Lag with decodingAccelerated: true
In fact I see 3 bugs:
doTransfer is True even if video-split is not used yet (cf Conference::sendConferenceInfos(), no delay if createSinks is commented). This must be false if sink is not used. This means that registerSinkClient is done in LRC even if sink is not used
HAVE_SHM is true if libwrap is true in LRC. We should change the configure to have enable-shm with dbus and not with libwrap.
HardwareAccel::transferToMainMemoryis called for every participant, for every sink client. It should be done only once and then cropped by the sink clients.
