• sudo checkinstall - installation failed

  18 décembre 2020, par Mathiem

  I'm trying to install ffmpeg on Raspbian by following these steps :

  



   cd ffmpeg
./configure --prefix=/usr
time make -j 8
cat RELEASE
sudo checkinstall


  



  but when I do the sudo checkinstall step, it gave me an error :

  



  pi@raspberrypi ~/ffmpeg $ sudo checkinstall -y

  Can anyone help me ? What can I do ? I'm not gonna lie, I'm a noob and I don't really know where to start, I tried 3-4 things but it didn't work.

  



  Thanks !

  


• Bash : Create copy of music files in different format and folder

  13 mai 2021, par Brett Sjoholm

  I'm trying to create a bash scipt to simply automate finding my flac files and creating an alac copy of them in a separate folder. Just so I have my little itunes folder. Want to automate because so many.

  


  So I find my flac folders within my Eminem folder....

  


  :~$ find /mnt/music/Eminem -type d -name *FLAC
    /mnt/music/Eminem/2009 Relapse FLAC
    /mnt/music/Eminem/1996 Infinite FLAC
    /mnt/music/Eminem/1999 The Slim Shady LP FLAC
    /mnt/music/Eminem/2000 Marshall Mathers LP FLAC


  


  Now instead of going into each folder and converting manually using something like

  


      ffmpeg -i track.flac -acodec alac track.m4a...


  


  How do I, within a bash script, take these multiple folders. Create an ALAC copy of the contents in /mnt/music/iTunes using FFMpeg ?

  


  New folder will be...

  


  /mnt/music/iTunes/Eminem/2009 Relapse ALAC/track.m4a


  


  All flac folders have FLAC at the end in the same folder structure.

  


  /mnt/music/Artist/Year Album FLAC


  


  I understand most of the locating, copying, converting, manually terminal command stuff but when it comes to putting it into a bash script. I don't understand how I take the output of each command and use it for another. The list of folder for example. Don't know how to automate doing all the steps for each.

  


  Kind of long winded but any help will be much appreciated. Even some videos you recommend for learning.

  


• ffmpeg xfade not working well with acrossfade

  7 juin 2021, par Richard

  I'm having trouble using xfade together with acrossfade.

  


  I have two videos t1.mp4 and t2.mp4 of same fps, resolution and so on. Both videos are 15 seconds long.

  


  Now I want a one-second fade transition in between.

  


  Without acrossfade,

  


  ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p" output.mp4


  


  after checking all the frames, the transition looks good. There are some overlapped frames with fading effect.
Please see below two consecutive frames.


  


  But the second part of the result has no audio, that's why I decide to use acrossfade.

  


  ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p;acrossfade=d=1" output.mp4


  


  Now it seems the transition effect is incomplete, there are less overlapped frames with fading effect, and the transition is sharp. Please see below two consecutive frames, same frame nubmer as above.


  


  What am I missing here please ?

  


   ffmpeg -i t1.mp4 -i t2.mp4 -filter_complex "xfade=transition=fade:duration=1:offset=14,format=yuv420p;acrossfade=d=1" output.mp4
