My problem is i am not able to play video in AVTransmit2.java.
If i create a player using datasouce, eigther i get player already occupied or a black screen.
please help me running the video on Transmit side as well.

i have same problem. works fine booting back up to Snow Leopard, but it's a drag to get windows to work. you can also chose to boot to last known working configuration in lieu of system restore, but it's still cumbersome.

Streaming video through Windows Media Player using USRP

Is there any document / guide or any example explaining how to do streaming through Windows Media Player using USRP.
Thanks
JK

Joseph,
I have been looking a bit more and have found a few examples that seem similar to what you are looking to do. Here is an example of video streaming using USRP RIO or FlexRIO https://decibel.ni.com/content/docs/DOC-40747. I also found an example of doing wireless streaming of video https://decibel.ni.com/content/docs/DOC-22728. Sorry I was unable to find these in my first post; I hope they help!

Unless you held down the Command key when dragging the iPhoto Library package to the flash drive you only copied the library. How is the flash drive formatted? If it was not OS X Extended (journaled) the integrity of the library's internal structure was probably compromised.
If you don't have a current backup of your library do the following:
1 - launch iPhoto with the Command+Option keys held down to open the First Aid window. Be sure to follow the circled recommendation in the screenshot.
2 - run Option #4, Rebuild Database.

Black Screen on Real Player and WMP

Hi guys, i have tried this with a couple of cards and just recently i got a new card to hopefully fix this issue. I have the MX400 GeFroce 4 128MB. I get picture on my computer and TV when i have set it to clone and everything but when i go to play a streaming video file from Real Player all i have is a black screen in any size fullscreen or windowed. Same with Windows Media player. Is there a fix for this or is there a setting i have to change....any help would really be appreciated thanks....Using all the latest drivers and bios.....thanks..

That is what the Apple Store says at least... can you order it with the Intel CoreDuo?
In other words Flip4Mac should have no problem on your computer. If you are having trouble I suggest checking out the Flip4Mac site.

Full screen windows media player

Greetings - I am having issues trying to open a .wmv file
full-screen. I am simply using:
on mouseUp
baOpenFile( the moviePath & "01.wmv" , "maximized" )
end
I have made several attempts to at code to make sure it opens
in full-screen, but found no simple solution. I am running dual
monitors and this will open up in the second monitor within the WMP
- full screen.
Thanks all -
bS

Hmmm … maximizing the application isn’t exactly
the same as full screen playback (ie: without all the interface
elements). If you want to maximize the application on a given
monitor the following might work:
Open media player in normal mode
Use baMoveWindow to place the player on the monitor of your
choice
Use baSetWindowState to maximize
You could use baMoveWindow to both move the window and make
it full screen although I don’t think the OS will recognize
the window as being maximized.
To use Buddy API’s window functions you’ll need
the WinHandle for your media player window … look closely at
baFindWindow and/or baWindowList … these functions I have
used. Make sure you use the window title to find the handle, using
the class is dangerous because there is no guarantee that media
player will be the default player for wmv on any given system.
If your projector is windowed and can be dragged by the user,
and if you want to identify which monitor shares the greatest area
with the projector stage I wrote the following function. Works fine
with single monitor systems. Note that if the user somehow manages
to push the projector off all screens the primary monitor is
returned. I’m not sure what will happen if you call the
function while the projector is minimized (not possible in my use).
I suspect the primary monitor would be returned but I’ve
never tested that, it all depends on what the value of
_movie.stage.rect is when the application is minimized. If
it’s rect(0,0,0,0) there’s no problem, if it’s
void the following code would need to be modified to check the
application state first.

Black Screen with Flash Player

Has anyone had the issue with getting a black screen when clicking the flash player file, this is what i am trying to
get working:
http://www.aemo.com.au/planning/2010ntndp_cd/html/interactivemap.htm
I am using the latest version of 10.3.183.7 with internet explorer 8, windows xp 32 bit for the vast
majority of pc's accessing this site.
I cannot get this working. Apparently it was an issue with a previous version and Adobe produced this
one to fix.
I urgently need to get this working.
Any suggestions, assistance greatly appreciated.
Thanks
Lawrence

Hi Lawrence,
I also experienced the same issue when I visited the page using Flash Player 10.3. However, Flash Player 10.2 plays the content properly.
You can download Flash Player 10.2 debugger version from: http://fpdownload.macromedia.com/get/flashplayer/installers/archive/fp_10.2.159.1_archive. zip
Extract the zip file you download. flashplayer10_2r159_1_win.exe is the installation file.
Thanks

890fxa-gd65 black screen due to usb use ?

