Development in Android local video player

In the local video section of the Android local video player development, we were able to search for local video and display pictures, titles, and lengths of each video, and of course, if you needed to add other lengths and widths of video, for example, you could use the video class method, and now that we get the videos, So next is decoding the video, decoding the video I'm using FFmpeg, so this is the FFmpeg library you can use to compile your phone with NDK.

This script I was enabled neon, so can only run on neon mobile phones, if you want to run to a non-neon mobile phone, you need to remove the neon features.

Then execute this script, and it will generate libffmpeg-neon.so
