This article describes how to use FFMPEG in PHP to obtain video thumbnails and video durations. For more information, see The Code is as follows: // Obtain the thumbnail of the video fileFunction getVideoCover ($ file, $ time, $ name ){If (empty ($ time) $ time = '1'; // the first frame of the first second is interce

This document records the FFmpeg-based video decoder on another Android platform. Unlike the decoder documented in the previous article, the decoder documented in this article no longer uses class libraries such as libavcodec.so, libavformat.so, and only uses a class library--libffmpeg.so. The source code for the video decoder C language comes from the simplest
