    7 novembre 2011, par Satheesh

    I have try to implement the ffmpeg decoding library in my android project.Dowload FFmpeg.I got the ffmpeg library from the bambuser client version and unpack that into the project jni folder.Then i run the extract command(./extract.sh) in cygwin compiler tool(its becoz am using windows os) after that am trying to build ffmpeg library using the command ./build.sh

  • FFMPEG with Neon Optimization

    11 juin 2015, par madadi

    I am decoding an h.264 video file on android using ffmpeg. The performace is very low. I would like to enable neon optimzation in ffmpeg to improve the performace. Inspite of adding the neon related commands in the config file, I don’t see performance gain. Can someone tell me if I am going wrong anywhere ? My config file is as given below.

        function build_one_r6
