Re: ZC0301 webcam, successful trace from spca5xx driver

Re: ZC0301 webcam, successful trace from spca5xx driver

[test.r test.r]

Hi,

Using the old spca5xx with Debian kernel 2.6.18 the webcam is working.
"Release 0.60.00 as spca5xx-v4l1-goodbye" available in Debian etch.
The traces below may help someone wanting to port this webcam to the
new driver architecture.

Have a good day,
Guillaume


Below, the dmesg after modprobe spca5xx debug=5 and plugging the webcam:

Hi Guillaume,

The spca5xx-v4l1-goodbye is for kernels < 2.6.11. Does the version
gspcav1-20071224.tar.gz work too?

I checked the source code of both gspca v1 and gspca v2 without finding
any difference. A trace of gspca v1 may help. May you send me the full
trace of the start of video streaming? (dmesg from 'spca5xx_open' till
the end - please, no more than one second of streaming)

Thanks.

TeVii S470 status?

[Claes Lindblom]

Hi,
I'm looking for a new DVB-S2 card for my linux server and I wonder if
anyone have tried the TeVii S470 in linux with DVB-S and S2 and whats
the status of it. Is it stable and good support, no problems like the 
TT3200 (A problem with locking high symbol rate channels (DVB-S2 30000
3/4 transponders) .
I need to tune channels with a high symbolrate at 30000.
It does not say much in linuxtv-wiki but the manufacturer has s2api
driver at there homepage.

How is it compared to Hauppauge HVR-4000, Nova HD S2 or the TT S2 1600?

Thankful for all help.

Best regards
Claes
