- 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
