Comment (by cehoyos):
Iirc, I tested the following:
$ ffmpeg -i input out.wav
(ffmpeg's output will tell you the duration, but the duration of a wav
file is generally known.)
I also tested the following iirc:
$ ffmpeg -i input -acodec copy out.aac
$ faad out.aac
The duration of the resulting wav file was very similar to the duration of
the wav file produced by FFmpeg.
If you talk about video frames (it was not clear for me from your report),
it is even simpler:
The following command line tells you how many video frames a media files
contains and outputs every single frame as png:
$ ffmpeg -vsync 0 -i input out%3d.png
Please allow me to repeat my question: Why do you believe the file is 2:85
long?
