  • Hey Guy , I want ot streaming video by using VideView class . Can anyone tell me what format is it s

    - by eddyxd
    Hi , I am the newbie of android, but i hava seen the tutorial and implement some simple applications. The question i met is that I am tring to stream some video from my server to android, but the android VideoView class just plays the audition sololy without "image"@@!~ Here is my setting and android code : 1. android core code: mVideoView01.setVideoURI(Uri.parse("rtsp://192.168.16.1:8080/test.sdp")); mVideoView01.start(); 2. my streaming server is VLC and the command is: vlc -vvv d:\nobody.mp4 --sout=#transcode{vcodec=h264,width=320,hegiht=240}:rtp{dst=192.168.16.1,port=4444,sdp=rtsp://192.168.16.1:8080/test.sdp} ps: My ip is got from DHCP but I have checked it really can be connected(Android could play audition after all) ps2: I haved trid to stream some video from "http://www.americafree.tv/" and the playing is good!!@@ So I guess that the problem maybe is caused by streaming Video format, but I have almost tried every figument option form VLC, and it still don't workQQ. So Have anyone done the same test as me can give me some advice?? Thanks a lot!!!!! by eddy

  • How to get Firebug to tell me what error jquery's .load() is returning?

    - by Edward Tanguay
    I'm trying to find out what data/error jquery's .load() method is returning in the following code (the #content element is blank so I assume there is some kind of error). Where do I find in Firebug what content or error .load() is returning? How can I use console.log to find out at least what content is being returned? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $('#loadButton').click(loadDataFromExernalWebsite); }); function loadDataFromExernalWebsite() { console.log("test"); $('#content').load('http://www.tanguay.info/web/getdata/index.php?url=http://www.tanguay.info/knowsite/data.txt', function() { alert('Load was performed.'); }); } </script> </head> <body> <p>Click the button to load content:</p> <p id="content"></p> <input id="loadButton" type="button" value="load content"/> </body> </html>

  • In UISplitViewController rootView/masterView to tell detailView to push a viewcontroller ?

    - by arash13
    This is almost a follow up of my last question. Now i have a splitview with a rootview / leftview that has a table and detailview / rightView that has some view controller pushed into it's navigationcontroller. So this is what i want to achieve: When i tap on a tablerow on my rootView , i want my detail view to push a viewController associated with that row... any ideas ? I also tried making a protocol on my tableviewcontroller and have it implemented in detailview controller .. but i dont know how to call it, is it [self performselector:.... ? case 1:{switch ([indexPath row]) { case 0:{[_detailViewController.navigationController pushViewController:_s2d animated:YES]; // just trying to push it from here but didnt work }break; case 1:{ [_detailViewController loadEqViewController]; // this one is an instance method in detailview it is being called but nothing happends }break; }}break;

  • How to tell if XUL menupopup opens down or up?

    - by Jon
    I have an extension that can be placed on any toolbar (like the bookmarks, menu or status bars). In general, the context menu opens downward, but when placed on the status bar and Firefox is closed to the bottom of the screen, the context menu opens upward. I'd like to try reordering the context menu based on its up or down orientation, so that the same options are always closest to the mouse. For example, when opened downward it appears like this: -- (mouse) --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- When it opens upwards its like this: --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- -- (mouse) However, I'd like "MenuItem A" to appear closest to the mouse at all times, since its the most common item. I can render the items dynamically, so I really just need to find out the orientation.

  • Applescript to connect to bluetooth device

    - by Mark117
    I'm trying to create an applescript to allow me to connect to a bluetooth device by it's Bluetooth ID. So far, i've managed to get an applescript to turn on bluetooth if it's off. Here's the code: # This is only necessary, if AppleScripts are not yet allowed to change checkboxes tell application "System Events" to set UI elements enabled to true # Now change the bluetooth status tell application "System Preferences" set current pane to pane id "com.apple.preferences.bluetooth" tell application "System Events" tell process "System Preferences" # Enabled is checkbox number 2 if value of checkbox 2 of window "Bluetooth" is 0 then click checkbox 2 of window "Bluetooth" end if end tell end tell quit end tell Would someone know if and how it's possible to set up a new bluetooth device and if it'd be posible to connect to a device based on it's device name/ it's device bluetooth ID? I've also tried to record the action in Automator but for the "set up new device" option, Automator just tells me: "click on "" button". Thanks

  • C# How to to tell what process is using a file?

    - by JL
    I am getting a pretty common, "The process cannot access the file because it is being used by another process." Now I am nearly certain that the only process accessing this file is from code that I have written and I've been careful to use a using statement around accessing it. But to be 100% sure, is there anyway to check this programatically when this error occurs?

