* TOOLS: fix first frame pts for dlopen/telecine.soGravatar Rudolf Polzer2012-09-28
| | | | | | | | | | | | | | | 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.
* vf_dlopen: vf_rectangle filter moved to dlopen (unix only)Gravatar Rudolf Polzer2012-09-18
| | | | It is unix only, because vf_dlopen filters have no way to receive input (yet)
* vf_dlopen: improve performance for 1-frame-for-1-frame filtersGravatar Rudolf Polzer2012-09-18
| | | | | | 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.
* vf_dlopen: add a generic filter to load external filtersGravatar Rudolf Polzer2012-08-23
Usage: -vf dlopen=filename.so:args... Examples of such filters are provided in TOOLS/vf_dlopen/
