Taille des images et des logos définissables
9 février 2011, parDans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.
Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...) -
Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

<?php
?>so i ask some one he told me the exec stop php script and never give me
You can't get the progress directly if you are using exec, because the php script is stopped until ffmpeg closes. (Because exec returns the whole execution output)
You should use popen, for being able to get the output from the process in real time (without reading any file) for parse and show the progressbar
Here is a example for get the output:
When you get the progress info from ffmpeg, you can use your code for parse it and show your progressbarthis is my popen script
<?php
$handle = popen ("ffmpeg.exe -i files/fz.mp4 -ab 192k files/vdf.mp3 2>&1 ", 'r');
$handles = (string)$handle;
$line = "";
while (false !== ($char = fgetc($handle)))
{
if ($char == "\r")
{
// You could now parse the $line for status information.
echo "$line\n";
$line = "";
} else {
$line .= $char;
}
ob_flush();
flush();
}
pclose ($handle);
//get duration of source
preg_match("/Duration: (.*?), start:/", $handles, $matches);
$rawDuration = $matches[1];
//rawDuration is in 00:00:00.00 format. This converts it to seconds.
$ar = array_reverse(explode(":", $rawDuration));
$duration = floatval($ar[0]);
if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
//get the time in the file that is already encoded
preg_match_all("/time=(.*?) bitrate/", $handles, $matches);
$rawTime = array_pop($matches);
//this is needed if there is more than one match
if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
//rawTime is in 00:00:00.00 format. This converts it to seconds.
$ar = array_reverse(explode(":", $rawTime));
$time = floatval($ar[0]);
if (!empty($ar[1])) $time += intval($ar[1]) * 60;
if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
//calculate the progress
$progress = round(($time/$duration) * 100);

HEVC with alpha [closed]
3 mai 2024, par foxhableI trying create HEVC with alpha video from png images through ffmpeg.


When i try, it outputs a video that works, has a transparent background and opens in QuickTime, but does not open in Safari. Then i try creating in prores 4444 codec and convert from macOS Context Menu -> Encode Selected Video Files with HEVC 1080p and Preserve Transparency. It has work - video with transparent background, open in QuickTime and in Safari.


So i tried understand what a difference in meta data and only what i find its working video has
HVECencoder, but not working hasLavc61.5.103 hevc_videotoolbox. Can i somehow programmatically or from utilities like ffmpeg create video with HEVC With alpha, which working like from macOS context menu ? macOS context menu doesnt fit because i cant compress or create many videos

Unable to 'make' android ndk project - build fails : [build-openh264-x86] Error 2
18 décembre 2015, par NoobNinjaI’ve attempted these two fixes I’ve found while researching the issue :
android update project --23 --/Users/ajswann/Downloads/android-sdk-macosx
make OS=android NDKROOT=/Users/ajswann/Downloads/android-sdk-macosx TARGET=android-19 ARCH=x86 clean...however neither seems to resolve the issue.
Any input/suggestions are appreciated.
P.S.
I’m running OSX - could this be an issue with attempting to run an x86 architecture on a 64 bit machine ?
