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

-DNTSC

for NTSC like conversion or

-DITU_R_INT

for ITU-R integer conversion. Both standars are explained in the referenced wikipedia article. The use of

-DITU_R_FLOAT

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.

Ich bin gespannt, wieviele der Verbindungen jetzt über IPv6 kommen.

Seit heute gibt es twam.info in neuem Look und in Blog-Form. Die meisten alten Einträge habe ich konvertiert.

Viel Spaß damit!
