<div dir="ltr"><div><div>Thanks Sebastian. Should have seen that myself. Seems like the
alpha plugin can convert I420 to BGRA pretty much like videoconvert
though it add the feature I suggested, but with more sophistication.
Unless it has a different setup, I could suggest to merge videoconvert
and alpha, but that is just an oppinion.<br><br>I assume it is safe to
expect that the alpha plugin is using the same YUV to RGB conversion as
videoconvert. At least it is using a similar high amount of CPU as
videoconvert for 1.2.2. I also assume/hope this is fixed in 1.3 by the fix you guys and girls did for videoconvert?<br><br></div>Kind regards<br></div>Peter Maersk-Moller</div><div class="gmail_extra"><br><br><div class="gmail_quote">

The alpha element can do that with the target-r, target-g, target-b<br>
properties. It's not really in the scope of videoconvert, which really<br>
just converts between raw video formats.<br>
