ivtv: improve CC support
From: Hans Verkuil <hverkuil@xs4all.nl>
- change the work-queue to a single threaded high prio workqueue
- use DMA instead of PIO for the sliced VBI data.
- remove some incorrect tests
- increase the internal VBI capture queue size for sliced VBI packets
- ignore duplicate VBI lines
With these changes it should finally be possible to get reliable closed
captions.
Priority: high
Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
