Xvid 1.1 final ist draußen,...
| Zitat: |
This is XviD 1.1.0 release.
This release is the long awaited 1.1.0. It is mostly API compatible with the previous stable release as we dropped support for reduced resolution coding. If your application didn't use that feature then the upgrade is totally compatible.
Changes since 1.0.3:
* xvidcore:
o Improved Low bitrate quality.
o Improved VBV support
o Rate-Distortion mode decision for bvops
o New postprocessing functions, brightness and deringing
o New PowerPC port by Christoph Naegeli
o Brand new amd64 Linux 64bit port by Andre Werthmann
o Various decoder and encoder speedups
o A few bugs squashed
* VFW frontend
o Mingw/CygWin support
o Various small improvements
o A few bugs squashed
* DShow frontend
o Mingw/CygWin support
o Support for brightness control
o Various small improvements
o A few bugs squashed
Changes since 1.1.0-beta2:
* xvidcore
o Field interlaced decoding
o IEEE-1180 compliant SSE2 iDCT (disabled for safety)
o Fixed misaligned reads on RISC platforms such as ARM
o Completed GCC 4.0 support
o Export only public API on GNU/Linux and Solaris
o Work on the example apps. Support for AVS input in xvid_encraw
* VFW frontend
o Small updates
* DShow frontend
o Additional fourcc support |

in den Thread hier kommen dann immer die Updates des 1.2er Zweiges.

Patch for P- and B-frames from sysKin applied by hand.
- {xvidcore} Trellis improvements (according to sysKin).
- {xvidcore} Bumped bitstream version to 42, you never know (41 is XviD-1.1.0-final). |

So, here we go:
What happened: Multithreaded XviD code is now committed to CVS. From now on, all "xvid head" or "xvid 1.2.x" versions have it.
What does it mean: If you have a multi-core, multi-CPU or just Hyperthreaded system, you get more speed by using new multithreaded capabilities. If not, you can ignore them completely. In fact you are recommended to ignore them. Everything below only applies for number of threads > 0, for equal zero there's no difference from before.
How to use it: In VfW, the number of threads can be changed by clicking on Other Options at the bottom. When using xvid_encraw, use -threads parameter. You need a new xvid_encraw for that (compiled today or later). In general, use number of threads equal to your number of cores. You can make your own measurments though - for example, fast first pass seems to be a bit *faster* on just one thread... But all that depends on your setup, settings, complexity of avisynth script etc.
Is quality lower: No, resulting file is (should be) the same regardless of number of threads.
Is there a maximum: I think a value that's waaay to high will cause a crash and that's my fault. In theory, the maximum # of threads that can be used is equal to picture height divided by 16, rounded up.
Is there an option that b0rks it: Not as such. However, GMC remains not multithreaded at all, so if you use GMC you probably loose most benefits.
CPU usage is better at number of threads = 3 than = 2, should I use 3 then?: DO NOT, I repeat, DO NOT measure this code's performance by looking at CPU usage in task manager. Measure speed. In fact I get the best speed at two threads (85% cpu usage) three (~95% usage). That's the way it is.
So, can I increase CPU usage because 85% is only 85%: Yes, increase thread priority. On a dual-core system it doesn't hurt anyway, and the higher priority the less idle CPU. You probably shouldn't feel any difference, while "Higher" gives me 98% usage and is faster than "Normal". HOWEVER, "Highest" is slower again. In fact MUCH slower. Probably takes CPU power away from avisynth.
I'm looking forward for your impressions, speed results, and crash reports
Regards,
Radek |

Nö, mit der Version noch nicht (keine Zeit), aber der SMP build von Koepi (experimental 1.2.7 oder so) hatte bei mir einen Speedup von ca. 10-15% gebracht,...
