Hello! I am trying to capture audio from an ATI Wonder 600 USB adapter using
ffmpeg -f alsa -ac 2 -ar 48000 -i hw:1,0 -t 10 a.wav but I receive the error [alsa @ 0x555d7c2850a0] cannot set ALSA buffer size (Invalid argument) hw:1,0: Input/output error using - ffmpeg version 3.3.4-2+b3 - alsa k4.13.0-1-amd64 - linux 4.13.0-1-amd64 Note that `arecord -l` gives: card 0: PCH [HDA Intel PCH], device 0: ALC1220 Analog [ALC1220 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 2: ALC1220 Alt Analog [ALC1220 Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Em28xxAudio [Em28xx Audio], device 0: Em28xx Audio [Empia 28xx Capture] Subdevices: 1/1 Subdevice #0: subdevice #0 and I can capture audio/video without problems using the `qv4l2` test bench. Thanks!
