[FFmpeg-user] ffmpeg convert a blue-ray file is so slowly

[lym]

Hi


    I'm using ffmpeg convert video. but a blue-ray film is very slowly. I doubt the question is the file has multiple channels.


my ffprobe cmd result is :

        }
    }
}


and my ffmpeg command is :
/home/admin/mts/jobagent/tools/ffmpeg -y -vsync 1 -async 1 -ss 7008 -t 12.0 -i "/home/admin/tomcat/webapps/ROOT/ttt.mkv" -map 0:0 -map 0:1  -codec:v libx264 -codec:a libfaac  -b:v 200k -s 590*320 -f ssegment -segment_list_type m3u8 -segment_list "EAATEA-.m3u8" -segment_list_flags +live -segment_time 4  "fname=00000584_%08d.ts"


The command execute very slowly , who had handle the thing.
Thank you very much!
