• FFMPEG JNI wrapper causes Android app exit

  5 décembre 2013, par user3043703

  I'm writing a JNI wrapper to use FFMPEG as a library in my Android project. I'm mainly using as references the halfninja project (and some forks) and this useful guide. I'm making a lot of personalizations but I got a working version with some additional codecs, the only problem is that, after FFMPEG ends, it causes my application to quit with no errors and I'd like to avoid this (for example to invoke FFMPEG again). Looking at the halfninja wrapper, the line of code exit(ret) ; from the cmdutils.c file is commented in the function void exit_program(int ret) but if I do the same with the latest (2.1.1) version of FFMPEG it causes me a signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 6f632494 error. My code looks like this :

  void exit_program(int ret)
  
  {
  
     if (program_exit)
  
        program_exit(ret);
  
  
  
     //exit(ret);
  
    //if I uncomment this the app automatically exits without errors
  
  }

  I see that both my references are a little old, also refering to a very old release of FFMPEG and it seems that meanwhile the source code changed a lot. I invoke FFMPEG through the JNI wrapper inserted in a new thread in the application code.

  All I'd like to know is : there's a way to avoid the automatic exit of my application after the end of FFMPEG thread ?

• Revision d8b4c79270 : Decouple macroblockd_plane buffer usage Make the macroblockd_plane contain dyna

  31 octobre 2013, par Jingning Han

  Changed Paths :
   Modify /vp9/common/vp9_blockd.h

  
   Modify /vp9/decoder/vp9_decodframe.c

  
   Modify /vp9/decoder/vp9_onyxd_if.c

  
   Modify /vp9/decoder/vp9_onyxd_int.h

  
   Modify /vp9/encoder/vp9_onyx_if.c

  
   Modify /vp9/encoder/vp9_onyx_int.h

  
  
  Decouple macroblockd_plane buffer usage

  Make the macroblockd_plane contain dynamic buffer pointers instead
  static pointers to the memory space allocated therein. The decoder
  uses the buffer allocated in pbi, while encoder will use a dual
  buffer approach for rate-distortion optimization search.
