cx8800 release notes ==================== This is a v4l2 device driver for the cx2388x chip. current status ============== video - Basically works. - For now, only capture and read(). Overlay isn't supported. audio - The chip specs for the on-chip TV sound decoder are next to useless :-/ - Neverless the builtin TV sound decoder starts working now, at least for some standards. FOR ANY REPORTS ON THIS PLEASE MENTION THE TV NORM YOU ARE USING. - Most tuner chips do provide mono sound, which may or may not be useable depending on the board design. With the Hauppauge cards it works, so there is mono sound available as fallback. - audio data dma (i.e. recording without loopback cable to the sound card) is supported via cx88-alsa. vbi - Code present. Works for NTSC closed caption. PAL and other TV norms may or may not work. how to add support for new cards ================================ The driver needs some config info for the TV cards. This stuff is in cx88-cards.c. If the driver doesn't work well you likely need a new entry for your card in that file. Check the kernel log (using dmesg) to see whenever the driver knows your card or not. There is a line like this one: cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \ 34xxx models [card=1,autodetected] If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to the driver. What to do then? (1) Try upgrading to the latest snapshot, maybe it has been added meanwhile. (2) You can try to create a new entry yourself, have a look at cx88-cards.c. If that worked, mail me your changes as unified diff ("diff -u"). (3) Or you can mail me the config information. I need at least the following informations to add the card: * the PCI Subsystem ID ("0070:3400" from the line above, "lspci -v" output is fine too). * the tuner type used by the card. You can try to find one by trial-and-error using the tuner=<n> insmod option. If you know which one the card has you can also have a look at the list in CARDLIST.tuner Have fun, Gerd -- Gerd Knorr <kraxel@bytesex.org> [SuSE Labs]
