Is there some general software library which would have the conversion
function ready to be used?
Also if really from the official kernel distributions the decompression
function has to be taken off, I think there should be then some pwc.so,
which would support decompression and all the most usual colorbase conversion
functions.
Maybe even done such a way, that if someone oneself wants to have that
stuff in the kernel, (s)he could just compile the kernel pwc.ko with
some switch (-DINC_USRF) and it would then include the functions from pwc.so
with some clever transparent way to the kernel driver.
Because there always will be programs which just want to use v4l-device
and do not understand to use some user base library in the middle. It will be
cumbersome to have to patch and recompile every one of them by some user
which uses pwc-driver.
I don't know, maybe V4L2 has some standardized way to provide
information from the kernel driver to the application that it (the
application) could/should also load some userbase software library to
increase the functionality of the kernel driver.
