Skype H.264 input stream (Logitech C920)

Hi,
does skype for linux support the webcam encoded H.264 stream as video input? (to avoid CPU bottleneck) I'm considering to get a logitech C920 for HD video.
Thx.

OK, in FP11 Beta 2 it appears you have fixed this bug (aspect ratio messed up when switching from 320x240 to 640x480), but now you've reintroduced the Camera.activityLevel bug again. It only reports 0 and 100, this was fixed in Beta 1.
To summarize:
FP 11 release
Camera.activityLevel - broken, only reports 0 and 100
Changing camera size from 320x240 to 640x480 - works
FP 11.2 beta 1
Camera.activityLevel - fixed
Changing camera size from 320x240 to 640x480 - broken, turns video from color to black and white and has a strange aspect ratio
FP 11.2 beta 2
Camera.activityLevel - broken, only reports 0 and 100
Changing camera size from 320x240 to 640x480 - works
Hopefully you'll have everything working in beta 3.
Do I need to submit a bug report for the Camera.activityLevel bug in FP 11.2 Beta 2?

Audio Out of Sync using Logitech C920

Hello.
I am shooting in 720p with my Logitech C920 the sound is fine as raw file and in windows movie maker even after saving.
When I open it with Premiere it's out of sync before creating track and after saving. I am new(using the trial) and I am new to having all these crazy settings and my guess is I messed something up perhaps. Everything was working fine the other day.
I have just been using the default settings when I make a new project. I save android 720 H.264
I have attached a screenshot of the file details if that helps. Thank you so much I really hope I can fix this as I don't want to re-film or use another program(WMM sucks lol).

I couldn't find an edit button but also wanted to add.
I cleared the media cache from settings so the files had to conform again. I dragged file to new item as well to no avail.
For other stuff you may need:
What version of Premiere Pro? Include the minor version number (e.g., Premiere Pro CS5.5 with the 5.5.2 update). 8.1 I am using the trial
Have you installed the recent updates? (If not, you should. They fix a lot of problems.) Yes
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac". Windows 7
What kind(s) of source footage? When telling about your source footage, tell us about the codecs, not just the container types. For example, "H.264 in a .mov container", not just "QuickTime". H.264 MP4 using Logitech C920 webcam
If you are getting error message(s), what is the full text of the error message(s)? None.
What were you doing when the problem occurred? Dragged file in and watched it.
Has this ever worked before? Yes
What other software are you running? Nothing
Do you have any third-party effects or codecs installed? I think I have FFDshow and Divx, I am unsure about these things, maybe I need to fix them?
Tell us about your computer hardware. Be especially certain to tell us about third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU). ?
Are you using Mercury Playback Engine GPU Acceleration? No idea, how do I check?
Does the problem only happen with your final output, with previews, or both? Both
Here is more details about the video also. Hope this helps let me know if I need to give more info!

Logitech C920 and Skype Video Calls

So, the Logitech C920 I have worked before with Skype video calls with no problems. But after this new update, it doesn't detect the web cam anymore. I've googled, searched this forum, searched reddit and every possible form of help to only still not detect the web cam.
I've used 6.22, 6.18, and right now I'm on 6.14 and it still won't be detected. I've tried every USB 2.0 and USB 3.0 port I have on my rig.
Now before someone tells me it's the web cam that's broken, the web cam works on Logitech's program, it works on twitch, it works on Microsoft's program as well. All drivers are up-to-date as well.
Completely frustrated with this problem and I was wondering if posting it would be of any help.
I am on Windows 8.1 Pro 64-bit as well.
Solved!

