I am trying to draw a video into a sprite, but after starting to play the video, I see one frame from the video for a split second and then just a black screen
And at the same time on AVD everything work fine
I tried different options and the result is the same, tried draw video to mash and replace MediaPlayer to ExoPlayer, but nothing

Hello, could you integrate with exoplayer?

Would be awesome to see all the new features (incl. ext codec support)

Hi,

I tried both Official and Snapshots repo, but there is no gdx-video and I can not build it with gradle.

Hello. I am interested in using gdx-video for playing streaming video. Video is received from the internet and should be played in libgdx game. Is there a way to expand this code to support this feature? I have working code that plays .mp4 video and would like to modify it to play streaming video. It would be enough if you can provide few tips on how to do this.

Hi, so I'm trying to replay a video once it completes, but trying to do this throws an IllegalStateException.

Here's the error:

Here is the initial method creating the video:

 private void createVideo()
    {
        try
        {
            videoPlayer = VideoPlayerCreator.createVideoPlayer(videoViewPort);
            videoPlayer.play(Gdx.files.internal("restvideo.mp4"));
        }
        catch(Exception e)
        {
            Gdx.app.log("EXCEPTION", e.toString());
            videoPlayer = null;
        }
    }

Here is the check for looping the video if it is done in the batch.

if(videoPlayer != null)
        {
            videoViewPort.apply();

            if(videoPlayer.isBuffered()) {
                if (!videoPlayer.render()) {
                    try {
                        videoPlayer.play(Gdx.files.internal("restvideo.mp4"));
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }
                }
            }
        }

Not sure if this is a bug or me doing it wrong, anyone?

It will be great not to grab the screenshots manually and then convert them using third-party tools to video. If possible it will be very useful to create such videos using this extension with pretty interface, and awesome if it will be possible to collect audio at the same time, at least on desktop :)

So the question is - is it possible? I mean not now, but is it possible for implementation in general? May be you already have some plans about it?

And of course thanks for a great work 👍

I have a following snippet in Scala which works on desktop, but fails on Android 4.1 (Genymotion emulator):

val videoFile = Gdx.files.internal("vid/a.ogg")
println("video file exists: " + videoFile.exists())
video = VideoPlayerCreator.createVideoPlayer()
video.play(videoFile)

Log from failure (it doesn't crash the app, just skips playing the video):

Notice the video file exists: true followed by java.io.FileNotFoundException: a.ogg, I'm very confused 😕.

Could this be related?

Any help would be appreciated.

Hello, I have been getting nothing every time I try to generate the .jar files.
I think the error is mine.... Would you share with me the .jar file for Linux, Android, Windows and Mac as possible as you can?

Thanks....

Any clues why?

Hi,

i stumbled upon a nasty bug that happens quite often when calling VideoPlayer.dispose() (or VideoPlayer.stop()), on desktop (Mac). I traced the error down to the VideoDecoder destructor where it seems like something is deallocated a second time or was never allocated (pointer being freed was not allocated, see crash report below). I couldn't debug any further because I wasn't able to (re)compile the native libs. I am using the prebuilt ones you offered in another issue.

Here's the crash report:

Any idea?

I'm trying to implement this into my existing project via a tool to test it and I'm having issues where gdx-jnigen must be manually added as a dependency due to the use of JniGenSharedLibraryLoader at com.badlogic.gdx.video.FfMpeg.loadLibraries(FfMpeg.java:49). I've noticed that it was explicitly excluded as a transitive dependency, however it's included in with extensions such as gdx-box2d which also use native libraries.

https://github.com/libgdx/gdx-video/blob/master/gdx-video-desktop/src/com/badlogic/gdx/video/FfMpeg.java#L47-L52

In the meantime, I've just added it to my dependencies

MediaPlayer initialization is performed on the main looper thread, but not all accesses to 'player' are correctly synchronized:

• stop()
• dispose()
• isPlaying()
• setVolume()

In addition, the done/prepared flag should be made volatile since they're also written to from the looper thread.

