bmovl uses the images stride incorrectly

[floemker]

The bmovl filter allocates memory for a local image. The size of that
memory area is always width * height. But at different locations in the
filter that image is accessed with the incoming images stride as the
width. The stride must be used only when accessing the incoming image.
Otherwise the copied image is distorted.

The attached patch fixes that for me.

Patch to fix incorrect accessing of the local image in the bmovl filter.

I think your changes in regard to chroma are slightly wrong.

Otherwise the patch seems good.

I plan to apply it soon, with some small changes in the chroma parts.

Thanks for reporting and contributing.

Should be fixed in MPlayer SVN r37901.

Please confirm the fix or re-open this ticket.

After fixing an unrelated crashing bug in bmovl (ticket #2308)
I can confirm that this works now fine.

Thanks.
