the particulars is i save a rtsp stream to ts file by ffmpeg per 10 second , it may last for a long time(more than 26.5hour), when it done, it will save a m3u8 file, after that, i use ffplay to play then m3u8 file, if i want to seek to 26.7hour , the play must be stoped. -----PTS (sec) = 8589934592 / 90 000 Hz = 95443,7 seconds (26,5 hours)
