Creating a datasource from images taken from MJPEG/JPEG camera
Hy there...
I'm trying to create a JMF Processor from a datasource which should get images from an Video over IP camera (JPEG/MJPEG)...
I used as example: http://java.sun.com/products/java-media/jmf/2.1.1/solutions/JVidCap.html, but is seems that I don't do smth right...
Here are my datasource and my stream classes.

mjpegVioIPGrabber is a class written by me which till now worked perfectly.
I init the processor like this:
public boolean open(Object source) {
try {
logger.log(Level.INFO, "Trying to create processor from " + source.getClass().getName() + ".");
if (source instanceof String)
p = Manager.createProcessor(new MediaLocator((String)source));
else if (source instanceof MediaLocator)
p = Manager.createProcessor((MediaLocator)source);
else {
//p = Manager.createProcessor();
p = Manager.createProcessor((DataSource)source);
if (p == null) {
logger.log(Level.SEVERE, "Unsuported data type to create a Processor");
return false;
} catch (Exception e) {
logger.log(Level.SEVERE, "Failed to create jmfProcessor from given datasource.");
return false;
logger.log(Level.INFO, "Processor created");
p.addControllerListener(this);
p.configure();
if (!waitForState(p.Configured)) {
logger.log(Level.SEVERE, "Failed to configure the processor.");
p.setContentDescriptor(null);
TrackControl tc[] = p.getTrackControls();
if (tc == null) {
logger.log(Level.WARNING, "Failed to obtain track controls from processor.");
return false;
if (this.codecs != null) {
TrackControl videoTrack = null;
for (int i = 0; i < tc.length; i++) {
if (tc.getFormat() instanceof VideoFormat) {
videoTrack = tc[i];
vf = (VideoFormat) videoTrack.getFormat();
break;
if (videoTrack == null) {
logger.log(Level.WARNING, "The input media does not contain a video track.");
return false;
try {
Codec codec[] = { null, null };
videoTrack.setCodecChain(codec);
} catch (UnsupportedPlugInException e) {
logger.log(Level.SEVERE, "The processor does not supprt efects: " + e.toString());
//return false;
p.prefetch();
if (!waitForState(p.Prefetched)) {
logger.log(Level.SEVERE, "Failed to realize the processor");
return false;
if ((vc = p.getVisualComponent()) == null) {
vc = null;
logger.log(Level.SEVERE, "Failed to get processor's Visual Component.");
return false;
if ((cc = p.getControlPanelComponent()) == null) {
cc = null;
logger.log(Level.WARNING, "Failed to get processor's Control Panel Component.");
p.start();
return true;
}and this is also working fine.
I don't get any errors, yet the code does absolutely nothing, and my loggers keep bugging me abut DataSource that is not connected.

Please help. I have to finish the project until this friday, and this is killing me. I have no ideea what's causing this.
I never used JMF until now, and all I did was based on examples.
If you can help please explain as if I were a little baby. Code example would be soooooo apreciated.
OK... Forget what I've told you above.
After reading a little more and understanding some stuff, I managed to pull this out:

}I will not show you the grabber. I've seen a dousin of grabbers on this forum. What I can tell you is, that the two classes must be placed in a package named like this: name1.name2.name3......media.protocl.http (i.e. com.itmc.media.protocol.http).
To test it use: java JMStudio http://cameraaddress (i.e. java JMStudio http://192.168.2.5/now.jpg)

I think this will be more than enough to solve all the problems you have in this type of matter.

When I pushed a button, this pop-up window has to appear. There will be a slide control and a picture from a camera in this window. Is it possible to make appear this windows while main VI Interface continue to run ? How can I do this ? Thank you for your answers.
Cyril.Here you go. This is simple example. Maybe not the best way, I am just
beginner in LV and still not comfortable with data flow that much. I prefer
events, so I would change this to use Event Structures.
When you click on OK button on SliderMain, it opens Slider.vi. Now both
windows are open and you can interact with both. Now if you click on OK
again with Slider.vi open, you run into problems. Only thing I did was
change VI properties of slider.vi, mainly window appearance.

