Are you using an AVParser to parse the individual frames before you decode
them? If you don't do that, you will get the above errors, which basically
imply that incomplete frames, data not indicating the start of a frame, or
otherwise corrupt individual units were provided to the decoder. Using an
AVParser will solve all that.
