Nicolas Frattaroli	6a50a8f340	snowenc: fix use of deprecated API Replace avcodec_get_chroma_sub_sample with the recommended av_pix_fmt_get_chroma_sub_sample, which fixes a compilation warning. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago

Derek Buitenhuis	e8c5d5f429	snow: Move scenechange_threshold to a private option Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago

Ganesh Ajjanagadde	c5b3c4c741	lavc/snowenc: replace rint by lrint avoids float to int cast. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Ganesh Ajjanagadde	4870d8518a	avcodec/snowenc: use log2 instead of log() / log(2...) This is likely more precise and conveys the intent better. The expression has also been accordingly simplified.

Ronald S. Bultje	2fb593dcb9	Put remaining pieces of CODEC_FLAG_EMU_EDGE under FF_API_EMU_EDGE. The amv one probably looks suspicious, but since it's an intra-only codec, I couldn't possibly imagine what it would use the edge for, and the vsynth fate result doesn't change, so it's probably OK.	9 years ago

Michael Niedermayer	58201c6e9e	avcodec/snowenc: correct fullpel search pattern No real difference in quality, its a bit slower for the same dia_size as more vectors are searched for the same dia_size Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
