首先可以通过ffprobe查看视频信息 （可选）
执行： ./ffprobe Beach-Ball.mp4 iZm5ecuy8n2epwa3gno33xZ:/opt/yizhichao/ffmpeg-4.0.2-64bit-static # ./ffprobe Beach-Ball.mp4 ffprobe version 4.0.2-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2007-2018 the FFmpeg developers built with gcc 6.3.0 (Debian 6.3.0-18+deb9u1) 20170516 configuration: --enable-gpl --enable-version3 --enable-static --disable-debug --disable-ffplay --disable-indev=sndio --disable-outdev=sndio --cc=gcc-6 --enable-fontconfig --enable-frei0r --enable-gnutls --enable-gray --enable-libaom --enable-libfribidi --enable-libass --enable-libvmaf --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-librubberband --enable-libsoxr --enable-libspeex --enable-libvorbis --enable-libopus --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzimg libavutil 56. 14.100 / 56. 14.100 libavcodec 58. 18.100 / 58. 18.100 libavformat 58. 12.100 / 58. 12.100 libavdevice 58. 3.100 / 58. 3.100 libavfilter 7. 16.100 / 7. 16.100 libswscale 5. 1.100 / 5. 1.100 libswresample 3. 1.100 / 3. 1.100 libpostproc 55. 1.100 / 55. 1.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Beach-Ball.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 creation_time : 2015-08-24T11:27:32.000000Z encoder : Lavf55.33.100 Duration: 00:00:15.70, start: 0.000000, bitrate: 2526 kb/s Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 2525 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default) Metadata: creation_time : 2015-08-24T11:27:32.000000Z handler_name : VideoHandler iZm5ecuy8n2epwa3gno33xZ:/opt/yizhichao/ffmpeg-4.0.2-64bit-static #
再用ffmpeg把Beach-Ball.mp4文件转换为beachball.ts文件：

最后用ffmpeg把beachball.ts文件切片并生成playlist.m3u8文件，5秒一个切片：
