Hi, I'd really like to see some support for RDS/RBDS in v4l2; there is a flag V4L2_CAP_RDS_CAPTURE, but AFAIK right now nothing uses it.
For a private program there is no problem with e.g. using /dev/i2c-x to read out the SAA6588 registers (the Terratec Cingery 600 uses this RDS/RBDS decoder chip), but if you plan to integrate RDS support in a more general way into programs like "kradio", it's a no go. On the Terratec card, the oscillator needs to be initialised to a non default value (it uses a 8.664 MHz crystal), and IMO this initialisation belongs into the driver, as it is card specific. Furthermore, I don't know what other chips or means of obtaining a RDS signal are used with other cards (maybe there are cards around where error correction must be done in software?), so ideally one would open a device /dev/v4l/rds and obtain an RDS "stream" from there. My question: I'm wondering how and where RDS support can be added to v4l2? For the SAA7134 driver, would it make sense to add another flag to "struct saa7134_board"?
