MediaCodec.dequeInputBuffer/dequeOutputBuffer中的IllegalStateException

我正在尝试将PNG文件转换为单片视频片段,以便在项目中启动.

我有什么代码来实现它是: -

private boolean MediaConversion()
    {
        MediaCodec codec = MediaCodec.createEncoderByType(MIMETYPE);
        MediaFormat mediaFormat = null;
        if(CamcorderProfile.hasProfile(CamcorderProfile.QUALITY_720P)){
            mediaFormat = MediaFormat.createVideoFormat(MIMETYPE, 1280 , 720);
        } else {
            mediaFormat = MediaFormat.createVideoFormat(MIMETYPE, 720, 480);
        }

        mediaFormat.setInteger(MediaFormat.KEY_BIT_RATE, 700000);
        mediaFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 10);
        mediaFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420SemiPlanar);
        mediaFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5);
        codec.configure(mediaFormat, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

        codec.start();

        ByteBuffer[] inputBuffers = codec.getInputBuffers();
        ByteBuffer[] outputBuffers = codec.getOutputBuffers();
        boolean sawInputEOS = false;
        int inputBufferIndex= -1, outputBufferIndex= -1;
        BufferInfo info=null;        

        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        Bitmap bitmap = null;
        try {
        bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.image);                    
            Log.e("Uploaded", "Bitmap:" + bitmap.getWidth() + "X" + bitmap.getHeight());
        } catch (Exception e) {
            e.printStackTrace();
        }
        bitmap = Bitmap.createScaledBitmap(bitmap, WIDTH, HEIGHT, false);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100,
                byteArrayOutputStream);

        byte[] dat = byteArrayOutputStream.toByteArray();
        info = new BufferInfo();

         **// Exception occurred on this below line in Emulator, LINE No. 182//**
        inputBufferIndex = codec.dequeueInputBuffer(WAITTIME);
            if(dat.length<=0)
                sawInputEOS=true;

            if(inputBufferIndex >= 0){
                if(!sawInputEOS){
                    int samplesiz= dat.length;
                    inputBuffers[inputBufferIndex].put(dat);
                    codec.queueInputBuffer(inputBufferIndex, 0, samplesiz, presentationTime, 0);
                    presentationTime += 100;

               **// Exception occurred on this below line in DEVICE, LINE No. 193 //**
                    outputBufferIndex = codec.dequeueOutputBuffer(info, WAITTIME);
                    Log.i("BATA", "outputBufferIndex="+outputBufferIndex);
                    if(outputBufferIndex >= 0){
                        byte[] array = new byte[info.size];
                        outputBuffers[outputBufferIndex].get(array);

                        if(array != null){
                            dos = array;
                        }

                        codec.releaseOutputBuffer(outputBufferIndex, false);
                        inputBuffers[inputBufferIndex].clear();
                        outputBuffers[outputBufferIndex].clear();

                    }
                }else{
                    codec.queueInputBuffer(inputBufferIndex, 0, 0, presentationTime, MediaCodec.BUFFER_FLAG_END_OF_STREAM);

                    outputBufferIndex = codec.dequeueOutputBuffer(info, WAITTIME);
                    Log.i("CHAK", "outputBufferIndex="+outputBufferIndex);

                    if(outputBufferIndex >= 0){
                        byte[] array = new byte[info.size];
                        outputBuffers[outputBufferIndex].get(array);

                        if(array != null){
                            dos = array;
                        }

                        codec.releaseOutputBuffer(outputBufferIndex, false);
                        inputBuffers[inputBufferIndex].clear();
                        outputBuffers[outputBufferIndex].clear();
                    }
                }
            }       


        codec.stop();
        codec.release();
        codec = null;

        return true;
    }

这是异常日志: -
