It seems that ffmpegcolorspace insists on rounding up widths and heights at
times, which breaks other elements.

gst-launch filesrc blocksize=1000000 location=aay.jpg ! jpegdec !
ffmpegcolorspace ! video/x-raw-rgb ! ffmpegcolorspace ! jpegenc ! filesink
location=out.jpg

This pipeline results in out.jpg having bad colors. The Y plane is correct (no
rounding there, no wonder it is good!), but the U and V planes appear to have
bad strides.

Similar problems happen in other cases too, but I haven't been able to come up
with a simple case to reproduce those, yet.

Find attached the input and output pictures mentioned above.
