I've started hacking on SpeciaLib and such again, and SpeciaLib is almost
to the point now where I'm going to check in a fully-functional version.
I spent my time waiting to be called for a jury yesterday writing 250+
lines of Python that will generate the header and stub for an
object-oriented library such as libbitstream, to complement the 250+ line
script that generates header ans stub for normal mess-o-functions
libraries. I'm going to add another 50-100 lines to each now to deal with
literate-programming / gtkdoc style comments to make architectural
specifications suck less.
Then I'm gonna work on the scripts to deal with metaspecialization, e.g.
that used to construct multiple version of the mcomp.c file in an mpeg
video decoder.
Another thing I might look into, once some of the build issues are dealt
with (need a script 'specialize' to run before automake that will generate
Makefile.am's), is the ability to automagically build non-PIC versions of
libraries, and on demand by the application actually load up those
(potentially faster) versions with libol.
My immediate application goal is the next generation of libdv, which will
be based on all of this stuff. Then I'm gonna take libdv and create a new
codec that's optimized for other uses, specifically realtime PVR
operations.
In any case, things are happening here...

Either way, you all should be on the > list ;-) Earlier today, I added libaudioresample, which was copied from gst, autoconf'd, and hacked up a bit. The plan is to use this as a testbed for optimization, since it uses a fairly simple, but non-trivial algorithm that could be optimized serveral different ways. dave... |
