Ok, so cameras are red...

Thank you guys !

At last I managed to see some images from my refurbished TW6800 based card also with zm using the tw68 device driver .

Working settings for zm and my camera are:

Code: Select all

Device format  PAL I
Capture palette BGR 24
Capture Witdth 384
Capture Height 288

CAPTURES_PER_FRAME = 2

With bigger resolution than 384x288 zm does not work (but mplayer does).
I will try changing dimension of shared memory later.

And now bad news: the images I get are somehow corrupted (see below) and after a while (from few minutes to half an hour) the device driver stops working and zm gets errors.

If I remove the device driver and install it again (make instmod) , I get images again.

Here some more informations:

Here a picture :

What are those black an green stripes on the left border?
(The camera is OK because using the bt878 card the image is good.)

Robby,

Looks like you have the same card as me.

Unfortunately, the driver isn't specifically designed to work with 6800 cards. I got the exact same bars on the side of my image. I also got the same thing with the driver stopping after a while.

Frack... I thought someone was working on another driver, but looks abandon

http://tw98.sourceforge.net/

wbrack · Post by **wbrack** » Fri Jan 15, 2010 1:23 am

robby,

Thanks for the further info on the tw6800. That card's very difficult for me, because I don't have any card with that chip for testing (mine are all tw6802 and tw6805).

The timeout messages are certainly a problem, but I'm pretty sure that's the same problem others are reporting (and I'm currently working on that). I think your "Device format" should probably be PAL (rather than PAL I), but with the current version of the driver it shouldn't make any difference. For the vertical bars on the left side of the picture, I would guess that is caused by the driver code which does the picture "size", setting up registers including the delay of the position of the horizontal sync pulse. Apparently the tw6800 has some differences from the tw6802/tw6805 in these settings. We can work on that after some of the other problems have been resolved.

For the rest, I'll need to get a log of the driver's messages when the problems occur. I'm not sure what your level of knowledge is for linux setup; I'll be glad to give more details on whatever additional information you need to do this. To produce this log, do the following

Code: Select all

insmod tw68.ko video_debug=7

That will produce kernel messages with "facility"="kern" and "priority"="debug". I'm looking for messages like this:

Code: Select all

Once you have that log, email me a copy of it (my email address is given in any of the source code files) and I'll see if I can guess what's happening.

I did insmod tw68.ko video_debug=7 but it gave me insmod: error inserting 'tw68.ko': -1 File exist, I did Make clean then make, and insmod: error inserting 'tw68.ko': -1 File exists, but still the same error...

wbrack · Post by **wbrack** » Fri Jan 15, 2010 8:31 am

whatboy,

uhhh... perhaps "rmmod tw68" to remove the one already installed?

can someone please help me ?

robby · Post by **robby** » Fri Jan 15, 2010 2:17 pm

antov,

if you have installed mplayer, you can try to do the followings in tw68-tw68-v2 directory:

rmmod tw68.ko
make run

to see if your card and camera work out of zm.

If this works for you (like it worked for me) it means that you have to tune up your settings on zm.

antov · Post by **antov** » Fri Jan 15, 2010 11:41 pm

robby, thanks for your answer, but i don't have installed X on this machine

whatboy · Post by **whatboy** » Sat Jan 16, 2010 5:21 am

So I did what you told Me, AND incremented the resolution to 740x480 and CAPTURES_PER_FRAME = 3, so is recording at ~ 4.5fps... and hasn't crash since then...

robby · Post by **robby** » Sat Jan 16, 2010 6:11 pm

antov,
mplayer works also without X, it can use vesa compatible or svga video cards
(even EGA!!) see documentation at http://www.mplayerhq.hu/.
It is very important to understand where the problem is : device driver or zm settings.
Sometimes also cameras, cables and connectors make troubles

antov · Post by **antov** » Sun Jan 17, 2010 12:15 pm

robby thanks
the camera is working on my DVR geovision device
the problem is not in the connections to the camera
i will try mplayer and i will post the results
thanks a lot

robby · Post by **robby** » Mon Jan 18, 2010 7:58 am

moorsey and wbrack,

I have played a little with my TW6800 based card and the device driver settings.
Changing the h_delay value from 3 to 133 in souce file tw68-video.c (line 20) , I can now see images without black stripes. Stability issue remain.......more playing needed.....
