Doesn't support wav files completely - incorrect time length reported

[nemo]

(FFmpeg <- LAVFilters <- MPC-HC)

It doesn't report the time length correctly on some wav files.

Example: ​https://mega.nz/#!YuomER6Y!YNkShluWwT47YI085AS170xTbV_seFFfpbtC_7tLMfU
Time length is 11:42 according to VLC.
MPC-HC reports itime length as 03:43 however when it reaches that time it continues to play.

The example was downloaded 2017-08-18 and is free this month.

"This is ac3 muxed in a wave container (if you look at the file in an hex editor, you will find many 0x00 in it (this is also the reason why this file is so compressibly); also, there seems to be an endianness swap on the ac3 data, but I actually don't know the specification of ac3 in wav). The 11:42 reported by VLC is also wrong: The real length is 3:24.768. This seems to be a bug in ffmpeg (or a limitation of ac3 in wav) and should be reported there. LAVFilters will inherit the fix for it (if it gets fixed)."

Does ffprobe also report the wrong length? All the various other tools have not a lot of meaning for ffmpeg itself.

Please reopen this ticket if you can provide the FFmpeg command line and the complete, uncut console output that show the issue you see and if the issue is reproducible with current FFmpeg git head.

I'm unable to get it to work. No matter what I do all I get is "access denied" in the console.
Could you please do it instead?

I don't think this is a valid ticket, a useful sample can be downloaded from ​http://www.mysurround.com/test/TestMySurround-en.dbr.wav.zip
