* vf_scale: conditionally override chroma positionChristophe Gisquet2015-09-23
| | | | | | | | | | For yuv420p, the chroma position is unilaterally overriden, even if ffmpeg's command-line explicitly set it. To fix this, override only if the value is the default one. Regression since 1515bfb3. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* lavfi/scale: Pass src_range and dst_range to libswscale.Carl Eugen Hoyos2015-09-01

| | | | | | | | | | | | | | This reverts commit 63be97ec403023fb664798432acedaf6e6922527. All those calls were unchecked on purpose, as explained in the comments in the code.

| * vf_scale: use the pixfmt descriptor APIAnton Khirnov2014-05-26
| | | | | | | | | | | | Avoid using AV_PIX_FMT_NB, since that hardcodes the number of pixel formats into lavfi and will break when a shared lavu is updated, adding new pixel formats.
