Comment (by hiccupzhu):

 Sorry, this is my first commit problem.
 This problem reproduce simple, you can download the attachment
 "manga.01.ts".
 Then run:
 {{{
 ffmpeg -i ./manga.01.ts -vcodec copy -bsf:v h264_mp4toannexb
 -hls_list_size 0 -hls_segment_filename "test_%04d.ts" playlist.m3u8
 }}}

 You will be found the file can not be sliced. I follow some sourcecode,
 found ffmpeg can not set the I-frame infomation(AV_PKT_FLAG_KEY).
