Applying the same filter many times before output [duplicate]
19 août 2019, par FabiánThis question already has an answer here :
In my video there’s an object that has shades of yellow (more orange-like) and has a solid yellow as background.
I need to output all frames into a png sequence, using a color key filter to replace the yellow from the background :ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.125:0[ckout]" -map "[ckout]" colorkey-%d.png
This removes all the yellow background. However, it leaves some pints of yellow behind, and some items are yellow-themed, so blending isn’t an option for this scenario.
In the end I need to get rid of 4 specific yellow-colors from the frames :
0xfff31b
,0xfae56b
,0xfaec46
and0xeee2a0
. My idea is to run the same filter for every color.So first I tried this :
ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout1];[0:v]colorkey=0xfae56b:0.4:0[ckout2];[0:v]colorkey=0xfaec46:0.4:0[ckout3];[0:v]colorkey=0xeee2a0:0.4:0[ckout4]" -map "[ckout4]" colorkeyrefined-%d.png
Then this :
ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfae56b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfaec46:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xeee2a0:0.4:0[ckout]" -map "[ckout]" colorkeyrefined-%d.png
But both display the same error :
Filter colorkey has an unconnected output.
Is there a way to apply the colorkey 4 times (with the mentioned values) in one go ?
