Hello,
This patch aims to fix a problem I've noticed while working with AEA (Sony ATRAC1 comtainer) files.
Right now FFmpeg always exits with an "Input/Output error" when dealing with AEA files.
This patch solves that issue by returning AVERROR_EOF once the end of file is encountered, instead of always returning AVERROR(EIO).

I am sending this patch again because of an incorrect mime type of the first one.

Best regards,Asivery
