Mediacoder 0.7.1 released with a CUDA H.264 encoder. What do you guys think about it ? Anybody tried it yet ?

Might try it on the 9600GT if you guys are interested in seeing some comparisons.

Post what settings you want me to test it at and x264 settings.

I'll be using this Source video http://www.w6rz.net/1080p25.zip

Post if you want me to use any other source.

UPDATE 1#

Options look promising. Not seen these options in Badaboom.

What's SPS ? and Dynamic GOP ?

UPDATE #2 Will have to hold off, CUDA encoder is disabled due to licensing issues with Nvidia

AFAIK, it's just nvidia's nvcuenc, so it's the same one you've seen everywhere else.

Also, Mediacoder threads were (AFAIK?) banned because of Mediacoder's consistent license violations (Rule 6).

nothing better than getting surprised ! :D Lets see what happens. beginning my run now.

It outputs the same horrendous quality as Badaboom. I've lost faith on CUDA encoders already. I'm not willing to get 4 times the speed with the cost of 4 times the bitrate to achieve the same quality.

What's SPS ?
sps = sequence parameter sets
pps = picture parameter sets
iirc sps/pps are part of the NAL unit encaspulation and the reference video frame (IDR access unit).

- Each slice references a picture parameter set (PPS) to be
used for decoding its VCL data:
• PPS selected by short variable length codeword
transported in slice header
• Contains, e.g. entropy coding mode, FMO parameters,
quantization initialization, weighted prediction
indications, etc.
• PPS reference can change between pictures
- Each PPS references a sequence parameter set (SPS)
• SPS is referenced only in the PPS
• Contains, e.g. profile/level indication, display
parameters, timing concept issues, etc.
• SPS reference can change only on IDR pictures
from: http://neuron2.net/library/avc/h264_overview.pdf page 45
iirc corrently only sps or pps is needed and the option probably let's you choose if sps or pps are used.
