The TS capture is working very good for the EMPRESS board.
This board is actually a very experimental PCI board with a SAA7134 and
an the SAA6752 MPEG-2 encoder:
http://www.semiconductors.philips.com/pip/saa6752hs/v101
The encoder is currently initialised via the userspace I2C device and
then it continously
streams an MPEG-2 TS to the SAA7134. The resulting MPEG-2 Transport
Stream data can be read
from the 2nd video device of the SAA7134 driver: e.g. "cat /dev/video1 |
mpeg2dec -t 100"
The TS capture code could also easily be used for other boards, e.g.
boards with a
combined analog/digital TV tuner. It might need to initialise the DVB
demodulation ICs.
And perhaps the TS interface needs to be initialised in a different way.