Warranty on the issue of purple spot in images taken from rear camera?
My iPhone 5 have purple spot in images taken from rear camera. I just noticed the issue in my phone today.
I researched online and some people also have the same issue and have their phone replaced in Apple shops.
I don't have any receipt or store warranty card since it was just given to me as a gift in the Philippines last April 2013, I checked the warranty coverage status (https://selfsolve.apple.com/agreementWarrantyDynamic.do) and it still has repair and service coverage.
Im now here in Dubai, and my question is that will Apple Premium Reseller shops here in Dubai honor the said warranty and have my iPhone repaired or replaced?Im now here in Dubai, and my question is that will Apple Premium Reseller shops here in Dubai honor the said warranty and have my iPhone repaired or replaced?
No.
The warranty for an iPhone purchased from an official source in the Philippines will be honored in the Philippines only. -

Can I remove files from "images removed from" dir?
I have some duplicate files on my iMac, including some large videos in a "images removed from xxxxxxx" directory. Can I safely delete these?
Yes, you can delete this additional "images removed from ...." vault, if you do not need this backup of older videos. It contains all photos/videos, that have been backed up in your vault, and have been removed, because they are no longer in your Aperture library. remove this vault only, if you do not want to keep this videos or have other backups of them.
See Frank Caggiano's answer here: Re: Folder labeled "Images Removed from Aperture Vault #1"
But I am puzzled: Why are these vaults on your iMac? Are they on your system drive or on a second internal drive? Vaults are best kept on a drive different from the drive where the library is kept. Otherwise they will be of no use, if the drive should fail and needs to be restored.

A7000 | The images taken from the front facing camera(FFS) (5MP) are mirrored. Is this an issue?
Hello Team,
I just took an image from the FFS off my new A7000 and i noticed that the images are mirrored. Is this a software issue?
I even owned a A6000 but the images from that were proper.
As far as i know mirrored image should be displayed while taking the picture but proper un-mirrored image should be saved.
Please look into this issue.
Here is an image(re-sized) i took from FFS which is reversed/mirrored.
Admin note; picture >100K converted to link. About posting pictures in the forums.Yes i have updated to the latest firmware S141. And yes i am using the default camera app but still the issue exists. Is this a software issue or is it a hardware issue? If its a software issue, then is it possible to fix through future firmware updates? Anyhow i'll take the phone to nearest service center. Can you give me the address for service center in Bangalore(India). Thank you for the reply.

Can final cut pro be used to clean scratches from digital images taken from 8 mm film
I had some 8 mm movies digitally transferred and are now into iMovie. The last batch was water damaged and had the vinegar syndrome problem. (See samples below). I also have a movie that is good quality but moves in and out because the film was bent or curled causing a distorted transfer to 16 mm film.
I would like to clean off the scratches, debris and sharpen the images. I would like to recolorize some of them if possible. Any hope for this or do I wait a few years until the technology becomes available?
Thanks

