I'm trying to make a demonstration of orange and blue color timing. I've been told I can do this in the YIQ domain by increasing the level of I and decreasing Q. So I want to take a video, rotate the UV plane by 33 degrees (changing hue so that YUV represent YIQ), change the planes' levels with lutyuv
, and rotate hue back by 33 degrees.
I'm using avconv version 9.18-6:9.18-0ubuntu0.14.04.1
. But it appears to lack the hue filter and the mp=eq2 filter.
avplay -i some_video.webm -vf "hue=h=33"
gave "No such filter: 'hue'"avplay -i some_video.webm -vf "mp=hue=100:0"
gave "No such filter: 'mp'"
What do I need to sudo apt-get install
to rotate the UV plane of a video? Would upgrading from 14.04 LTS to 15.04 add the necessary features? Do I need to compile FFmpeg (not avconv) from source? Or would mencoder
be preferable for this task?
