IllegalStateException w MediaCodec.dequeInputBuffer / dequeOutputBuffer
Próbuję przekonwertować plik PNG na klip wideo z jednym plasterkiem, aby po prostu uruchomić projekt.
To, co miałem, aby to zrobić, to: -
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;
}
A oto dziennik wyjątków: -
