Add AVFilterPicRef.pos field and make libavfilter propagate streambyte position information, as stored in the pkt.pos, through thefilterchain.
Note that the pos field is added non at the end of theAVFilterPicRef struct, thus breaking ABI compatibility, which is...
avfilter: make avfilter_default_free_video_buffer() static
This function is not referenced outside this file and has noprototype. Feel free to flame if this is wrong.

Make avfilter_default_start_frame() correctly pass the aspect ratioinformation to the next filter.

Make avfilter_default_start_frame() request a buffer with the samesize of the output link of the destination filter, rather than of thesize of the input link.In particular this fixes a crash in the rotate filter.

Add a slice_dir parameter to avfilter_draw_slice().
Avoid the need to implement slice direction detection code, thusreducing code duplication.

Make avfilter_get_video_buffer() recursive.
When called on a link with a filter whose destination pad has not aget_video_buffer callback defined, it will callavfilter_get_video_buffer() on the first output link of thedestination filer, rather than use avfilter_default_get_buffer(), so...

Rework link property configuration system.This can now handle filters which are added to graphs out of order,including auto-inserted scale filters. As an added bonus, it cannow detect circular filter chains which wouldn't work anyway.

Track the permissions that have been given out to each picture.This should make it easier to know what can be done to a buffer onceit's been passed to your filter without falling back to copying it "justto be safe".
