As this works only with very few formats (MJPEG and raw mostly) I
don't think this has a chance of getting into CVS, but
the seek command now supports fractional values, so you should now be able to
get the same result (for e.g. 25 fps video) with:
, seek -0.04
in your input.conf file (you can even add pausing before seek, so you
have frame stepping).
Of course you will have to use different values for different
framerates, so the functionality is not the same, but better than
nothing IMHO.
