So long as the extended fields are _scalars_ (e.g. not pointers), and the first .size field is correctly set, the VISA APIs (e.g. VIDENC1_create()) _do_ support extended create param structs. This is described a little bit here, though the focus is on extending process() and control(): http://wiki.davincidsp.com/index.php?title=Extending_data_structures_in_xDM Chris > -----Original Message----- > From: davinci-linux-open-source-boun...@linux.davincidsp.com > [mailto:davinci-linux-open-source-boun...@linux.davincidsp.com > ] On Behalf Of Stephen Berry > Sent: Thursday, February 26, 2009 6:47 AM > Cc: davinci-linux-open-source@linux.davincidsp.com > Subject: Re: using extended params for MPEG4 encoding > > > > Vladimir Pantelic wrote: > > Stephen Berry wrote: > >> > >> Vladimir Pantelic wrote: > >>> Stephen Berry wrote: > >>>> the routine follows.