Why is the initialization of the MediaPlayer done on the main looper anyway? Can't you use the current thread's looper (or create it if one doesn't exist yet)?

When using gdx-video on android I found that the VideoPlayerAndroid implementation doesn't adhere to the viewport (fill,fit etc) that it is instantiated with. It's a small viewport/camera problem.

[VideoPlayer::loadFile] Error opening file: Invalid data found when processing input

@robbiedobbie Which file formats are supported?

I'm attempting to use gdx-video, with some modification, to show simultaneous videos at their true size. I've created a VideoPlayer for each video by providing an OrthographicCamera and Mesh. This construction does not work with the current VideoPlayerAndroid.java's player.setOnPreparedListener for a few reasons, but I've replaced the code with the following:

      player.setOnPreparedListener(new OnPreparedListener() {
            @Override public void onPrepared (MediaPlayer mp) {

                float w = mp.getVideoWidth();
                float h = mp.getVideoHeight();

                cam.viewportWidth = w;
                cam.viewportHeight = h;
                cam.position.set(w/2f, h/2f, 0);
                cam.update();

                mesh.setVertices(
                        new float[] {
                                0, 0, 0, 0, 1,
                                w, 0, 0, 1, 1,
                                w, h, 0, 1, 0,
                                0, h, 0, 0, 0
                        });

                 prepared = true;
                 if (sizeListener != null) {
                      sizeListener.onVideoSize(w, h);
                 }
                 mp.start();
            }
      });

I've loaded two videos -- 320x240 and 640x360 -- and they are rendered at the particular positions by calling Gdx.gl.glViewport(locX, locY, videoWidth, videoHeight) prior to rendering and then afterwards calling glViewport to set it back to the device extents.

A screenshot from a Galaxy Tab 2 7" is shown below. The correct outline of video placement is the 1px red border. I'm having trouble setting the camera and mesh so that the video is displayed in the correct proportion. Can you provide some guidance?

I want to manage the texture using model instance as it manages the transforms and all. I figured I can achieve this if i can play it on the GLTexture instance instead of the Android Texture. But I can't figure out a way to replace android Texture with GLTexture of libGDX. Android's Media Player requires a Surface in which we can pass a SurfaceTexture but not GLTexture.

 private int[] textures = new int[1];
 GLES20.glBindTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, textures[0]);
 player.setSurface(new Surface(new SurfaceTexture(textures[0])));

Any help would be appreciated

Hello,

Revisiting this extension after some inactivity and am currently trying to get mp4 video working on android. I have created a Screen that should be playing video. The problem is that the screen remains blank but the audio plays in the background.

Can you provide any guidance? Ideally I want to be able to render video on android onto a specific texture (in an Actor) so that I can put it in a stage and have other Actors rendered on top of the video.

Below is an excerpt of my Screen class:
`public VideoPlayer videoPlayer;

boolean videoLoaded = false;

@Override
public void show() {

    videoPlayer = VideoPlayerCreator.createVideoPlayer();
    videoPlayer.resize(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
    videoPlayer.setOnVideoSizeListener(new VideoPlayer.VideoSizeListener() {
        @Override
        public void onVideoSize(float v, float v2) {
            videoLoaded = true;
        }
    });

    try {
        videoPlayer.play(Gdx.files.absolute("/path/to/file.mp4"));

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

    Gdx.gl.glEnable(GL20.GL_CULL_FACE);
    Gdx.gl.glCullFace(GL20.GL_BACK);

}

@Override
public void render(float delta) {

    Gdx.gl.glClearColor(0, 0, 0, 1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

Curious if there's any benefit to FFMpegInterop ( https://github.com/Microsoft/FFmpegInterop ) GDXVideo bindings?

On desktop, is the windows media pipeline inherently superior?

I was wondering if there is any chance of iOS support (or maybe someone can point me towards a iOS/robovm solution).

The currentVideoWidth/currentVideoHeight fields in VideoPlayerDesktop are never written to, so they're always 0.

This affects the sizeListener and the getVideoWidth/getVideoHeight methods.

