I have three grayscale videos, representing the red, green, and blue channels from a video. I extracted them using the
extractplanes filter, and sent them through different pipelines.
Now I would like to combine them again. But while
extractplanes is working perfectly,
mergeplanes is not. My initial attempt was this:
[r][g][b] mergeplanes=0x001020 [output]
This interprets my RGB channels as YUV, which is not what I want. My next attempt was this:
[r][g][b] mergeplanes=0x001020:rgb24 [output]
But according to the error message,
Only planar formats with more than one component are supported. (Same for all other RGB and RGBA pixel formats I tried.)
Is there another way to put these channels back together? Or some way to convince
mergeplanes to output RGB?
