aoTuVbeta6.02 Options

[Anakunda]

Hi, why aoTuVbeta6.02 Compiles are not available @ Rarewarez, could somebody so kind and made oggenc2 + dlls available to public, thankyou

[Destroid]

This test was for multiple reasons: a) to expand my knowledge of DVD video extraction process (heard that CELT did better with 48KHz and figured stereo AC3 converted to WAV would work; b) to test CELT encoding speed in regards to the statement that it was a magnitude faster because of no psy-model and other reasons; c) just another general encoder speed test carried out on a not-so-modern machine. Seems CELT could benefit from optimizations. But anyhow, I ended up putting results here since the OggEnc2 compile (SSE2) above seemed dramatically faster than Venc.

This test focused on lossy encoders aiming for a VBR setting which would result in @100kbps since I figured a DVD commentary track was less complex and needed no 5.1->stereo conversion. I think 100kbps for this material is overkill since there is virtually no audible winner here. Lossless codecs were added to reflect the material was non-complex and easily compressed.

Those were interesting numbers.

I think 100kbps for this material is overkill since there is virtually no audible winner here.

Since it is DVD audio track then even 64-80 kbps will be more than enough (excluding MP3 perhaps)
