  • How I can use Runtime.getRuntime.exec with ffmpeg library in Android ?

    24 février 2015, par beni

    I’m trying to establish the correct rotation in my recorded video because in some devices the setOrientationHint method doesn’ work becuase in some video players may choose to ignore the compostion matrix in a video during playback, Android Documentation.

    So, I’ve decided to use the ffmpeg library. I’m develop a test for the app. In Ubuntu, I download this library and execute the configure and make to obtain the ffmpeg executable, I copy this executable to the DCIM folder in the sdcard, the same for a video what I’ve recorded for my camera recorder app. So, in the DCIM folder, I have the ffmpeg executable and a video.

    I created a test project and in the onCreate method, I’ve include :

    try {
    

    
Process p= Runtime.getRuntime().exec("chmod 777 /mnt/sdcard/beni/ffmpeg");
    
p.waitFor();
    

    
p = Runtime.getRuntime().exec("/mnt/sdcard/beni/ffmpeg -i /mnt/sdcard/beni/f.mp4 -vf \"transpose=1\" -r 24 -sameq /mnt/sdcard/beni/f2.mp4");
    
p.waitFor();
    

    
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));  
    
String line = null;  
    
while ((line = in.readLine()) != null) {  
    
    System.out.println(line);  
    
}  
    

    

    

    

    
} catch (IOException e) {
    
    e.printStackTrace();
    
} catch (InterruptedException e) {
    
e.printStackTrace();
    
}

    but I have the following warning :

  • Live stream RTMP/RTSP player without using webview (WOWZA server) on Android

    2 septembre 2016, par SweetWisher ツ

    I am developing an Android application in which I want to publish as well as stream a video...

    What I want is :

    1. My app records a video and that video is sent to the server

    2. The recorded video will be streamed live to another Android device at the same time..

    I have completed the first task using javac and ffmpeg. I am stuck in the second task. I have searched a lot to stream the video from the server, but I didn’t succeed. I don’t want to use WebView and play the video in it. I want an RTMP player. This task has been completed in iOS... I want the same for Android. What is some link to fulfill my task ?

    P.S. :

    I am using wowza server and RTMP stream. I would like to stream RTMP video (.flv)... If no solution is available, I would like to switch to RTSP and for that also, need a working link to follow..

    Now I have switched to RTSP player [with wowza server] as I have not found an RTMP player without webview. How do I fix this issue ?
