Description
One of my local digital channels broadcasts content with bottom field first. When using yadif (2x), the fields are displayed in the wrong order. The other 2x deinterlacers look better, and when I play a recording using MPlayer with -vf yadif=1, it looks fine. If I tell MPlayer that the file is top-field-first, its output is similar to mythtv.

(In [19983]) Fix YADIF deinterlacer so it correctly handles bottom field first streams. Fixes #5257.
N.B. There is duplication of deinterlacing code between NuppelVideoPlayer?, Greedyhdeint and Yadif. Ideally we should rely on NuppelVideoPlayer? and simply tell the deinterlacers what to deinterlace. Additionally users cannot currently override the field order for interlaced streams when using these deinterlacers.
Can you upload a short clip from that channel that displays the issue well (i.e. some scrolling text or similar).
I can't find any bottom field first streams to test this with.
