Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -

this is my code.



String s = " -i " + musicDbs.get(0).musicPath +" -vn -ar 44100 -b:a 192k "+ dir.getPath();
// s = -i /storage/emulated/0/Doto30/FX/Pishro_Ft_Hichkas_Divoone.mp3 -vn -ar 44100 -b:a 192k /storage/emulated/0/Doto30/.final_audio.wav
String[]cmd = s.split(" ");
 FFmpeg ffmpeg = FFmpeg.getInstance(context);
 try {
 ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
 @Override
 public void onStart() {
 }

 @Override

ffmpeg copy file while recording
5 mars 2015, par Bruno SiqueiraI am developing an Android app that records and live streams videos through the mobile camera.
Right now, I am toggling between both of them. I want to record and stream at the same time.While the file is being recorded, is not possible to stream using ffmpeg, because the MOV ATOM from the MP4 file information is not inserted in the file yet (it goes in the end).
Is there any way for the ffmpeg to :
- read the file successfully while it it being recorded ;
- listen to every change in the file, so it stream the new bytes of
information ; - in case I go for another solution, like copying the streaming bytes to a file, can I correct the file via ffmepg to correct any missing headers ?
Edit :
I decided to try a different approach by accessing the camera directly via command line using ffmepg. If it works, I can record the video and stream at the same time. I started trying the FFMPEG library for android : with the following code inside a MainActivity :
final FFmpeg ffmpeg = FFmpeg.getInstance(getApplicationContext());
try {
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {}
@Override
public void onFailure() {
}
@Override
public void onSuccess() {}
@Override
public void onFinish() {}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
Log.e("FFMEPG","error", e);
}
try {
// to execute "ffmpeg -version" command you just need to pass "-version"
ffmpeg.execute(" -y -f video4linux2 -s 320x240 -r 25 -i /dev/video0 /testing.mp4", new ExecuteBinaryResponseHandler() {
@Override
public void onStart() {
Log.d("FFMEPG","start");
}
@Override
public void onProgress(String message) {
Log.d("FFMEPG",message);
}
@Override
public void onFailure(String message) {
Log.e("FFMEPG",message);
}
@Override
public void onSuccess(String message) {
Log.d("FFMEPG",message);
}
@Override
public void onFinish() {
Log.d("FFMEPG","finish");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// Handle if FFmpeg is already running
Log.e("FFMEPG","error", e);
}
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
ffmpeg.killRunningProcesses();
}
}, 10000);And also giving the necessary permissions in the AndroidManifest.xml :
I am just trying to record a simple 10 seconds mp4 file from the camera, but I am getting the following error :

How can I fix this ffmpeg memory error on linux ?
15 janvier 2020, par JohnI installed ffmpeg on my server and I am trying to create a simple slide show of two images named sample1.jpg and sample2.jpg.
This is the command I’m using :
ffmpeg -framerate 0.1 -i sample%d.jpg -c:v libx264 -r 30 -pix_fmt
yuv420p out2.aviIt fails with the message :

From what I interpret from the error code. Its failing to allocate 3MB of ram. When I check my memory with free -m. It says I have plenty of free memory :
total used free shared buffers cached
Mem: 1024 863 160 2 0 577
-/+ buffers/cache: 286 737
Swap: 0 0 0I think I’m on Centos 6 x64 bit :
centos-release-6-10.el6.centos.12.3.x86_64
How can I get ffmpeg to make a slideshow of my images without running out of memory ?
