 |
|
Upgraded kernel to 2.4.19-gentoo-r10 from r9.
Now xawtv/v4l no longer works. XawTV starts, but with a black screen and this error message. I have the bttv-drivers compiled in. Card is a Hauppauge WinTV, BT848.
WARNING: couldn't find framebuffer base address, try manual
configuration ("v4l-conf -a <addr>")
Warning: Cannot convert string "-*-ledfixed-medium-r-semicondensed--39-*" to type FontStruct
ioctl: VIDIOCCAPTURE(int=1): Invalid argument
This is what v4l-conf has to say:
mode: 1024x768, depth=16, bpp=16, bpl=2048, base=unknown
/dev/video0 [v4l2]: ioctl VIDIOC_QUERYCAP: Invalid argument
WARNING: couldn't find framebuffer base address, try manual

According to v4l-info my card is detected as a bt878, but is is a bt848. Can this have anything to do with the problem.
If I want to try and set the address manually, what value should I use? Where can I get that? |

| Now I´ve tried to compile the bttv driver as a module, and pass the card= -argument when loading the module. Same result. |

Could there be some kind of mixup of v4l and v4l2?
Like in the v4l-conf output reads v4l2 first and then v4l?
Also started up the old kernel (with which TV worked very well before) and now that is also giving the same error message.
Could the devices is /dev/v4l have been overwritten with something from v4l2? Nobody who knows anything? |

Does anybody know, is the new v4l2 in kernel 2.4.20? Or is it still the old v4l?
My card is obviusly detected wrong, as a bt878, while it is a bt848, and has always worked very well with v4l. |

I'm also having problems. I just got a Hercules Smart TV card, which works fine in windows. It's a BT 878 based card.

That looks like a confused conf program to me, but this is my first tv card.
I've got a /dev/v4l/vbio & /dev/v4l/video0 and /dev/video0 is a sym link to /dev/v4l/video0
Running xawtv giver:

Anyone have any ideas?
*EDIT* Adding some more info..
I'm pretty sure my card has a philips tuner, so I modprobe as so:
| Code: | | modprobe bttv tuner=5 |
...Producing...

I think I'm going to try Kernel 2.4.19.
Looks like you need to comment
| Code: | | # Option "omit xfree86-dga" # don't initialise the DGA extension |
from XF86Config |

I got tvtime to work! Really strange, because xawtv till complains about no video grabber device available.
I'm running 2.4.19 now, but I'm going to try tvtime with 2.4.20.
Now to get freevo, mythtv and xmltv working... |
