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.

Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

}FinalOutput.mpeg has the same frames as output.mpeg
I have several TransportStreams to process and everyone has a frame differencesomeone can help me to solve the problem ?
I need FinalOutput.mpeg to be aligned frame by frame with the original and necessarily the video must impress the timecode.
a possible solution would also be a replace "damaged" frame but I can not find out how to replace the skipped frames

Running ffmpeg command on Android results in "Unable to find a suitable output format for ' -map 0:v:0 -map 1:a:0'"
5 juin 2017, par Akash DubeyI am using this command for replacing audio of video and genrate new video having new audio. Here file1 is my video.mp4, file2 is my audio.mp3 and output would be the output.mp4 :
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};Below is My code :
private void changeAudioofVideo(String selectedUri, String videoPath) {
String[] complexCommand;
File f = new File("/storage/emulated/0");
if (!f.getParentFile().exists())
f.getParentFile().mkdirs();
if (!f.exists())
try {
f.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
file1 = new File(videoPath);
if (file1.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
file2 = new File(selectedUri);
if (file2.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
String rootPath = f.getPath();
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};
FFmpeg ffmpeg = FFmpeg.getInstance(this);

RTP packets detected as UDP
8 juillet 2024, par fritzHere is what I am trying to do :



WebRTC endpoint > RTP Endpoint > ffmpeg > RTMP server.



This is what my SDP file looks like.



var cm_offer = "v=0\n" +
 "o=- 3641290734 3641290734 IN IP4 127.0.0.1\n" +
 "s=nginx\n" +
 "c=IN IP4 127.0.0.1\n" +
 "t=0 0\n" +
 "m=audio 60820 RTP/AVP 0\n" +
 "a=rtpmap:0 PCMU/8000\n" +
 "a=recvonly\n" +
 "m=video 59618 RTP/AVP 101\n" +
 "a=rtpmap:101 H264/90000\n" +
 "a=recvonly\n";



What's happening is that wireshark can detect the incoming packets at port 59618, but not as RTP packets but UDP packets. I am trying to capture the packets using ffmpeg with the following command :

All I get is a blinking cursor and The stream.mp4 file is not written to disk after I exit (ctrl+c).



So can you help me figure out :



- 

- why wireshark cannot detect the packets as RTP (I suspect it has something to do with SDP)
- How to handle SDP answer when the RTP endpoint is pushing to ffmpeg which doesn't send an answer back.







Here is the entire code (hello world tutorial modified)
