I have thousands of video files to check/verify if they have an error or a warning. A firm just digitized them over old tapes (VHS, Umatic ...) All these videos are in mp4 format and i want to check them automatically with a software. After a small search i found this website (http://videofilechecker.com/), but there is no trial version of the software so i could not test it with my video files. Then i saw that the software is using ffmpeg to verify all these videos. In my second search i found this question in superuser. (How to check the integrity of a video (avi, mpeg, ...) file?).
In that question the answer is:
ffmpeg.exe -v 5 -i file.avi -f null - >error.log
i checked the error.log and it was completly empty (Probably there wasn't an error in the video)
but i researched the documentation of the ffmpeg and found some another stuff like:
ffmpeg.exe -v error -i file.mp4 -f null - >error.log
but then i got an error:
Unknown input format: null Failed to set value 'null' for option 'f': Error number -22 occurred
If i try with
-v 5 there is no error at all, but in the documentation it is written with
With my limited knowledge with video verification, i am not so sure with which options should i use with ffmpeg to verify all these files. Also my next problem will be to write a batch script in windows, which is going to check all the files one by one and if there is an error it will write it out to a log file with the file name in it. Does someone has any software idea or script to verify these videos?
