[gst-devel] OS X video source released

Just released a couple of pre-alpha/proof-of-concept releases of osxvideosrc:


The oldest version,, uses the Sequence Grabber API, whilst uses the Video Digitizer API directly (the API used by the
Sequence Grabber). I've done some simple testing using gst-launch and
connecting the source directly to osxvideosink, and the performance is
not particularly good (consuming ~100% CPU time). Eventually I tried
using videotestsrc instead, and even that setup consumed ~100% CPU, so
that's when it occurred to me that this might be a problem in
osxvideosink. (d'oh!) I'm sure osxvideosrc has tons of bugs as well
though. :)

The element is, as I said, pretty much alpha, but it should work with
the newer Intel Macs' built-in iSight, as resolution, framerate and
colorspace are currently hard-coded to match that.

I'm not sure how much time I'll have to work on this in the time to
come, so I just thought I'd put it out there for now, hoping that
someone will jump in and help making this suck less. :-)
