Fixes a regression due to the fact that the colorspace filter does not use the new API introduced by 8c7934f73ab6c568acaa. The scale filter uses it since 45e09a30419cc2a7251e, and the setparams filter since 3bf80df3ccd32aed23f0. Example 1 - color_range specified and chained with scale filter: ffmpeg -f lavfi -i testsrc -vf setparams=color_primaries=bt470bg: color_trc=smpte170m:colorspace=bt470bg,colorspace=bt709:range=tv,scale ,showinfo -f null -frames 1 - Before: color_range:unknown color_space:bt470bg ... After: color_range:tv color_space:bt709 ... Example 2 - color_range pass-through: ffmpeg -f lavfi -i testsrc -vf "setparams=color_primaries=bt470bg: color_trc=smpte170m:colorspace=bt470bg:range=unknown, setparams=range=pc:enable='between(n,1,2)', setparams=range=tv:enable='between(n,2,3)', colorspace=bt709,showinfo" -f null -frames 3 - 2>&1|awk "/color_/ {print \$4}" Before: color_range:tv color_range:tv color_range:tv After: color_range:unknown color_range:pc color_range:tv Signed-off-by: Nicolas Gaullier <nicolas.gaullier@cji.paris> --- libavfilter/vf_colorspace.c | 64 +++++++++++++++++++++---------------- 1 file changed, 37 insertions(+), 27 deletions(-)
