Hi Guys,
The FFmpeg hls module can make m3u8 and ts, but it dosen't delete the
old ts segment file.
If always run this module, the disk will full, so this patch can fix
the problem.
When update the segment list m3u8 file, it will delete the ts segment
out range from the list file.
before use this patch:
[root@localhost ffmpeg]# ls *.ts *.m3u8
a0.ts a10.ts a11.ts a12.ts a13.ts a14.ts a15.ts a16.ts a17.ts
a18.ts a19.ts a1.ts a20.ts a2.ts a3.ts a4.ts a5.ts a6.ts a7.ts
a8.ts a9.ts a.m3u8
[root@localhost ffmpeg]# cat a.m3u8
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:11
#EXT-X-MEDIA-SEQUENCE:16
#EXTINF:10.427075,
a16.ts
#EXTINF:10.427075,

#EXTINF:10.427075,
a19.ts
#EXTINF:3.670330,
a20.ts
#EXT-X-ENDLIST
[root@localhost ffmpeg]#
after use this patch:
[root@localhost ffmpeg]# ls *.ts *.m3u8
a10.ts a11.ts a12.ts a13.ts a9.ts a.m3u8
[root@localhost ffmpeg]# cat a.m3u8
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:11
#EXT-X-MEDIA-SEQUENCE:9
#EXTINF:10.427075,
a9.ts
#EXTINF:10.427075,
a10.ts
#EXTINF:10.427075,
a11.ts
#EXTINF:10.427075,
a12.ts
#EXTINF:2.335665,
a13.ts
#EXT-X-ENDLIST
[root@localhost ffmpeg]#
