• FFmpeg cross compile for Android fails with on C compiler test for x86_64

  5 novembre 2018, par nLL

  I am trying to cross compile FFmpeg for Android with NDK r16b
  I have manged to compile without any issues for all platforms but x86_64.

  Here is my compile script

          #!/bin/bash
  
  
  
  
  
  
  
      function build_one

      collect2: error: ld returned 1 exit status
  
      C compiler test failed.

  So, error is "unsupported ELF file type 2" which means 64 bit. But, I am trying to build 64 bit library anyway.

  I do not understand what is the issue here. Can anyone give me some direction ?

• ffmpeg watermark from java Runtime.exec cannot find output

  20 avril 2021, par Rohi

  I'm having a problem in sending a ffmpeg command to add a watermark to my video from Java using Runtime.exec().
The strange thing is that the same command is working perfectly from terminal.... 
Any idea what the issue could be ?
this is the command

  



  ffmpeg -i /home/mydir/inputvideo.mp4 -vf "movie=/home/mydir/watermarklogo.png [wm]; [in][wm] overlay=10:10 [out]" /home/mydir/outputvideo.mp4


  



  and this is the Java code (same as above, just wrapped in the exec code, and escaped characters

  



  Runtime rt = Runtime.getRuntime();
        Process proc = rt.exec("ffmpeg -i /home/mydir/inputvideo.mp4 -vf \"movie=/home/mydir/watermarklogo.png [wm]; [in][wm] overlay=10:10 [out]\" /home/mydir/outputvideo.mp4");
        InputStream stderr = proc.getErrorStream();
        InputStreamReader isr = new InputStreamReader(stderr);
        BufferedReader br = new BufferedReader(isr);
        String line = null;
        while ( (line = br.readLine()) != null)
            System.out.println(line);
        int exitVal = proc.waitFor();
        System.out.println("Process exitValue: " + exitVal);


  



  exit code is always 1 when running this.... this is the full output
