Hi, I would like to read AAC (Advanced Audio Coding MPEG format, *.m4a) tags, like iTunes does for example. I tried to check whether the format was similar to mp3 tags (id3 tags) however it's not at all the same. When opening a m4a file in stream mode and reading from start the structure is the following: \0\0\0 ftpyM4A \0\0\0\0MīŋŊA mp42isom\0\0\0\0\0\x01?\fmoov\0\0\0lmvhd\0\0\0\0 I also tried to seek from the back with no more success. The tag is likely compressed somehow. Does anyone know or have a clue how to read the tag and eventually how to play it ? (using TMediaPlayer or anything else) Thanks for your help, Dave
