切分mp4视频:

ffmpeg -y \
-i "/tmp/mda-mh4d5tn0e89vvqrm.mp4" \
-hls_time "10" \
-hls_key_info_file "/tmp/enc.keyinfo" \
-hls_playlist_type "vod" \
-hls_list_size "0" \
-hls_segment_filename "/tmp/ffmpeg_%d.ts" \
"/tmp/ffmpeg_playlist.m3u8"

hls_time：指定生成 ts 视频切片的每片时间长度
hls_key_info_file：enc.keyinfo文件的位置
hls_list_size: 索引播放列表的最大列数默认5，0 为不限制
hls_segment_filename：生成ts和m3u8文件的路径及文件名
