Thanks that was it
And if I Would like to have each image shown during 15 seconds (I have 15
pictures and whants the total time being 225 sec), How should I specified the
-framerate and -r ? I tried
ffmpeg -y -f image2 -framerate 1/5 -i %%02d.JPG -i SligoAir_WhiteBlanket.mp3
-vsync vfr -r 15 -pix_fmt yuv420p output.mkv
But that it's too short a time for each picture
"-framerate 1/5" specifies the framerate at which you read the pictures,
1/5 means 5 seconds.
"-r" is the output framerate. If you omit this option, then the default
25fps is used. Some players have problems with small framerates.
If you want crossfadings between the pictures, have a look at chapter
2.3 in my book:
