Is this an analog TV tuner? You may try my toolkit at:

Let me know if it actually works.

Data+video acquisition + playback

I would like to acquire video and data at the same time using 2 cards
(image and data acquisition). Does anyone have a vi that will enable me
to do this?
I also want to look at the data and watch the corresponding bit of
video, so does anyone have a vi to do this as well?
Thanks
Ali.

Qosmio G10 Analog video acquisition.

Please help!!!
Does anybody can help me to find a way to run analog video acquisition on a Qosmio??
I have to transfer many analog videos from a camcorder, I tried winDvd, Moviemaker, I installed Magic Video Deluxe, Pinnacle Studio 9 full version, but it seems that no one of these software is able to recognize and capture the video source. Only digital acquisition is OK. It is very frustrating!
Many thanks
Massimo

I've had a similar problem with an anlogue VCR. I sorted that out by plugging the coax output into the TV-in socket using the coax adapter that comes with the Qosmio and then tuning the TV into the video. I was then able to record the video output just like any other TV programme. The recorded TV files are saved in the dvr-ms format and this can be imported into WinDVD Creator 2 provided you have a MPEG11 decoder installed.

Video Card: MATROX MILLENNIUM G200 8MB SDRAM AGP

Hello,
I have NVIDIA GEFORCE 256 video chip installed in my machine. As there is no driver available for it. I am planning to buy a new video card that is supported by Solaris 8. When I go thru the HCL, I find that MATROX MILLENNIUM G200 (or The other choice that I want to go is Diamond Viper 770.) is supported and thinking of buying that.
1. Could someone share your experience about this video card?.
2. Will this work with out giving any problem?.
3. Or is there any reliable video card that is supported by Sol8?.
The reason I selected these video cards are because they are cheap and tested for all the resolution and color depth.
Please share your experience. Your suggestions are appreciated.
Thanks
Raj

There is a bug in the Solaris 8 FCS driver for the G400 that causes lines of text to be painted very slowly in an X window. I found this sufficiently annoying when composing mail with Netscape Messenger (the mailtool component of Netscape Communicator) that I purchased the XIG X server (http://www.xig.com), which cured that particular problem and provided noticeably better graphic performance, in general.
I've heard that a driver update for the G400 card will ship with the first Sol8/X86 maintenance release that will resolve this problem.

Video acquisition from frame grabber

I wanted to acquire image from a video camera which only has analog output. To do that, I used a framegrabber, called :"Hauppaugel analog video giditizer".
However, as I can see from the list, the framegrabber provides image with YUY 2 format and in the list of my Labview vision module, I could not find such type.
I have written a code for acquiring image which works fine with normal web cameras. however, when I want to use it for acquiring the image from frame grabber, it gives following errors:
1. Error code: 1074396120 Not an image
2. Error code: 1074396015 Cannot connect to camera, it may be in use.
I guess it has something to do with the formats of the picture, but I really don't have experience with that. Could you help me out? The code is attached.
I lookforward to your advice and thank you in advance for the help.

Hello,
First, you have to know that your camera must be Direct Show, otherwise, you won't be able to use it in LabVIEW.
If it is compatible, then you will be able to grab image using IMAQ USB, but keep in mind that this set of VI is no longer supported as IMAQdx is fully compatible with DirectShow cameras, and much better than IMAQ USB.

Is there a way to get video acquisition for LabVIEW through the USB port?

Using either the LabVIEW version 7 or lower versions.

Video acquisition framerate

Hello,
I've been trying to acquire images from a camera at 30 fps for time-sensitive image processing. Currently I have a while loop with imaq grab acquire wired to imaq avi write frame. The loop timing is controlled by a wait (ms) function. Obviously the framerate is dictated by the loop timing, which is my main problem. For 30 fps, it is 33.333333 ms per frame which causes a rounding error within the loop timing. Thus, I am getting more frames than I should because it is grabbing frames slightly faster than it should be.
I'm sure many others have solved this problem, but the solution is not apparent to me. So does anyone know how to properly control the framerate?
Thanks
-TJ
Solved!

It looks like the bind you are in is because the OS (all PCs actually) and the camera only have a 1kHz clock, so you are stuck with 1ms intervals. In software, there are always many ways so here you go:
Hack solution:
Vary the time of your delay loops: 33,33,34,33,33,34,... This fixes your round off error, but will give you up to 0.6666ms dither in your signals.
Better hack solution:
Feedback to vary the time of your delay loops: run a timer and use that to set the timing to either 33 or 34 depending on where your <1ms rounding error is at that particular time.
Expensive, best solution:
Get a camera you can set the timing in hardware.
Best solution with what you've got:
Get off of the windows 1ms timer. The structure to use is a timed loop (under timed structures in the structures panel). It will default to your Windows 1ms timer, but you can use any hardware timing you have. One of your boards will likely have a 1MHz timer, which will improve your timing and dither issues by 1000x. If you still need more, you can then use some of the hacks above.
Ultimately this is a hardware problem and would be 'best' solved in hardware. However, there are always lots of ways to do it. In fact, I'm sure the NI gurus can come up with many more.
Best of luck. Play around with these fixes and keep learning,

Want to upgrade...but...

Hello users.
I'm planning to upgrade to the CS3 premium suite (about time...) but wondering if my system spec will be able to perform with the needs of the latest suite requirements... so any advices from you "advised" users will be appreciated.
I'm now running:
AMD Athlon XP 2400+
2.00 Ghz
1.5 GB of ram
40 GB for C drive
680 GB on 5 more stream drive
Video card Matrox Millenium G450 DualHead
Sound card Creative SB Audigy
Mother Board Asus A7N8X
Windows XP SP1 (to avoid all the conflicts)
Softwares:
Adobe Premiere 6.5 with Pinnacle DV500(break box for analog signal)
After Effects 6.5
Photoshop 6.0
Everything works fine for now but want to upgrade to improve my workflow and be more competitive with all the new features that the CS3 suite offers... and I want to be sure if my computer will "take" it or if I need to adjust or also upgrade my CPU... Is it OK or what would I need???
Thanks in advance to you all
Happy editing
Kryss

I used a similar system with AE 7.0 to render over 400 GB of 1920x1080 image sequences in 16-bit, with the difference that I had 3 GB of RAM (and I avoid Matrox cards like the plague.) I'd seriously recommend to upgrade to XP SP2, 4 GB of RAM and a cheap nVidia GeForce card, such as the 7000-series.
With more RAM and a better graphics card (to make the system more stable) and XP SP2, you'll be able to work, but if you upgrade to a cheap office-type computer you'll get a system that should give you at least twice the performance of an upgraded version of your current system, for around $850:
Dell Inspiron 530:
Intel Core2 Duo Processor E6550 (4MB L2 Cache,2.33GHz,1333 FSB)
Windows® XP Professional - English
4GB Dual Channel DDR2 SDRAM at 800MHz- 4DIMMs
250GB Serial ATA Hard Drive (7200RPM)
16x DVD+/-RW Drive
nVidia GeForce 8300GS 128MB

Also note that Premiere Pro won't run on an Athlon processor!

Solaris 10 x86 w/ Matrox G450 dual head and xinerama

I have solaris 10 x86 with matrox g450 dual head and x.org x-server. The problem is to get xinerama work. When xinerama isn't enabled, two different desktops work well - or, they work, but they are pretty useless because I can't move windows between them. So, I have to enable xinerama, but it seems, that neither JDS/Gnome nor CDE haven't been built including support for xinerama.
When I enable xinerama, X.org-x-server starts fine and there's dtlogin. When I login and it passes execution to gnome, it fails and x-server restarts. Same with CDE. But if I put 'exec /opt/sfw/bin/xterm to my .dtprofile', it starts ok and I can do some testing..
% dtwm
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 149 (XINERAMA)
Minor opcode of failed request: 2 (XINERAMAGetScreenCount)
Resource id in failed request: 0x0
Serial number of failed request: 18
Current serial number in output stream: 18
% gtk-demo
The program 'gtk-demo' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 13 error_code 3 request_code 149 minor_code 2)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line<br />
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
% gtk-demo --sync<br />
The program 'gtk-demo' received an X Window System error.

If I start /opt/sfw/bin/fvwm2, it works fine too, so the problem seems to be gtk/glib/gnome and CDE. One odd thing is that, normal CDE-programs, like dtterm, dtcm, dtcalc etc. works fine. But dtwm doesn't work in xinerama mode.
So, would anyone have any suggestion what could I do? Do I have to recompile my own GNOME, or could Sun do something to the next Solaris 10 update? (As far as I understood, current Solaris 10 release doesn't include zfs yet, so there will be update soon, I think)

Hello,
I'm also using a g450.
Now I'm trying for 5 days to get it work with xinerama under Xorg and/or
Xsun.
Can anybody tell me how to get it work ?
I would like to see a working xorg.conf.
(I don't know how to configure 2 screens for Xsun. Mybe someone can give my his configuration file(s) ?)
Thanks to all who will help me !!!
p.s. here is my latest attempt of xorg.conf which does not provide xinerama for me:

? Matrox MX02

The MX02 , when importing live video (NTSC Video Signal) that format does it apear in Adobe Premiere
IE Do you have to render it before you can edit it.. When imported, Is the render bar RED or GREEN ?
If you have one, do you like it.? What would buy today ?
On the MAX option have you tried to render a file from RAW format to H.264 in HANDBREAK
and if so is the quality the same ?
Thanks Mike c.

You can capture the video as Matrox's AVI(Mpeg 2) or M2T I believe the other one is depending on whether it's HD or SD. I just always use the AVI since that handles both HD and SD.
If you bring the material into a Matrox sequence then it should not have any bar over the top and no you dont need to render it to edit it.
The current Matrox tools has a bug with the media encoder presets when you select an H264 preset. It lags out for a while and looks like the system is non responsive. Then it will allow you to change presets. Also the audio driver still has a bug in AE. If you want the Max and you can deal with a few bugs then the MXO2 is fine. We will have to see if the update fixes atleast the Media Encoder preset issue when it releases. The Max is great if going to Blue Ray. However the file based options have been limited on the Matrox Max presets. Although I was told you can change the resolution options manually.
The Blackmagic hardware runs fine with Adobe however it does not have any Mpeg 2 options for capture or H264 accleration on export. You can capture M-Jpeg or DVCPro HD though. The export options are your standard Adobe and those codecs besides uncompressed.

Video Overlay with the TV

I am trying to get my macbook to play video out to my TV through the Video Composite adapter.
I can make it clone the desktop fine but that is not what I am trying to do.
With my matrox G400 card on my PC I have been able to play full screen video out to the TV while keeping the video in the player area on the desktop window. I've been able to do with with default settings on my PC since 1999.
Here is a link which demonstrates the options in video overlay settings.
http://www.xbitlabs.com/articles/video/display/matrox-g550.html#sect2
What I am trying to do is called the Dualhead DVDMax mode. Of course I realize this is just what Matrox calls it. My nVidia card also does it but under a different name.
Does anyone know how I can make this happen with my macbook?

what do you mean not a valid function "anymore"
was it once possible on the mac and now it's not?
this seems unlikely.. i hope...
It does not work for me to "mirror" because my macbook screen resolution is much more than my television. Why should I have to reduce my macbook to a 640x480 mirrored just to play a movie on the TV? Why can't I play a movie and let my kids watch it in the other room while I continue to work on another program the way that I can with my old PC?
Also my television is in the other room so if I were to drag the video window over to the other monitor I can no longer see it in order to full screen it or whatever. the window is usually much bigger than the screen if i try to drag it across in "spaces".. but this isn't the right thing either.
I wish I knew the technical term for what I am trying to do. "video overlay" i think is too broad and there must be a more specific terminology for *full screen video playback on secondary video when played in a window on primary*
anyone know what it is?

How to start and stop video acquisition in a state machine

hello,
I'm a neuroscience student and here's what I'm trying to do: 1) trigger a GigE camera (200fps), 2) start video acquisition, 3) trigger a light that will stay on for x miliseconds, 4) trigger a valve that will blow an air puff, 5) stop the tone and the valve simultaneously and 5) stop the video acquisition 1second after 4). For that, my VI is a state machine, with a state for each trigger (ex, 1 state for trigger camera, 1 state for trigger light, ect) plus a state to "stop" and a state "time to wait". Everything was working except the video acquisition - the program would trigger the camera but only acquire one frame, because it wasn't running in a while loop and this is my first question: for a video acquisition is it always necessary to have a while loop?
I assumed the answer was yes, so I built a "consumer" loop for the camera. Putting a queue in the state "trigger camera" in the producer loop, I was then able to start the video acquisition but now the problem is to stop it in the right time. I have another queue in the "stop" state in the producer loop, but it isn't able to start the "stop" state in the consumer loop, I think that may be because the consumer loop gets "stuck" in the while loop.
I hope you can help me, the VI is attached. Thanks!
Solved!

