Comment (by oviano):

 A workaround is to reload the uvcvideo kernel module:

 $ sudo modprobe -v -r uvcvideo
 $ sudo modprobe -v uvcvideo

 This has to be done each time before running FFmpeg though as the
 underlying problem seems to be the V4L2 or the driver isn't clearing up
 properly after the capture.
