Hi Guennadi,
The mx2_camera driver is allocating one "discard" buffer of the same size, as regular buffers for cases, when the user is not fast enough to queue new buffers for the running capture. Arguably, this could be aliminated and the last submitted buffer could be re-used until either more buffers are available or the streaming is stopped. Otherwise, it could also be possible to stop capture until buffers are available again. In any case, this is the current driver implementation. As for 2 buffers instead of one for the actual capture, I think, gstreamer defines 2 as a minimum number of buffers, which is actually also required for any streaming chance.
Thank you for clarification... regards Jan -- Tato zpr?va byla vytvo?ena p?evratn?m po?tovn?m klientem Opery: http://www.opera.com/mail/
