• ffmpeg encode image sequence

  1er juillet 2013, par user706167

  I have been using ffmpeg to convert a sequence of jpegs to a video using the following syntax :

  ffmpeg.exe -f image2 -i image_%05d.png -vcodec mpeg4 -b 800k video.mpg

  It doesn't work :

• ffmpeg make image and movie in one command

  22 juin 2012, par knishua

  this is the situation :
  given a thumbnail, i need to overlay it on top of an image.

  so, i need to scale image pass it as parameter to overlay pass that to drawtext.

  I have got so far, adding multiple text + overlay + thumbnail,

  1. ffmpeg -threads 8 -i D:/imagesequence/background.jpg -vf "movie='D\:/imagesequence/dpx/thumbnail.jpg' [watermark]; [in][watermark] overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/3[water];[water] drawtext=fontsize=32:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='shotName':x=(w)/2:y=(h)-50,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Notes \:':x=(w)/5:y=(h)-90,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Frame Range \:':x=(w)/5:y=(h)-130,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Lens \:':x=(w)/5:y=(h)-170,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Undistortion \:':x=(w)/5:y=(h)-210,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Image Sequence \:':x=(w)/5:y=(h)-250,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Date \:':x=(w)/5:y=(h)-290,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Element Name \:':x=(w)/5:y=(h)-330,drawtext=fontfile=/Windows/Fonts/arial.ttf:text='FUTUREWORKS':x=130:y=200:fontsize=54:fontcolor=White[out]" D:\imagesequence\dpx\brn_055.0000.dpx

  2. ffmpeg -threads 8 -i D:\imagesequence\dpx\brn_055.%04d.dpx -vf "drawtext=fontfile=/Windows/Fonts/arial.ttf:text='shotcam':x=(w)/2:y=(h)-35:fontsize=24:fontcolor=Yellow,drawtext=fontfile=/Windows/Fonts/arial.ttf:text='Frame \:':x=(w)-600:y=(h)-35:fontsize=24:fontcolor=Yellow,drawtext=fontfile=/Windows/Fonts/arial.ttf:text='Focal Length \:':x=(w)-600:y=(h)-65:fontsize=24:fontcolor=Yellow" D:\imagesequence\dpx\test2.mov

  3. how do i scale an image and pass it to movie, in 1

  4. how do i make a blackscreen size that of an image say
     'D :\imagesequence\dpx\brn_055.0001.dpx' and pass it to input in 1

  5. is it possible do bother 1 and 2 in one command line ( ffmpeg ....)
     i.e. make an image from first point ( 1 ) and continue with making .mov ( of 1 image + input from point 2 )

  or in other words if it is not possible to do (1 + 2) in one command then is it possible to first execute 1 then execute 2 ( but with output from 1)
  do it