To discribe the problem in simple words: I noticed that my new build system stops working after approx. 20 minutes when I play a game (burnout city paradise) with my logitech gamepad, hence usb. Screen goes black, system is totally not responding to anything, but fans still run. I have to shut it down with the button on the psu. But after that I can restart my system right away. When I play any other game that doesn't involve a gamepad, the system tends to do the same black screen thing after 2 hours of playing, but only if I have usb stuff plugged in (printer, external hdd's and a card reader). Again, hence usb. As soon as I unplug everything, exept for the mouse and keyboard, it seems that I can play without end, but sometimes the black screen thing still occurs. I have been reading similar post on this problem in this forum, and on the internet, and tried the sollutions suggested, (in the bios,ver 18.3, cell menu, changing timing from 1t to 2t, switching from unganged to ganged mode) but that didn't help.
This is my setup:
890fxa-gd65 mb with bios version 18.3
AMD X4 II 965 AM3 Black [email protected] Mhz
Geil 8 gig DDR3 Value Plus pc1333 Dual channel memory kit (2x4gig)
MSI R6850 Cyclone Graphics Card.
Samsung HD, 1 TB, HD103SJ F3
Club 3D psu, 1000w
Windows 7 ultimate, 64bit.
If I should place screen shots of CPU-Z here, let me know. But i hope someone can help me, because I'm running out of options. I don't want to RMA this board just jet.

do you use windows 7 chipset drivers?
or msi chipset drivers? ==> http://www.msi.com/product/mb/890FXA-GD65.html#/?div=Driver&os=Win7%2064
also do you have SP1 installed?
I use the msi chipset drivers, and SP1 is installed.
But something weird just happened. I just tried to play a game with "Battlefield Bad Company 2", single player. It took a while trying to load the level, and then, all of a sudden the screen went black and the whole system was not responding. Had to shut it down with the power button on the PSU. And could restart immidiatly after that. And I mean Windows. Not the game....... I'm puzzeled What I can do is that I try to do the same thing, play a single player game with BFBC 2, and see what happens......
Edit:
As I wrote, I went back to the game. Now it had no trouble loading the level. And I could play. I didn't play it for an extended period of time. Just to see if it works. And as I said, it did. This is becoming a weird puzzle.

How can I plott data from a text file in the same way as a media player using the pointer slide to go back and fort in my file?

I would like to plott data from a text file in the same way as a media player does from a video file. I’m not sure how to create the pointer slide function. The vi could look something like the attached jpg.
Please, can some one help me?

Plotting from a text file like a media player example.jpg ‏61 KB

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

Premiere pro cc 2014 black screen or "media offline"

Almost impossible to do much work in Premiere CC 2014. I use 3 machines in business and Premiere doesn't work with any of them for long. I can be editing fine for about an hour then suddenly my program monitor goes black or says media offline. The only way I can get it back is to reboot about 4-5 times before the project will load again. This happens regardless of where the media is stored, what version of Mac OS is used, or what plugins are used. Anybody else experiencing this?

Hey John! Thanks for the help! So far I've encountered the issue on three different macs. Two are stock iMacs so some AMD chip. The third and least problematic is a desktop running a GTX 780 with CUDA 6.0.46. I will have to check on the two iMacs on Monday... I'm updating the Cuda for the desktop to see if that changes anything.

Using Yosemite - cannot project screen onto TV. Get bits and pieces or black screen. Have been using same setup for years.

Hi, edward.
Thank you for visiting Apple Support Communities.
I understand that you are having a display issue with your MacBook Pro on your TV. I would need a little more information regarding how you are connecting your device and what content is being displayed to provide a better answer. However, here is the best troubleshooting resource to go through when experiencing these symptoms.
