Again it's just drawing pictures to a screen. It doesn't require much work at all for a video card just very repetitive labor. Yes he'll lose VMR9 but that renderer isn't really worth it anyway...

I first see it when Kerio starts going nuts about the installer wanting to connect somewhere on the Internet, in this case, an authorization server.

Needless to say, CoreCodec has lost me as a paying customer.

I don't see why you would need it anyway. Is libavcodec too slow for AVC playback for you? Because if it's not all you would get with CoreAVC is some speed and worser image quality.

EDIT: But yes I do agree on the activation being a bad move by CoreCodec.

Yeah, did what you said, but the lag is still there. Oh well, guess I just have to wait for the .avi releases. Thanks anyway guys!

For a while, it was slower with my hardware even at D1 resolutions for source material. However, the tryouts have caught up lately.

EDIT: But yes I do agree on the activation being a bad move by CoreCodec.

While I'm not really questioning activation itself per se (though truth be known, I'm no huge fan of activation of any kind), it's this sneaky, undocumented contacting a server while I'm not aware which only came to light when Kerio told me about it is what has me upset.

I can tell you right now this would NOT sit well with security-minded organizations, especially those where privacy and security are important. I suspect this would not be very HIPAA compliant.

1.2 is already cracked anyway. A lot of good that activation scheme did them...

And low-resolution 2D images are low-resolution 2D images. Rendering them is trivial. Resizing them and doing fancy filtering is not, but you don't have to do that (and in fact, the CCCP defaults have it turned off). A Rage128 will be more than enough.

how would i fix that?

What?! That could hardly happen... Wait, actually it did happen to me once.

Reinstall all your codecs...

Happens often if slightly less than enough CPU is available.

kyuubixn: What's your CPU and what are you using to decode?

[kyuubixn]

what is CPU?

[emptyeighty]

CPU = Central Processing Unit, that is the main chip that powers your computer. To make things easier for you get this tool, go tools -> test render, select the problematic file, let it finish, then go file -> save log and post that log here.

It wouldn't be so much the sound running faster but the video running slower in his case.

I would suspect this to be particularly true if it's an H.264 file and it's running on a slower machine. Anything below a Pentium 4 (Intel) or Athlon XP 2000+ (AMD, and did they ever make such a part?) will more than likely be too slow.

I TRIED EVERYTHING TO PLAY THIS DAMN FILE.. TRIED FROM INSTALLING/UNINSTALLING CODEC PACKS LIKE CCCP AND DOWNLOADING PLAYERS BUT STILL WONT PLAY THIS SH*&TY CONTAINER! IM STICKING TO OLD FILES TYPES COZ THIS MKV FILE DRAINS YOUR TIME AND ENERGY SO SAVE YOUR FRUSTRATIONS!!

[Navel]

Guess who fails.

You guys are being extremely nice, I mean it. It's like the same question over and over again. (Or maybe it's just me having too little understanding)

I'm currently in the process of reading all these pages, can't help myself posting XD

[Nergol]

I've said it before and I'll say it again, the key to understanding .mkv is:

.mkv = .sht

It may be newer than .avi, and .avi may have its problems. It may even need a replacement. Butthatlacement is not .mkv - whoever designed it needs to go back to the drawing board. Bad compatability, craptastic subtitle drawing, dumb stuff like drawing one line of subtitle over another, resource hoggery, and general suckiness means .mkv is not ready for prime time.

[Navel]

The post above mine is an example of a post coming from people that don't know what they're speaking about.

There's an easy way out though: try to find some more info and see why someone would make such an affirmation reading your post. A little help: mkv is a container, it doesn't draw subtitles, it only contains them, a container has no influence on the resources so you simply jumped to a wrong conclusion that magically made sense for you, an advanced container can store inside streams from newer video and audio compression formats that require more procesing power during decoding (you can't stop progress). You are right on the compatibility part though, the best supported platform is a PC with Microsoft Windows while *nix and Mac users have to satisfy themselves with what mplayer and vlc has to offer, but even there things have improved over time. At least under mplayer, from the features usually used on a file only chapters don't work right now.

[Nergol]

Navel;

I know that when I play .mkv files, the subtitles look like crap. What else do I need to know? It's not a superior format for subtitled anime if tough-to-read, weirdly-drawn subtitles in a clunky font jumble over each other. I don't need to explain not liking that.

Look, guy, I'm not a fansubber or an encoder. I'm an end-user. All I know is: .avi work good, .mkv work bad. But that's all I need to know. Anyone who produces anything for other people knows that their job is to make something that works well for the end-user. That's true wether the thing being produced is fansubs, cars, widgets, or baloney sandwiches. If it doesn't work well for the end-user, it's a dog no matter how impressive its spec sheet may look.

.mkv work bad. Boo .mkv

! and @
Seek to the beginning of the previous/next chapter.

Works as intended i would say.

Edit: Using CCCP's SVN22261 build btw.
