1 | Some notes regarding the cx18 driver for the Conexant CX23418 MPEG |
| 2 | encoder chip: | |
| 3 | ||
| 8f993573 HV |
4 | 1) The only hardware currently supported is the Hauppauge HVR-1600 |
| 5 | card and the Compro VideoMate H900 (note that this card only | |
| 6 | supports analog input, it has no digital tuner!). | |
| 1c1e45d1 HV |
7 | |
| 8 | 2) Some people have problems getting the i2c bus to work. Cause unknown. | |
| 9 | The symptom is that the eeprom cannot be read and the card is | |
| 10 | unusable. | |
| 11 | ||
| 12 | 3) The audio from the analog tuner is mono only. Probably caused by | |
| 13 | incorrect audio register information in the datasheet. We are | |
| 14 | waiting for updated information from Conexant. | |
| 15 | ||
| 16 | 4) VBI (raw or sliced) has not yet been implemented. | |
| 17 | ||
| 18 | 5) MPEG indexing is not yet implemented. | |
| 19 | ||
| 20 | 6) The driver is still a bit rough around the edges, this should | |
| 21 | improve over time. | |
| 22 | ||
| 23 | ||
| 24 | Firmware: | |
| 25 | ||
| 26 | The firmware needs to be extracted from the Windows Hauppauge HVR-1600 | |
| 27 | driver, available here: | |
| 28 | ||
| 29 | http://hauppauge.lightpath.net/software/install_cd/hauppauge_cd_3.4d1.zip | |
| 30 | ||
| 31 | Unzip, then copy the following files to the firmware directory | |
| 32 | and rename them as follows: | |
| 33 | ||
| 34 | Drivers/Driver18/hcw18apu.rom -> v4l-cx23418-apu.fw | |
| 35 | Drivers/Driver18/hcw18enc.rom -> v4l-cx23418-cpu.fw | |
| 36 | Drivers/Driver18/hcw18mlC.rom -> v4l-cx23418-dig.fw |
