I'll confirm 110%, building ffmpeg for Solaris 10 SPARC is definitely
possible. The problem is, the Blastwave / OpenCSW build is old as
dirt, and it currently takes a good amount of coaxing to build from a
modern repository snapshot.
One weekend I decided to try my hand at it in support of a SPARC-based
pyTivo server (I wanted to consolidate this service onto the same box
which already serves the video files via ZFS/samba), and had the
foresight to log my results over the next few weekends:
- It worked (please excuse variables etc.that looks nonsensical, as
software development/compilation has never been my strong suit to
begin with, and I was working late into the night each time);
- I opted to keep running ffmpeg on a single P4 with HyperThreading
instead of SPARC.
Of course, your mileage may vary (especially with the amount of
hardware you have in the form of the V890 to throw at the task).

*Very* likely x64 and not SPARC. Cycle for cycle (and dollar for
dollar, if referring to MSRP), they just aren't fast enough for this
type of work.

I too came across Chris Miles' page and it helped a lot. I'm pretty
sure I credit him in my log.

I used GCC, and VIS optimization works, but there's a bug in the
implementation which requires a Sun engineer's patch which I manually
applied ot the code because it never made its way back into the
It's worth mentioning that even with all Sun and US-III optimization
flags set (I had no intention of porting to any other Sun boxes), I
only squeezed out literally a couple extra fps. I think that's in my
Hope that helps,
