Public bug reported:
Binary package hint: libxvidcore4
After an upgrade from edgy to feisty I noticed that Xvid transcoding was
significantly slower.
e.g. mencoder blah.avi -ovc xvid -xvidencopts bitrate=2000 -nosound -o blah.mp4
Reverting to the edgy libxvidcore4 (2:1.1.0-final-0.1ubuntu1) fixed the problem.
Switching back to the feisty package (2:1.1.2-0.1ubuntu1) again produced the
slower performance. No other libraries were changed.
Building libxvidcore from source produced a package which performed
badly as per (2:1.1.2-0.1ubuntu1).
Reading the doc/INSTALL I noticed this in the build Requirements:
- nasm on ia32 platforms for MMX/SSE optimized code.
Installing nasm and rebuilding the package produced a libxvidcore that
performed at least as well as (2:1.1.0-final-0.1ubuntu1).
So I'm guessing that (2:1.1.2-0.1ubuntu1) was built without nasm.
