• Error : "from : can't read /var/mail/moviepy.editor" How to resolve ?

  23 mai 2017, par batman_rising

  I have a script using which I am editing a video, (extracting 10 clips from a video and then simply concatenating them), I am using moviepy python module as well as ffmpeg

  The script works perfectly when I run it from terminal,

  Now I wanted to run the same script on startup, so I added a path in /etc/rc.local
sudo python /home/startlord/myProject/run.py but the code doesn’t work.

  also, I tried another approach,
  sudo nano /etc/init.d/testRun and created the script executable sudo chmod 755 /etc/init.d/testRun
  but when I wanted to start the execution sudo /etc/init.d/testRun start I was getting this error

  from : can’t read /var/mail/moviepy.editor

  what should I do now ! I am using UP-board, please help, I am not from computer science background.

• FFMPEG filter_complex wih speedup and subtitles and scaling

  11 décembre 2015, par Sambir

  Hi I am trying to convert a file to a specific framerate and remove any jittering, jumping of the screen. I also try to boost the volume and add a subtitle overlay. I get an error with the curent line than it is not allowed to use complex_filter in combination with vf and af. as an extra I also would like to add text in the left corner (this i did not try yet) and would want the screen to be sized to full hd (changed scale to 1920:1080 but no succes).

  ffmpeg -i movie.mp4 -r 25 -filter_complex "[0:v]setpts=0.959*PTS[v];[0:a]atempo=1.0427[a]" -map "[v]" -map "[a]" -vf subtitles=sub.srt,scale=1920:1080 -af volume=2 -strict -2 -preset veryfast movie_new.mp4

  Got it !

  New :

  ffmpeg -i inside.mp4 -r 25 -filter_complex "[0:v]setpts=0.959*PTS[i];[i]scale=1920:1080[j];[j]subtitles=inside.srt[k];[0:a]atempo=1.0427[p];[p]volume=2[q]" -map "[k]" -map "[q]" -strict -2 -preset veryfast inside_new.mp4

  But now there is a new issue. Subs out of sync :P is there a easy fix for this or do i first need to encode without subs then resync then encode with subs ?

  found this link by the way Subtitle Resync Tool

  moviespeed is changed by 0.959. is there a calculation i can do to adjust the subtitles by x miliseconds ?

  EDIT : Got the subtitles fixed with subtitle workshop. Was just a small setting to change which directly shifted all the text :)

• How to convert raw video file (.ign) to .mp4 ?

  30 octobre 2014, par aizaaz

  I want to get videos out of Aakash iTutor (education tablet with Android 4.1) to store them on my PC. I found out where the videos actually are in the educhip (memory card). The videos had their extensions removed and I simply started renaming them but I couldn’t find the extensions.

  • Can I get the app’s internal video player to convert it ?
  • Or can I convert an unknown format video i.e. .ign to mp4 or something playable ?

  In case that’s not possible, can you help manually screen-record those videos at at least 30fps with soundcard sound (Screen Record Pro showed that the content was secure and couldn’t be recorded.)

  Another player (.rec ) does not work with 4.1 Android.

  Also, there are 4 folders in the educhip and all the folders (including the one in which these videos with no format are placed) have a lot of small files around (300B to 40kB) that too with no extension.
