[Mvpmc-devel] Picture gallery

[Pete S. <ps...@gm...>]

I have been playing around with a photo viewer for MVPMC and have some
success running it under X-windows on the development host. However, the
real MediaMVP behaves a little bit differently. Most of my problems seem to
stem from trying to do mvpw_.. or Gr.. functions in my working thread. They
just hang with no CPU usage.

Is there something I should do to allow a thread to perform Nanox functions=
?
Does each thread need a GrOpen call?

Specifically in the latest trial the (modified) mvpw_set_image does a
GrLoadImageFromFile and never returns. (I admit to having failed to
understand the Nanox client server mechanism. GrLoadImageFrom File allocate=
s
an nxLoadImageFromFileReq and fills it in and then looks for a response -
when does the request get sent to the server?) Is the LOCK and UNLOCK of
nxGlobalLock coming into play here?

Also what is the significance of the switch_hw_state function? Is there any
mvpw_ or mvpmc documentation?
