Image/BufferedImage to Video Output

Hi,
I'd like to know how to send an Image/BufferedImage to my video card.
In short, i have a java program that displays image thumbnails.
When the user clicks on a thumbnail, i would like the fullsize image to be displayed on a television plugged into my computer's S-Video-out port.
Can anyone tell me how to do this?
thank you

You can use just about any tools for the videos...
The confusing part is that those listed in Lib. mode are sugesting that the dev. mode counterparts arent working.
While they are...
You can apply just all the dev. tools to the video. Aside from brushes etc. SplitTone, Saturation, HSL, curves all working.
Syncing is slow... Do this:
1)Make your adjustments on a captured JPEG frame. The hit Shift+Command + C...
2)Exit Dev. Mode and enter Lib. Mode and select your video
3) Hit shift+command+v to paste the settings.
Much faster than using the sync mode or saving a preset.
It beats me why LR4 doesn't just capture an automatic frame of the footage (From whereever the playhead is) and the when we click Dev. mode just edit on that.
As of now we have to:
0) In Library Mode
1) Goto the Frame we need
2) Click Capture Frame
3) Select the captured frame
4) Switch to develop mode and make settings
5) Exit Develop mode and goto Library mode
6) Select video clip
7) Apply settings...
Even if adobe had strived for it, I dont think they could possible have complicated things any further. They'll get a grammy for this one ;-)
There is SO MUCH room in the library tab.... For ANY video clip... Just put the dev. settings right there for us to mess with. Why only put a few there
with crippled controls...
Why even have TWO MODES... What I hate in Lightroom and always have hated.. Is having to SWITCH from ONE window to the NEXT just to make adjustments with sliders that makes sense
instead of those crippled ones in Library Mode.
We have 2012, fast computers and faster minds. Why should we be crippled like this. Makes absolutely no sense.
Is Lightroom the best software around. IMO = YES.
But I sure hope that LIghtroom WONT be setting what we will come to know as a bar for standard. So much room for improvement. And there has been since V1.
Please --- This time.. Make the app easier to get around. I find myself clicking around MUCH more than I have to.

Video Output for PXI Embedded Real-Time Controller ?

I plan to purchase a PXI Embedded Real-Time Controller for security monitoring.
Is it possible to use the video output of a PXI Controller running RTOS to display messages from a LabVIEW RT application ? According to the documentation, it seems that the use of the video output is only possible for PXI Controllers running Windows XP.
Does it exist a specific application to do this with LabVIEW RT ?
Thanx.
H.L.
Solved!
Go to Solution.

Hi Yann,
The situation seems a bit confusing as in the link you've given above using the local monitor from a pxi labview rt system as the HMI without a pc attached, two messages (here and here) say that it is possible to display an image on the video output of a PXI RT controller using a function of the NI-IMAQ librarey (namely, the IMAQ RT Video Out VI) !
I have the NI-IMAQ library but no PXI controller to test if this solution should work or not
Does anyone have the answer ?
Thanx,

S-video output B&W

Hi,
From time to time I like to connect my PowerBook to TV thorugh S-video (using adapter S-Video to scart) to watch movies with friends etc.
Though, it has been some time (over half a yar) when I last watched a movie on TV that way. Since I know for sure that I have been able to connect my pb to tv via s-video with no problems I can't understand whats wrong now.
Here's the thing. When I connected my PB to a TV now, it shows the picture in black&white on the TV. Anyone know how to get back the colour image? I have the same cable set that I used before to connect to tv (latter is the same one also) without any problems - full colour. So, I think the problem is software-related (maybe os x update).
Can anyone recommend what to do to get the colour back?
cheers,
r. pello
P.S. PB's lcd screen works fine. So, problem only with s-video output colour.
PowerBook G4 (1.67 GHz, 15") Mac OS X (10.4.9) iMac (Summer 2000, 120GB HDD)

Have you checked the resolution/TV type in the Displays preference pane once the TV is connected? If your PB is detecting your TV as PAL rather than NTSC (or vice versa), that could certainly cause a loss of colour like you describe.

How to get a string or byte array representation of an Image/BufferedImage?

