1cx8800 release notes 2==================== 3 4This is a v4l2 device driver for the cx2388x chip. 5 6 7current status 8============== 9 10video 11 - Basically works. 12 - For now, only capture and read(). Overlay isn't supported. 13 14audio 15 - The chip specs for the on-chip TV sound decoder are next 16 to useless :-/ 17 - Neverless the builtin TV sound decoder starts working now, 18 at least for some standards. 19 FOR ANY REPORTS ON THIS PLEASE MENTION THE TV NORM YOU ARE 20 USING. 21 - Most tuner chips do provide mono sound, which may or may not 22 be useable depending on the board design. With the Hauppauge 23 cards it works, so there is mono sound available as fallback. 24 - audio data dma (i.e. recording without loopback cable to the 25 sound card) is supported via cx88-alsa. 26 27vbi 28 - Code present. Works for NTSC closed caption. PAL and other 29 TV norms may or may not work. 30 31 32how to add support for new cards 33================================ 34 35The driver needs some config info for the TV cards. This stuff is in 36cx88-cards.c. If the driver doesn't work well you likely need a new 37entry for your card in that file. Check the kernel log (using dmesg) 38to see whenever the driver knows your card or not. There is a line 39like this one: 40 41 cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \ 42 34xxx models [card=1,autodetected] 43 44If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to 45the driver. What to do then? 46 47 (1) Try upgrading to the latest snapshot, maybe it has been added 48 meanwhile. 49 (2) You can try to create a new entry yourself, have a look at 50 cx88-cards.c. If that worked, mail me your changes as unified 51 diff ("diff -u"). 52 (3) Or you can mail me the config information. I need at least the 53 following informations to add the card: 54 55 * the PCI Subsystem ID ("0070:3400" from the line above, 56 "lspci -v" output is fine too). 57 * the tuner type used by the card. You can try to find one by 58 trial-and-error using the tuner=<n> insmod option. If you 59 know which one the card has you can also have a look at the 60 list in CARDLIST.tuner 61 62Have fun, 63 64 Gerd 65 66-- 67Gerd Knorr <kraxel@bytesex.org> [SuSE Labs] 68
