Android :: Flv To Mp4 Conversion
Jun 26, 2009
I want to play the flv files in Android. So what I thought is to convert the flv file to mp4 or 3gp(for which there is a decoder in Android). OpenCore can be used to convert. I have looked into opencore code, there is a class in opencore "/android/external/opencore/fileformats/mp4/composer" to create the mp4 file. It has apis like AddTrack AddSampleToTrack. I should give the input as frames, but in Flv I will get the Sorenson Video and Mp3 audio frame(after doing some trivial string operations to remove the headers). Can I use these directly as input to above apis or is there any good way to convert flv to mp4? And also I have looked into "/android/external/opencore/nodes/pvmp4ffcomposernode" but it reads from ports not able to know how to send input to this class.

We can convert from Intent to URI and from URI to Intent. From Intent to URI string Intent intent1 = new Intent ();
String uriString = intent1.toURI ();
From URI string to Intent Uri uri = Uri.parse (uriString);
Intent intent2 = new Intent ();
intent2.setData (uri)
After conversion, intent1 and inten2 should be same. for example:
Intent intent1 = new Intent ();
intent1.addCategory (Intent.CATEGORY_HOME);
intent1.addCategory (Intent.CATEGORY_LAUNCHER);
Log.v ("", "Intent1 = " + intent1);
if (intent1.hasCategory (Intent.CATEGORY_HOME))
Log.v ("Intent1", "#1 hasCategory TRUE");
else Log.v ("Intent1", "#1 hasCategory FALSE");
String str = intent1.toURI ();
Uri uri = Uri.parse (str);
Intent intent2 = new Intent ();
intent2.setData (uri);
Log.v ("", "Intent2 = " + intent2);
if (intent2.hasCategory (Intent.CATEGORY_HOME))
Log.v ("Intent2", "#2 hasCategory TRUE");
else Log.v ("Intent2", "#2 hasCategory FALSE");
result Intent1 = { categories=android.intent.category.HOME,android.intent.category.LAUNCHER} } #1 hasCategory TRUE
Intent2 {data=#Intent;
category=android.intent.category.HOME;
category=android.intent.category.LAUNCHER;
end } #2 hasCategory FALSE
In this sample code, Intent2 is a conversion result from Intent1. If you run this sample code, Intent1 result and Intent2 result are different. Because Intent1 and Intent2 have a same Intent.CATEGORY_HOEM, the result should be Intent1 and Intent2 is TRUE (intent.hasCategory). I think this is bug. And the hint is Intent1 and Intent2 's toString result is different.
Intent1 = {categories=android.intent.category.HOME,android.intent.category.LAUNCHER}
Intent2 = { data=#Intent;category=android.intent.category.HOME
category= android.intent.category.LAUNCHER;end }
I don't know how to convert Intent to URI(String) and convert URI (String) to Intent. I want to save Intent to DB and read Intent from DB.

I am looking at the source code of a Camera Preview application and learning that the preview buffers coming from the sensor is in YUV422 format. However, this preview frame is showed on the display in RGB. Can someone please let me know where the pixel format conversion happens? Is it inside Surface Flinger? If yes, can you please point me to the code?

I am trying to convert my project o SDK 1.5. It won't build with the errror: "Conversion to Dalvik format failed with error 2"
I have seen other threads refer to problem with annotations, but the code that is causing problems for me has absolutely no java annotations in it (no at-signs whatsoever, except inside javadoc comments). Is there any way to get feedback from Eclipse or the android tools about what the problem is? How am I supposed to even begin to debug this problem?
I am more than happy to change the code where there are problems (the problem is actually a large library that I use, but I use the library as raw code, not a foreign jar, so I have access to the code), but I don't know what to change. That error just doesn't give me much to go on.

I faced to the serious problem when building my environment. I use below software for compiling. android SDK (android 2.1) eclipse 3.5.2. At first, this problem occurred on eclipse 3.6. I looked for the reason and countermeasure on the web. As the result, I re-installed eclipse 3.5.2. however, the problem was not fixed yet... after building, the below message has been displayed. "Conversion to Dalvik format failed with error 1" if you know other countermeasure for this.

I have a simple app I coded for android that I want to go on Blackberry too - How easy is it to get the code over to their SDK and run it working as intended? I was only wondering if anyone knew from experience. The only API's on Droid I really use are camera and face detect.

