h264: flag interlaced-coded frames as such when sei_pic_struct indicates otherwise
...
According to the H.264 standard, Annex D, Table D-1, field_pic_flag shall be 0 when sei_pic_struct signals progressive. In the case when this restriction is not fullfilled, its safer to assume the field is actually interlaced.
Not doing so can cause a renderer to assume the frame is progressive and not deinterlace it, even if required.

matroskadec_haali: Only accept a "sane" DefaultDuration for FPS.
...
Alot of files have their DefaultDuration set to an calculated
value which is not directly tied to the FPS, and because Matroska
actually doesn't specify the DefaultDuration to be tied to the FPS,
this is perfectly legal.
So, before assuming the DefaultDuration is the FPS, check if the value
actually makes sense. The most basic check here is that the FPS is
below 125fps, because any more really doesn't make sense.
If the FPS from the header is not set, avformat will probe the FPS
based on the files timestamps, which will give a much better result.
