There is also support in the kernel for a cx23416 mpeg encoder via the cx2388x host port though the blackbird driver, cx88-blackbird.c, which includes parts from the [[ivtv devices |ivtv driver]]. I don't have a list of the cards supported by this driver.

Introduction

The cx2388x chip is the successor to the bt87x chips; cf. PCI interface chipsets used for v4l cards.

There is also support in the kernel for a cx23416 mpeg encoder via the cx2388x host port though the blackbird driver, cx88-blackbird.c, which includes parts from the ivtv driver. I don't have a list of the cards supported by this driver.

Supported cards

There doesn't seem to be a list of supported cards in the kernel documentation; here is some information on card numbers from the driver header file, drivers/media/video/cx88/cx88.h: 

NOAUTO               UNSET

Support for some additional cards, such as the pcHDTV_HD2000, has been added since then.

Release notes

(Documentation/video4linux/README.cx88 from 2.6.12-rc2 with some added links)

This is a v4l2 device driver for the cx2388x chip.

Current status

Video

  • Basically works.
  • Some minor image quality glitches (cf. color problem patch below)
  • For now only capture, overlay support isn't completed yet.

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 PAL-BG. Other TV norms need other code ...
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) should be possible, but there is no code yet ...

vbi (cf. text capture)

  • Some code present. Doesn't crash any more, but also doesn't work yet ...

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 (use the mainline kernel; cf. How to submit patches).
  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,
