Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -
Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

Record Screen using ffmpeg doesn't work in tomcat server(Could not find codec parameters for stream 0)
4 septembre 2019, par Norhan MohamedI have the following problem,when I executed the below FFMPEG terminal command in command it prompt successfully.
C:\\ffmpeg\\bin\\ffmpeg.exe -f gdigrab -i desktop -c:v libx264 -analyzeduration 15M -probesize 15M -pix_fmt yuv420p -loglevel 99 C:\\ffmpeg\\bin\\video.mp4but I have a problem while running a command from a java web application.I used
runtime.exec(). It’s working fine at Netbeans. But not working at all after deploying on tomcat server.
Here is my code :String command = "C:\\ffmpeg\\bin\\"
+ "ffmpeg.exe -f gdigrab -i desktop -c:v libx264 -analyzeduration 15M -probesize 15M -pix_fmt yuv420p -loglevel 99 C:\\ffmpeg\\bin\\video.mp4";
System.out.println("command = " + command);
try {
Process p = Runtime.getRuntime().exec(command);
final InputStreamReader isr
= new InputStreamReader(p.getErrorStream());
Thread th = new Thread() {
public void run() {
try {
BufferedReader br = new BufferedReader(isr);
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (Exception ex) {
}
}
};
th.start();
} catch (IOException ex) {
System.out.println("Error 1 : " + ex.getMessage());
} catch (Exception ex) {
System.out.println("Error 2 : " + ex.getMessage());
}And here is log for error

ffmpeg send video to ffserver without reencode, CPU usage still very high.How ?
3 septembre 2019, par Wayne ChenI’m using ffmpeg to send H.264 video to ffserver. Command looks like this :
ffmpeg -re -stream_loop -1 -i test.mp4 -c copy http://localhost:8090/feed1.ffmI thought with
-c copyoption, the CPU usage of ffmpeg should be very low, but it actually used 99% of CPU.Please help cutdown the usage of CPU.

[/STREAM]However, when I try to compress it through the following command :
ffmpeg -y -i video.mp4 -vcodec h264 -crf 10 output.mp4the process just finishes super fast without any error but I get an empty file called output.mp4 (its dimension is 0KB).
EDIT : Actually there is something which appears in the console (Even if it is not an error). The following :
The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.I also tried with the following commands (changing codec etc.)
ffmpeg -i video.mp4 output.mp4ffmpeg -y -i video.mp4 -vcodec copy -crf 10 output.mp4ffmpeg -i video.mp4 -vcodec libx264 -crf 10 output.mp4ffmpeg -i video.mp4 -vcodec libx265 -crf 10 output.mp4But I have always the same problem.
