| Hans Verkuil | 1c1e45d | 2008-04-28 20:24:33 -0300 | [diff] [blame] | 1 | Some notes regarding the cx18 driver for the Conexant CX23418 MPEG |
| 2 | encoder chip: |
| 3 | |
| 4 | 1) The only hardware currently supported is the Hauppauge HVR-1600. |
| 5 | |
| 6 | 2) Some people have problems getting the i2c bus to work. Cause unknown. |
| 7 | The symptom is that the eeprom cannot be read and the card is |
| 8 | unusable. |
| 9 | |
| 10 | 3) The audio from the analog tuner is mono only. Probably caused by |
| 11 | incorrect audio register information in the datasheet. We are |
| 12 | waiting for updated information from Conexant. |
| 13 | |
| 14 | 4) VBI (raw or sliced) has not yet been implemented. |
| 15 | |
| 16 | 5) MPEG indexing is not yet implemented. |
| 17 | |
| 18 | 6) The driver is still a bit rough around the edges, this should |
| 19 | improve over time. |

| 22 | Firmware: |
| 23 | |
| 24 | The firmware needs to be extracted from the Windows Hauppauge HVR-1600 |
| 25 | driver, available here: |
| 26 | |
| 27 | http://hauppauge.lightpath.net/software/install_cd/hauppauge_cd_3.4d1.zip |
| 28 | |
| 29 | Unzip, then copy the following files to the firmware directory |
| 30 | and rename them as follows: |
| 31 | |
| 32 | Drivers/Driver18/hcw18apu.rom -> v4l-cx23418-apu.fw |
| 33 | Drivers/Driver18/hcw18enc.rom -> v4l-cx23418-cpu.fw |
| 34 | Drivers/Driver18/hcw18mlC.rom -> v4l-cx23418-dig.fw |