Hello,

So after some elbow grease I was able to get this library incorporated into my project and is happy to see that I can play OGV files on windows and MP4 on android. I am currently trying to make an app that will need to be able to play MP4 files on android, windows, and linux.

I have tried and failed to get MP4 files to play on Windows so either I am doing something wrong or MP4 is currently not supported. If that is the case how do I go about getting this library to play MP4 files on windows/linux?

Regards,

N

Hello everyone.
Is it possible to write video files with this? Not recording, just load/save (eventually, trimming)

Thanks.

I am new to Java/Android development. Using Android Studio 1.5.1. I've built gdx-video and gdx-video-android to two jar files using jdk1.8.0_66\bin\jar.exe cfv filename.jar *. I added the two files to a libs folder just under my libgdx project (at the same level as core and android folders). In my project's build.gradle I added these lines to both the core and android dependencies blocks:

compile fileTree(dir: '../libs', include: '*.jar')

then resync'd gradle and added the following inside the ApplicationAdapter's create():

    videoPlayer = VideoPlayerCreator.createVideoPlayer();
    videoPlayer.resize(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
    videoPlayer.setOnVideoSizeListener(new VideoPlayer.VideoSizeListener() {
        @Override
        public void onVideoSize(float v, float v2) {
            videoLoaded = true;
        }
    });

Android Studio asks to import the unknown class com.badlogic.gdx.video.VideoPlayer, I respond with Alt+Enter and it prompts again for the same import. If I add com.bad.logic.gdx.video.VideoPlayer manually, .video is not recognized.

What step am I missing? Thank you.

I have a loopable video that I am looping by doing this in the render loop (Android):

Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
 if (videoPlayer != null) {
            if (!videoPlayer.render()) {
                try {
                    videoPlayer.play(movieFile);
                } catch (FileNotFoundException e) {
                    videoPlayer = null;
                    Gdx.app.log("EXCEPTION", "Could not loop video", e);
                }
            }
        }

Whenever the video is done playing, it will flicker once to black before it resumes playing. Currently I remove the glClear to make it less visible, but this is not really an approach I'd like to keep in the future.

Anyone have any suggestions or is this a limitation in the android mediaplayer?

I am getting this and similar errors for all gdx-video related libs I included in my project's gradle build scripts. I followed instructions on main page. Is there anything else I need to do?

After trying various formats, gdx-video seems to work perfectly on desktop. On Android, the video plays just fine, but whenever the video begins playback, it is consistently about 5 seconds into the video, thus causing the first few seconds of the video to be omitted. I've tried using some different formats, just in case it was just .webm videos, but encoding in other formats produces the same or worse results.(Black screen with....ogv on Android, I believe. I'll just stick to .webm) Whenever I playback the same video in Android's Media Player, it works just fine. One solution would be to add a delay at the beginning of each video, but that isn't very elegant. I tried poking around the code to see if there is something that I can call to reset the video once it is loaded, but that hasn't gotten me anywhere. lol I My current game focuses on audio-video sync, so this harms the experience on Android. Any clues as to why it starts so far into the video?

It would be nice to have one format of video which could be used on desktop and Android (after all e.g. tablets and desktops are closing fast). From what I read FFmpeg library can be compiled with VP8 and WebM support (unfortunately I have no clue how to do that).

I am looking for YouTube video playing solutions in libGDX, so I have found this repo.
Can you please explain in a few sentences, how can it used?
Thanks in advance!

I'm trying to use this library for my libgdx project and I think it works fine with the compiled library but I get the error "com.badlogic.gdx.backends.lwjgl3.audio.OpenALAudio cannot be cast to com.badlogic.gdx.backends.lwjgl.audio.OpenALAudio" because I'm using lwjgl3 and RawMusic uses lwjgl, could you please send me a compiled library for lwjgl3? because I tried to built it and i get java.lang.NoClassDefFoundError when I try to use it

Hello, i tried the maven build but i can't download the gdx-video-desktop-natives.jar
I can't find it in any of my repos including the one mentioned in read.me

Could you help?

