    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • How do I generate a color screen for the duration of an MP3 in ffmpeg ?

    25 février 2019, par yaggelee

    I have successfully generated a blue screen to add to an mp3. But, I have always needed to include the length of the clip to match the mp3. When I don’t include a timecode it continues to generate footage until I cancel the command.

    ffmpeg -f lavfi -i color=blue:s=1920x1080 -i input.mp3 -t 00:02:08 output.mp4

    How do I specify that I only want color generated during the length of the mp3 that I am adding ?

    ffmpeg -i <.jpg> -i <.mp3>

    This worked too but I don’t want to rely on a jpeg file.

  • FFMPEG - How to get a blur effect, without altering the color white ?

    17 août 2016, par Hugo

    I need a picture, with blur effect background. I found the code works, but, the white color of the photos is lost ( only happens with white color)...

    Step1 : ffmpeg -i eyes.jpg -s 640x360 -qscale 1 bg.jpg
Step2 : ffmpeg -i bg.jpg -filter_complex "[0:v]crop=640:360:0:0,boxblur=20[fg] ;[0:v][fg]overlay=0:0[v]" -map "[v]" -qscale 1 bg.jpg -y
Step3 : ffmpeg -i bg.jpg -i eyes.jpg -filter_complex "overlay=(main_w-overlay_w)/2 :(main_h-overlay_h)/2" -qscale 1 result.jpg

    Original photo :
    see original photo

    Result (white color is lost)
    see result photo

    Please I need help (The white color should remain).

    Thank you very much,
    Greetings,

  • ffmpeg with background color

    25 mars 2019, par NAG

    This command works nice with some GIF but with some others return a error :

    ffmpeg -f gif -f lavfi -i color=FFFFFF -i animated.gif -y 
    
   -filter_complex "[0][1]scale2ref[bg][gif];[bg]setsar=1[bg];[bg][gif]overlay=shortest=1"
    
   -pix_fmt yuv420p -movflags frag_keyframe+empty_moov -movflags +faststart
    
   -crf 20 -b:v 500k -f mp4 animated.mp4

    Error :

    [libx264 @ 0x55e79dc7e3c0] height not divisible by 2 (1400x933)
    
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0
    
- maybe incorrect parameters such as bit_rate, rate, width or height

    Some help to fix it maintaining the background color functionality ?
