  • 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".

  • ffmpeg - Making a Clean WAV file

    24 septembre 2016, par Edward

    I’m looking to batch convert a number of files to audio files using ffmpeg for a game called Star Wars: Jedi Knight: Dark Forces II. The problem I’m having is that ffmpeg seems to be doing something that does so that Jedi Knight can’t play the sound file.

    Jedi Knight accepts plain old PCM WAV files of various ranges, from 5khz to 96khz, 8 and 16 bit, mono and stereo. This sounds plain and simple. Except for that if one were to create a WAV file using MS Sound Recorder, Jedi Knight could not play it. Speculation was that it added something extra to header or something. But it can play a WAV file created by Audacity, GoldWave or ModPlug Tracker to name a few.

    So why not ffmpeg ? Am I using the wrong codec or params ? I took an original sound file from the game and performed the following :

    ffmpeg -i "orig_thrmlpu2.wav" -f wav -acodec pcm_s16le -ar 22050 -ac 1 "ffmpeg_thrmlpu2.wav"

    The ffmpeg version does not play in the game. ffprobe shows that the ffmpeg version has some Metadata which the original doesn’t have. What params should I use to try and get the same WAV format as the original ? Mind you, -ar, -ac and bits aren’t the important parts.

    Here are the files for you to examine : http://www.edwardleuf.org/Games/JK/thrmlpu2.zip

  • colors messed up (distorted) when making a gif from png files using ffmpeg

    13 novembre 2019, par wxyz

    I have a sequence of png images : image_00.png, image_01.png, image_02.png, etc. I want to convert them to a gif, so I tried the command

    ffmpeg -i image_%02d.png video.gif

    Unfortunately, the resulting gif has distorted colors. More specifically, it added a weird sort of yellow haze around some objects in the video.

    I also tried using the command above with all possible pixel format options (which I determined using the command ffmpeg -h encoder=gif) : rgb8, bgr8, rgb4_byte, bgr4_byte, gray, pal8. For example ffmpeg -i image_%02d.png -pix_fmt rgb8 video.gif. Unfortunately, all of the resulting gifs had some sort of color distortion.

    I also observed that this distortion does not occur if I convert the images to mp4 instead of gif. However, if I try converting that mp4 to a gif, I end up with the distortion again.

    How can I produce this gif without color distortion ?
