Subject: [PATCH 01/14] vf_bwdif: Add capability to deinterlace NV12
|
|
|
|
As bwdif takes no account of horizontally adjacent pixels the same
|
|
code can be used on planes that have multiple components as is used
|
|
on single component planes. Update the filtering code to cope with
|
|
multi-component planes and add NV12 to the list of supported formats.
