and you know something about coreavc?

[tetsuo55]

sorry, how does this work?when you upload the image to imageshack, when it finishes you get 6 links to copy, one of them is named Forum(1)
He means: just put a link to your image. Don't display it in this thread.
And IMO you should use Jpg instead of png. Png is not adapted for video...MPC-HC saves lossless png's as screenshotsand you know something about coreavc?

edit: and of course ReClock

Both do not have publicly available 64bit versions yet afaik

[hoborg]

Yep, worlds not ready for x64 yet :)

PNG is perfectly suited for video in many cases.
When comparing encoding settings or looking for decoding/encoding artefacts, you want to keep the picture as close to the original, which PNG does perfectly. It does produce much bigger files, but that's a moot point.

[pirlouy]

Png is useful when comparing 2 images quality. When it concerns a graph and some text information, you can convert png in jpg. But now I know MPC-HC does png by default, I can understand users won't convert them in jpg (by laziness). :)

[THX-UltraII]

I made a comparison for .mkv files between the CoreAVC 1.9.5 decoder and the MPC-HC internal H264 / AVC (FFmpeg) decoder. To my surprise their was no noticable difference in quality or speed (slightly advantage for the coreavc but only 2-4% of my CPU).

So I ve decided to skip the Coreavc decoder (also because I want to go back-to-basic with MPC-HC as much as possible) and use the MPC-HC internal decoder (no DXVA!). I see that the decoder has 5 options and I would like to know which does what and what config gives the best PERFORMANCE with no artifacts. (my pc is fast enough)

1. decoding thread number (1,2,3,4,5,6,7 or 8)
2. H264 skip deblocking mode: non, default, non reference, bidirectional, non keyframes or all frames
3. error resilience: careful, compliant, aggressive or very aggressive
4. IDCT algorithm: auto, Lib Mpeg2 MMX, Simple MMX, XVID or Simple
5. read AR from stream: check or uncheck

[Keiyakusha]

THX-UltraII
IMHO decoding speed should be in average frames per second, measured through decoding stream as fast as possible minimum 3 times in a row. CPU load is inaccurate and tells nothing in many cases.

And about quality - every decoder should give the same quality, otherwise its just broken.

[shavenne]

Hi,

I have a problem with MPCHC and Hibernate/Standby Mode.
Ehm.... it just doesn't work. The screen goes black but after some seconds it is on again und MPC plays again. Seems that MPCHC blocks the hibernate/standby mode?
I have the newest version from the webpage.
OS is Windows 7 RC, GFX: GeForce 8300.

Does anybody have an idea to get it working? It's a CarPC, so, if I turn off my car the pc normally goes in standby mode. When a movie/musicvideo is running, it doesn't... :(

[hoborg]

Hi.
MPC-HC devs, if you have time, can you look on this (http://forum.team-mediaportal.com/codecs-external-players-55/haali-not-disposed-after-stopping-video-56153/index11.html#post510587)?

Looks like there is a bug in standalone MPC video decoder (DXVA mode, SW is OK) causing crash when trying to remove filter from graph.

[THX-UltraII]

Hope someone can reply on my post from yesterday too about the H264/AVC MPC-HC filter option.

And another question:
I ve noticed that some of my content is played much louder than other. So I played with MPC-HC a little bit untill I came across the build-in audio switcher which I turned OFF after the installation. I turned this ON and checked the box normalize. Now most files seems to be played on a more equally volume. However, what really happens when the volume gets normalized and more inportant, will this affect the audio quality in some way?

[mark0077]

Best explanation I can give is: Normalization is used when multiple channels (more than 1) could possibly be played through 1 speaker. The normalization code will figure out what sort of downmixing its doing, and adjust the amount of input each of those multiple channels can give, so as to limit what gets output to your speaker. The sum of the multiple inputs could originally go above 100% volume so with normalization, with some fancy maths, they can figure out what % / db of input should be taken from multiple inputs, to never give more than 100% output (so this prevents clipping).

It should improve quality, because when mixing multiple channels into one output channel, you could get ugly clipping without normalization to save the day.

but i ve noticed that normalization only BOOST the volume of some of my files and not lower the volume. thats why I wonderer if this is ok;

[mark0077]

For me, I use the normalization in ffdshow when upmixing stereo to 5.1 and yes overall, because I am hearing audio from 5 channels now I may think its overall louder, but the volume from front left and front right for example would be lower than if playing unnormalized....... but overall sounds louder but louder because I am upmixing...

