2013-03-28lavfi/gradfun: fix rounding in MMX code.Clément Bœsch
Current code divides before increasing precision. Also reduce upper bound for strength from 255 to 64. This will prevent an overflow in the SSSE3 and MMX filter_line code: delta is expressed as an u16 being shifted by 2 to the left. If it overflows, having a strength not above 64 will make sure that m is set to 0 (making the m*m*delta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>

2013-03-19avplay: remove the -debug option.Anton Khirnov

2013-03-18print_options: do not generate docs for options without enc or dec flagsAnton Khirnov
Those are not usable from the avtools, so mentioning them in the manpages just confuses the reader.

2013-01-09oggenc: add a page_duration option and deprecate the pagesize optionJustin Ruggles
This uses page duration instead of byte size to determine when to buffer the page. Also, it tries to avoid continued pages by buffering the current page if there are already packets in the page and adding the next packet would require it to be continued on a new page. This can improve seeking performance. The default page duration is 1 second, which is much saner than filling all page segments by default.

2013-01-07doc: Extend commit message sectionDerek Buitenhuis
If a bug exists on the tracker, its ID should always be included in fix messages. Also, any relevant bug fixes should be CC'd to libav-stable, so we can actually track what needs to be backported, instead of just randomly combing the git history and old CVEs.
