Hi!
I'm trying to get decoded PCM data from a mp3 file using the newly released
NDK.
I have tried different combinations of AudioPlayer and AudioRecorder using
audio source and audio sink like this:
// configure audio source
SLDataLocator_AndroidFD loc_fd = {SL_DATALOCATOR_ANDROIDFD, fd, start,
length};
SLDataFormat_MIME format_mime = {SL_DATAFORMAT_MIME, NULL,
SL_CONTAINERTYPE_UNSPECIFIED};
SLDataSource audioSrc = {&loc_fd, &format_mime};
// configure audio sink
SLDataLocator_AndroidSimpleBufferQueue loc_bq =
{SL_DATALOCATOR_ANDROIDSIMPLEBUFFERQUEUE, 2};
SLDataFormat_PCM format_pcm = {SL_DATAFORMAT_PCM, 1, SL_SAMPLINGRATE_16,
SL_PCMSAMPLEFORMAT_FIXED_16, SL_PCMSAMPLEFORMAT_FIXED_16,
SL_SPEAKER_FRONT_CENTER, SL_BYTEORDER_LITTLEENDIAN};
SLDataSink audioSnk = {&loc_bq, &format_pcm};
However I keep getting errors in the log saying that this combination is not
supported.
Does anyone have any ideas how to get PCM data from a MP3 file using OpenSL?
Maybe it is not possible?
Cheers
