Media Codec dequeueOutputBuffer IllegalStateException
If you are running this on an emulator make sure that you have selected Graphics as Hardware : GLES 2.0 in Emulator settings. There is some issue with the Software version it seems.

I try to decode a mp3 audio data stream with Android Media Codec. With a sample rate of 44100 the decoding works fine, but the latency is too big. So I set the sample rate to 16000, but now the decoder doesn't work anymore. I get an Illegal State Exception at dequeueOutputBuffer.
This is the part of the code where the problem might be:
bufferInfo = new MediaCodec.BufferInfo(); outputBufferIndex = decoder.dequeueOutputBuffer(bufferInfo, -1); while (outputBufferIndex >= 0) { outputBuffer = decoder.getOutputBuffer(outputBufferIndex); outputBuffer.position(bufferInfo.offset); outputBuffer.limit(bufferInfo.offset + bufferInfo.size); outData = new byte[bufferInfo.size]; outputBuffer.get(outData); track.write(outData, 0, outData.length); decoder.releaseOutputBuffer(outputBufferIndex, false); outputBufferIndex = decoder.dequeueOutputBuffer(bufferInfo, -1); }
I also tried to set the timeout of dequeueOutputBuffer to 0 but this doesn't change anything.
This is the error I receive:
E/SoftMP3: mp3 decoder returned error 1 E/ACodec: [OMX.google.mp3.decoder] ERROR(0x80001001) E/ACodec: signalError(omxError 0x80001001, internalError -2147483648) E/MediaCodec: Codec reported err 0x80001001, actionCode 0, while in state 6 E/AndroidRuntime: FATAL EXCEPTION: Thread-79054 Process: com.example.jonas.audio_client, PID: 26394 java.lang.IllegalStateException at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method) at android.media.MediaCodec.dequeueOutputBuffer(MediaCodec.java:1107)
If I print the Audio Format that the Extractor gets, I see that the Sample-Rate is set to 16000.
D/Format:: {bitrate=32000, mime=audio/mpeg, durationUs=6509000, channel-count=1, sample-rate=16000, bit-rate=32000}
Thanks for any help!

Narendra Singh almost 7 yearsI have tried changing
int bitrate = 450000;
toint bitrate = 32*resultHeight*resultWidth*25 / 100;
but it still didn't work at all. I am getting this same error.
