JMF Read While Writing

Hello, my fellow programmers
I have one delicate problem with JMF. I develop video streaming from file. So one Thread is reserved for creating JMF player
player=Manager.createPlayer(Manager.createDataSource(new MediaLocator(f.toURI().toURL())));
player.addControllerListener(this);
player.start(); //AUTOSTARTThe second Thread is reserved for sending UDP packages. The main question is how to read packages that has been transmited while file isn't completed- fileWriter.close();
I want to play JMF player over not yet completely transmitter video file.
Thanks in advance!

You're having problems because you're not using JMF's functionality correctly.
First, if you're wanting to stream JMF, you should be using either a DataSink or the RTPManager interface to handle RTP streaming.

Second, if you're wanting to save a JMF file you're receiving, you should be using a DataSink.

Reading while Writing on SSDs vs HDDs

So, I've always heard that reading and writing to an HDD is not good, as it slows down the whole process (this is in video rendering for Premiere Pro).
So, I know that SSDs are quite a bit different. I'm assuming that reading and writing occurring on 1 SSD during rendering isn't going to be nearly as much of a problem as it would be happening on 1 HDD. However, I'm unsure of this. Am I correct in my assumption? If not, what kind of performance degradation might occur, would it be noteworthy, and how comparable would it be to that of an HDD?

Yes, in addition.....current high quality SATA III SSDs that have the best controllers in them for video editing, ( like the Crucial M550, or, the more expensive Samsung 850pro), will not suffer from "fill degradation"....losing performance as the drives becomes more full. Also, the RELIABILITY ....especially on the Samsung 850 Pro....is WAY higher for the SSDs, than mechanical spinning drives.....allowing those quality SSDs to be considered for RAID 0 usage with a much lower risk.
What you are getting at is the nature of the SATA interface itself......it is a "half-duplex" interface, which means it CANNOT write while READING...and vice-versa. It's like an old walkie-talkie radio....when you push the button to speak and transmit...you cannot RECEIVE anything ,until you let the button go. So, YES ,that "half-duplex" handicap is still there.....BUT, SSDs reduce its effect with their MUCH faster read and write speeds AND their drastically lower "latency", as Eric has said.
There ARE places to connect storage devices, especially on the new Haswell E X 99 motherboards, which are "full duplex"...allowing reading and writing at the SAME TIME. However, the storage devices to take advantage of this higher speed and full duplex connection currently are much more expensive than SATA devices. M.2, , SATA "Express", and PCI card storage devices can be used.....but, currently at high expense and limited capacity.
With X99...one option is to take advantage of the huge amount of SATA !!! ports on the motherboard and just create RAID 0 with SSDs for storage..or, use cheaper HDDs, with a large "enterprise level" 7200rpm HDD to BACK UP the HDD RAID0 array !

Disc error -43 occurred while reading or writing to a scratch disk.

"Disc error -43 occurred while reading or writing to a scratch disk. Sorry, but this error is unrecoverable."
What does this mean, and how can I fix it?
I assume it affecting my performance if PS is not able to write to the scratch disc???
I get the error every time I shut down Photoshop.
Attached are my settings.

It means that the OS says there was an error with your hard disk.
You need to check the disk for problems, and make sure you have your data backed up before continuing.
It could be a one time thing (especially if the SMART system remapped the bad block), but could also be an indication of serious problems with the disk if it recurrs.

Very slow painting while reading and writing doubles into file

for 15MB length file i = 7662080
for 50MB length file i = 12414368
Part of Code for writing into file follows like this:
try{
fos = new FileOutputStream("Angel.txt");
File f = new File("Angel.txt");
 if(f.length() >=4)
 f.delete();
fos = new FileOutputStream("Angel.txt");
dos = new DataOutputStream(new BufferedOutputStream(fos,1000000));
int x=0;
double y_last, y_new;
for(int j=0 ;j<i ;j++)
if(some condition)
y_new = ....;
try{
//previously in vectors
y_last = y_new;
vect.add(new Line2D.Double(x, y_last, x, y_new)_;
dos.writeDouble(y_new);
 }catch(Exception e){System.out.println(e);}
dos.close();
fos.close();
x++;
}catch(Exception excp){System.out.println(excp);}
part of code for reading from file follows like this:
public void paint(Graphics g)
try{
 double y1, y2 =0;
 Line2D.Double doub;
 raf = new RandomAccessFile("Angel.txt","r");
 dis = new DataInputStream(new BufferedInputStream(new FileInputStream(raf.getFD(),1000000)));
 raf.seek((rect.x*8));
 for (int i = 0/any value; (i < value as per choice); i++)
 g2.setStroke(new BasicStroke(0)); //2
 y1 = y2;
 y2 =dis.readDouble();
 doub=new Line2D.Double(i,y1,i,y2);
 g2.draw(doub);
dis.close();
 raf.close();
}catch(Exception excp){System.out.println(excp);}
I tried using Object Streams but NotSerializable Exception is thrown as Line2D.Double objects
are not serialized.
Any idea to make reading and writing into file specially from MB files faster is appreciated.

Why are you reading in the file in the paint method ?
Create your data once before painting.
I think you should explain what is your goal and what behavior you want.

