• Fix mismatched oc_mb_fill_cmapping11 signature.

  31 octobre 2014, par Tim Terriberry

  Fix mismatched oc_mb_fill_cmapping11 signature.
  oc_mb_fill_cmapping11() was defined without the last two parameters
  
   of its fellow mapping functions, meaning it got called with extra
  
   undeclared parameters.
  This could confuse the emscripten JavaScript cross-compiler's asm.js
  
   optimizations, as it's very picky about function signatures.
  Fixes #2068.
  
  Patch by Brion Vibber <brion@pobox.com>.

  • [DH] lib/state.c

• can't find NDK camera and media native API symbols when linking libavdevice.a to libffmpeg.so

  4 septembre 2018, par jianwen

  I’m using NDK tools to build ffmpeg shared lib which will be used in my
  android rtsp project.All needed components are compiled/linked as seperate
  static libs, and at last these libs will be linked as a single shared lib.
  Everything goes well except the last step. error happens when linking
  libavdevice, all symbols in NDK camera and media can not be found, error
  log :

• FFMPEG android compile error

  30 juin 2016, par Sujith Manjavana

  I’m trying to compile ffmpeg for android using ndk. os:ubuntu 13.10. I followed this tutorial. but when i run the build_android.sh it gives me the following errors-

  sujith@Vaio:~$ cd /home/sujith/ndk9d/sources/ffmpeg
  
  sujith@Vaio:~/ndk9d/sources/ffmpeg$ sudo chmod +x build_android.sh
  
  [sudo] password for sujith: 
  
  sujith@Vaio:~/ndk9d/sources/ffmpeg$ ./build_android.sh
  
  /home/sujith/sujith/ndk9d/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-         x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  my build_android.sh is located in ffmpeg source root directory.
  how to fix this ? please help me..
