  ffmpeg : replace custom channel_layout code with an SpecifierOpt based one
  This is cleaner and allows fine tuning which stream the option is applied to.

• ffmpeg timecode based on filename

  9 mars 2023, par marven

  I have xxxxx videofiles that need to get a timecode (for working in premiere)
The filenames are all like this 2023-03-08 12.59.59 AndSomeRandowNumbers.
Is that possible with ffmpeg ?
Or if that is not possible : can ffmpeg use an other date from the metadata and use that as timecode (with exiftool is possible to use the filename and write it as creation date, and other, but not as timecode) ?

  


  ffmpeg -i file.mov -map 0 -map -0:d -c copy -timecode 02:10:22:33 outputfile.mov
that is the code that works to change the timecode to 02:10:22:33

  


• Is there a way to pick up a file based on the date modified in batchfile or direct cmd : Windows

  10 octobre 2019, par A Person

  My goal is to be able to pick up files based on the date modified. The files has same name with the ending string being different as it has date and time stamp on the file. I’m trying to either use that value or use the actual date modified/created value to pick up the correct file.

  my script so far picks up every video file from one folder and find its matching audio channels and merges them together in ffmpeg. However sometimes there are multiple version of that file. i want to be able to pick up the new file and use that in the transcoding.

  My Research : (Tried these methods and tried to adapt but was not able to)

  https://askubuntu.com/questions/61179/find-the-latest-file-by-modified-date

  Batch file to copy the newest file created (not modified)

  Example of file names.

  BA_MUS_006615Highc450277201903201834100272.m2v
  This can have a pair with the beginning being same just the ending different. BA_MUS_006615Highc450 this part remains same with the identifier being Highc450 and the file name changing. the file name is BA_MUS_006615 this string can change unless it a new version of same file where only the date portion and time change. 277201903201834100272. Date starts after 227 the one above is shown as 20190320 and time is 183410.

  This time reflects to actual time of the date modified tab in windows and is slight off by a minute or two as the time is stamped when the file enters the software not exiting.

  Is there any help i can get on this. If you require more information please let me know.

  The code i am using to match the file is using a software called RoboTask, where is like a programming but with GUI. Then the file calls cmd to run the ffmpeg and then exits cmd to go back to picking the next file.

  Thanks.

  EDIT

  Goal : Be able to find a file that matches the exact same name for example

  BA_MUS_006615

  then when it picks up all the files that has the same name - it find the file which is the newest and assigns that to a variable.

  The code i am currently using is one made by Ben Personick (https://stackoverflow.com/users/3985011/ben-personick) which is Finding File Matches & Variable Assignment using a .BAT Script
