有冇好似INTEL既 QUICK SYNC 既野呢???
THANKS

AMD Avivo?

AMD Avivo?

我覺得呢方面AMD做得好差...
Both Tech and Marketing...
Tech落後於Quick Sync無得講, Intel太強
但佢D marketing真係麻麻, 太多名...
以前叫AVIVO video converter, 後來又有Stream API, 整整下又變咗APP, 岩岩剿資料原來仲有個AVT
宜家7系再整個VCE......!!!

2 different kind of technologies.

Quick Sync is fixed function, can't do anything other than trans-coding movies.

Stream (AMD APP) is AMD's OpenCL API, in other words, programmable, can do way more than just trans-coding movies. For example, applying filter on a jpeg/png.

VCE is the evolution of UVD, trying to do some pre-processing before handing over the the SP's of the GPU to process the movie. (Basically, a sub set of QuickSync)

AMD wants to use OpenCL as they are pushing for GPGPU and does not want to create a fixed function unit like Intel.

[EDIT]
QuickSync is fast but its quality is not very good when compare to AMD/nV's OpenCL/CUDA implementation. (Although AMD/nV's OpenCL/CUDA implementation are not that much better.)

你講得無錯~
不過我想講嘅係一個清晰易明有代表性嘅名, 等一般消費者都能夠記住佢代表轉檔快
先不論誰快, Quick Sync同CUDA應該一般消費者都知, 但AMD嘅GPU accelerated tech就未必個個講得出
再者, OpenCL同CUDA打生打死, 雖然大家都係General Purpose, 但兩者向一般消費者展示嘅主要目的都係轉檔
倒不如Intel殺出一個一般消費者想要嘅轉檔專用API...
AMD嘅有x86技術又掌握平衡運算技術, 其實我幾期待APU加一個AMD的Quick Sync...

AMD's marketing department is always famous for sucky names. VCE is no where close to QuickSync in term of the name.

I think simple words like FastVideo alone is already 10 times more meaningful than VCE.

However, this is unlikely going to change in the foreseeable future as AMD is heavily resource constrained at this moment.

In my experience, CUDA trans-coding is even worse than QuickSync in terms of both quality and speed.
For ATI VCE/Stream, I never find a usable application back when I was interested in those thing.
Now I just stick with Handbrake Multi-threaded X86 codepath for simplicity

Handbrake is going to support Quick Sync
