[FFMPEG] Known problem with "Frame size must be a multiple of 2"

[yamyam]

Hello everyone!

I am using a software, that generates thumbnails from video files.
So far I've used mplayer to generate thos thumbs.
Since ffmpeg can create much cleaner and better thumbs, I changed the appropriate command line in the code and it runs everything perfectly ...

ffmpeg -ss [timeCode] -i [inFile] -vcodec mjpeg -vframes 1 -an -f rawvideo -s [scaleWidth]x[scaleHeight] [outDir]/output.jpg 1> /dev/null 2> [debugFile]

... except if the output format of the thumbs is ODD!
(So for example, 640x481 pixels)

This follows from the error log:

Frame size must be a multiple of 2

See here:
http://www.google.de/#hl=de&source=hp&q=ffmpeg+%22Frame+size+must+be+a+multiple+of+2&b...f+2&fp=1&cad=b

I've read through but I found nothing useful
There must also be a possibility to get FFMpeg to work as perfectly as mplayer does if the thumbsize/videosize is odd.

Here, i would need your help, hints or solutions!


Thank you very much!
