[FFmpeg-devel] [PATCH] libavfilter-soc: extend vf_scale.c to make it support colorspace details setting
Wed Apr 15 22:56:27 CEST 2009
Hi, as in subject,
maybe the patch should be split, also chroma horizontal shifting and
chroma vertical shifting support should be added.
Try it with:
ffplay in.avi -vfilters "scale=0:0:sws_flags\=+print_info:lgb\=3.0:cgb\=3.0:brightness\=-20, format=rgb32"
Note that the format=rgb32 or equivalent is required to make the
destination format of the filter supported by
sws_get/setColorspaceDetails(), or no filtering will be done (the
filter still print a warning in this case).
BTW I get red chroma shifting when using format=argb.
