我可以使用以下m3u8命令从.ts视频文件生成mp4和段（ffmpeg）文件列表
ffmpeg -i Bee_Free.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment -segment_list free.m3u8 -segment_time 10 free%03d.ts
我使用相同的命令从m3u8和ts文件生成.wmv和.avi个文件
.avi文件的命令
ffmpeg -i PalivalaBadraVatakam.avi -codec copy -vbsf h264_mp4toannexb -map 0 -f segment -segment_list palivaala.m3u8 -segment_time 10 palivaala%03d.ts

带有TS文件的HLS仅支持h.264视频编解码器和aac或mp3音频。因此-codec副本将无法正常工作。只需删除它，ffmpeg应自动选择libx264。
