• Is it possible to convert all video files in subdirectories on google drive using ffmpeg & rclone ?

  24 avril 2020, par rms

  Currently I'm using this code whereby rclone fetches 1 file from my google drive, converts it using ffpmeg on a server and moves the converted files to the same folder. It's shown as below.
Step 1 is generating a list over which rclone can iterate over and the conversion process begins with the second script in step 2

  



  step 1

  



  rclone lsf "gdrive:/folder" --files-only > list.txt


  



  step 2

  



  while read file; do
    rclone copy "gdrive:/folder/""$file" . -P
    ffmpeg -i "$file" -vf scale=-1:540 -vcodec libx265 -crf 26 "${file%.*}.mkv" null
    rm -f "$file"
    rclone move . "gdrive:/folder/" --exclude list.txt -P
done code>

  



  However, some sub directories have nested videos to convert which would rather take a long time if I'm to do it for every folder. This brought me to my question whether it's possible to modify the above process to work with subdirectories.

  



  I've tried rclone lsf to generate the list recursively using the -R flag but ffmpeg doesn't seem to read the file from the list to make it work. Is there a way to make this work with some tweaking possibly ?

  


• Windows : How to build X264.lib instead of .dll

  25 juin 2015, par user1884325

  I downloaded the X264 source and installed mingw.

  Step 1 :

  Executed this in the MINGW bash :

  ./configure —disable-cli —enable-shared —enable-win32thread -
   extra-ldflags=-Wl,—output-def=libx264.def

  and then ’make’

  Step 2 :

  Renamed the libx264-142.dll to libx264.dll and Opened up VS2012 Command Prompt and executed this :

  LIB /DEF:libx264.def

  which gave me libx264.lib and object libx264.exp

  Step 3 :

  Included the lib file in a VS2012 project which uses the X264 API.

  Problem :

  When I start the project I get the following error message :

  "The program can’t start because libx264.dll is missing from your computer"

  Question :

  Why is it looking for the dll when I’m linking the static library in ?

  How do I resolve this ? I would like to build a static X264 library which I can link in with my project.

  EDIT :

  I just had to put the dll in the same directory as the project executable.

  However - My question still stands : How do I build a static x264 library ? So I don’t need the dll ?

• Ffmpeg PNG image sequence into 360 video

  5 février, par Irmak Ozarslan

  I'm trying to make a PNG sequence I got from blender(already in equirectangular format, same properties all files) into 360 equirectangular video for projection mapping. My files have 2 step frame rate resulting in file names such as 002-004-006.... How is this done with ffmpeg ? I'm total noob with this program :) Thank you.

  


  I checked ffmpeg website, however for 360 format with filenames that does not have one step like 01-02-03, instead 2 steps like 02-04-06, I did not really understand how to convert my 7000 PNG images into 360 video.
