I want to connect vaapipostproc to v4l2sink without any additional element in between (copy). But I can't link these two elements. I let vaapipostproc generate I420 format and do some scaling but it only works if I put a videoconvert between vaapipostproc and v4l2sink. vaapipostproc ! video/x-raw,format=I420 ! v4l2sink : NOK vaapipostproc ! video/x-raw,format=I420 ! videoconvert ! v4l2sink : OK But the additional videoconvert introduces another copy (I assume). The thing here which doesn't match between vaapipostproc and v4l2sink is the colorimetry. vaapipostproc produces in my example a colorimetry of 'bt709' but v4l2sink needs a colorimetry of '2:4:7:1'. Is there a way to create this pipeline without a videoconvert? </pre> </blockquote> <pre wrap=""> In practice, if the colorimetry does not match you need a converter. But if correct correct (only slightly for this case) does not matter to you, you could use capssetter element to make it ignore that field (you need to set fixed caps and set the replace property to TRUE).