Access denied error while writing a file to the file system - myfileupload.saveas() throws system.unauthorizedexception

hi,
as part of my requirement , i have to perform read and write operations of few files [ using the file upload control in my custom visual web part] and on submit button click.
but while writing these files - with the help of fileupload control - and when i use myfileupload.saveas(mylocation);
- i am saving these files into my D:\ drive of my server , where i am executing my code -, am getting access denied error.
it throws system.unauthorizedexception.
i have given full control on that folder where i was trying to store my attached files. and also after following asp.net forums,
i have added iusr group added and performed all those steps such that, the file is saved in my D:\ drive.
but unfortunately that didnt happen.
also
a) i am trying the code with runwithelevatedprivileges(delegate() ) code
b) shared the drive within the d :drive where i want o save the files.
c) given the full privieleges for the app pool identity- in my case , its
network service.
the other strange thing is that, the same code works perfectly in other machine, where the same sp, vs 2012 etc were installed .
would like to know, any other changes/ steps i need to make it on this server, where i am getting the error.
help is appreciated!

Hi Friends,
I have gone through scores of examples and i am failing to understand the right thing to be done to copy a file from one directory to another. Here is my class...So let's see... C:\GetMe1 is a directory on your machine, right? And this is what you are doing with that directory:
public static void copyFiles(File src, File dest) throws IOException
// dest is a 'File' object but represents the C:\GetMe1 directory, right?
fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
BTW, this is awful:
catch (IOException e)
IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
}1) You're hiding the original IOException and replacing it with your own? For what good purpose?
2) Even if you had a good reason to do that, this would be simpler and better:
throw new IOException("your custom message goes here", e);
rather than explicitly invokign initCause and setStackTrace. Yuck!

Facebook timed out while writing a post. Any attempt to open FB, now shows post that was in progress and immediately crashes app. Cannot clear timed out item. Have power failed and done warm reboot on iPad.   Is Delete/Reinstall only option?

Was writing post, as part of sharing article from my newsfeed.   While writing, Facebook timed out. Display cleared. App recycled and returned to newsfeed. This has happened previously and for all purposes, the original post, since it had never been "loaded" onto FB servers effectively was deleted from iPad memory. That appeared to be the case yesterday; as I was able to continue reading, sharing and commenting on other articles.
Later, as I was shutting iPad down for the night, scrolled through open Apps and discovered the original FB window was still "open" I'd apparently been working on a 2nd or mirror version of the app. Attempting to access the original page; it opens, but I am unable to "interact" with the display/app, pressing "cancel" on my original post has no effect. Within 5-6 seconds FB crashes.
I power failed the iPad, left it over night and today am encountering the same problem.   Tapping FB icon, brings up the post that was timed out. It displays for 2-3 seconds max, then original article and partial post disappear. Newsfeed appears to be loading as that and contact columns are visible in light font indicating they are preparing to load.   2-3 seconds, that vanishes. Am left with blue header band, spinning wheel indicating it is trying to communicate or process something.   2-3 seconds and then screen goes black and I'm returned to my app desktop.
If I immediately tap icon to reopen I get white screen, with blue header band.   2-3 seconds, black screen, back to app desktop.   If I wait 2 minutes, I get the full shared article, partial post as described above. I've confirmed in the problem log that this is failing in Thread 0 and showing up as system crash.
Based on feedback to somewhat similar FB problem I found in forum; in addition to doing power fail. I also did warm reboot (Home and Sleep keys) in hope app would reboot along with ios. No change.
At this point, I'm assuming my only viable option is to delete the app and reinstall it from App Store. Easy enough to accomplish. But wanted to see if there were any other recommendations, or whether anyone else has experienced a similar failure with FaceBook.
Thanks for your assistance.

Error while writing wsdl file

Hi,
i' m working on jdeveloper 10.1.3.1.0 and when i want to add a partner link to my BPEL project i get 'error while writing wsdl file' 'exception null' error then i couldn't create file.
so how can i solve this problem?
HELP:)

Once the wrapper procedure is created by the adapter, the adapter does a second search to obtain the information about the wrapper (i.e. parameters, their data types, etc.). What's likely happening here is that the wrapper is getting created, but the adapter can't find it. The XSD is based on the wrapper, so if it can't be found, then no XSD can be generated. Try removing the existing wrapper package or choose that option in the wizard when it generates a new one.

We are running FM version 7.2b144 on MS Win xp Pro (32 bit), and I did not notice this until service pack 3 was installed. I believe I have found a work around to the situation and another contributing cause. If graphic files are placed directly in an anchored frame instead of importing by reference, the file somehow becomes misplaced. If you right click the graphic and open the Object Properties dialog box, and see the phrase "no referenced file" below Main Editor: Referenced File: in the lower left hand corner, this has happened. I found if I removed all graphics files without references and imported them by reference, the source file may then be properly saved. I am also using a program called CCleaner, which removes cookies, temp files, browsing history and the like from a system. If the program settings are chosen too aggressively, and the application runs when FM has a file open, this same error will occur, even if all files are referenced properly. I don't know if SP3 has some similar application which is now running in the background and causing this.
To summarize, if you want to retain SP3, I have eliminated this error by confirming the links to referenced graphics files and avoiding using 3rd party "cleaners" while FM is open.

That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

I can no longer (since upgrading to the latest firefox) open up multiple tabs of the same page (something I need to be able to do when emailing and referencing multiple emails while writing one email). The only option it gives me is to 'switch to tab'.

Question
I can no longer (since upgrading to the latest firefox) open up multiple tabs of the same page (something I need to be able to do when emailing and referencing multiple emails while writing one email). The only option it gives me is to 'switch to tab'.

I'll try to make this clear. I USED to be able to left click on a hyper link and the hyper link would open in a NEW tab. Now for some unknown reason the hyper link by default opens in the same tab (window). I have to right click the hyper link in order for it to open in a NEW tab. (Yes, my 'tools'> 'options'> 'tabs' are set to "open new windows in a new tab." (Please no answers telling me to get rid of the Ask toolbar because I don't have one.) Thank you.
