Ganesh Ajjanagadde	520a5d33f0	lavfi/af_aemphasis: remove unnecessary complex number usage complex is not available on all platforms. Furthermore, it is trivial to rewrite complex number expressions to real arithmetic, and in fact sometimes advantageous for performance reasons: by wrapping as a complex, one forces a particular Cartesian representation that is not necessarily optimal for the purpose. Configure dependencies also removed, and aemphasis is now available across all platforms.

Nicolas George	1655788712	lavfi: make request_frame() non-recursive. Instead of calling the input filter request_frame() method, ff_request_frame() now marks the link and returns immediately. buffersink is changed to activate the marked filters until a frame is obtained.	9 years ago
Nicolas George	108b4de552	lavfi: replace link.closed by link.status. The status field can carry any error code instead of just EOF. Also only update it through a wrapper function and provide a timestamp. Update the few filters that used it directly.	9 years ago
Nicolas George	39a09e995d	lavfi: deprecate avfilter_link_set_closed(). Applications are not supposed to mess with links, they should close the sinks. Furthermore, this function does not distinguish what end of the link caused the close and does not have a timestamp.	9 years ago
Nicolas George	b8b7d5ac6c	lavfi: add link.current_pts field.	9 years ago
Nicolas George	d03eab34dd	lavfi: rename link.current_pts to current_pts_us. This field is used for fast comparison between link ages, it is in AV_TIME_BASE units, in other words microseconds, µs =~ us. Renaming it allows a second field in link time base units.	9 years ago
Nicolas George	63f7bee752	lavfi/vf_mpdecimate: remove request_frame(). It is no longer needed since looping is not necessary.	9 years ago
Ganesh Ajjanagadde	ea2f04bffe	lavfi/vf_histogram: replace round by lrint lrint is at least as fast, uses a superior rounding mode, and avoids an implicit cast. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Ganesh Ajjanagadde	7af14b3726	lavfi/vf_colorlevels: replace round by lrint lrint avoids an implicit cast, and is not slower on non-broken libm's. Thus this represents a Pareto improvement. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ganesh Ajjanagadde	cc37b31ad3	lavfi/vf_colorchannelmixer: replace round by lrint lrint is faster here on -ftree-vectorize with GCC. This is likely simply an artifact of GCC's rather terrible auto-vectorizer, since as per the instruction set manuals cvtsd2si and cvttsd2si (or their vector equivalents) have identical cycle timings. Anyway, regardless of above, lrint is superior to round accuracy wise. Safety guaranteed as long int has at least 32 bits. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
