The problem with PNG (or any other format really) is that you not only need to
encode the image into the target format (PNG or JPG would require external
libraries, simpler formats such as BMP or PNM could be handled internally),
but you also need to convert the image to a particular RGB or YUV format
depending on what the output format requires.
Yes, that's the "hassle" part I was referring to =).
Maybe we need to invent a new file format that can store all kinds of
formats? (https://xkcd.com/927/)
If you want to do so, I would like to reuse code from the v4l2convert library.
The code should be moved to a library that doesn't depend on V4L2, as the
current API encapsulate conversion in other operations. Other tools such as
raw2rgbpnm could then be ported to use that library;
Yep, so I agree that doing color format conversions shouldn't really be
kms++'s job, but at the same time I'd like to be able to export
framebuffers.
And I'm fine with adding dependencies to kms++, as long as all those are
optional.
Aren't there "big" image conversion libraries that would do the job?
Imagemagick? Or something? I have used "convert" command to do some
conversions, that comes from ImageMagick.
