[QUOTE="mrfg, post: 1105407, member: 111078"] hello again, in code line : #154, #155 [code]ffmpegArgs = string.Format("yadif=0:-1:0,scale=600:337,setsar=1:1,tile={0}x{1}", 1, 1); ExtractorArgs = string.Format("-loglevel quiet -ss {0} -i \"{1}\" -y -ss {2} -vf {3} -vframes 1 -vsync 0 -an \"{4}_{5}.jpg\"", TimeOffset, aVideoPath, TimeToSeek, ffmpegArgs, strFilenamewithoutExtensionTemp, i)[/code] so, for my test it's like : [code]ffmpeg.exe -loglevel quiet -ss 0 -i test_video.ts -y -ss 00:23:00.000 -vf yadif=0:-1:0,scale=600:337,setsar=1:1,tile=1x1 -vframes 1 -vsync 0 -an out.jpg[/code] --- and this took ~ 2-3 minuts. which is not good. no meaning extracting 1 image per every minute when the extracting process takes more then 1 minute. or did I do something wrong ... ?[DOUBLEPOST=1413780367][/DOUBLEPOST]I've got answer, if need somebody fast seek untill it reaches 00:22:00, and then slow seek (frame by frame) 00:01:00 => 00:23:00 [code]ffmpeg.exe -loglevel quiet -ss 00:22:00.000 -i test_video.ts -y -ss 00:01:00.000 -vf yadif=0:-1:0,scale=600:337,setsar=1:1,tile=1x1 -vframes 1 -vsync 0 -an out.jpg [/code] details : [url]https://trac.ffmpeg.org/wiki/Seeking%20with%20FFmpeg[/url] [/QUOTE]