I have a java.awt.Image object that I want to transfer to a server application (.NET) through a http post request.
To do that I would like to encode the Image to jpeg format and convert it to a string or byte array to be able to send it in a way that the receiver application (.NET) could handle. So, I've tried to do like this.
private void send(Image image) {
    int width = image.getWidth(null);
    int height = image.getHeight(null);
    try {
        BufferedImage buffImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        ImageIcon imageIcon = new ImageIcon(image);
        ImageObserver observer = imageIcon.getImageObserver();
        buffImage.getGraphics().setColor(new Color(255, 255, 255));
        buffImage.getGraphics().fillRect(0, 0, width, height);
        buffImage.getGraphics().drawImage(imageIcon.getImage(), 0, 0, observer);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        JPEGImageEncoder jpeg = JPEGCodec.createJPEGEncoder(stream);
        jpeg.encode(buffImage);
        URL url = new URL(/* my url... */);
        URLConnection connection = url.openConnection();
        String boundary = "--------" + Long.toHexString(System.currentTimeMillis());
        connection.setRequestProperty("method", "POST");
        connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
        String output = "--" + boundary + "\r\n"
                      + "Content-Disposition: form-data; name=\"myImage\"; filename=\"myFilename.jpg\"\r\n"
                      + "Content-Type: image/jpeg\r\n"
                      + "Content-Transfer-Encoding: base64\r\n\r\n"
                      + new String(stream.toByteArray())
                      + "\r\n--" + boundary + "--\r\n";
        connection.setDoOutput(true);
        connection.getOutputStream().write(output.getBytes());
        connection.connect();
    } catch {
}This code works, but the image I get when I save it from the receiver application is distorted. The width and height is correct, but the content and colors are really weird. I tried to set different image types (first line inside the try-block), and this gave me different distorsions, but no image type gave me the correct image.
Maybe I should say that I can display the original Image object on screen correctly.
I also realized that the Image object is an instance of BufferedImage, so I thought I could skip the first six lines inside the try-block, but that doesn't help. This way I don't have to set the image type in the constructor, but the result still is color distorted.
Any ideas on how to get from an Image/BufferedImage to a string or byte array representation of the image in jpeg format?

Here you go:
private static void send(BufferedImage image) throws Exception
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    ImageIO.write(image, "jpeg", byteArrayOutputStream);
    byte[] imageByteArray = byteArrayOutputStream.toByteArray();
    URL url = new URL("http://<host>:<port>");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    OutputStream outputStream = connection.getOutputStream();
    outputStream.write(imageByteArray, 0, imageByteArray.length);
    outputStream.close();
    connection.connect();
    // alternative to connect is to get & close the input stream
    // connection.getInputStream().close();
}

IMac G5 iSight - Resolution problems when using s-video output.

Good afternoon all.
I have an iMac G5 and the only video output it has is a mini VGA socket. I have used this with a mini VGA to S-Video converter cable from Apple and am getting some odd results.
The Mac is running Leopard 1.5.7 and I'm outputting to a fairly old Panasonic CRT TV.
The problem I find is that when I plug in my mini VGA adaptor to the Mac it reduces the resolution on the Mac screen down to 1024x768 (stretched). The TV outputted TV image looks great, but I can't seem to keep my native resolution of 1440x900 on the Mac display.
If I do go and change the resolution in "displays" in the sys' prefs' then it just seems to keep the 1024x768 resolution on the Mac but this time without stretching it.
Does anyone know how I can keep my Mac at its native resolution of 1440x900 while still outputting to s-video to the TV?
Any and all help will be greatly appreciated.
Thank you again in advance.
Stuart

Hi
I have the same config as you: I have been using it for years to view on my tv dvds or videos from the web.
To my knowledge there is no way to acheive what you wish: when you plug the adaptor in the mac adjust to your output source and its main display (the g5 display) will reflect that with the result that it becomes very difficult to use.
Maybe there is a way to try changing the resolution in a middlle"configuration" which would give an acceptable viewing on the tv as well as on the g5.
Personally I keep plugging and unplugging the adaptor as needed.

