All of you are thinking about file comparison in the sense file count but my need is not that.
Actually source directory consists of 15000 files of which 11000 are mp3, 2000 are m4a, 100 are flv, 500 are jpg, 100 are gif, 100 are gif, 100 are txt, 200 are avi files.
I have transcoded 9000 files to opus and remaining to m4a files using batch encoder and it maintained directory structure same as source and renamed output files according to my selection.
I am suspecting that some of files were not transcoded at all and some output files play back length are not same as their sources. I want a list of files which are not transcoded at all with path in a text file or if possible those files in a another directory. Second most important I want list of files which are transcoded less in play back length than source and if possible I want these files also in another separate directory.
Remember that output file may be created but don’t have same play back length as source.
I think that this post is not related to file management but related to multimedia.Please examine some toils like mediainfo, mp3tag etc., and give suggestions.
