Note, the design is still flawed, dont expect this to be frame
accurate. float/double first needs to be removed and frames
itself trimmed instead of drop vs nodrop

Options are freed from the generic code now, there is no need to call
av_opt_free() from the filter.

From various tests, there is no evidence that the filter is faster than

This avoids invalid free when the stream id doesn't match the packet
stream index.

Ticket #2501

Both don't change anything in the context between frames.

Fix checkheaders when vid.stab is not available.

The frame must be writable if the show option is set, otherwise pass the

vidstabdetect and vidstabtransform common functions for interfacing
vid.stab are in libavfilter/vidstabutils.c
