.pci-0000_00_14.2.analog-stereo.monitor works, but there is about a 15 second delay in the recorded video file. So, I would need to use -f alsa -i $device_name.
