LT1421 as a general video output device

I know the LT1421 is generally used as a secondary monitor for one's PC, but I was wondering if it would function as a video output device for hardware such as a USB digital microscope, or a document camera.
Imagine I have a digital microscope with an AC adapter as well as a USB video output. Could I plug the USB from the digital microscope into the LT1421 and not only power the display via the microscope, but also view the microscope's video?

Unless these devices support displaylink technology then no it won't work.

Am I Lame? Video Output Device issues

It's been a while since we've used Final Cut Express, so we're a little rusty. A lot of it is working fine, but for some reason, it cannot connect to the video output device. I even tried reinstalling final cut express with the camera turned on and plugged into the firewire (I read that somewhere), but it made no difference. I searched these forums and found no reference to "video output device" or "cannot connect". So, any help for me out there?
The stats are - Final Cut Express 4, brand new mini DV camera (becoming obsolete, I know), firewire from the Mac to the camera and video out to the TV. FYI - the camera to the TV is fine...and the camera IS set to "play" mode, as opposed to "record" mode.
The error message mentions that it could either be an issue with the camera connection, OR it might be a conflict with the audio input device. Not sure why that would be, but if anyone has any ideas on how to investigate that further, that might be helpful. We do run Logic 8 and have an Echo soundcard installed with 2 1/4 inputs and 2 1/4 inch outputs. (in case anyone cares).
One last thing - I know I'm theoretically not running a good enough processor, but I don't think that's the issue. Logic 8 has the same requirements and runs great, and FCPExpress doesn't seem to be having any issues in terms of processing power.
Thanks again.

Yes, I did have that selected...thanks, though. Now, my audio has suddenly stopped working. No idea why. I have tried restarting the program a couple of times (which helped before, when the audio quit working). But now, that's not helping either. I don't know what heppened - All I did before the audio stopped working, was I shut down the computer and the camera and unplugged it all and replugged it and restarted. I did that to try to help the video playthrough problem (which it didn't help) and now I have no audio. ****, this is frustrating. Sigh.
Just FYI - we decided to unplug the camera from the system, since we couldn't get the video to play through to the TV anyhow. When we did that, the audio started working (just on the computer). I guess the playthrough issue was affecting the audio as well. Sigh. Any help is much appreciated.

TV (video) output from new nano looks very good!

Just a comment for those who may be wondering how the video quality on the new iPod nano looks when output to a TV. I have one of the old iPod AV docks with the s-video port and the new nano seems to work fine with that combination (using a standard s-video cable between the dock and the TV). Thus far I'm really impressed with the video quality, I can't see a single problem, the color is good, the quality and sharpness is as good as I've seen from any iTunes Store content, and as far as I can tell the frame rate is fine (no stuttering, skipped frames, or problems with audio sync). I'm amazed that such high quality video can come from such a small device. If it continues to look this good (after viewing more content and after more testing) then I think Apple may have "hit one out of the park." This thing could turn out to be the most popular iPod yet (if you have any interested in video and still want a small device).

I just found out that the video out (TV) on the new nano supports video playlists so you can create playlists for back-to-back display on the TV. Not even the AppleTV will do that (even though the latter has been a highly requested feature for the AppleTV since day one). In fact, if you can do without the on-TV menus you may find that the nano is a better video output device than is the AppleTV (that is, the menus system on the nano doesn't appear on the TV output).
Also, I just competed a few hours of video playback to my big-screen TV from the nano and I'm still impressed. No video problems at all, looks very good considering the quality limitation from the content that is currently on the iTunes Store (limited to standard definition, no HD movies, HD TV, or HD music videos as yet).

Firewire video output in high def?

Hi all,
I currently use a Canopus ADVC110 to firewire-output my video inside Logic to my beamer in "lo res" PAL DV format. However, the beamer supports up to 720p HD resolution so I'd like to have a firewire video output device than can handle this higher output resolutions (eg through HDMI or component). Canopus doesn't seem to have any capable products.
Anyone know of any options?
Or does it not exist due to limitations I'm not aware of?
Thanks!

assimilation is the bomb. the bomb.
i have been playing it repeatedly from the demo player at symphobia. i think i heard about 2 bars of it and by mouse automatically went to the buy button.
i have to tell you i am the stingiest bloke out there when it comes to buying stuff for the studio. i could end buying all manner of stuff and have a huge amount of things that i hardly use or don't have time to learn that could be covered by other things i do have. i keep a very basic setup and prefer to design my own sounds from scratch. i (we) have recorded quite a few orchestral FX we like to use, but there is never enough. symphobia is going to perfect for my next 2 projects - one of which is a very big one. unfortunately it may not arrive in time. there will be live records in prague but it won't cover everything and i am a little concerned by the reports i have heard from the other composer on the project.
there will be some london recordings but they will sweetening only.
sorry to hijack your thread BTW. i have long admired your music and this was the first opportunity to tell you so.

NO Audio output Device is installed as well as NO sound, video, or game tab in the device manager

Here is the issue I had with with my Compaq F700 series laptop. The sound was working one day and then not working the next. Over the volume icon there was a big red X and the warning that No Audio output Device is installed. I also found that there no longer was the sound, video, game tab in the device manager. It had gone missing.
I couldn't use most of the fixes as they require having the sound, video, game tab available and this tab was, as I said missing. I tried reinstalling the sound drivers from the manufacturer’s website as well as using the driver re-install, but at each attempt it would fail as a result of not having any audio devices installed on the computer.
I tried doing the system restore and rolling it back but the problem didn't get resolved. What eventually worked was restoring the system to a MUCH earlier date, like a month prior to the problem. When the restore finished the sound was still not fixed. HOWEVER, the computer OS (WINDOWS 7) needed to re-install a bunch of updates and after the updates were installed, everything was working. I suspect that the original issue was a bad update (the updates didn't install correctly) and that by rolling the system back to a time prior to the bad updates and then re-installing the update was the fix.
With that said, if the restore option doesn’t work or can’t be done I would try looking through the add/remove programs in the control panel and uninstall the most recent system updates, then restart computer and let the updates re-install.
Good Luck

Only option that I see in the BIOS is under Security. Audio Device: Hidden or Available. It was set to available and I left it at that. Still no audio.
Really? Nothing? This computer is one year old. Absolutely no reason for this to be happening. What a joke.

[SOLVED]X11 video output only with ati open source drivers

Hi everyone,
my nvidia graphics card died recently and I replaced it with an ATI Radeon HD 4870, which in hindsight might have been a mistake.
I installed the catalyst driver at first, ran into some problems, finally decided to switch to the open source xf86-video-ati driver. Followed the ati wiki, but ended up with X11 video output only. Can't watch anything full screen, general performance is sluggish. The output of xvinfo is:

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
Thanx

I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...

Is there a way to have Firefox respect the default audio output device when it has been changed while Firefox is open?

I have been a Firefox user for many years and I still use it as my primary browser. One problem that has bothered me for years is the fact that when Firefox is open and I change my default audio output device, Firefox doesn't respect that change and continues playing audio through the device that was originally being used. Even if you stop the audio and continue playing, the output device doesn't change.
Is there any way this can be configured in Firefox? Now if I listen to music online (e.g. Soundcloud) I always use Chrome since it's respects the default audio output device change even while in the middle of playing audio.
Reproduce:
1. Start playing audio (e.g. from a YouTube video; HTML5 and Flash are affected)
2. Change your default audio output device
3. Audio will continue to play from original output device
Thanks!

This is the same issue that has plagued me for years. I always thought that this was a Flash plugin issue, but it does occur on HTML5 as well. A friend of mine verified that this does not occur in Linux, but only on Windows. It would be great to have this fixed, as it's honestly the only thing that's making me use Chrome all the time, as I don't want to have multiple browsers open.

Is there no way to direct an AIR app's audio to different audio output devices?

I'm needing to make a couple of our AIR apps select certain audio devices to send their audio output to, and last year, somebody mentioned possibly using native extensions to do this. I had to start working on other things for a while, but I've come back to this (for the moment), and I've basically learned how to create native extensions.
But so far, they don't seem to provide me any special access to anything going on under the hood of an AIR app. When you stream live audio in through RTMP or RTMFP, the details of the audio are hidden from you. There doesn't appear to be any place where you can actually access the audio bytes that are being sent over the wire. You can specify a certain SoundTransform object for the NetStream to use, but that class is final and a vanilla Flash construct, so even if it may have a way to access the audio bytes, they're not acessible at all.
It really looks like, when a NetStream object starts streaming in live audio, there is no way under the sun to access the audio bytes and direct them to a certain audio output device, with or without extensions. Is this so? It would be unfortunate if Adobe didn't allow this, even through native extensions. Thanks.

Couple quick thoughts..
Limits are important. There's a large amount of work done to keep a clear separation between a users decision and a developers decision. For instance, you can't change a users default audio output because that clearly violates a users decision. That said, here's a whole mess of people debating the issue and actually eventually an undocumented COM API you can find that will actually let you do it in Vista/Win7 (but not 8), however don't expect that to be a 'good thing to do':
http://social.microsoft.com/Forums/en-US/9ebd7ad6-a460-4a28-9de9-2af63fd4a13e/programatica lly-setting-the-default-playback-device-and-recording-device?forum=windowspro-audiodevelop ment
You might want to get a beverage before reading that.
Aside that, RTMP is secured, which is why you can't gain access to the bytes. The entire purpose of it is to assure media developers that their media can't easily be copied/stolen. Adobe doesn't document their method of securing streams but they do publish the RTMP specification. It's entirely possible for you to create your own RTMP server and encryption method while delivering a RTMP stream to custom client that you code yourself which can read the stream. Here's the spec:
http://www.adobe.com/devnet/rtmp.html
So I'd say it would be unfortunate if Adobe did give you access to the bytes. You might as well just hand users a mp3 of whatever song is playing because they would steal media left and right.
That isn't to say you can't use a multitude of ways of getting the data going across the default output device. Plenty of apps (fraps/etc) capture video and mixed audio streams. But Adobe isn't going to give you the keys to the kingdom and let you decrypt their protected media protocol.

No audio output device is installed - Satellite C855D-S5950 - Windows 8 64-bit

Toshiba laptop

RAM: 4GB.
Hello,
I have my friend’s Toshiba Satellite C855D-S5950 with Windows 8 (64bit) that about a year old. Some months ago the sound stopped working. He asked me to take a look at it. I have researched this issue and found others have encountered his problem as well.
Currently, the sound icon has a red x, “No audio output device is installed.”
Things I have tried so far to try to fix this:
I went to the Device Manager > Sound, video and game controllers. I have "Realtek High Definition Audio" listed with the little yellow caution icons on them. I have tried to disable, then enable it. I have tried to uninstall the sound driver from the Device Manager. I would restart the laptop, and let the driver reinstall itself, to no effect. I have tried downloading the latest drivers from the Toshiba website. I have tried un-installing the driver while in safe mode from the Device Manager. As well as from Programs and Features. There were no positive change to the audio though, still the same message. The Realtek driver won't finish installing and throws the error: "Install Realtek HD Audio Driver Failure!! [Error Code: 0x000000FF]"
I have gone to Control Panel > Sound, under both the Playback and Recording tabs, it says "No audio devices are installed."
My friend was previously unaware of how to restart or shut down his Windows 8 laptop (as was I until I started investigating this problem for him). I mention this because there are no useful System Restore points to go back to for him.
I have also tried Using the Toshiba Application Installer as well to re-install the driver after un-installing the Realtek Audio driver from Add/Remove Programs. I went to Desktop Assist >Support Recovery > Toshiba Application Installer.
Realtek Audio Driver 6.0.1.6743
It loads most of the way then I get:
"Install Realtek HD Audio Driver Failure!! [Error Code: 0x000000FF]"
I have also tried the following links for additional troubleshooting:
http://forums.toshiba.com/t5/Audio-Sound-Knowledge-Base/Windows-8-Troubleshoot-no-sound-with-Windows...

It was also suggested in the above thread I remove the Microsoft UAA Driver, but could not find this driver on my friend’s system.
Plugging in headphones, toggling the speaker volume controls on the keyboard has had no effect.
My friend has also misplaced his install discs, so I am looking for any solution which does not require the install discs.
Any help would greatly be appreciated.

Recovery media is created from the hard drive. You can make it using Toshiba Recovery Media Creator. You can also perform a full system reset to factory defaults using the information on the hard drive without using external recovery media. That sounds like the best course of action now. To do so, use Windows+C > Settings > Power > SHIFT + Restart > Troubleshoot > Reset your PC.

Have you tried holding the Windows key and tapping the P key?
As there is no support for Windows 7 for your laptop by HP at this writing, this may indeed be difficult.
Have you checked in Device manager to see if any drivers have a yellow exclamation mark next to them?