Hi Gak,
Thanks for the suggestions. I still didn't got it to work though. I moved the stop command to inside the while loop like you said but it didn't work. The problem seems to be in the communication between the producer/consumer loops. When I run the VI in highlight, the queue message "trigger camera" leaves the producer and arrives at the consumer loop in the appropriate time, starting the "trigger camera" state of the case structure. However, the message "stop" doesn't seem to be sent by the producer loop, so the consumer doesn't receive a signal to start the "stop" state of the case structure. Can you think of anything I should change in the producer loop so that the second state (stop) is added to the queue?
About the functional global, I read about it, it seems that either that or a local variable could work, but I don't quite know how to implement it in my state machine, since the stop of the first while loop isn't activated in the "stop" state but in the "shutdown" state. It works more or less like this: after 10 loops of triggering and stopping the camera, light and valve (so after acquiring 10 movies), it goes for shutdown. Can you show me what you had in mind with the functional variable?

Video Capabilities -- Confirming Current Limitations (Record + Higher Quality Than Sorenson)

Hi,
Regarding video with Cocomo, I writing to confirm that the
current version does not provide the following two capabilities:
Recording. Acrobat Connect Pro includes record capability.
Am I correct that at this time Cocomo does not (yet) include record
capability?
Video Encoding. Am I correct that at this time Cocomo
supports only Sorenson Spark for acquisition of live video?
(Background: I have two clients seeking integrated video and text
chat applications with higher quality video for the primary
presenter. Flash Player supports playback of video encoded in
Sorenson Spark, On2 VP6, and H.264. For encoding of live video,
Flash Player (and by extension Cocomo) encodes only Sorenson Spark.
Adobe does, however, also support via the Flash Media Live Encoder
(FMLE) live encoding using VP6 and H.264. I assume that Cocomo
currently does not support integration with FMLE or any other
option for higher quality live video acquisition)
Thanks again for your support and this great new
product/service.
I look forward to Cocomo having its official commercial
release here in 2009! :-)
Best regards,
g

Hi Nigel,
Thank you for your reply.
Regarding the use cases ...
1) Union For Regular Member Meetings.
2) Pharmaceutical Training.
The first has looked at Connect Pro and the second currently
is using Connect Pro. Both cases seek both a higher quality video
for the presenter as well as to be able to record (for archive and
for "re-airing" by those unable to join live).
Regarding additional encoder in the presenter's "Player", I
think if just AIR could encode H.264 these client's use cases would
be satisfied. (These clients' goal on video quality fits a
1-to-many pattern. Requiring the presenter only to install AIR
seems a reasonably unobtrusive solution. Then, should attendee
video also be required, Sorenson via Flash Player should suffice.)
For both clients, having the hosted service from Adobe is
also an attraction (depending on pricing ;-)
Again, thanks for the great work of your team and everyone at
Adobe for bringing these solutions to the market.
Best regards,
g

Share Function using Matrox MX02mini with FAST

Using MX02 mini with Fast and v1.8 drivers on MacPro 2.66GHz Quad, 7GB RAM having the latest versions of FCP and Snow Leopard plus all updates as at 1st November. Unable to export using the Share function although can export using QT conversion.
When attempting to use the share option the following message appears:
3x NSException raised by 'NSGenericException', reason = 'Hardware communications error with encoders 0xE00002BC (-536870212): open Session'
Is this normal or a known problem. Any suggestions welcome.
Thanks in advance,

Hi Andy,
Whoops! Yes, I meant MAX, must have been an premature 'senior moment'. Anyway, many thanks for your quick response.
My workflow is as follows:
a) Import XDCAM EX clips using File and Transfer
b) Audio Video Settings: Sequence - Matrox MX02,Apple ProRes 422 (HQ) 1088i 50 48K; Capture Preset: As Audio Video Settings; Video Playback: Matrox MX02 Mini 1080 50i YUV 8bit; Audio Playback: Matrox Mini02
c) (Easy setup: Matrox MX02 1080 50i)
d) Sequence settings: for 108050i plus QT Compression: XDCAM EX 1080i 50
e) Render Settings; Apple ProRes 422 for XDCAM - have also tried 'same as sequence codec'
Then to export using Share:
File>Share>(other) Matrox H264 1080 25 for BluRay>Export = FAILURE
The Matrox setting works for Export using QT Conversion and in Compressor.
I hope the above makes sense,
Geoff
