So is the documentation for the SAA6752 available?
All the needed documentation to control this IC can be found in the
datasheet on the Philips Semiconductors website:
http://www.semiconductors.philips.com/pip/SAA6752HS.html
Or is there ane open source driver in the works?
I'm not aware there is a "real" driver available. But, the only thing
this driver should do is boot the IC and initialise the encoder with the
wanted settings. Currently I do this with a user space program via the
I2C user space device. But actually this should be part of the driver,
through an V4L2 API extension for MPEG encoder settings.
