8 DVB Video Device
14 The DVB video device controls the MPEG2 video decoder of the DVB
17 ``linux/dvb/video.h`` in your application.
19 Note that the DVB video device only controls decoding of the MPEG video
22 ``/dev/video``, which allows scaling and defining output windows.
24 Most DVB cards don’t have their own MPEG decoder, which results in the
25 omission of the audio and video device as well as the video4linux
31 functionality. Use :ref:`V4L2 ioctls<video>` for new drivers!
