| 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 |
