literal string comparison with ==

2006-12-18T17:52:18Z

I believe the check for
Dazzle Fusion Model DVC-90 Rev 1 (SECAM)
never returns true.

We should treat the code with the patch attached.

Supported devices

2005-08-30T12:38:36Z

I bought in France a Hauppauge WinTV USB which device
ID is 0573:4d25. I report it works fine with the
usbvision driver. The exact name written on the label
is "Model 40209 Rev B234".

Thankyou for the great work on the driver.

cvs fails to compile with kernelversion <= 2.6.11

2005-07-21T13:44:17Z

When attempting to compile usbvision from CVS (on Suse
9.3 with kernel 2.6.11.4) make fails with error

This is because the declaration of tun_addr is not
protected with a "#if LINUX_VERSION_CODE >
KERNEL_VERSION(2,6,11)" statement.

The attached patch and replacement file fix this problem.

misc fixes

2004-09-21T12:47:39Z

Hi Dwaine,

I modify customdevice_process to get rid of this warning :
usbvision.c:5597: attention : ISO C90 forbids mixed
declarations and code

I fix 2 potential NULL pointer accesses in
usbvision_configure_video and in usbvision_alloc.

I also move the video norm setting for saa711x (from my
last patch) from usbvision_setup to attach_inform. It
seems to be a more appropriate place.

init of video norm in saa711x

2004-09-16T16:10:11Z

Hi Dwaine,

a little patch to init the video norm during
usbvision_setup call
(usbvision_setup is the only function modified by the
patch).
I think (i can be wrong) it's the right place to do it.

This way i have SECAM mode at start up with xawtv as
expected.

Feedbacks are welcome.

yuv422 palette support

2004-09-15T11:33:22Z

Hi Dwaine,

i add full support for VIDEO_PALETTE_YUV422.
usbvision.h and usbvision.c are modified by the patch.
It works with the 3 isocMode (0x03, 0x14, 0x60).
I test it on my wintv usb (NT1004 / saa7113) with
xawtv, xawdecode, mplayer and a homemade grabber, it
works well.

Misc minor fixes and cleanups

2004-08-16T11:02:42Z

Attached patches fixes a few minor issues and cleans up
a few things.
- remove the static verbose variable -- it isn't used
anymore.
- Adjust the internal memory layout and corrected the
comments.
With compression enabled it's now:
UR: 0x0E200-0x3FFFF
FDL: 0x00000-0x0E1ff
VDW: 0x0E200-0x3FFFF
I think that's what the original author intended,
- Allocate the scratch buffer and the decompression
intra-frame buffer with vmalloc instead of kmalloc.
Allocation of such large buffers with is more likely to
fail (due to memory fragmentation).

Attached patch adds support for the Hauppage USB Live
Model 600 device (0x0573, 0x2d01)
