ffmpeg下載地址：http://ffmpeg.org/releases/
1.首先需要安裝解碼器集合（包含安裝ffmpeg用到的所有解碼器）下載地址：
連結: https://pan.baidu.com/s/1gxtRLmx20jhvBDHn3qBffA 提取碼: pwja
因為我的專案中使用x264的解碼方式，所有我只安裝該解碼器。
程式碼地址：https://www.cnblogs.com/lemon2019/p/14106794.html
tar -xvf x264-master.tar.bz2
cd /usr/local/src/ffmpeg/x264-master/
./configure --prefix=/usr --enable-shared make make install
2.ffmpeg安裝
tar -vxf ffmpeg-4.3.tar.bz2安裝完成後執行: /usr/local/ffmpeg2/bin/./ffmpeg時出現
./configure --prefix=/usr/local/ffmpeg2 --enable-libx264 --enable-gpl
make
make install
errorwhileloadingsharedlibraries: libavdevice.so.53:cannotopensharedobjectfile:Nosuchfileordirector
錯誤，是因為共享庫檔案安裝到了/usr/local/ffmpeg2/lib目錄下, 那麼把新共享庫目錄加入到共享庫配置檔案/etc/ld.so.conf中, 如下:
# cat /etc/ld.so.conf include ld.so.conf.d/*.conf # echo "/usr/local/ffmpeg2/lib" >> /etc/ld.so.conf # ldconfig
再次執行 /usr/local/ffmpeg2/bin/./ffmpeg
如果出現如下版本資訊則安裝成功：
[root@xa-server150 ffmpeg]# /usr/local/ffmpeg2/bin/./ffmpeg ffmpeg version 4.3 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-36) configuration:--prefix=/usr/local/ffmpeg2 --enable-libx264 --enable-gpl libavutil 56. 51.100 / 56. 51.100 libavcodec 58. 91.100 / 58. 91.100 libavformat 58. 45.100 / 58. 45.100 libavdevice 58. 10.100 / 58. 10.100 libavfilter 7. 85.100 / 7. 85.100 libswscale 5. 7.100 / 5. 7.100 libswresample 3. 7.100 / 3. 7.100 libpostproc 55. 7.100 / 55. 7.100 Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

3.驗證視訊格式轉碼：
