Some notes regarding the cx18 driver for the Conexant CX23418 MPEG
|
|
encoder chip:
|
|
|
|
1) The only hardware currently supported is the Hauppauge HVR-1600
|
|
card and the Compro VideoMate H900 (note that this card only
|
|
supports analog input, it has no digital tuner!).
|
|
|
|
2) Some people have problems getting the i2c bus to work. Cause unknown.
|
|
The symptom is that the eeprom cannot be read and the card is
|
|
unusable.
|
|
|
|
3) The audio from the analog tuner is mono only. Probably caused by
|
|
incorrect audio register information in the datasheet. We are
|
|
waiting for updated information from Conexant.
|
|
|
|
4) VBI (raw or sliced) has not yet been implemented.
|
|
|
|
5) MPEG indexing is not yet implemented.
|
|
|
|
6) The driver is still a bit rough around the edges, this should
|
|
improve over time.
|
|
|
|
|
|
Firmware:
|
|
|
|
The firmware needs to be extracted from the Windows Hauppauge HVR-1600
|
|
driver, available here:
|
|
|
|
http://hauppauge.lightpath.net/software/install_cd/hauppauge_cd_3.4d1.zip
|
|
|
|
Unzip, then copy the following files to the firmware directory
|
|
and rename them as follows:
|
|
|
|
Drivers/Driver18/hcw18apu.rom -> v4l-cx23418-apu.fw
|
|
Drivers/Driver18/hcw18enc.rom -> v4l-cx23418-cpu.fw
|
|
Drivers/Driver18/hcw18mlC.rom -> v4l-cx23418-dig.fw