[Lincoln Burrows]

My system: Windows XP/SP3 - 32 bits.

I am having some problems with certain DVDs and the default MPEG-2/Gabest video decoder. The timecode is running, but a black screen instead of the Warner logo from the decrypted DVD project is showed. Then the DVD stops (also timecode stops). And even if I choose "Go to title/chapter X", still shows a black screen.

This time I tested in BSPlayer PRO and PowerDVD, those certain DVDs were absolutely fine. Then I change MPC-HC this way (pay attentions to those settings). And it worked! How strange is that?

My MPC-HC (last version, 1.3.1280.0), is configured this way:

http://img222.imageshack.us/img222/4895/magic00.png

Now, let's see the filter/video decoder settings:

http://img222.imageshack.us/img222/3771/magic1.png
I had to untick the box MPEG-2 Video on "Transform settings". Otherwise MPC would continue using some filter of his own.

Perhaps someone needs to fix the MPEG-2 decoder from Gabest or the internal decoder? Why some DVDs can't work and others can, and Cyberlink's decoder works with all of them? Perhaps a few discs when decrypted are making MPC-HC not recognize them properly? Well, if they work fine with PDVD, then why MPC is bitching about?

At least I can play those same discs in MPC-HC using the Cyberlink's decoder. I believe someone once said the Gabest decoder had some flaws (or maybe those flaws were related to DVD Navigation), perhaps I spotted them now.

[clsid]

People keep using the external settings wrong. Here are some general tips:

1) There is no need to add a filter to "External Filters" unless you want to alter the merit/mediatypes of that filter. Any installed filter is already by definition an external filter.
2) If you set a decoder as preferred, then there is no need to block similar decoders. MPC will use the decoder with the highest merit (the preferred one).

The first post in this topic states that a nVidia GeForce 8500, 8600, 9600 or better is needed to support DXVA. However, the MPC-HC website states that any "nVidia series 8(9)xxx" will do (http://mpc-hc.sourceforge.net/DXVASupport.html).

I'm looking to put together a new Core i7 system and since I don't plan to play any games, my only concern is that the card support H.264 DXVA with bicubic resizing for my 1080p monitor/tv. Will a Nvidia 9500GT do?

Is there a particular Nvidia card(s) that you guys recommend? I want to go with an Nvidia card as they support up to 16 ref frames essentially allowing for support of most L5.1 videos, whereas ATI's cards are more limited, and have driver issues, or so I've read.

Are you sure you want DXVA? Your Core i7 is more than capable of playing 1080p H.264 or VC-1. I own a C2D E8400 and I play 1080p H.264 or VC-1 at 60% of CPU with software Lanczos resizing.

DXVA may be more interesting for owners of slower computers, because, in my opinion, software decoders give slighty better picture quality than DXVA due to the software decoders' post processing.

Another thing, in my opinion, ATI Radeon cards are better for playing videos. I have much more control of settings when it comes to pixel format output and GPU scaling with a Radeon than with a Geforce due to drivers quality.

I use a HD 4550 because I play some games on my HTPC, but if it's for video-only, then even a Radeon HD 4350 is enough for playing 1080p content, DXVA or software.

But this is just my two cents...

I want DXVA because it significantly reduces power usage as well as noise and heat. Certainly on my laptop, there is a huge difference in fan noise and heat output - but I'm not sure if desktop fans are as adaptive.

I'm somewhat surprised by the recommendation to use an ATI card. If you're just decoding H.264/VC-1 content from Blu-Ray then it shouldn't matter, because both ATI and Nvidia cards decode L4.1 just fine. But Nvidia cards support up to 16 ref frames allowing for decoding of just about all L5.1 x264 encodes, which ATI's cards can't do.

I've also read that ATI's drivers have broken DXVA a number of times and NVIDIA's drivers are more stable in this regard.

As for postprocessing, can't the same be done on the GPU using pixel shaders. MPC-HC supports GPU bicubic resizing as well and provides a number of shaders which I believe can be used with DXVA - but correct me if I'm wrong here.

Also, if you're playing back 1080p H.264 content, you're not using the lanczos resizer. I'm assuming you're playing back the videos on a 1080p (1920x1080 or 1920x1200) TV or monitor. In that case, no resizing is necessary. Resizing is only necessary for 720p content.

My HTPC with C2D E8400 works at a forced 50% CPU speed at BIOS, without achieving damaging temperatures. Recent desktop CPU's are quite cool compared to the old days AMD Athlons and Intel Pentium 4, due to smaller die sizes.