When you try to create a video player using a custom mesh you get a NullPointerException: Attempt to invoke virtual method 'void com.badlogic.gdx.graphics.glutils.ShaderProgram.begin()' on a null object reference. When I opened up VideoPlayerAndroid.java I noticed shader is never instantiated in the third constructor:

`
public VideoPlayerAndroid () {
this(new FitViewport(Gdx.graphics.getWidth(), Gdx.graphics.getHeight()));
}

 public VideoPlayerAndroid (Viewport viewport) {
	  shader = new ShaderProgram(vertexShaderCode, fragmentShaderCode);
	  setupRenderTexture();

	  this.viewport = viewport;
	  cam = viewport.getCamera();
	  mesh = new Mesh(true, 4, 6, VertexAttribute.Position(), VertexAttribute.TexCoords(0));
	  //@formatter:off
	  mesh.setVertices(new float[] {0, 0, 0, 0, 1, 0, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0});
	  //@formatter:on
	  mesh.setIndices(new short[] {0, 1, 2, 2, 3, 0});
 }

 public VideoPlayerAndroid (Camera cam, Mesh mesh, int primitiveType) {
	  this.cam = cam;
	  this.mesh = mesh;
	  this.primitiveType = primitiveType;
	  customMesh = true;
	  setupRenderTexture();
 }

Hey,

I add the android jar file using compile files("libs/gdx-video-android.jar") in Gradle given it is not on Sonatype yet. I am able to use the class in Android Studio, however when I run it on the device I get the following exception at runtime.

Stacktrace: http://pastebin.com/QKZPqjEd

Any idea?

I apologize for my lack of experience, but can you create a video or a written tutorial about how to get this working? I tried to get this working, but I was just taking shots in the dark and ended up asking others in #libgdx on freenode and, after a few pointers, I was able to get rid of the "NoClassDefFoundError", but now i get this error. I don't know if the error is in the code that I am using(I am using your sample code) or in the .jar files that I added to the build path. It doesn't help that no one has ever tried using this.

The error: http://pastebin.com/T9RnjV5r
The code that I'm using: http://pastebin.com/MjxttDTN

Hello,

I wanted to render video texture on 3d plane. I tried doing for 3D for the modelbatch using the 2D example provided in the library, however, I got the GL thread error.

I would be grateful if someone can help me with this.

Thanks :)

Can anyone give me a hint how to set up this library?
I try many times and still not work.
I set the "Gradle dependency declarations" as readme said in build.gradle but still not working.

Hello,
i use the VideoPlayer in a Screen.
I do vPlayer = VideoPlayerCreator.createVideoPlayer();
vPlayer.play(...)

in the initialize method (method which is called before the screen switch)

If i do this - no events are called..
I figured out that this is due to the fact that there is no Looper on LibGdx render thread.

So i added a handler to initialize and start the player.
But the rendering then crashes on vPlayer.render() because there is a different GL context on textures for the mediaplayer.

I also try to call Looper.prepare() on the render thread but i get error that only one looper can exist.

Can you please suggest how can i create a working video player on a render thread of LibGDX game/screen?

Thanx

Im executing at the shell "./gradlew jnigenBuild" on debian

I couldn't find anywhere what the minimum device API this library supports? I am only asking since I'm having some issues with playback on lower API emulators, but it seems work on actual devices.

With gradle i get the following build error:

Could not find com.badlogicgames.gdxvideo:gdx-video:0.0.1.
Searched in the following locations:
    https://repo1.maven.org/maven2/com/badlogicgames/gdxvideo/gdx-video/0.0.1/gdx-video-0.0.1.pom
    https://repo1.maven.org/maven2/com/badlogicgames/gdxvideo/gdx-video/0.0.1/gdx-video-0.0.1.jar

Why this JARs arent available in Maven Central anymore?

Hello,

Setup: I was able to recompile the native libraries for desktop with support for mp4. The device I was testing on was a mini PC (Windows 10, Intel Atom Cherry Trail X5 z8300, 2GB RAM). The Libgdx project is just a desktop project that just plays a video upon starting up.

Issue: As far as I can tell, video playback is fine with some videos and just freezes with others.

