-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