Video output from iPod Touch (2nd gen) via AV Component Cable (no audio)

Hi, I'm trying to output a video from my iPod Touch (2nd gen) to my TV via a AV Component Cable.
Unfortunately the audio doesn't work, I'm sure they are all connected into the right places.
The video works, but I get no audio. (And no subtitles when closed caption is on)
Here is a link to an image of the TV connections from ImageShack:
http://img707.imageshack.us/img707/7280/img0204y.jpg
At the top left of the image, are what I assume to be the red and white audio ports, highlighted in red.
I plugged in the red and white audio connectors into those ports.
And towards the bottom are three ports, green, blue and red, also highlighted in red.
I plugged in the green, blue and red connectors into those ports.
I changed the input of the TV to Input 2, I see the video for the movie I'm watching on the TV but no audio. I tried multiple movies.
I've also tried changing the video output from PAL to NTSC and back again, turning Widescreen on and off and turning Closed Captions on and off. I also tried plugging in the red and white audio connectors into the row of ports just below the green/blue/red row, to see if that made any difference, and it didn't.
I tapped the bottom left button of the iPod Touch when plugged in to the TV and playing video and it came up with an option that was selected called ~"Audio Source: English (Stereo)"
Any idea's? Thanks.

Resolved... ThankYou

Video output quality worse than AppleTv 1

Anyone else who owns an atv1 found video looks worse?
I'm not talking about actual video playback but the video output on 2
AppleTV1 looked great through my plasma even though it's not full HD
1080p over hdmi on 1 scaled by the plasma consistently looked best, with crisp but smooth edges to text and GUI.
Atv2 720p over hdmi looks consistently worse - it all looks oversharpened and over contrasty, with text in particular looking very jagged as well as the spinning timer wheel looking pixellated now
Watching a slideshow there seemed to be visible artefacts as some images moved or scaled whereas atv1 just looked silky smooth
Maybe the current GUI text and icons are not as smooth, maybe less antialiasing, poorer quality gpu
Maybe my plasma downscales 720p worse than 1080p - I need to check on the full HD set in another room but first impressions are not that good
Video playback seems strangely artificial too, almost as though the frame rate has been sped up slightly
Weird as the set should handle 50/60Hz without issue

So a few days in it's growing on me.
There's definitely something different about menu graphics but actual video quality for playback is excellent though I'm not sure it's not dropping/catching up frames at times.
I've watched some HD movie trailers and they look excellent.
Video navigation is considerably improved over ATV1, with FF / RW actually working reasonably well when they didn't before over the same connection. Changing chapters gives immediate starts and buffering seems considerably quicker - at least some of this must be due to newer hardware.
I don't like the top level menu much and preferred the older system but you can pretty much stay in Computers to watch own content.
Video playlists don't work properly which is poor but it took ages to get them enabled on ATV1.
There are many glitches but hopefully they'll get ironed out over time.

Video output via cable - incompatible with video p...

I find that although video output via cable from the Nokia 6220 classic (and I presume other Nokia phones) works fine with TV sets, I haven't found a single video projector that accepts the output and is able to project it. The projectors typically search their video inputs and should recognise the composite video input, but instead they just keep searching and are never able to recognise or project the video.
Is there something unusual about the video signal output from it so as not to be accepted as composite video by video projectors?

iphone4 and composite and component cable don't support mirror so they
only display images when an supported app is being used like youtube or the video app and the likes
use both the composite and the component cable with my iphone4 on 5.1 and both works fine
so do my ipod touch with 5.1 and ipad2 with 5.1

External Video Output

Hi,
I'm having trouble sending the image from Color to an external monitor for accurate color balancing. When I go to Video Output pop up menu in the set up preferences, the only option they let me click is "Disabled". It's an HD image to a Sony HDV deck which converts it down to a SD monitor, but IO can do it in Final Cut, so I'm not sure why I can't do it in Color. Any suggestions?
Message was edited by: jesterhead

You'll need a third party i/o device to handle the conversion for you. If you have a MacPro, the Black Magic Intensity cards (at the low end) up to the AJA Kona series cards (at the upper end) will work. Mid way are the Matrox MXO series of external boxes - most of which will work with an expresscard34 capable laptop as well.

Mailbox effect between shared and quicktime video output

Here are some screenshots from a movie I'm making. You'll see the kid doing the limbo in the clip at the centre of the top image is mailboxed with black top and bottom. I've added some type to the frame (lower portion of bottom screenshot) and it looks like it'll fall outside the image, but when I export the movie as a medium shared video, it turns out fine (upper part of bottom screenshot). Make sense? I can't figure out why this is happening and where the edges of my frame are. The problem gets serious if I export to Qucktime because the mailbox effect shows while it doesn't show in the medium shared video output.
Any advice appreciated.

