317b2b7e92 lavfi: remove av_buffersrc_buffer. 
It is no longer used anywhere.

Furthermore, the header it was declared in was not installed,
so it can not be considered part of the public API.

av_buffersrc_buffer().

126ba1626e lavfi/drawtext: give a new alias "timecode_rate" to the the r/rate option 
The option is related to the timecode, the new name clearly specifies the
context. Also it allows to list the option close to the other timecode
options.

837d034787 lavfi/tinterlace: make video as interlaced in mode 6 
This is useful for marking progressive video processed by the filter as
interlaced, avoiding the interlaced flag to switch back and forth at each
frame.

820c023142 lavfi/tinterlace: add tinterlace mode 6 
This new mode is useful for generating frames for interlaced video
displays. Typically interlaced video displays have no form of field
synchronisation. This new mode guarantees correct field order without
any requirement for field synchronisation.

75d5624cb2 avfilter: filter_samples: read pts before filtering. 
The call to the next filter_sample will likely unref the
current buffer, so it is not possible to read it afterwards.

6b55aab01a lavfi: create buffer reference in filters which need to access the ref later 
Also add internal function ff_null_start_frame_keep_ref().

Fix crash when a following filter (e.g. settb) will unref the reference
passed by start_frame(), and then the reference is accessed in
end_frame() through inlink->cur_buf.

fd2cd64fc9 avfiltergraph: fix format selection. 
The old code had two bugs:

For audio filters, the format was not set.

For video filters, if several links reference the same format list,
the same format must be selected in the end. This is done by
setting formats->format_count to 1: the other links sharing
the reference will therefore have only one choice.
If the heuristic does not pick the first format, the selected format
must also be moved to the first position.
