  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • How can I write to file with video state while paused in ffplay

    26 août 2014, par pixelearth

    Can anyone recommend a way to do what I need : I need to go through 2000+ videos and choose an accurate thumbnail frame down to the .xx decimal place.
    Ffplay works great for this, but it’s tedious to manually copy paste this value from the terminal into my database. It would be great if I could hit a key sequence or somehow trigger an event that would write information about ffplay’s current state (filename, location) to a file.

    Is there a way once the video is paused to somehow write to a file with the filename and location ?

  • ffmpeg rotate and resize

    23 août 2014, par user1321964

    I’m trying to resize a movie and to rotate it counter-clockwise using ffmpeg.
    I can achieve one or the other ok individually

    ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

    OR

    ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

    but if I try to do both, either-

    ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

    ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV

    OR

    ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

    ffmpeg -i rotate.MOV -s 406x720 toutp.MOV

    the final movie does not play, only audio, no video ; neither previewing in Finder, nor in Quicktime. More seriously once I have attempted to play it, I can’t then play any other movie whatsoever (only audio) - quicktime won’t quit, constantly need to force-quit it. The only way to then restore seems to be reboot OS-X

    This though does work -

    ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

    ffmpeg -i rotate.MOV -s 720x406 toutp.MOV

    but doesn’t do what I want - it stretches the movie in the wrong direction

    Any ideas ?

  • Elimination compression from videos generated from images using ffmpeg ?

    5 novembre 2011, par Magz

    So I'm using ffmpeg to generate videos from a series of images. Unfortunately every video I've generated so far becomes compressed about halfway through (these are about 10-30 second videos). I've tried a lot of different options, but here's an example and the resulting output.

    Any suggestions ?

    ffmpeg -minrate 5000k -maxrate 5000k -bufsize 1835k -b 5000k -s 480x480 \
    
-f image2 -r 10 -i 'dms-%05d.jpeg' output.flv