You are right.

Can't be much of help here. Always used ATI for graphic cards, and everytime I tried DXVA it always worked. Perhaps I haven't tested with L5.1 movies.

There is a discussion on the ffdshow about the WMV9 software decoder outputing better picture quality than ffdshow due to post-processing that libavcodec doesn't do, when it comes to VC-1 (in terms of deblocking). I wonder if DXVA has those capabilities.

Also, if you're playing back 1080p H.264 content, you're not using the lanczos resizer. I'm assuming you're playing back the videos on a 1080p (1920x1080 or 1920x1200) TV or monitor. In that case, no resizing is necessary. Resizing is only necessary for 720p content.
You're right, the resizing only kicks up on 720p material.

ThanksMPC-HC can't play those decrypted DVDs (don't ask me what's wrong with them, but if I were to guess, I'd say this is MPC's fault), so I tried to make MPC-HC use the Cyberlink MPEG-2 decoder (and unless you see that filter being used on right click > filters (while playing the DVD project), you are not really using (see picture bellow):

http://img245.imageshack.us/img245/8739/magic6.png

And guess what? It's working now! I knew the Cyberlink Video/SP Decoder (PDVD9) was definitely one of them so I just added... and I believe when I set "Preferred" that didn't worked, so I added "MPEG-2 Video Decoder (Gabest)" as well but only to be blocked.

[Inspector.Gadget]

An mpeg-2 decoder should have nothing to do with decryption or parsing. Perhaps there's a problem with the DVD navigator.

[leowong1]

MPC-HC can't play those decrypted DVDs (don't ask me what's wrong with them, but if I were to guess, I'd say this is MPC's fault), so I tried to make MPC-HC use the [B]Cyberlink MPEG-2 decoder.

I guess you have a RPC-1 DVD drive and using Win Vista or Win 7 right? Note that Win Vista or Win 7 do not recognize RPC-1 DVD drive so you would likely get a DVD: Copy-Protect fail error when playing encrypted DVDs on your RPC-1 drive under Win vista or Win 7. The only solution is to either install DVD region killer to "make" your RPC-1 drive look like a RPC-2, or, like what you have done, to use commercial dvd decoder (Commercial decoder works because they emulate a RPC-2 environment even if you have a RPC-1 drive - You were given 5 chances to change your regional setting).

Hope that helps.

[leowong1]

I have a suggestion to MPC-HC's dvd navigator.
Can the program be made to bypass the process of region-checking, or have an option for software region-change so that Win vista and Win 7 users need not install DVD region killer for encrypted dvds to play in MPC? A region-change option would also allow RCE DVD to be played on MPC. It would be much more convenient for Win vista or win 7 users who have a RPC-1 DVD drive to pay encrypted/RCE dvds.
I tried VLC player and all my RPC-1 drives played encrypted DVD under win vista like a charm. It is possible to implement VLC player's DVD navigator?

I didn't know what I was doing, and suddenly it worked!My educated guess would be that you did not disable the internal MPEG-2 decoder (although your screenshots indicate otherwise). By blocking the standalone Gabest MPEG-2 decoder you indirectly also block the internal one because they share the same CLSID.

The Cyberlink decoder loads fine here with an empty(!) external filters section, and just the internal decoder disabled.

And why do you have the standalone Gabest MPEG-2 decoder installed if you don't want to use it?

People that can still remember the 90s Situation of ATI vs Nvidia are surprised how Nvidia improved it's Multimedia Capabilities up to these days (me included) they made a big leap in their Video R&D in some parts they drove right @ the front of ATI, though ATI has still capabilities to change that again, but Nvidia also keeps on improving :)
ATI's chains of fail imho started with the bugged Bitstream support @ the beginning of the HD2400 series Nvidia already owned them big time in stability.
And imho supporting VLD for VC-1 in UVD wasn't really a big win for them either it was nice but since the complexity of VC-1 was so low Nvidias Strategy of seeing no use in it for the Desktop and saving that investment and incorporate support for it only into the low price and Mobile VP3 Core (where it makes economically sense) was much smarter in the end :)
And not to forget Nvidias Open (Partnership) Strategy beginning with Cuda was the major breakthrough especially giving every small Developer access to the SDK, see how that improved Nvidias Playback by now (all the 3rd party reports) especially the Debugging work Donald Graft has done alone on nvcuvid.dll and everyone now in Nvidias Ecosystem can benefit from that is great, as it arrives directly @ the end user and not only via a costly 3rd Party application (like it is or was the case for ATI's everything closed to normal humans only corporate 3rd partys strategy) :)
Big fail in that term was that ATI seemed to completely forgot that they sell Hardware and not primarily Software Licenses for 3rd party corporate Developers to their Decoding Core, whoever it's decision it was over @ Nvidia to start this rather Open Ecosystem Strategy (especially on the Linux side) they owe a lot to this guy/girl as the primary success that ATI has to try to take on now comes from that Strategy :P

I have no idea of the reason of this different behaviour, is there any test that i can do?

