Tv-Server plugin Extract Images (1 Viewer)

[mrfg]

Hello,
Is it possible to develop tv-server plugin which does : extract images (1 image per every minute) while capturing or recording the stream?

if yes please give a tip or any document to develop this, thank you.

It is possible. Check the code of the thumbnail processing.
Read this wiki page: http://wiki.team-mediaportal.com/MediaPortal1_Development

hello, thank you for reply.
I just checked code of thumbnail processing. (not every details..) it uses ffmpeg.
so if recording file length is 1 hour and I need 59th minute's thumbnail/frame image. it takes time.... right?
can I do it more faster? or ... ?

No. You can jump in the file (using -ss). Check the doc of the ffmpeg.

Or check the code here: https://github.com/MediaPortal/Medi...s/VideoThumbCreator/VideoThumbCreator.cs#L123

hello again,

in code line : #154, #155

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)

so, for my test it's like :

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

--- 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

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