  • On WindowsMobile, how can i tell what other processes are reserving shared memory space?

    - by glutz78
    On WindowMobile 6.1, I am using VirtualAlloc to reserve 2MB chunks, which will return me an address from the large shared memory area so allocations do not count against my per process virtual space. (doc here: http://msdn.microsoft.com/en-us/library/aa908768.aspx) However, on some devices i notice that I am not able to reserve memory after a certain point. VirtualAlloc will return NULL (getlasterror() says out of memory). The only explanation for this that I see is that another process has already reserved a bunch of memory and my process is therefore unable to. Any idea where I can find a tool to show me the shared mem region of a WM device? Thanks.

  • How do I dynamically tell a .NET MVC application which datasource to point to?

    - by Bialecki
    I'm beginning a port of an existing ColdFusion application to .NET MVC and one of the first issues I'm running into is that in ColdFusion we use the fact that you can define multiple datasources and access them in a dynamic way so that a particular user can be pointed at a particular database. To give an example, I might have two databases, Foo and Bar which each have a table called Locations which store locations particular to that database. The databases are guaranteed to have the same tables, so that's not a concern. In ColdFusion, you can easily dynamically point a user towards a particular datasource because it's just a string which is configured via the ColdFusion administrator (or you could programatically modify an XML file). So the question is how to do this in .NET? And specifically, I think I'd really like to use the Entity framework to leverage the ORM support it'll offer to perform operations on the data in the database, but I'm not sure how to do that (hopefully it's possible). Any thoughts?

  • R: How to tell lapply to ignore an error and process the next thing in the list?

    - by John
    I have an example function below that reads in a date as a string and returns it as a date object. If it reads a string that it cannot convert to a date, it returns an error. testFunction <- function (date_in) { return(as.Date(date_in)) } testFunction("2010-04-06") # this works fine testFunction("foo") # this returns an error Now, I want to use lapply and apply this function over a list of dates: dates1 = c("2010-04-06", "2010-04-07", "2010-04-08") lapply(dates1, testFunction) # this works fine But if I want to apply the function over a list when one string in the middle of two good dates returns an error, what is the best way to deal with this? dates2 = c("2010-04-06", "foo", "2010-04-08") lapply(dates2, testFunction) I presume that I want a try catch in there, but is there a way to catch the error for the "foo" string whilst asking lapply to continue and read the third date?

  • Javascript: how to tell if a node object has been inserted into a document/another element yet

    - by thomasrutter
    I'd like to be able to identify whether a given DOM node has been appended/inserted into another node yet, or whether it is fresh out of document.createElement() or similar and has not been placed anywhere. In most browsers just checking the parentNode works. if (!node.parentNode) { // this node is not part of a larger document } However, in Internet Explorer it appears that new elements, even right after they've been created with document.createElement() already have a parentNode object (of type DispHTMLDocument??). Any other nice cross-browser and reliable way? Edit: looks like Internet Explorer is implicitly creating a DocumentFragment (with nodeType of 11) and setting that as the node's parentNode property.

  • Opengl Iphone SDK: How to tell if you're touching an object on screen?

    - by TheGambler
    First is my touchesBegan function and then the struct that stores the values for my object. I have an array of these objects and I'm trying to figure out when I touch the screen if I'm touching an object on the screen. I don't know if I need to do this by iterating through all my objects and figure out if I'm touching an object that way or maybe there is an easier more efficient way. How is this usually handled? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesEnded:touches withEvent:event]; UITouch* touch = ([touches count] == 1 ? [touches anyObject] : nil); CGRect bounds = [self bounds]; CGPoint location = [touch locationInView:self]; location.y = bounds.size.height - location.y; float xTouched = location.x/20 - 8 + ((int)location.x % 20)/20; float yTouched = location.y/20 - 12 + ((int)location.y % 20)/20; } typedef struct object_tag // Create A Structure Called Object { int tex; // Integer Used To Select Our Texture float x; // X Position float y; // Y Position float z; // Z Position float yi; // Y Increase Speed (Fall Speed) float spinz; // Z Axis Spin float spinzi; // Z Axis Spin Speed float flap; // Flapping Triangles :) float fi; // Flap Direction (Increase Value) } object;

  • Can Java Code tell if it is in an App Server?

