    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.
    Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

  • How can I automate video encoding using FFmpeg

    30 janvier 2020, par park joh

    I want to find the optimal encoding for a video using FFmpeg and looking for a script to automate that.

    there is VMAF (libvmaf) that helps us to measure the quality of the results, I look for a script or a way to use it to decide what is the best flags to encode each video based on libvmaf score.

    For example, I want to get a list of :
    FFmpeg (flag list and values), VMAF score, total size, average bitrate, max bitrate, min bitrate

    Then I would be able to choose the encoding flags based on that list and my bitrate preference.

    Do anyone know how to compose that kind of a script/ direct me to exist one (or existing flag of FFmpeg that I don’t know that do exactly that...)

  • Android : mp4 file plays when downloaded but when choosing "Video" player gets "Cannot play video"

    14 janvier 2014, par gview

    I've converted the video to an mp4 with ffmpeg using the h264 codec and AAC, and used the baseline profile.

    Videos are 540x360x250kbps

    I then ran qt-faststart on the file to move the atoms into the right order.

    I've stuck the file up on a wiki we use and created a link to it.

    My test phone is a Samsung Galaxy S3.

    When I browse to the page that has links to the mp4's on it, and I click on them, I get a popup window with 2 options : Internet and Video.

    If I download the videos using the "Internet" option, I can play them on the phone without issue.

    I've done other encodings with the main profile as well, and these also play fine. I thought that a powerful phone like the s3 would be able to handle the more advanced compression schemes available in h264, however I've also browsed the Android docs in regards to supported video formats, and it seems to state that only the "baseline" compression profile is supported.

    Regardless, what doesn't work is trying to use the "Video" option which I assume tries to stream the video.

    For the wiki in question, clicking on the link reveals that the content-type and content-length headers are being set :

    Content-Length  6175996
    
Content-Type    video/mp4;charset=UTF-8

    Clicking on the link with a browser invokes a player (Quicktime in most cases) that can play the mp4's.

    Is there more to having the file HTTP streamable beyond making a link to it ? Why won't my Android 4 play these files ?

    UPDATE :
    I decided to make a quick HTML5 page using the video tag, and the videos do play on both my Galaxy S3 and the latest IOS.
