Comment(by lfarkas at math.bme.hu):
The problem is that my device cannot be opened twice. For example:
cat /dev/v4l/video1 > something1.mpg
works, but
cat /dev/v4l/video1 > something2.mpg
gives
error: Device or resource busy
If I patch the the libmythtv/mpegrecorder.cpp file to
close(chanfd)
before the command
open(readfd ...
then the device can be opened, but the channel cannot be set in LiveTV.
