Kevin Day:
|I just purchased a new bt878 compatible card... After a lot of fiddling from
|Amancio, we got it working properly... However, I'm not able to get the
Hey, glad to hear it!
|video in on the card to work. (blue screen, no video) In vic, we're able to
|get it to work using 'port-3' using the meteor device. Amancio has asked me
|to ask you to add support for it. :)
|
|Any way I can help? :)
Well, I just caught up on the bt878 mail, and I have a few related questions:
1. Does your TV card feed all 4 Bt878 inputs?
2. What are the Bt878 inputs on your card connected to?
(tuner, video jacks, svideo jacks, etc.)
The reason I ask is this: By convention, the mappings for Bt848 input
device types -to- bktr input device ioctl #defines are as follows:
#define DEVICE TYPE
------- ---------------
DEV0 = STD VIDEO INPUT
DEV1 = TUNER INPUT
DEV2 = SVIDEO INPUT
This is fine. The app and the user don't need to know what strange way
"manufacturer X" wired up devices to the Bt848 inputs. The driver knows,
and it remaps these in a standard way to driver #defines.
The issue I'm getting at here is, shouldn't the driver internally be
mapping the DEV0 input device type #define (i.e. STD VIDEO INPUT) to the
Bt878 Mux 3 for your card? Or do you have "2" STD VIDEO inputs on your
card? Or do we have a new type of of input device that can appear on TV
boards?

|The Bt878 is an upgrade to the Bt848.
|
|Please recompile fxtv-0.47 with this tvcapture.c the problem is that your
|model has one extra MUX which Hauppauge uses for video input.
...
|Your video input is not coming from mux3 so fxtv needs to be modified
|to support it for mux3 is not specified in fxtv if you like you
|can modify fxtv and for video input specify :
|#define METEOR_INPUT_DEV3 0x08000 /* camera input 3 */
|This input is only for Bt878 for Bt848 does not support such port.
|
|Or add a new menu entry which allows you to select METEOR_INPUT_DEV3.