S-Video output on Z61t

I am driving myself crazy trying to get my s-Video output to work on my Sony Plasma TV. My Z61t has Mobile Intel 945. I have updated to the most recent drivers.
Everytime I try to validate TV settings using the Presentation Director it says I do not have a TV connected.
The s-Video port is working just fine on my Wife's Toshiba laptop. What gives?
I cannot get the settings to show "Generic Televison" or anything like that. I also try a tip from the Intel list, which did not work.
I also noticed that I do not have the Intel Accelerator menu option on my desktop, right click menu.
Has anyone made this work successfully and if so how, step by step please.

Concerning: VGA monitors using an Aluminum Powerbook G4 PowerPC 2004 15"-screen 1.5Ghz
The DVI (converted to VGA) video output stopped working on this computer after 9 years of service. This raises question 1:
Is there any way of fixing this? I've tried the usual: triple checked all vga cables & devices through trial & error. Bought a new DVI-VGA adapter. Reset PRAM, PMU, etc. Nothing works. Something is probably damaged, because my KVM switch was not working unless I hot-reseated the vga cable into it, leading to this DVI port, and that is pretty rough stuff.
Question 2 (related):
This dovetails into this: Can I drive a VGA monitor with the s-video output port on this computer. It would take an s-video (male)-to-15-pin-VGA adapter. Has anyone does this? So far, I haven't even found the adapter mentioned anywhere.
Thanks for reading this.

Thanks for the useful feedback, Knucklesmac. I agree. I must have blown something on the logic board -- because I had a faulty old KVM switch that would not switch between computers without some nasty hot-plugging/unplugging the VGA video cables. (wince!). It's like when Dizzy Dean ruined his arm because a line drive hit him in the foot and he readjusted his mechanics around the injury. I take the blame because this has been a great computer, and does not deserve any blame.
If it will help anyone else reading this thread, C2G (née Cables to Go) has some interesting ideas for still getting external video out of this computer:
-USB-to-VGA
http://www.cablestogo.com/product/30545
-Convert s-video or composite video signals to high resolution VGA
http://www.cablestogo.com/product/40971
The price range is $75-$85, which doesn't make horse sense to me for such an old computer -- which has a lot of life in it anyway, because its own 15" monitor is not chopped liver.

No digital video output from XVR-300 in Ultra-45

I am switching from solaris 10/x86 to sparc. I have a new Ultra-45 with XVR-300 graphics adapter. It's running Solaris 10u4. The system was ordered as a standard configuration from the catalog.
The XVR-300 graphics adapter currently produces no digital output. My Sun A1240P0 24" monitor reports no signal on the DVI input. That is, there is no digital output at power on (boot ROM), during Solaris boot (terminal), nor after Solaris finishes booting (X).
The graphics adaptor uses a connector with two video outputs, and comes with a splitter cable with two DVI output connectors. I get no video output on either. The DVI cable I am using is the one that works when connected to the graphics adaptor on the old system.
I added a VGA adapter plug to connector 1 of the splitter cable, and was able to get an analog signal to drive the display via the VGA input connector.
The manuals for the Ultra-45 and for the XVR-300 make no mention of analog vs digital output. They both just say to connect the adapter to the monitor.
Since I can get analog output from the SVR-300, the card is basically working. The DVI cable and the monitor's DVI input work with another system. The only variables are the digital output from the XVR-300 and the splitter cable. (The splitter cable's analog signals work.)
How can I activate digital output and make it the default?

Video Output ALWAYS dictates Audio Out!!??

I have a Black Magic card in my system. To save space on my working monitor, I'm viewing my movie from the output of my Black Magic card on an external monitor. However, the audio is also being sent to this monitor. I'd like to do my mix with my headphones, and not on the crappy monitor speakers, but every time I change the video output, the audio always gets sent to the monitor. I have to watch the video in a window on my monitor to be able to listen over headphones, which is a waste of space. Why can't I control this?
In my audio prefs, audio output is set to built-in output.

Weird, I have both setup, Windows 7 with Lenovo Graphic Driver and Windows Server 2008 R2 with Nvidia Driver, both have audio output.
Try to go to Device Manager to see if there's anything called Nvidia High Definition Audio, for me, I have 4 same devices. If there are unknown devices, install it manually with inf files.
Best Regards
Peter
