  • FFMPEG Concat Dropping Frames

    16 mars 2015, par scientiffic

    I’m using FFMPEG to do the following two things :

    • create an mp4 given a set of images
    • compile mp4s to create a longer video (mp4)

    To create mp4s from images, I use the following command :

    ffmpeg -r 5 -i 'img%03d.jpg' output.mp4

    As far as I know, this creates a video with a framerate of 5fps.

    But when I try to compile mp4s, it seems like frames within each mp4 are being dropped.

    To create the compiled footage, I create a text file that points to all the mp4s that should be included in the compilation, e.g.

    file 'set1/output.mp4'
    
file 'set2/output.mp4'
    
file 'set3/output.mp4'
    
file 'set4/output.mp4'
    
file 'set5/output.mp4'
    
file 'set6/output.mp4'
    
file 'set7/output.mp4'

    Then I run the following command :

    ffmpeg -f concat -i input.txt -codec copy compilation.mp4

    The resulting video seems to drop 2-3 frames from each of the output videos.

    How do I ensure that the compiled video doesn’t drop any frames ?

    (For reference, I used the following tutorial : https://trac.ffmpeg.org/wiki/Concatenate)

  • compile the ffmpeg3.3 for Mac OS show ERROR : libmp3lame >= 3.98.3 not found

    4 mars 2018, par MR.PJ

    I use my mac to compile the ffmpeg3.3 for Mac OS according to https://trac.ffmpeg.org/wiki/CompilationGuide/macOS.I tried the first(which through Homebrew) and third(which builds it yourself) method,the first method is ok.

    But the third, compiling FFmpeg myself and Installing dependencies with Homebrew.I don’t know the meaning of this sentence enter image description here

    after this step :

    ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass \
    --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame \
    --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libopus --enable-libxvid \
    --samples=fate-suite/

    terminal show :

    RROR: libmp3lame >= 3.98.3 not found

    when I use locate libmp3lame.a,it is at ’/usr/local/Cellar/lame/3.99.5/lib/libmp3lame.a’.

    I also try --enable-libmp3lame --extra-ldflags=-L/usr/local/lib to solve,but it is no effect.

    How to solve thisERROR: libmp3lame >= 3.98.3 not found
