vf_frei0r: prevent a segfault when filter parameters are not set
Merged-by: Michael Niedermayer <michaelni@gmx.at>
MicroDVD files are normally frame-based (i.e. there are no absolute
timestamps), but can have an optional frame rate header. If this
header is missing, the timestamps depend on the frame rate of the
video they were created for.
The demuxer will use a fallback frame rate if it's missing from the
header. Currently, applications using libavformat can't know whether
the time base is based on the fallback value, or if a frame rate
header was present.
This commit introduces a subfps AVOption for MicroDVD, and the
demuxer sets it if and only if a frame rate header was present.

The BOM is already skipped in the probe function, but not the header
read function. This could cause the header to be misparsed, such as
not interpreting the FPS line.
When using the wrap option the EXT-X-MEDIA-SEQUENCE header of the playlist file was reset instead of being incremented.
It is now incremented by one for every media URI removed from the playlist file as the standard states.

With cli usage the decoder might have not set the colorspace during
encoder init, manual colorspace override might be needed in such
cases.
