• Bulk Conversion Of Kubuntu Master Video Folder Using FFmpeg ?

  12 janvier 2019, par Sarah Szabo

  I have an old archive of videos (Around 400GB/1024 files) that are heavily structured due to the program that created them at the time.

  There is a single folder called master that contains many other folders for specific events that were recorded. I was thinking of using for i in *.vob; do ffmpeg -i "$i" "${i%.*}.mp4"; done (From another SO user’s answer on another question), but this is insufficient since the .vob files aren’t all in the master folder are are instead in different folders in master.

  Furthermore, the .vob titles are nonsense (And even worse overlapping ! Video 1 (In Folder 1), Video 1 (In Folder 2) so they can’t all be named the same thing in the same folder if I joined all of them.

  My question is can I do a tree traversal of master using a script (I’m running KDE) that takes each .vob files and converts it using somthing similar to for i in *.vob; do ffmpeg -i "$i" "${i%.*}.mp4"; done in master, but with the name of the folder instead of the name of the file ?

  So, if we were in the Assault On The Control Room folder and converted Video 1 and Video 2, could this output Assault On The Control Room 1 and Assault On The Control Room 2 and move the converted file to /somefilepath/master2 that contains all the converted files ?

  The labels would obviously be set using ffmpeg and a for loop, but my scripting skills aren’t up to this task yet.

• Having trouble with color code in batch file

  23 juin 2022, par Lary David

  I'm trying to only have ffmpeg progress to be colored, but for some reason when I terminate or go full-screen this monstrosity occurs :
Issue

ECHO.

pause


  


  Also, would be helpful if my code needs some cleaning up.

  


• mp4 generated using MediaMuxer doesn't play in ffmpeg

  7 février 2019, par APD

  I need to generate an mp4 video from the raw h264 bitstream only (hence don’t have any audio channel). To do the same, I used the MediaMuxer APIs from Android. The output mp4 videos that got generated, seems fine and are playing well on VLC media player. But the generated videos don’t play on chrome browser (on Ubuntu machine) and same is the case with ffmpeg.
  Other thing that I noticed is that, the mp4 generated with Android devices greater than Nougat (i.e., Oreo and later) are fine (i.e., they play on Chrome browser and ffmpeg also plays it well), however those generated from devices before Oreo, have this problem.
  Has anybody observed such a behavior and what can be done to handle this on Android-devices before Oreo ?
