Hi All,
When I use ffmpeg to capture video and sound (USB device), I can see the message from alsa-audio-common.c "ALSA buffer xrun." the command line I use : ffmpeg -loglevel debug -f video4linux2 -r 30 -s 640x480 -input_format h264 -i /dev/video1 -f alsa -ar 48000 -ac 2 -i hw:0 -vcodec copy -acodec copy http://localhost:8090/feed1.ffm In record case, it seems ffmpeg get audio slower than usb device capture the sound, such that the buffer overflow, right? Does anyone have idea how to avoid the issue about "ALSA buffer xrun" when ffmpeg capture sound from usb sound card? thanks!
