  • Java - Stream OpenGL Display to Android

    24 octobre 2016, par Intektor

    I tried to solve this problem for days now, but I couldn’t find a working solution. I am trying to stream my game screen (lwjgl) to my android smartphone(I have a frame buffer with the texture), and I already built a fully working packet system and all that stuff. But there are several problem I have no idea how to solve them, first of all, I don’t know in which format I should send the frame buffer, e.g I can’t send it as a Buffered Image, because it doesn’t exist on android. I tried using the jcodec library, but there is no documentation for it, and I didn’t find any examples that fit my case. I think I have to encode and decode it with h264 to make it a realtime live stream(that’s very important). I also heard about ffmpeg (and I found a java library for it : https://github.com/bramp/ffmpeg-cli-wrapper) but there is again no documentation for how to use it to stream it to my mobile. Also I have the problem, that when would get the frames to my smartphone, how can I make them load by the graphics card

    Here is what I have done so far :
    My packet :

    public class ImagePacketToClient implements Packet {
    

    
public byte[] jpgInfo;
    
public int width;
    
public int height;
    

    
BufferedImage image;
    

    
public ImagePacketToClient() {
    
}
    

    
public ImagePacketToClient(BufferedImage image, int width, int height) {
    
    this.image = image;
    
    this.width = width;
    
    this.height = height;
    
}
    

    
@Override
    
public void write(DataOutputStream out) throws IOException {
    
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    
    ImageIO.write(image, "jpg", baos);
    
    baos.flush();
    
    byte[] bytes = baos.toByteArray();
    
    baos.close();
    
    out.writeInt(bytes.length);
    
    for (byte aByte : bytes) {
    
        out.writeInt(aByte);
    
    }
    
}
    

    
@Override
    
public void read(DataInputStream in) throws IOException {
    
    int length = in.readInt();
    
    jpgInfo = new byte[length];
    
    for (int i = 0; i < length; i++) {
    
        jpgInfo[i] = in.readByte();
    
    }
    
}

    The code that gets called after the rendering has finished : mc.framebuffer is the frame buffer I can use :

    ScaledResolution resolution = new ScaledResolution(mc);
    
            BufferedImage screenshot = ScreenShotHelper.createScreenshot(resolution.getScaledWidth(), resolution.getScaledHeight(), mc.getFramebuffer());
    
            ImagePacketToClient packet = new ImagePacketToClient(screenshot, screenshot.getWidth(), screenshot.getHeight());
    
            PacketHelper.sendPacket(packet, CardboardMod.communicator.connectedSocket);
    
            screenshot.flush();
    

    
public static BufferedImage createScreenshot(int width, int height, Framebuffer framebufferIn)
    
{
    
    if (OpenGlHelper.isFramebufferEnabled())
    
    {
    
        width = framebufferIn.framebufferTextureWidth;
    
        height = framebufferIn.framebufferTextureHeight;
    
    }
    

    
    int i = width * height;
    

    
    if (pixelBuffer == null || pixelBuffer.capacity() < i)
    
    {
    
        pixelBuffer = BufferUtils.createIntBuffer(i);
    
        pixelValues = new int[i];
    
    }
    

    
    GlStateManager.glPixelStorei(3333, 1);
    
    GlStateManager.glPixelStorei(3317, 1);
    
    pixelBuffer.clear();
    

    
    if (OpenGlHelper.isFramebufferEnabled())
    
    {
    
        GlStateManager.bindTexture(framebufferIn.framebufferTexture);
    
        GlStateManager.glGetTexImage(3553, 0, 32993, 33639, pixelBuffer);
    
    }
    
    else
    
    {
    
        GlStateManager.glReadPixels(0, 0, width, height, 32993, 33639, pixelBuffer);
    
    }
    

    
    pixelBuffer.get(pixelValues);
    
    TextureUtil.processPixelValues(pixelValues, width, height);
    
    BufferedImage bufferedimage;
    

    
    if (OpenGlHelper.isFramebufferEnabled())
    
    {
    
        bufferedimage = new BufferedImage(framebufferIn.framebufferWidth, framebufferIn.framebufferHeight, 1);
    
        int j = framebufferIn.framebufferTextureHeight - framebufferIn.framebufferHeight;
    

    
        for (int k = j; k < framebufferIn.framebufferTextureHeight; ++k)
    
        {
    
            for (int l = 0; l < framebufferIn.framebufferWidth; ++l)
    
            {
    
                bufferedimage.setRGB(l, k - j, pixelValues[k * framebufferIn.framebufferTextureWidth + l]);
    
            }
    
        }
    
    }
    
    else
    
    {
    
        bufferedimage = new BufferedImage(width, height, 1);
    
        bufferedimage.setRGB(0, 0, width, height, pixelValues, 0, width);
    
    }
    

    
    return bufferedimage;
    
}

    Honestly I don’t want to use this Buffered Image Stuff, because it halfs my framerate, and that’s not good.
    And I don’t have any code for my android application yet, because I couldn’t figure out how I could get this image recreated on Android, and how to load it after that.
    I hope you understand my problem and I am happy about every tip you can give to me :)

  • improve video size ffmpeg webcam stream

    18 juin 2020, par Wolfgang Enfield

    I am trying to use a webcam Logitech Quickcam 9000 to do IRL stream from a Raspberry 3 using Raspberry Pi OS current version, I have FFmpeg installed and no matter what I try the video resolution is never bigger than 320x240 the webcam can output 1600x1200 the output of v4l2-ctl —list-formats-ext

  • Use nvidia hardware acceleration to merge webms with pngs in ffmpeg

    2 février, par Joshi234

    So I need to merge around 18000 webms with with pngs, however on software encoding it's really slow, so I'm trying to use hardware acceleration to make this faster.

    


    I tried a lot of different stuff but none of them seems to work and it gives me generic errors to what I couldn't find anything relavant.

    


    This is the most "succesful" try I had :
ffmpeg -hwaccel cuvid -c:v vp9_cuvid  -i lightray.webm -i card.png -filter_complex "[1]format=argb,colorchannelmixer=aa=0.35[ol];[0][ol]overlay" -colorspace 5 -c:a copy output.webm

    


    Which gives me this error :

    I'm by no means an expert in ffmpeg or in video encoding in general, so I have no idea what this is supposed to mean.
