There is a lot of documentation for using gphoto2 to use a DSRL as a webcam. With those techniques, the system sees the camera as a new video device
gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video0
or
gphoto2 --stdout --capture-movie | gst-launch-1.0 fdsrc fd=0 ! decodebin name=dec ! queue ! videoconvert ! tee ! v4l2sink device=/dev/video0
But what about sound? Is there a way to plug the DSLR microphone to my system so I can use the camera audio too? It seems that gphoto2 as a --capture-sound parameter, so it seems it is ready for that, but then what? How to plug ffmpeg or gst-launch so they can use the audio?
