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 (...) -

FFmpeg can't run in some device Android
30 mars 2016, par tqni’m working in a video processing project and now i’m using ffmpeg library in Android. I’m facing with a strange problem with asus zenphone 4 t00l (or all x86 device, I’ve just test in this x86 phone). When start command in project, app always crash :

Second, I’m afraid that app cannot load version ffmpeg, because in my log, it’s armv7-neon althought it’s x86 (In my test module, it display x86). And according my search result, may be a external library make app to use abi arm (Build.CPU_API="armv7"). So I try remove all library in gradle in module Test and detected a library. But check in aar file of library, it support all x86 and arm. But after remove it, app still crash with same log. And strangely, althogh Test module register as arm but it’still run success (External question : Why add library jp.wasabeef:picasso-transformations make system register as armv7 although it’s x86)
Finally, i think problem is command. But after debug, I use same command for Test module but it still success. Now i’m still stuck with it. Could anyone help me to solve it. Thanks. Here my demo code :
String input = "/storage/emulated/0/Videa/Video/VIDEO_20160122_160020.mp4";
String output = "/storage/emulated/0/Videa/Audio/AUDIO_20160330_142501.wav";
String[] command = {
"-y",
"-i",
input,
"-vn",
"-f",
"wav",
output
};
FFmpeg ffmpeg = FFmpeg.getInstance(getApplicationContext());
try {
ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
@Override
public void onSuccess(String message) {
super.onSuccess(message);
System.out.println("Success " + message);
}
@Override
public void onFailure(String message) {
super.onFailure(message);
System.out.println("Failure " + message);
}
});
} catch (Exception e) {
e.printStackTrace();
}And here is Failed command :
ArrayList<string> cmd = new ArrayList<string>();
cmd.add("-y");
cmd.add("-i");
cmd.add(input);
cmd.add("-vn");
cmd.add("-f");
cmd.add("wav");
cmd.add(output);
String[] result = new String[cmd.size()];
return cmd.toArray(result);
