You're using a capsfilter to force a particular pixel format, size, and

You use ffmpegcolorspace (which can convert to the required pixel
format), but you don't have anything to convert to the size and
framerate you're asking for.

One specific problem you're likely to run into is that many files have
non-square pixels, but ximagesink requires square pixels. You can use
the 'videoscale' element to resize appropriately.

You can also try using videorate to change video framerate.

There may be other problems with your code, I didn't read it closely or
try it myself.