Hi,
Im having a similar issue. Logitech c920 no picture in SKYPE. Other apps are OK and SKYPE titles my webcam but it just a blank screen with spinning wheel in setting. Sound is OK.
Im running Windows 7 64bit. I have uninstalled SKYPE and updated the drivers ( AMD Catalyst to 14.2 and also tested beta 15.4 ) with no change.
Any help would be appreciated

Connectivity Issues regarding Logitech C920 Webcam and Windows 8.1

Recently, I purchased a Logitech C920 webcam. Successfully downloaded Skype (most recent version 77.85) and passed the microphone and speaker test. My current version of Windows is 8.1 (64-bit) The speaker and microphone application for Skype is online and passed. However, the webcam application for Skype does not connect. In addition, the Windows Camera application for Windows 8.1 successfully works. All three capabilities of the Windows camera application works: sound, recording and camera connectivity. I was able to sucessfully to download the latest version of the Logitech Webcam Software for the HD Pro Webcam C920. After rebooting Windows, I was able to load the Logitech C920 icon and corresponding executable to the desktop. However, all webchat applications besides the Windows supplied Camera application have issues with the Webcam connectivity:
Yahoo Messenger
Skype
Paltalk
Logitech
After downloading the Logitech executable, The Windows 8.1 is still unable to detect C920 webcam. With the Logitech Webcam Software, it just doesn't detect it at all. The whole thing is just black or blank. I know the camera is functional though, because it works perfectly fine in the Windows 8.1 Camera app. Any assistance and help regarding this issue will be greatly appreciated.

Hello @lmhjcr , Welcome back to the Forums! I hope you enjoy your experience
I noticed your posts about the error message "the device installation is incomplete" you are seeing when you attempt to install your printer on Windows 8.1. I am going to share some of my suggestions with you.
1. Check that Internet Explorer pop-up blockers are turned off before downloading the installer
Internet Explorer Pop-up Blocker: How do I turn off Pop-up Blocker?
Try to install
2. If you're running McAfee Live Safe or any other firewall, please temporarily disable the "real time scanning".
How to disable realtime scans
Try the install
3. Go to the start screen (you may also press the windows key + R to open the run box) and type %WINDIR% this should show the windows folder.
Click on the folder and scroll until you see files. Look for a filed named "HPWINS*.DAT" (the * is for a number that varies) remove this file and try the installation.
Try the install

Disable Logitech c920 microphone messages

I am using a Logitech c920 webcam that has a builtin microphone, using headset instead. I keep getting the same two messages whenever I log into skype.
http://puu.sh/hu7iT/787773a271.png
http://puu.sh/hu8iy/69e89475f5.png
I don't have a problem using the webcam, it works fine. My problem is with the continual popup of these messages whenever I log into skype.
I have messed around in the settings a few times and nothing I do besides unplugging the thing stops these messages from popping up.
How do I disable these messages?

There are specific drivers for the C920 with VIsta. Download them: http://www.logitech.com/en-us/support/hd-pro-webcam-c920?section=downloads&bit=&osid=13
Install them.
I have the C920 (it's a rockin' cam!) and it works with my Vista SP2 machine... BUT... I had to install the software from that link first.

How to take advantage of H.264 video streaming of webcam BCC950

We used flex 4.6 to develop an web app using Logitech webcam of BCC950, We used Graphedit of Directdraw to know BCC950 has pin 0 to support i320,RGB24,and mjpg stream, and pin 3 to support H.264 stream. We also set h264videostreamingsettings in as code to ask for H.264 data directly from the webcam, but from the CPU consuming we can judge flash player only fetch pin 0 uncompressed data instead of H.264 data directly. We need to take advantage of BCC950 H.264 support to get webcam hardware compressed H.264 streaming data to avoid compression by CPU/software. As we know flash does not give programmers choice to define the pin to get data, then what we need to do to make sure we can get H.264 video stream from the webcam directly? thanks. Henry

...well I did follow that article on playing an h264/mpeg4
video in flash. It works well, but how would you add playback
controls?
FLVPlayback component only allows you to source an FLV video
not h264/mpeg4.
This is probably a simple as3 answer...but I am not
knowledgeable on as3 to know what code to add.
Any suggests or direction that I should look would be great.
In the meantime I am researching actionscript 3 to find and anwer.

How do I return an input stream from a text file

Suppose there's a class with methods..
one of the methods is something like..
public int value() and has a return statement at the end obviously for returning an int value..
Another method reads a text file and creates an input stream..
Scanner data = new Scanner(new File(input.next()));
I want to return the data when I do a call to this method, but I'm not sure what the method heading would look like..

