[MPlayer-dev-eng] [PATCH] libmpeg2 - fix quantizer export for interlaced content

Hi,

Currently, postprocessing of the images decoded by libmpeg2 corrupts the
image when the content is interlaced. The reason is that our patched
libmpeg2 stores the qscales _twice_ into the top half of the
quant_store, while the bottom one contains only garbage, which results
in ugly artifacting (at best) in the bottom half of the image. The
attached patch fixes this issue by also storing the qp's interlaced,
and also sets the interlaced flag so it can be used by the filters.

Regards,
