Rudolf Polzer 5589412b3c vf_dlopen framestep: step width of 0
This is now defined to mean to never output any frame again (except for
the first).

Rudolf Polzer 34e542591b vf_dlopen framestep filter: add a parameter for the phase
also, default to 0-indexed frame counts (so by default, the 1st frame is
output). Old behaviour can be done by -vf dlopen=./framestep.so:42:41.

Rudolf Polzer 2958ae39ca vf_dlopen examples: slightly simply the framestep filter
We don't need config() ;)

Rudolf Polzer c22482e08d TOOLS: fix first frame pts for dlopen/telecine.so
When the first frame of a telecine pattern did not generate an output
frame (because it is a 0 or a 1), this could lead to the first two
output frames getting equal pts values.

When the first frame of a telecine pattern generates exactly one output
frame (i.e. when the telecine pattern starts with 2 or 3), then the
output was correct before this comment, and still is unchanged.

When the first frame of a telecine pattern generates more than one
output frame (i.e. when it starts with 4 to 9), then output pts are
still broken. This is not really solvable without knowing the frame
duration, or delaying output by one frame.

Rudolf Polzer 6371787b89 vf_dlopen: vf_rectangle filter moved to dlopen (unix only)
It is unix only, because vf_dlopen filters have no way to receive input (yet)

Rudolf Polzer 9343c1d3ab vf_dlopen: improve performance for 1-frame-for-1-frame filters
This is done by requesting a buffer from the next filter in the chain, instead
of always allocating our own. This allows the next filter to e.g. ensure its
own preferred memory layout.

Rudolf Polzer 2adc81f0a2 vf_dlopen: add a generic filter to load external filters
Usage: -vf dlopen=filename.so:args...

Examples of such filters are provided in TOOLS/vf_dlopen/