    - by Grasper
    Is there something I can call from a POJO to see if the code is currently in an App Server or outside of an App Server? Something like this (In rough PseudoCode): System.getRunningEnvironment().equals(Environment.Glassfish) or System.getRunningEnvironment().equals(Environment.ApplicationServer) or System.getRunningEnvironment().equals(Environment.JavaSE)

  • How to tell if two exe's are the same code-wise?

    - by yumcious
    Is there a way to detect whether two EXE's (compiled from VS.Net 2008 for C++/MFC) do not have any code-level changes between them i.e. for purposes of knowing that there have been no statement changes. This is for compliance purposes when my vendor ships me an exe, ostensibly with no changes made to the code since the last time we tested it. Is there a tool to check that this is so? Cheers

  • Is there a way to tell .NET where to look for the user settings file?

    - by Davy8
    Basically multiple instances of our application will be launched but they need to have separate user settings. We currently have use "user settings" for that, and it works fine for a single instance (per windows user) but we would like to be able to launch multiple instances with say a settings path passed in via command line. Is there a way to do this with the built-in .NET settings or will we have to roll our own?

  • How to tell Eclipse 3.4 WTP to not restart tomcat on JSP save?

    - by Boden
    Whenever I save a JSP file in my WTP project, Eclipse restarts its Tomcat instance. This is sorta driving me nuts. I don't want to disable auto reload completely, I just don't want it to happen when I save a file that doesn't require a restart. I'm not sure how Eclipse WTP works in this regard. Could it be my project structure? The JSP files are in WEB-INF/jsp. (this SO question is similar to mine, but doesn't have a sufficient answer) EDIT: I want auto-reloading to happen, but not for file saves that do not require it. When I save a JSP there is no reason to have Tomcat restart. Thus what I'm looking for, if possible, is a smarter way for reloading to happen.

  • Why does ANT tell me that JAVA_HOME is wrong when it is not?

    - by Ankur
    I get the error: C:\dev\ws\springapp\build.xml:81: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre6" But I have clearly set my JAVA_HOME to be C:\Program Files\Java\jdk1.6.0_14 Where is ANT getting this value?

  • How to tell axis2 to use an existing object as a service?

    - by Christian Hausknecht
    I am trying to expose some methods of a running application as a webservice. The core idea is to use an embedded web-server and send the soap messages to the apache axis2 framework in order to invoke the services. The problem is, that axis2's createService methods only accept Classes as parameter, not existing objects. So I believe that axis2 itself creates an object of the service class and then uses it to call methods when an external service call arrives. But I need to pass an existing object for being used as a service, because I need to call methods of other objects of the running application within the service methods. So the "standard" way that axis2 creates a new instance of the service class and calls then its methods is obviously no sulution for me. So is there a way to realize this? Or is there another solution? Perhaps you can pass objects later on to the allready created service object by axis2? If there is another solution without axis2 I might consider that one. Basically I am only interested in exposing some functionality of a runnning application as a webservice.

  • How do I tell gcc to relax its restrictions on typecasting when calling a C function from C++?

    - by Daryl Spitzer
    I'm trying to use Cmockery to mock C functions called from C++ code. Because the SUT is in C++, my tests need to be in C++. When I use the Cmockery expect_string() macro like this: expect_string(mock_function, url, "Foo"); I get: my_tests.cpp: In function ‘void test_some_stuff(void**)’: my_tests.cpp:72: error: invalid conversion from ‘void*’ to ‘const char*’ my_tests.cpp:72: error: initializing argument 5 of ‘void _expect_string(const char*, const char*, const char*, int, const char*, int)’ I see in cmockery.h that expect_string is defined: #define expect_string(function, parameter, string) \ expect_string_count(function, parameter, string, 1) #define expect_string_count(function, parameter, string, count) \ _expect_string(#function, #parameter, __FILE__, __LINE__, (void*)string, \ count) And here's the prototype for _expect_string (from cmockery.h): void _expect_string( const char* const function, const char* const parameter, const char* const file, const int line, const char* string, const int count); I believe the problem is that I'm compiling C code as C++, so the C++ compiler is objecting to (void*)string in the expect_string_count macro being passed as the const char* string parameter to the _expect_string() function. I've already used extern "C" around the cmockery.h include in my_tests.cpp like this: extern "C" { #include <cmockery.h> } ...in order to get around name-mangling problems. (See "How do I compile and link C++ code with compiled C code?") Is there a command-line option or some other means of telling g++ how to relax its restrictions on typecasting from my test's C++ code to the C function in cmockery.c? This is the command I'm currently using to build my_tests.cpp: g++ -m32 -I ../cmockery-0.1.2 -c my_tests.cpp -o $(obj_dir)/my_tests.o
