Xvid Encoding:
We tested video encoding performance using VirtualDub-MPEG version 1.6.15 and a multithreaded version of the Xvid codec, along with the LAME MT MP3 encoder for encoding audio. We did a two-pass encode of a 15-minute 276MB digital TV recording with a target file size of 100MB.
Again the memory timings and therefore bandwidth coming into the equation causing a slight lengthened encoding time of 30 seconds over twenty minutes. This isn't as drastically bad as it sounds and is 20 seconds faster still than the RD580 ECS board.
MP3 Encoding:
We used LAME MT for our audio encoding test - it's the multithreaded version of the popular LAME MP3 encoder. We ran tests with both Intel's and Microsoft's compilers - naturally, the Intel compiler resulted in some performance increases on Intel's processors. We converted all 18 tracks from Moby's popular Play album to a 192kbps variable bit-rate MP3.
Across the board, with either Intel or Microsoft compiler the ST27P2 performs on par with the rest of the crowd. A second here or there is within testing limit acceptance.