I'm trying to use the SmugFig SmugMug API on Android. It was designed for J2SE I would imagine, so I'm not sure it will even work on Android, but I figured it was worth trying as opposed to trying to create my own API. When I load the project though, I get the following error: Conversion to Dalvik format failed: Unable to execute dex: null. It doesn't say what package it fails on, just "Android Packaging Problem", but it did not do this before I added SmugFig and it's dependency JARS to the build path. Where should I look? Or does this mainly me that it just won't work with those libraries?

I've been trying to use Eclipse and the Export Wizard to create a signed apk. unfortunately, I cannot seem to generate an UNSIGNED apk. Every time I "clean and build" I get the error below, which I read I can get rid of by "reload" or refresh then building again. however, the debugger automatically signs with the debug key after I do this, defeating the purpose. how do I build the apk w/o signing it?

In my Android appliction in eclipse I get the following error:
UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added: Lorg/xmlpull/v1/XmlPullParser;....
Conversion to Dalvik format failed with error 1
This error only appears if I add a specific external Jar to my project.
I search long time to the right solution but all possible solutions don't work.
I even tried to change to android 1.6 instead of 1.5(current version I use)

I have a working(Released) project that needs some updating. The Project was created with SDK 1.1 on Windows and Ecplise 3.4. A couple months ago i moved away from Windows to Mac and installed all tools on the mac including Android SDK 1.1. Everything was working fine at that time.
I never bothered compiling the project against SDK 1.5 as the program was running fine on a 1.5 Device. But now i need to do some changes and installed SDK 1.5, following the installation guideline (http://developer.android.com/sdk/1.5_r1/ upgrading.html#UpdateYourProjects).
So I build my project against SDK 1.1 (as suggested) and failed with the following error messages : - no classfiles specified - Conversion to Dalvik format failed with error 1
I receive the same error if I compile with SDK 1.5 (clean + build).
First i thought there is something wrong with my code but could not find anything. After that I tried the example JetBoy and received the same error. Using "Fix Project Properties" was without effect for booth projects.

Anyone know why I would be getting the errors below. The message below is showing up in the Console view, and I'm getting a "Conversion to Dalvik format failed with error 1".
My app has been working quite well for some time, and I just tried to update the SDK and DDMS to 0.9.9, and now it won't build.
I've done a search for the CharBuffer class and don't find any matches in my files, but I am using several API's (BUMP, C2DM, Admob). I definitely don't use any of the core-library in my code. If the error message is correct, I just can't quite figure out how to tell which API is the problem without almost wiping out my code base, or starting a new project and copying a few files at a time.
Oh... but the two files at the bottom of the file are missing android-6sdk.properties and android-5sdk.properties. Anyone know where I find them?
I have tried uninstalling and reinstalling but so far, no joy :).
CODE:.........................
In something other than a core library. It is likely that you have attempted to include in an application the core library (or a part thereof) from a desktop virtual machine. This will most assuredly not work. At a minimum, it jeopardizes the compatibility of your app with future versions of the platform. It is also often of questionable legality.
If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine distribution, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message.
If you go ahead and use "--core-library" but are in fact building an application, then be forewarned that your application will still fail to build or run, at some point. Please be prepared for angry customers who find, for example, that your application ceases to function once they upgrade their operating system. You will be to blame for this problem.
If you are legitimately using some code that happens to be in a core package, then the easiest safe alternative you have is to repackage that code. That is, move the classes in question into your own package namespace. This means that they will never be in conflict with core system classes. If you find that you cannot do this, then that is an indication that the path you are on will ultimately lead to pain, suffering, grief, and lamentation.

I've had a Desire for two weeks now. I was in love with the phone... until this problem came up.
I use Outlook and Microsoft Exchange -- and had read all about how Android synced easily. And it did at first. Then, 10 days ago, the calendar stopped syncing. I got a "Client/Server conversion error," and no sync. The problem only effected my calendar -- mail and contacts were synced just fine. After reading a few forums, I did a "Remove account," re-installed the account. It worked fine again. No big deal.
Then it happened again today. I did the Remove/re-install thing again, and again it was cured. Until six hours later.
Is anyone else having this problem with their calendar/exchange sync? Any solution guesses?
Without being able to sync my phone to Outlook, the Desire I love so much is somewhere between frustrating and infuriating.

When she tries to send a picture it says "Converting message to MMS" (I told her that was normal lol) "Charges may apply."...THIS part, the "Charges may apply" part, is the part I am stuck on. I've never seen this on mine. We have the same plan I think, unlimited texting and calling and such...she is sending the picture to a Verizon phone...I mean I told her it is probably just a "btw, it COULD charge you" sorta thing and that it more than likely won't.
