Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -

Building my JAVA parameter array for FFMPEG
29 janvier 2016, par user3541092FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)Machine : Amazon Linux t2.micro (free tier)
Sample File : sample_iTunes.mov
Sample File URL : https://support.apple.com/en-us/HT201549I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().
ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -yNOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().
String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
+ "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
p = Runtime.getRuntime().exec(_ffmpegCommand);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.
The following string array works :
try
{
String[] _params = {"ffmpeg",
"-i",
String.format("%s", _inputFile),
"-pix_fmt",
"yuv420p",
"-c:v",
"libx264",
String.format("%s", _outPutFile),
"-y"};
p = Runtime.getRuntime().exec(_params);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}
catch (Exception e) {
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :
try
{
String[] _params = {"ffmpeg",
"-i",
String.format("%s", _inputFile),
"-pix_fmt",
"yuv420p",
"-c:v",
"libx264",
"-vtag", // <---- New
"mp42", // <--- New
String.format("%s", _outPutFile),
"-y"};
p = Runtime.getRuntime().exec(_params);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}
catch (Exception e) {
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