When using URLConnection read input stream error

hi,
In my applet I build a URLConnection, it connect a jsp file. In my jsp file I refer to a javaBean. I send two objects of request and response in jsp to javaBean. In javabean return output stream to URLConnect. At that time a error happened.WHY???(Applet-JSP-JAVABean)
Thanks.
My main code:
APPLET:(TestApplet)
URL url = new URL("http://210.0.8.120/jsp/test.jsp";
URLConnection con;
con = url .openConnection();
con = servlet.openConnection();
con.setDoInput( true );
con.setDoOutput( true );
con.setUseCaches( false );
con.setRequestProperty( "Content-Type","text/plain" );
con.setAllowUserInteraction(false);
ObjectOutputStream out;
out = new ObjectOutputStream(con.getOutputStream());
Serializable[] data ={"test"};
out.writeObject( data );
out.flush();
out.close();
//until here are all rigth
ObjectInputStream in = new ObjectInputStream( con.getInputStream() );//happened error
JSP:
TestBean testBean = new TestBean ();
testBean .execute(request, response);
JAVABEAN:
public void execute( HttpServletRequest request,
HttpServletResponse response )
ObjectInputStream in = new ObjectInputStream( request.getInputStream() );
String direct = (String) in.readObject();
System.out.prinltn("direct");
ObjectOutputStream out = new ObjectOutputStream( response.getOutputStream() );
SerializableSerializable[] data ={"answer"};
out.writeObject( data );
out.flush();
out.close();
Error detail:
java.io.StreamCorruptedException: invalid stream header

     at java.io.ObjectInputStream.<init>(ObjectInputStream.java:251)
     at TestApplet.postObjects(TestApplet.java:172)

you have to pay attention to the sequence of opening the streams.
The following example is: client sends a string to server, and servlet sends a response string back.
client side:
         URL url = new URL( "http://152.8.113.149:8080/conn/servlet/test" );
         URLConnection conn = url.openConnection();
         System.out.println( "conn: " + conn );
         conn.setDoOutput( true );
         conn.setDoInput( true );
         conn.setUseCaches( false );
         conn.setDefaultUseCaches (false);
         // send out a string
         OutputStream out = conn.getOutputStream();
         ObjectOutputStream oOut = new ObjectOutputStream( out );
         oOut.writeObject( strSrc );
         // receive a string
         InputStream in = conn.getInputStream();
         ObjectInputStream oIn = new ObjectInputStream( in );
         String strDes = (String)oIn.readObject();server side
         // open output stream
         OutputStream out = res.getOutputStream();
         ObjectOutputStream oOut = new ObjectOutputStream( out );
         // open input stream and read from client
         InputStream in = req.getInputStream();
         ObjectInputStream oIn = new ObjectInputStream( in );
         String s = (String)oIn.readObject();
         System.out.println( s );
         // write to client
         oOut.writeObject( s + " back" ); I have the complete example at http://152.8.113.149/samples/app_servlet.html

Error while executing SSIS package - Error: 4014, Severity:20, State: 11. A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: 109, output error: 0)

Hi,
We are getting the following error when running our SSIS packages on Microsoft SQL Server 2012 R2 on Windows Server 2008 R2 SP1:
Error: 4014, Severity:20, State: 11. A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: 109, output error: 0)
SQL Server Data Tools and SQL Server Database Engine reside on the same server.
We tried the following:
Disabling TCP Chimney Offload
Installed Windows Server 2008 SP1
Splitting our SSIS code into multiple steps so it is not all one large continuous operation
The error occurs during a BulkDataLoad task.
Other options we are investigating with the engineering team (out-sourced, so delayed responses):
Firewall configurations (everything is local, so this should not make a difference)
Disabling the anti-virus scanner
Are there other things we can try?
Any insight is greatly appreciated.
Thanks!

