Do this instead of exporting raw_pix_fmt_tags via avpriv_get_raw_pix_fmt_tags(). For shared builds this will lead to an increase in the combined size of the lavc and fourcc2pixfmt binaries (because the overhead of exporting avpriv_get_raw_pix_fmt_tags() is dwarfed by the size of the array), but given that fourcc2pixfmt is a test tool that is not widely distributed it does not really matter. For static builds the opposite is true (the rest of lavc/raw.o is no longer pulled into the test tool and the getter can be removed, too). This patch has the additional benefit of removing struct PixelFormatTag from the ABI. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