But i realized that the DXVA seems work better than MPCHC. On my pc (E4300, 4850, W7 x64) it uses much less CPU, 3-4% instead around 10% with the same .mkv file (720p).....

I guess, you're not using DXVA at all with MPC-HC.

Load your .mkv video with MPC-HC, click on "Space"= "PAUSE", open the "Filters" submenu to see which filters are really in use and make a screenshot. Doubleclick onto the "MPC Video Decoder" to get its properties page and check if "DXVA Mode" is really "H.264 Bitsream decoder..." or not.

If not, open the MPC-HC options "External Filters", load the "fddshow Video Decoder" and "Block" it. Do the same for "DirectVobSub (auto-loading version)" again.

I was trying Splayer, just for fun, nothing serious even because is only in chinese and i dont understand anything. :p

Can anyone confirm this?
What is the reason of this different behaviour?I talked the splayer dev again, we found the reason.

splayer already merged the new gothsync based renderer, which is a lot lighter on the cpu than the current one.
We are waiting for the renderer to actually be finished before merging it.

I guess you have a RPC-1 DVD drive and using Win Vista or Win 7 right?No. I am using Windows XP SP3. And this is the IMGBurn report (AnyDVD and cheating tools were not enabled when I took this picture):

Sample please, if the whole dvd is affected you can edit the dvd so it only containts the main menu or something, and will be less than 100mb for uploading(this way you dont have to use any tools)How do I take a sample and send to you? What files do you require (listed below)?

These are the files from the DVD-project/folder, already decrypted in my Hard-Drive, with help from AnyDVD-HD 6.5.7.1. Look this picture and you will see their names and sizes:

Disc 5, 6.91 GB, from Lois & Clark - 4th season (R4/NTSC/BR edition).

My educated guess would be that you did not disable the internal MPEG-2 decoder (although your screenshots indicate otherwise). By blocking the standalone Gabest MPEG-2 decoder you indirectly also block the internal one because they share the same CLSID.

The Cyberlink decoder loads fine here with an empty(!) external filters section, and just the internal decoder disabled.

And why do you have the standalone Gabest MPEG-2 decoder installed if you don't want to use it?I needed Gabest's decoder because BSPlayer PRO (the free version does not support DVDs) is relying on free or paid MPEG-2 decoders to play those discs. So I had the Gabest decoder installed here, and I guess you are right about blocking one is preventing another from working. But if you look the last page you will see that I have disabled myself the internal MPEG-2 Decoder from MPC, following the block of Gabest's filter. I have tested now Cyberlink's and it's working again with this decrypted disc.

Bottom line: The internal MPEG-2 filter (or Gabest's MPEG-2 decoder) are not capable of playing this DVD-project stored in my HDD. Cyberlink can, for some unknown reason. Maybe this specific DVD was decrypted in a way that MPC-HC is not working properly with, but Cyberlink is, on the other hand. And when I decrypted the disc, I used the default settings, I never enabled (on AnyDVD) things like "Disable UOPs/prohibited operations". It was a straight copy decrypted, only thing I did was to remove the regional code from the disc - and that's all. That's why I don't understand why MPC is refusing to play 3 discs when so far have played hundreds of them, never with a similar problem.

One other thing I noticed in the AnyDVD's changelog was that entry (after the 6.5.7.1 version):

6.5.7.4 2009 08 06
- Fix (DVD): Bug introduced with 6.5.7.1, AIscanner could include unwanted parts of a disc.

On MPC Video Decoder window i clearly see H.264 Bitsream Decoder, noFGT.

Thanks for the info.
I dont know what gothsync is (is maybe a renderer like EVR?) but on my pc theres a very impressive difference on CPU usage.
I hope it will be implemented asap on MPCHC. :)

/edit: i found the specific 3d and tried the available modification of MPCHC. I can confirm the right solution, it uses less CPU than MPCHC.
