回答1:
AcmNotPossible is an error code returned by the acmStreamConvert Windows function, which calls into the MP3 ACM codec. This error likely indicates either an invalid MP3 frame, or that you have passed in too many frames at once. How sure are you that you are getting whole MP3 frames? It is a good idea to debug problems like this by also writing the data you receive to an MP3 file and then checking that can play as expected.
