A few weeks ago, I published my v4l2grab program to grab JPEGs from V4l2 devices.
Today I got an request by email to include support for integer conversion from YUV422 to RGB as descriped by Wikipedia. So I included it and did some style adjustments, too.
You can download it here: v4l2grab Version 0.2
To use integer conversion you have to compile with an additional
for NTSC like conversion or
for ITU-R integer conversion. Both standars are explained in the referenced wikipedia article. The use of
uses the previous floating point version of ITU-R which is default if no compiling options are specified. More information about compilation can be found on the original post.
The current version of V4L2grab can be found on github.
