  • MediaSPIP Player : problèmes potentiels

    22 février 2011, par

    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

  • Enhance the contrast of only a portion of an image using FFmpeg ?

    27 septembre 2021, par isend

    I am able to enhance the contrast of a whole image with the following command using FFmpeg eq filter :

    


    ffmpeg -i input.png -vf eq=contrast=2 -c:a copy output.png


    


    But can I enhance the contrast of only a portion (say, the second quadrant) of the image using FFmpeg ? I checked another post regarding how to apply a filter only on a certain duration of a film. Can I somehow insert something like enable='between(x,0,10)*between(y,0,10)' into the code above for my purpose ? Thanks.

    


  • Using FFMPEG to add pillar bars

    10 février 2021, par Ewok BBQ

    I have transferred some film to video files from 16mm (native 4:3). The image looks great.

    


    When I scanned them, I scanned to a native 16:9. As I overscanned them, I got the entire height of the frame, which is what I want. But it also got the soundtrack and perforation. But I want to go just to the frame line on the sides as well.

    


    I can CROP the image down with FFMPEG to remove the information outside of the framing I want [-vf crop=1330:1080:00:00].
I know this will result in a non-standard aspect ratio.
This plays fine on a computer (vlc just adapts to the non-standard).

    


    But for standardized delivery, I would love to keep the native 1920x1080 pixels, but just make everything outside of the centered 1330:1080 black.

    


    Is there a way to specifically select where the pillar bars are ?

    


    I really want to re-encode the video as little as possible.

    


    In that vein, does anyone have a better tool than -vf crop as well ?

    


    thank you very very much.

    


  • FFmpeg side by side video (widescreen) and play each video one by one

    6 mai 2020, par Knide

    new to ffmpeg, I've already did this to combine 3 or more videos that I have into 1 video :

    



    ffmpeg -i left.mp4 -i center.mp4 -i right.mp4 -filter_complex "[0:v:0][1:v:0][2:v:0]hstack=inputs=3" -c:v libx264 -tune film -crf 16 -b:a 256k output.mp4


    



    Now what I am having trouble with is the videos have different play times (in seconds) what I want to achieve is have them all side by side (working with the code above) then have left.mp4 play first (with it's own audio) once done, center.mp4 plays (has own audio), and when done too, right.mp4 plays (has own audio) as well and the video is over.

    



    Can someone enlighten me on how to achieve this ? Thank you !
