• How do I batch cut videos ? [closed]

  12 février 2024, par EngineerJack

  I've searched for a while on Google, but haven't found a good solution.

  


  I have multiple videos that I want to cut parts from, so I would like to figure out how to batch cut them so I can figure out each video, then cut them all at once.

  


  I assume I'll use the terminal or powershell, and use commands, write down the info for each video in a file (like a script) then call on that file so they process one after another from that script.

  


  I know that I can do this one-by-one with the code below, but I would like to know how to use the following code for multiple videos as I described above.

  


  ffmpeg -i "video.mp4" -ss 00:00:00 -to 00:00:00 -async 1 -strict -2 "cut.mp4"

  


  BUT, a program (preferrably freeware) that isn't a video editor, but one that I can put the "start" and "end" times, then add multiple videos, WOULD be preferred.

  


  Anyone who can help me with this, I'd appreciate it.

  


  I've tried searching for ways to do this using .bat and .ps1 files on Google, but without finding a good solution.

  


• Range selector for Video trimming

  28 février 2019, par VoidMain

  I am working on a project in which I have to trim a video. But first the user needs to select the video for trimming I have done a little digging around and have failed to find a suitable library. I need to implement just the UI that would let the user select the starting and ending point of the trim.

  (I need just the UI the data will be taken from that UI will be used in trimming the video using FFmpeg-android which is working properly)

  A library similar to this iOS layout would do the trick.

  Please, do let me know if you have any ideas ? or a better solution for it.

  Any help would be appreciated.
  Thanks

• Size Discrepany in the ‘du’ Command

  22 juin 2012, par Multimedia Mike — General

  I had a problem today while using the common Unix command ’du’. As a refresher, ’du’ stands for disk usage and is a handy tool for understanding how much disk space is being occupied.

  I think ’du’ is probably doing the right thing. The problem might be that I’m getting strange (read : 1/2 the expected number) when running the tool against directories on vmhgfs, the VMware filesystem.

  Science Project
  On an Ubuntu Linux VMware session, my home directory is on the main file system, which is ext4. The directory /mnt/hgfs is reported by ’mount’ to be of type vmhgfs and is shared with the host machine.

  Create a directory in the home directory and generate a 10 MiB file :

  mkdir /home/melanson/dir
  dd if=/dev/urandom of=/home/melanson/dir/random-file bs=1048576 count=10
  

  Create a directory on the shared drive and copy the same file :

  mkdir /mnt/hgfs/vmshare/dir
  cp /home/melanson/dir/random-file /mnt/hgfs/vmshare/dir
  

  Run ’du’ on each directory using the -k and -h options :

  du -k /home/melanson/dir /mnt/hgfs/vmshare/dir
  10244   /home/melanson/dir
  5120    /mnt/hgfs/vmshare/dir
  du -h /home/melanson/dir /mnt/hgfs/vmshare/dir
  
  11M    /home/melanson/directory
  
  5.0M   /mnt/hgfs/vmshare/directory
  

  I noticed this discrepancy when I was trying to pack a set of files (akin to ’tar’-ing) living in a directory in the shared location. I was going mad trying to understand why the original directory was only 2 MB as reported by ’du’ but the final packed file was 4 MB.

  To be fair, the man page for ’du’ succinctly states that the tool’s purpose is merely to "estimate file space usage".
