AacDecoder requires at least 3 frames to decode #386

Prazlin commented 4 years ago

I'm decoding AAC encoded audio data from an rtsp stream using AacDecoder. I copy the data into a Memory Stream, ms, and pass ms to the AacDecoder constructor. It works when ms contains at least 3 frames of data, but when it has less than this number I get the exception

CSCore.MediaFoundation.MediaFoundationException occurred HResult=0xC00D36C4 Message=Interops::MFCreateSourceReaderFromByteStream caused an error: 0xc00d36c4, "The byte stream type of the given URL is unsupported.".

I want to be able to decode the frames as fast as possible after they are received over the rtsp stream and not have to buffer at least 3 frames before decoding.

Try to use the Ffmpeg implementation. Can't do anything about what's going on inside of the mediafoundation.
