I made a low quality gif to explain that weird brightness problem. Quality is low but I can confirm that the difference is what I see in full quality.
The first darker frame is the original. The second is if I tweak brightness with shader or CoreAVC, third is the brightness in DiAVC. If you notice the skin tone in DiAVC seem to go yellow. |

Thanks, it's working.

It might be something within madVR, because with other video renderers it worked fine, but the other AVC decoders work fine with madVR, so it might be something on DiAVC side too... Can you take a look into it? Not using madVR is not an option to me... |

every decoder MUST give the same output quality. a decoded frames must be the same (rounding error permitting) regardless of decoder.
DiAVC is simply FASTER on decoding. BHH

Anyway it is also useful for powerful CPU when encoding with e.g. MEncoder. Faster decoding makes encoding also faster and will leave more CPU cycles to encoding part because decoding with DiAVC is less expensive on CPU. My tests say that on 5:54 min sample(1920x800/x264): - encoding to MPEG2 takes 6:52 with DiAvc - encoding to MPEG2 takes 8:22 with builtin FFMPEG in MEncoder - encoding to MPEG2 takes 7:59 with CoreAvc without CUDA - encoding to MPEG2 takes 6:59 with CoreAvc and CUDA enabled If somebody will ask why to encode to mpeg2.... Answer is PS3MediaServer and realtime encoding to DLNA client with subtitle support = faster and less CPU expensive decoder is a must for realtime transcoding But I have to say that DiAVC output is buggy with MEncoder(from Sherpya) right now(but output with other decoders are OK)...

Does DiAVC properly decode h264 streams which exceed Blu-Ray specs? CoreAVC shows artifacts with several of my Blu-Rays, so if DiAVC has no such problems, that would be a huge benefit over CoreAVC from my point of view.
(I don't care if these Blu-Rays are out of spec or not. They are what they are and I want them to be played back without artifacts.) |

I don't really know which part of the bitstream CoreAVC doesn't like. But I've had more than 5 different Blu-Rays (e.g. Chocolate (2008), Chinese Ghost Story, IIRC) where CoreAVC showed artifacts, while DivX didn't. According to BetaBoy these Blu-Rays are out of spec (not sure if out of Blu-Ray spec or out of h264 spec) and BetaBoy also said that Core is not likely to do anything about it, except trying to convince encoding houses to stick to the standard.
Edit: Yes, it's out of spec motion vectors. See BetaBoy's post here: http://forum.doom9.org/showthread.ph...08#post1345508 So is DiAVC able to decode out of spec motion vectors "properly"? CoreAVC is not able to. DivX is. Last edited by madshi; 16th March 2010 at 19:04. |

Please can you help with finding where is the problem when using DiAVC decoder in MEncoder? When coreavc, ffdshow, Divx or internal ffmpeg is used, encoded video is OK but when DiAVC used, video has something like badly ordered frames,it shutters like on this sample: http://www.mediafire.com/?oty1dqqm2on Sherpya's dsnative wrapper has no problems with other decoders so I am asking, do your DiAVC something in other way than "other" decoders? When this problem will be solved, you can expect money from me I use MEncoder in PS3MediaServer DLNA server so encoding full HD source in realtime is necessary so every additional frame in decoding speed is big deal for realtime streaming/encoding. Many thanks ExSport |
