Please test this 5.1 HE-AAC streams

What's wrong with them, why they are not playable? Can anyone analyze this bitstreams (does they compatible with AAC specification) :thanks:

i can only report what fooplayer say "Maximum number of scalefactor bands exceeded" neither nero showtime play these files dunno what this means :confused: BHH

What method did you use to create both files? And did you really mux the your .AAC stream/file into the MP4 (M4A) container, or did you just re-name the file extension? Cheers

The files are definitely not playable. mplayer errors __51.m4a.aac: FAAD: Failed to decode frame: Invalid number of channels FAAD: error: Maximum number of scalefactor bands exceeded, trying to resync!
