  • FFMPEG and JNI - pass AVFrame data to Java and Back

    17 octobre 2015, par tishu

    I have some C code that decodes a video frame by frame. I get to a point where i have an AVFrame in BGR32 and would like to send it back to Java for editing.

    I have a ByteBuffer object in my C code that was created in Java using AllocateDirect but i struggle to write the content of the AVFrame->data[0] (of uint8_t type) to it and read it back. I have tried memcpy with no luck. Does anyone have an idea how to achieve this ?

    UPDATE
    Followed Will’s comment below and wrote this in C

    char *buf = (*pEnv)->GetDirectBufferAddress(pEnv, byteBuffer);
    
memcpy(buf, rgb_frame->data[0], output_width*output_height*4);

    The buffer does contain some data in Java but doing the following returns a null bitmap

    BufferedImage frame = ImageIO.read(bitmapStream);

    Where bitmapStream is a ByteBufferInputStream defined here :
    https://code.google.com/p/kryo/source/browse/trunk/src/com/esotericsoftware/kryo/io/ByteBufferInputStream.java?r=205

    Not sure if I am not writing things correctly in this buffer

    UPDATE 2

    Got pretty close now thanks to the latest snippet. I am using BGR32 format in my C code ie 4 bytes per pixel. So I modified things a bit in Java :

    final byte[] dataArray = new byte[width*height*4];
    
imageData.get(dataArray);
    
final BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_BGR);
    
final DataBuffer buffer = new DataBufferByte(dataArray, dataArray.length);
    
Raster raster = Raster.createRaster(sampleModel, buffer, null);
    
image.setData(raster);

    I get the image correctly but there seems to be an issue with color channels
    Example

    Tried different formats with no luck
