    • [DH] libavformat/mov.c
  • FFmpeg drawtext=enable'between(t,0,5)' not working

    24 juillet 2018, par Avani

    I’m trying to draw text on a video at different time intervals using ffmpeg. Below is my instruction :

       ffmpeg -i input.mp4 -vf "drawtext=fontfile='C:\arial.ttf':text='Text1':x=5:y=20Ûmax_glyph_a:fontsize=24:fontcolor=yellow:box=1:boxcolor=black@0.5:boxborderw=5:enable='between(t,0,20)', drawtext=fontfile='C:\arial.ttf':text='Text2':x=100:y=20Ûmax_glyph_a:fontsize=24:fontcolor=yellow:enable='between(t,5,20)', drawtext=fontfile='C:\arial.ttf':text='Text3':x=200:y=20Ûmax_glyph_a:fontsize=24:fontcolor=yellow:enable='between(t,10,20)'" output.mp4

    I’m trying to draw text in a horizontal line and I want only Text1 for the first 5 seconds, and then Text2 starting from 5 seconds to 20 seconds, and Text3 starting from 10 seconds till the end.

    When I do this, my first text stays for about 15 seconds and the last two show up in the last 4 seconds of the video. Is there something wrong with my instruction ? Am I using the enable between correctly ?

    Below is the Log for ffmpeg -i input.mp4 -vf showinfo -vsync 0 -f null - :

  • How to swap package configuration for environment

    24 juillet 2018, par Finn Maunsell

    I’d like to change the location that I get ffmpeg from for my anaconda environment. The problem has occured because I want to use the ffmpeg configuration for my base system instead of the configuration meant for the environment.

    If I use ffmpeg in ubuntu bash then I get this for my active environment :

     ffmpeg version N-91510-gd134b8d Copyright (c) 2000-2018 the FFmpeg developers
     built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.10) 20160609
     configuration: --prefix=/home/notebook/ffmpeg_build --pkg-config-flags=--static --extra-cflags=-I/home/notebook/ffmpeg_build/include --extra-ldflags=-L/home/notebook/ffmpeg_build/lib --extra-libs='-lpthread -lm' --bindir=/home/notebook/bin --enable-gpl --enable-libaom --enable-openssl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree

    and for non-environment :

    ffmpeg version 3.4.1 Copyright (c) 2000-2017 the FFmpeg developers
     built with gcc 4.8.2 (GCC) 20140120 (Red Hat 4.8.2-15)
     configuration: --prefix=/home/notebook/anaconda2/envs/tensorflow --disable-doc --enable-shared --enable-static --extra-cflags='-Wall -g -m64 -pipe -O3 -march=x86-64 -fPIC -I/home/notebook/anaconda2/envs/tensorflow/include' --extra-cxxflags='=-Wall -g -m64 -pipe -O3 -march=x86-64 -fPIC' --extra-libs=
    '-L/home/notebook/anaconda2/envs/tensorflow/lib -lz' --enable-pic --enable-gpl --enable-version3 --enable-hardcoded-tables --enable-avresample --enable-libx264

    Solving this will allow me to use the 2nd ffmpeg installation in my conda environment.
