  • ffmpeg frame to android bitmap

    19 février 2015, par grunk

    I’am using ffmpeg (as a library) to decode a h264 packet.
    The decoding part seems ok (at least i think) but i don’t understand how to convert the decoded frame to a format that android can understand and display in an imageView

    jbyteArray Java_com_exemple_ffmpeg_decodeImage(JNIEnv* env,jobject obj, jbyteArray h264Datas)
    
{
    
    jbyte* bufferPtr = (*env)->GetByteArrayElements(env, h264Datas, NULL);
    
    jsize lengthOfDatas = (*env)->GetArrayLength(env, h264Datas);
    
    (*env)->ReleaseByteArrayElements(env, h264Datas, bufferPtr, JNI_ABORT);
    

    
    AVPacket packet = {0};
    
    packet.data = bufferPtr;
    
    packet.size  = lengthOfDatas;
    

    
    int frameFinished = 0;
    

    
    if(packet.stream_index == 0)
    
    {
    
        int res = avcodec_decode_video2(codecCtx, srcFrame, &amp;frameFinished, &amp;packet);
    
        if(res &lt; 0)
    
        {
    
            LOGI("Failed to decode frame\n");
    
        }
    
    }
    

    
    if (!isOutputInit)
    
    {
    
        if(codecCtx->width > 0 &amp;&amp; codecCtx->height > 0)
    
        {
    
            outputBufLen = avpicture_get_size(PIX_FMT_RGBA, codecCtx->width, codecCtx->height);
    
            if(outputBuf != NULL) {
    
                av_free(outputBuf);
    
            }
    
            outputBuf = av_malloc(outputBufLen);
    
            avpicture_fill((AVPicture*)dstFrame, outputBuf, PIX_FMT_RGBA, codecCtx->width, codecCtx->height);
    
            convertCtx = sws_getContext(codecCtx->width, codecCtx->height, codecCtx->pix_fmt,  codecCtx->width,
    
                                        codecCtx->height, PIX_FMT_RGBA, SWS_FAST_BILINEAR, NULL, NULL, NULL);
    

    
            isOutputInit = 1;
    

    
        }
    

    
    }
    

    
    if(frameFinished)
    
        isFrameReady = 1;
    

    
    //Creating data for android
    

    

    
}

    What i want from there is to get a jbyteArray that i can feed to BitmapFactory , or even better an Android Bitmap if that is possible.

    How can i convert the decoded frame to something usable by Android ?
