ERROR information
If any error code is indicated in parentheses, a playback error has been generated. Each error code is displayed in its fixed
position. (The duration of error-code indication is short, because when an error is generated, playback of the next file is
automatically attempted.)
Description of error codes
FMT : The file cannot be recognized as having an MP4 file format.
DEC : Although the file is recognized as playable, the decoder could not decode the data of the file correctly.
CH
: The number of channels is not supported.
QNT : The quantization bit rate is not supported.
BPS : The bit rate is not supported.
FS
: The sampling frequency is not supported.
BOX : The file format is judged to be not supported upon analysis of the MP4 file.
PRF : The Advanced Audio Codec (AAC) is judged to be not playable.
MEM : The system failed to secure the amount of memory required for playback.
Possible causes for errors and how to diagnose
Possible causes for an FMT error
Possible cause 1: Impossible box size for the first box of an MP4 format file
How to diagnose: Check the binary data of the file with which an FMT error was generated. Consider the first 4 bytes at the
beginning of the file as the box size and check if the size is 0 or a value that exceeds the file size.
If the box size is 1, consider the 8 bytes from the 8th byte from the beginning as the box size. Check if the
size is 0 or a value that exceeds the file size.
How to check the box size:
For checking the binary data of the file, use the Binary Editor of the PC tools.
The figure below shows the binary data of an MPEG4 file:
Possible cause 2: Failure in data reading during file analysis
How to diagnose: Check the ATA error log on the Debug screen.
How to check the ATA error log:
Display the ATA error log page by pressing [ESC], [DISP], [2], then [DIG/ANA], in that order.
The first 4 digits denote date, and the next 6 digits denote time. Check if the date and time match those when an error was
generated during AAC playback.
You can switch between Writer and HDD data, using [FRM/TIM]. Switch according to the type of medium being played back.
For USB, there is no log for reading errors.
BOX size
BOX name
With this file, the first box is an "ftyp" box, and its size is 0x18 bytes (the figure in the frame in red).
In a case of an FMT error, the first box size is 0 or a value that exceeds the file size (impossible value for the MPEG4 file format).
If the box size is 1, the data that are framed in dotted green lines in the above figure are treated as the box size.
