Hi,
Currently, MPEG2 postprocessing 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 in the bottom
half of the image. The attached patch fixes this issue.
The filters should be also adjusted to process interlaced content
properly (maybe later), but at least the worst artifacting is gone and
resulting video is watchable.
Regards,
