nice, but this has nothing to do with coreavc

not bad, but ogg vorbis volume goes down quite a bit compared to radlight decoder

what do i do with CoreAVC.ax so mpc will recognize it?
when i uninstall ffdshow it resorts to nero for x264 playback

register it

When you get time, it would be really great to add RGB24 output to your decode filter, thanks!

Or even RGB32, choosable from a control panel inside the filter.

Version 0.0.0.4 Alpha (20060113) works very well in my case. Plays all 1080-videos smoothly on an Athlon 3500+ (at least with mpc in overlay mode). Good work!

Well actually the conversion is done just right, but there is a difference with video and PC levels. In video levels reference black is at 16 and reference white at 235 (0 and 255 in PC levels).

It is problematic for mixed use PCs. One either calibrates display for video or PC levels, but not for both. One can also expand the 16-235 range to 0-255 to use with a display calibrated to PC levels. This of course isn't a lossless operation (banding may occur when done at low precision). You can do the expanding with ffdshow 'levels' or only allowing RGB32 output colorspace (with HQ YV12 to RGB32 checked to get reduced banding). And at least on ATI cards the overlay mode does the expanding for you (with 10-bit precision, less banding than with 8-bit). Try overlay for starters.

bond... should we make this a sticky now?

agreed

Thumbs up!

Sirber · 14th January 2006, 17:44

I'm against!

Nothing to see, move along

Why not adding it to the AVC sticky in the decoder section?

[edit]

Ha! like the "ateme beta encoder"

I agree then

Making this thread a sticky must be the best idea I've seen in this thread yet!

Go for it

That must be of the most useless posts in this threads here though ...

As to ideas, I'd wonder if CoreAVC or only the DShow filter could output some stats like Haali Media Splitter does too, maybe some infos about bitrates or maybe also about the connections in the graph for the DShow version and which colorspaces, I really hate that most filters don't show you any nice stats and debug infos. It'd be nice if filters all had this as you always need ppl to get GraphEdit for debugging.

First off,

-I am honored to deserve such recognition from... you,

The top priority right now with CoreAVC is supporting AVC to the fullest (same goes for the Dshow filter), right after that is making it as fast as possible.
I fail to see how much more important seeing info is compared to making and using the application... maybe it's just me.

After some tests, i've found that the "best looking" output of NeroDigital decoder (both in ASP and AVC mode) is because its output is in every case straight to RGB32. In this sense, Nero Digital does itself the color space conversion and fires to the GPU the best possible raw data RGB32.
So, i think that is even more important that CoreAVC, in both versions (filter and exe) supports the RGBs output (and do a best possible color-conversion), to avoid (as said by someone in this thread before), buggy or difficult color-conversions done by the graphic cards.

videomixer9 · 14th January 2006, 20:41

GhengisKhan, I fail to see where I said to put this on top priority, usual feature request as done anywhere without ppl making dumb comments on it, and certainly has more to do with this than you playing the bootlicker imo

As to my idea from before with colorspace conversions, I stated that I don't wanna have it the way it's done with overlay but having the calculation being done by the GPU rather than by using the CPU, last year some compilers were presented that can compile to do certain operations all on GPU and had outstanding performance. This way a performance loss could be kept minimal, however seeing CoreAVC also works for mobile PCs I'd wonder if this would be an issue for code portability, besides only ATI and nVidia really support this, besides you could do all the encoding then via this O_o lol.

Besides this, I'd really wonder if we need all these conversion in the decoders ... I dunno if it gives you quality gain because of actual decoding interaction, but imo there should be one HQ Filter that can do those conversions, and not the cheap hack via using ffdshow for uncompressed video which will prolly work with CoreAVC too

Isochroma · 14th January 2006, 21:28

3ngel: yes! I use the Nero decoder for MPEG 1/2/4/AVC for that exact reason, though ffdshow with output set to RGB24/32 only works well - excepting the brightness difference.

3ngel · 14th January 2006, 21:36

@Isochroma
Exactly

But at this point i think that NeroDigital has an upgear in the space-color conversion routine too, comparing to FFDShow (not considering the brightness problem). Even in RGB32 i found FFDShow inferior as global visual effect compared to ND.
I hope CoreAVC developers, will take good suggestions from our experiences

how can i use the CoreAVC codec in WMP 10 ??

I've included some installation instructions (and "bat" files) to the latest version of CoreAVC_DSDec.zip

Hope that helps you out

Cheers

actually i wont make this thread a sticky, cause i am absolutely against making discussion threads sticky

being sticky means carrying general information people should look at before posting and using search
a 20 and increasing pages discussion thread is definitely not useable for this

if we dont make such a limitation there could be lots of threads with some useful info somewhere being made sticky, which would definitely be an overkill

that said, if you want coreavc info in a sticky, wait till i update the info and decoder thread with coreavc