[email protected]That's a very specialized task that FCP X (nor any other NLE) does out of the box. You'd need something like this- http://www.thepixelfarm.co.uk/product.php?productId=PFClean
Or to be honest it's worth hiring a post house to do this sort of work. Some have automated systems that can run pretty affordable for surprisingly good work. -
How do I remove "read-only" from images transferred from a PC so that I can add keywords?
I switched to a Mac from a PC a year ago and have been using PSE 9 + Organizer with no problems. I transferred all my images from the PC at that time. Now, I want to transition to using Bridge and have been assigning keywords to the newer photos added after I started using the Mac. I am unable to assign keywords to the earlier photos because Bridge says they are read-only. I checked the Apple Get Info on the folders and they are read and write. Any ideas?
the Sharing and Permissions box on the bottom shows I have "custom" and "read & write" access for both pre- and post 9/2010 folders. All others (nobody, staff, everyone) have read only. Of course there is actually only me.
Anne,
It seems related to your OSX. I think you have created a new user account without adding a name (hence Nobody) but I'm a bit guessing in this department.
The default user account folders like pictures and movies have the ability to set to 'custom'. With you as only user and administrator there should preferably only be one user account visible. By default a newly created folder should show 3 options for sharing and permission. User (your name of the user account) Read and Write
Staff: read only
Everyone: Read only.
I have tried deleting "nobody" and "staff" and changing Annie to read and write - all kinds of combinations.
You can only edit users accounts in the system preferences / Accounts. In here is the option for you as administrator to delete and create users accounts. Here is where it is getting a bit difficult because we can't see your set up for the OSX. But if you have to change 'Annie' to read and write and assuming your user account name is Annie it should already have been on read and write. If you are logged in as 'nobody' this should have shown read and write to have access to change metadata.
So you first have to study a bit about user accounts on a Mac and see if you have a correct install. It is not very difficult and you will gain profit from this knowledge.
try the Apple.com support site, for a start here is a link to an article from the Apple Knowledge Base (kb) article about user accounts:
http://support.apple.com/kb/HT3309
Some images have been moved from the original folders so that could be a problem.
Basically you should not have any problem with moving files to whatever folder you want or create on your user account (or to external Disk etc.)
For a start you could create a new main folder in your user account Home folder and call this test or whatever you like except an already existing name. Of course also check if you have read and write permissions for it...
Open Bridge, use the folder panel to select a folder with the problem files. Now scroll through the folder panel and click on the triangle in front of your home folder. This will open the list with nested folders while Bridge content window still keeps its focus on the problem files you first selected. Select a bunch of the problem files from the content panel and use drag and drop to move the files to the newly created folder. Just move the mouse on the folder name and release the files.
If you hold the option (alt) key while dragging there will appear a + - sign and the files are copied to their new location, just use what you think is best for you.
After this action has finished click with your mouse on the newly created folder name in the folder panel and now the files should show in the content panel (if correct also already cached). Check if you are able to change the metadata now.
Most have tags from current and previous Photoshop Elements versions.
That should not be a problem, some info will be readable by Bridge, others not. Some Bridge version even had their own Bridge versions. -

HP Device Manager Issues - Unable to deploy images taken with a particular OS to a different OS
Hi all,
I have been trying to deploy an image taken from a HP T5565 (Thin Client) with the HP ThinPro 4 operating system, to a HP T5565 with the HP ThinPro 3 operating system. Does anyone know if this is possible?
I am also having the same issue when deploying an image taken from a HP T610 - Thin Pro 4 thin clent, to a HP T610 - Thin Pro 3 Thin client.
I take the image by right clicking on the thin client, clicking on 'Send Task', Imaging, then Capture Image.
I deploy images in the same manner, but instead select the image from the Templates window. It works fine for Thin Clients running on the same OS.
I would appreciate any assistance with this!
Regards,
RemoRemo,
You will want to ask this on the HP Enterprise Business Community.
You may need to re-register to post questions as it is a separate forum.

Yellowish image taken with Lumia 920 Amber
I've noticed this very recently. I found that the pictures are yellowish. When I take a photo, it previews it for about 2 sec and then gets saved to Camera Roll. While the previewed image looks good and matches the view, the one getting saved is not the same. I noted that most photos I take are getting blurred and tinted with green and yellow inside Camera Roll. I don't know why this happens as the image looks perfectly on preview. At first, I thought it was a problem with Nokia Camera app but later found that the same happens for the default Camera app too.
To prove this, I took screenshots of preview and made 3 side by side comparisons. They are given below and you can notice the change in colors and the sharpness between the preview and the original. And also the images taken using the front camera makes me a sick yellowish Simpson.
These photos are in Auto Settings.

"Date Created" incorrect in Finder after copying image files from CF reader
Whenever I download image files (by drag and drop copying) from a CF card reader, the 'Date Created' info incorrectly defaults to 'Dec 31, 1903' in the List view of the Finder window.
'Date Created' shows up blank in the File Info window, too. Correct file info does however show up in the copied Meta Data.
I've only been able to transfer correct 'Date Created' info by using Image Capture, which is pretty annoying.
I've tried several cameras, CF cards, USB & FW card readers, and Macs running both Panther and Tiger. Same problem all around. Interestingly, files copy without a problem onto a PC.
I'm a photographer and I need to sort my images by 'Date Created' because I often shoot with two cameras and need to know the chronological order in which photos were taken.
Ideas anybody?

photorec ?
Edit: I see that testdisk and photorec belong to the same package... Still it looks like it should be the right tool for the job; but I might be wrong as I never used it.
Used it a couple of times, my daughter wiped photos from her mobiles memory card by accident .... Linux to the rescue