Hi this worked for me... After you've changed the stuff within the browser close it out completely, Open the actual QuickTime on your PC edit-preferences then you will see both player and QuickTime separately. You need to uncheck automatically start play in both preferences, in the second one it has a browser tab when you click that the default is set checked for automatically play in browser uncheck that go through each tab in both preferences and make sure autoplay is not enabled anywhere, Good luck Rhondar35

mpv doesn't crash, it just falls back to software decoding and gives me a grey screen when it's not fullscreen, and when it's fullscreen it tears a lot and flashes random grey stripes everywhere - sound still works fine. Any ideas on what can be at fault here? The only video output that gives me an OK image without tearing or anything else is x11, but it's really slow.

Now try vainfo again. Instead of "Splitted-Desktop Systems XvBA backend for VA-API - 0.8.0" it should say "AMD MMD 1.0" or something like that.
Thanks, now VA-API at least gives me an output - but the video just flashes in fullscreen. I think another thing to notice here is that the video only plays correctly (gives me an output), if I play it on monitor 1 (I use three monitors) - but I can't get rid of the screen flashing.
EDIT: Fullscreen only flashes when I use mpv, with smplayer (+mpv) it works ok - but it lags from time to time. mplayer-vaapi won't give me a smooth playback either with -vo and -va as vaapi, and the screen also flashes when I'm using it.
Any idea on what's wrong? Is it my use of three monitors? This is really, really annoying.

Adobe Media Encoder All Video Output 'White'

Hi all,
I am attempting to use Adobe Media Encoder to export a QT h264 optimized for upload to facebook from a QT file exported 'Same as Source' from Avid MC 5.0.3, whic would be 1080i60 1920x1080. The source file playsback correctly in QT player or VLC, but even the output preview screen in AME shows only a white image.
I've also tried converting a completely different QT file created in Premiere Pro, with the same white video output issue. I've tried opening/closing AME with no luck, but hte last time I used it I didn't have any problems and was able to produce the desired end result.
Thoughts?
Thanks for your input,
Lindsay

Hi,
Yes you are correct in assuming the two software packages are on different machines. I am using Premire Pro CS5 5.0 and Avid Nitris DX MC 5.0.3 And no, I do not believe I have installed any Avid Codecs. I just followed your link, will download and do so now. I'm assuming this will fix the bug, but if not I will let you know.
Thanks for your help!

ATV3 no video output

So, my ATV3 has been working fantastic for about 10 months streaming from my Plex to my Panasonic 50" TV, when suddenly 2 nights ago in the middle of a movie it appeared to crash with the screen going blank or black. The light was still on in the front, but no video output on screen period.
I cycled the unit several times by removing and reconnecting the power to no avail.
So, I bought the unit into work and plugged into one of our HDMI LCD 1080 screen and bang, I get picture, so thinking all good, I took it home. Oops, no video again, so I plugged the work ATV3 into the same cables and WOW, all good.
Back at work today and yes, the home ATV3 appears to work fine, but wont display a picture on my home TV?!...Its at 5.3 software (6105) and the work ATV3 is on 6.0.
There is a story with the work one, it had updated to the latest version several weeks ago, and when I had taken it home to check Plex was running on it, it too wouldnt display on my home TV, so I took it to cousins house with same brand TV and same story, NO display. Took it to neighbour with cheap TV and it worked.
Long story, I got Apple to swap my work ATV3 for a replacement which hadnt updated to latest version and yes, it worked at home etc....Thinking that it was a software issue, I have kept my home ATV3 from updating, however now that it has crashed, Icant get that working either, only the replaced work unit works..
same cables etc...yet no image...
Any ideas?

Try replacing the hdmi cable or plugging the existing hdmi cable into a different hdmi hole in the TV..
One of those might produce a good result.
Typical reasons will be electronics will get worse over time, and will introduce noise, performace issues.
But that is a best guess. go try and see how you go.