Hi HenryKwan,
Based on the current information, the issue can be caused by many reasons. Please refer to the following tips:
Install the latest hotfix based on your SQL Server version. Ps: there is no SQL Server 2012 R2 version.
Change the MaxConcurrentExecutables property from -1 to another one based on the MAXDOP. For example, 8.
Set "RetainSameConnection" Property to FALSE on the all the connection managers.
Reference:
https://connect.microsoft.com/SQLServer/feedback/details/774370/ssis-packages-abort-with-unexpected-termination-message
If the issue is still existed, as Jakub suggested, please provide us more information about this issue.
Thanks,

Hi,
Don't know which of this factors solved the problem:
1. Error server:
AIX 5.2
jdk 1.3.17 (minimum from docu: 1.3.11)
$ORACLE_HOME wasn't in the begining of $PATH
2. success server:
AIX 5.3
jdk 1.4.02
$ORACLE_HOME is now in the begining of $PATH

SocketException during reads - JVM_recv in socket input stream read

I am getting a SocketException when a Java applet talks to our
WebLogic 7.0 server. The catch is that it only occurs at one site
(that has very high T1 utilization, although latency is only ~60 ms)
Our setup is such that the calls hit an Alteon load balancer, which
then sends the request out to one of 4 IIS clustered servers, where it
then is sent to one of 2 WL clustered servers. I figured latency
would be the cause, but on IIS and on WL, the timeouts are set to
several hundred seconds, so I am not quite seeing where the connection
is being reset. To be honest, I really don't know if it is WL that is
killing the connection, as nothing abnormal shows up in the WL log. I
have seen similar problems in this group, though, although the stack
traces never follow the same path mine does. I do have the following
call stack from the Java plug-in console, though. Any ideas would be
greatly appreciated.

There is a known bug on earlier 1.3.1 releases with sockets on Windows 2k
and XP. I don't remember all the details.

I'm getting the exception on the client, which is an XP machine, while
the server is Win2K. I can't recall which, but either the applet or
the server runs 1.3x while the other runs 1.4. I discounted that
factor, though, as the problem only occurs on one site, which on all
others it works fine.

Exception is in the applet or on the server?
Would one of those by any chance be running on W2K with JDK 131_01 orolder?

I am getting a SocketException when a Java applet talks to our
WebLogic 7.0 server. The catch is that it only occurs at one site
(that has very high T1 utilization, although latency is only ~60 ms)
Our setup is such that the calls hit an Alteon load balancer, which
then sends the request out to one of 4 IIS clustered servers, where it
then is sent to one of 2 WL clustered servers. I figured latency
would be the cause, but on IIS and on WL, the timeouts are set to
several hundred seconds, so I am not quite seeing where the connection
is being reset. To be honest, I really don't know if it is WL that is
killing the connection, as nothing abnormal shows up in the WL log. I
have seen similar problems in this group, though, although the stack
traces never follow the same path mine does. I do have the following
call stack from the Java plug-in console, though. Any ideas would be
greatly appreciated.

Sending Control-Z to Input Stream

Hi everyone,
I'm writing an interface to a command line program, and
one of it's features is that it will accept "forms" through
standard input. The default is that notepad will open
when the command is typed, and you can edit the form
through there.
To accept the form through standard input, you have to
send it the form, and then tell it the form is complete.
This is done using the CTRL-Z keypress, at least when
typing the form in with the keyboard.
I need to do this with Java.
There is another post which poses the same question at
http://forum.java.sun.com/thread.jsp?forum=1&thread=3050
so I attempted that solution.. and that didn't work.
I had the system print out the form as it was being written,
and the form displayed properly, followed by what was
supposed to be a CTRL-Z character, which appeared
on screen (DOS Window) as an arrow pointing right.
Here is the code constructing the form and adding what i've been told is "ctrl-z":
new StringBuffer(form+System.getProperty("line.separator")).append(CTRL_Z).append(System.getProperty("line.separator")))CTRL_Z is defined as:
public static final char CTRL_Z = 26;Does anyone have any other suggestions that might be able to help me?
If you need more information/code provided, I can do so.
Thanks for any help!
Kefka.

You can't actually send anything to an input stream. But let's suppose you have an output stream somewhere that is connected to the standard input of this command line program. Try sending a byte, not a character, that contains 26 to it (yes, ctrl-z is indeed 26). This has a better chance of working than the character idea, because Java is going to translate your character-26 from Unicode to bytes using your system's default encoding. And I can't predict what that might end up as. But it will leave the byte 26 alone and just send it... I hope. Can't guarantee this.