Additional information: I went and enabled debugging in the videodecoder.cpp and noticed that the issue seems to occur when the number of buffer frames drops to zero (assuming that the buffer index caught up to the buffered frames). In nextVideoFrame(), I noticed that its locking but not unlocking when the number of buffered frames is less than 1 (not sure if this is intentional since the following issue occurs after unlocking). After adding in an unlock before returning, I don't hit the freezing issue anymore but then the video starts skipping back and forth in between frames. (Seemingly jumping back a couple of frames?)

I'm still trying to figure out how everything works so I'm might be doing something completely wrong. Please let me know if you have any idea on what's happening or any suggestions/advice to address this issue.

Thanks!

Your gradle coordinates, shown on ReadMe, are wrong, gradle cannot find them anymore.

Sorry to bother you again. While the desktop project worked just fine, the Android project is giving me issues. As stated in the previous issue, I compiled the .jars in Mac OS X 10.10.2. I then switched over to Windows, and was able to get the desktop project working with jars created in Mac. However, whenever I tried adding "gdx-video-android.jar" to my Android project, it resulted in the error "Conversion to Dalvik format failed with error 1". I assumed that the problem could be due to the fact that they were compiled on a different operating system, so I recompiled "gdx-video-android" in Windows.(Although, there were some errors upon importing, Syntax errors, fixed by changing java compliance to 1.5, and issues like "The method isBuffered() of type VideoPlayerAndroid must override a superclass method") Eclipse recommends getting rid of the @OverRide annotations. Not sure why these errors were only present when I import it into Eclipse in Windows. I ignored these errors(didn't wan't to alter the classes) and compiled anyway. While adding the newly generated jar file doesn't result in the "conversion to dalvik" issue, it results in this error(http://pastebin.com/KKAnEwjs). Assuming this problem stems from the errors when importing in Windows, could you provide your compiled gdx-video-android.jar(that has worked in the past, of course)? Is this jar the only .jar that I need to add to the build path of the android project?

Hello,

I am currently experiencing framerate issues when playing mp4 videos on desktop. At first I thought it was a decoding speed issue but when i commented out the line
showAlreadyDecodedFrame = true;
At the bottom of the render function in VideoPlayerDesktop and then play the video then the video renders very smoothly (albeit at fast forward pace of 60 ish frames per second).

I understand that the variable showAlreadyDecodedFrame is being used to try to play the videos at the framerate they should be at (25 fps or whatever) my syncing the video play time via frame timestamp and the application play time but it seems I am just getting jerky video. Is there any code tweak recommendations you can make regarding this to make the playback timing sync smoother?

Regards,

N

I wonder if there is any best practices or recommendations for video playback on the newest Intel HD graphics as far as hardware accelerated video decoding.

Is H264 the recommended format?

Hi,

When playing a video in a Windows VM running on a Mac, everything is fine and video and audio are in sync. On the same machine, not in a VM (so on native MacOS), audio is about one second ahead, breaking lipsync. This also happens on other native Windows machines I tried. The only difference is that the machines where it does not work have a lot more computing power than the VM where it works. Could it be that modern machines introduce a sync issue due to their speed?

I added some debug statements and audio.play() is called less than 10ms before the first frame renders, so it seems they start correctly at about the same moment. I suspect video is playing too slow then and audio runs ahead (audio does sound normal, not too fast).

Is this a known issue?

Thanks for any help.

Maybe this is outside the scope of this project, but I was wondering if I can customize the parameters of ffmpeg and get a stream decoded from a specific codec into a format that LibGDX can handle. When passing in the raw file, I'm seeing [VideoPlayer::loadFile] Error opening file: Invalid data found when processing input, however vlc can play the file fine, and once I convert the file using -c:v vp8 -c:a libvorbis to a webm video like the test video, it works alright.

Hello,

Hope your day is going well. I was trying to add the gdx-video library to the Gradle build file, however, I am getting the error message - Failed to resolve: com.badlogicgames.gdxvideo:gdx-video-android:1.9.12.

I would be grateful if someone can help me with this.

Thanks