Bad Video Output -- with example

I've seen several people complain about the poor quality of the video output from FCE and this is something I've experienced myself so I'd like to find a solution. When people make these posts about quality, the usual response is that there must be some sort of user error or bad input. If that's the case, then the "correct" way to convert video remains a mystery to many of us. Let's shine some light on that dark corner...
To wit, here's a sample screen capture showing the original .MOV file from my camera on the left and the output of FCE on the right:
http://www.photo.net/photodb/photo?photo_id=5215575
Clearly something went awry in the conversion process, but it's nothing I've done explicitly. Perhaps you can help me identify what did go wrong, why it went wrong, and how to avoid it in the future.
First some details.
The original input file (on the left) came from a Canon SD700-IS camera and was put through a File|Save As process in Quicktime Pro to make it a proper .MOV file. Viewing the video clip within FCE, it looks just as good as the source version.
But once I've exported the entire sequence to a file, the video looks kinda crappy -- like in the frame on the right. Part of the issue is stretching the source 640x480 to NTSC 720x480, but beyond that it looks like the compression was done very poorly. Things are just a LOT blurrier and there's very little contrast.
The bottom line is -- what are some of us just simply not seeing.
Cheers,
ALF
Powermac Dual G5 2.3Ghz Mac OS X (10.4.4)

Hopefully this helps explain my understanding better...
I'm familiar with MJPG, but the video is not MJPG when I put it into FCE. The picture on the left has already been converted by Quicktime.
While MJPG is a series of JPG images and each individual JPG image is compressed slightly (I don't do lots of compression in the camera), the point I was making is that each of these frames is a key frame. When QT or FCE or anything else converts such a file it has a WEALTH of information to use and therefore image quality shouldn't degrade.
One of the things I don't understand is the insistence that upsampling is occurring. While FCE may indeed be upsampling, it SHOULD NOT BE because I've centered the input video within the 720x480 DV frame. No scaling need occur.
This is akin to making something smaller than 720x480 in After Effects, for example, and importing to FCE as an overlay for something. There should be no quality degradtion because that's not being scaled to 720x480 either -- it's just a small part of the screen.
There also isn't an issue with frame rate because, as I mentioned, the source video is 30fps. Any suggestion otherwise is assuming 15fps for the source video, which is incorrect.
The only thing that leaves as a factor is interlacing -- the source video is most certainly not interlaced. So as I understand things right now, the loss in video quality I've seen is due to artifacts introduced by interlacing and delta-compression. Because I've seen lots of example of delta compression which don't look this bad, I'm hoping there's some way I can tweak the amount of compression or something. Not much I can do about interlacing, though.
As to the camcorder issue, the reason I said it's not germane is because it's the data that's important rather than where it came from. I could just as easily get a 640x480 Quicktime, AVI, or MPEG file as source and see the same type of degradation (I've done it).
The problem is how FCE treats 640x480 (or anything less than 720x480) video. By default it does indeed upscale to fill the full DV frame. But it also provides the ability to drop smaller video onto part of the frame as well as the ability to scale video within the frame.
So if FCE is putting my 640x480 video through a scaling process to place it as a centered 640x480 image in the 720x480 frame, and scaling that again for DVD out put, then yeah I can see where degradation would occur. I just don't believe it should be doing that first scaling.
I also don't understand why interlacing would cause so much degradation, but as has been said it could be the combination of that and the (unnecessary) scaling.

Premiere Pro CS6 - Video Output (GPU) bad quality...

Hi,
I have a question about Adobe Premiere Pro CS6...
I have installed the Trial-Version and use a BM Intensity Pro to output Full-HD 1080i (50, Interlace) trough HDMI Video-Output...
The Video-Output works correctly, but if I enable the "GPU"-Acceleration (CUDA), and scale or transform a Video (for example a 3D-Transformation) the Quality of the transforming is very bad! (jerky, not "smooth", Interlace-Lines etc...)
If I deactivate the GPU-Acceleration (Software only Mode), everything is smooth and looks good!
Also if I render the Timeline, all tranformations are also smooth, only the Realtime GPU Rendering looks very bad....
What can I do?

Hi :-)
I have tested it now with another Grafikcard!
And it is exactly the same problem
I have found out, that the GPU makes a delay, after a few seconds the Transformation looks smooth/bicubic!
But on relatime-Playback its bad...
My English isnt very good, so I have some problems to describe what I mean...
If you stop the playback, it takes 2 Sekonds and then the image looks good!
But dureing the playback its very bad quality, false Interlace-Lines etc...
here are two screenshots:
