Mark Visser 0defc77e9d added start_number parameter to drawtext to permit an offset to n/frame_num var 2013-06-14 17:05:19 -04:00
Jean Delvare cef42ded8d drawbox: Respect thickness parameter 
The drawbox video filter is drawing lines one pixel thinner than
requested. The default thickness is 4 pixel but in fact the lines
drawn by default are only 3 pixel wide.

Change the comparisons in the code to fix this off-by-one bug. Also
change the default thickness from 4 to 3 to minimize the unexpected
changes from the user's perspective.

As I was already touching these lines, I also removed the "maximum" in
the thickness parameter description, as I don't think it was adding
any value and I even found it confusing.

Stefano Sabatini 0400176772 lavfi/mp: remove mp=tinterlace wrapper 
From various tests, there is no evidence that the filter is faster than
the native tinterlace, and it has several more limitations and a few
bugs.
