Creating a movie from multiple .png files
21 octobre 2014, par QuantumFoolI’ve got quite a few .png files, and I need to create a movie out of them. So, I’m going through this tutorial which uses ffmpeg :
http://www.miscdebris.net/blog/2008/04/28/create-a-movie-file-from-single-image-files-png-jpegs/
When I go to type the first line (sudo apt-get install ffmpeg), in Terminal and enter my password as appropriate, I get :
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ffmpeg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ffmpeg' has no installation candidateThat’s funny ; I installed the latest version manually this morning ! Anyway, I proceed with the instructions assuming ffmpeg is installed properly (I’m looking at the file where it downloaded to, so that can’t be the issue) :
cd Downloads
cd python-meep
cd Images
ffmpeg -qscale 4 -r 20 -b 9600 -i Image%03d.png movie.mp4To my surprise, I get :
ffmpeg: command not found
I just installed it ! Furthermore, I dragged my manual installation folder into the very same directory with the pictures ! What’s going on ?
Thanks !

ffmpeg set subtitles track as default
21 novembre 2016, par blörkBy adding an .ass subtitles track to an mkv video with ffmpeg, it isn’t set as default track, so on playback you have to manually turn on subtitles. Is it possible to set the default flag for the subtitles track ?
ffmpeg command used :
ffmpeg -i video.mp4 -i subtitles.ass -c:v libx264 -preset veryslow \
-pix_fmt yuv420p10le -c:a copy -c:s copy output.mkvNote that I want to keep .ass subtitle format, not convert the subtitles to mov_text like suggested in this similar question :
How to set default streams with ffmpegThere is the possibility to set the default flag afterwards with mkvpropedit like this :
mkvpropedit output.mkv --edit track:s1 --set flag-default=1
But is it possible to do this directly with ffmpeg ?
