Ganesh Ajjanagadde	cd8a0a9a9a	swscale/swscale: add av_warn_unused_result to sws_init_context This should not trigger any warnings; but adds robustness. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Pedro Arthur	5bd62a1b3c	swscale: fix ticket #4881 When scaling only a slice of a frame the output was written always in the first lines leaving the rest of the frame black.	9 years ago
Ganesh Ajjanagadde	3b2000c2bf	doc/scaler, swscale/options: use proper capitalization Proper names should be capitalized in all user facing API as far as possible. The option names themselves have not been changed since: 1. We consistently keep option names in lower case. 2. Changing them would break existing scripts. The converse is also true: improper names should not be capitalized generally.

Ganesh Ajjanagadde	26e8895b73	all: add _DEFAULT_SOURCE locally wherever needed Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE. The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros. This solution is on the lines of the one in commit `af1818276e`.

Ganesh Ajjanagadde	80d23d9d32	swscale/swscale: silence unused function warning gamma_convert is only used with the old code. Thus, it is placed under a header guard. This patch silences a -Wunused-function observed on GCC 5.2. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Michael Niedermayer	d730dd8c53	swscale: Forward colorspace updates to the 2nd cascaded context in case of alphablend The first just does the blending and wouldnt do anything with the colorspace values Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	8e05f9217a	swscale/utils: Split scaling if possible and yuv->yuv with different matrixes is requested This uses a RGB intermediate, a more optimal solution would be to perform the rematrixing directly in subsampled YUV, this is quite a bit more complicated though Fixes Ticket4805 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
