Hi, I am looking to buy a license for the CoreAVC codec for Windows. I downloaded the trial and I am very happy with the performance. In fact, it is the only decoder that I have found that is fast enough to play back high-bitrate H264 content at 1080p on my machine. (I've long been looking for a solution to play back BD movies on my machine, since it has a BD-ROM drive, but all of the software I've tried has been a disappointment. My GPU is not fast enough to assist in decoding of high-bitrate video.)

In my experimenting with the trial version, though, I have come across an issue that must be resolved before I am willing to purchase a license. I am getting decoding errors when trying to play "Stargate: Continuum." I am using the encode straight from the Blu-ray disc. I do not have any other Blu-ray movies that I can try (I want to make sure I can play this one before I go out and buy more). Here are a couple screenshots showing the decoding error.

This error always occurs on the bottom half of the screen and pops up frequently throughout the video. I haven't touched any of CoreAVC's settings, everything is default. I am wondering if there is something I can click to fix this, or if it is actually a problem with CoreAVC. (The video plays properly using libavcodec / ffdshow... although it is not fast enough to decode the video in real-time.)

If I can get this figured out, I will purchase CoreAVC right away. :-)

(Another note... yeah, I saw this thread that mentions that the encoded video does something that the AVC spec does not allow. That's silly, though, since other decoders play the movie fine, and this is a professional encode from a Blu-ray disc; if CoreAVC doesn't play it right, I don't know what other movies it will break on, and that's a deal-breaking issue from my perspective.)

Thanks!

Alright, in that case I will wait for 2.0 and then check again.

Thanks for your reply! Glad to know that a fix is in the pipe.

Yeah, I know, from your perspective, it's just a bad video and CoreAVC is working as designed. But from my perspective as a user, I tried to play a video using CoreAVC and it didn't [completely] work, so if it is fixed, I am happy.

I don't suppose you have any timeline for the 2.0 release... :-P

Ha! You found me. :-P

you shouldnt blame a codec developer for an encoders screwups.

also your choice of CCCP is IMHO a bad one, they update far to slowly on the non-beta versions, thats why i dropped it.

try this http://shark007.net/win7codecs.html its updated regularly and the performance of its decoders/filters is FAR better with FAR fewer bugs/querks then the current "stable" CCCP release.

Not saying cccp is bad, but their dev is SLOW, I got tired of having to manualy update ffdshow and other filters/files myself because they go for a year or more without a stable update.

example: cccp h264 decoding was using 40-60% of 1 cpu core on my system to playback a 720p movie, i updated manualy to the latist build of FFDSHOW(tryouts i think it was) and that dropped to 20% or lower........

and the CCCP beta offerings can brick your system, they say as much at the top of the page.

current stable cccp= 9/21/2008 thats close to a year old!!!!!!
alot of improvements come along in that year....

the current Win7CP(linked above) and VCP(for vista and older) where last updated 2009-08-11, bit of a deference there, and if you find a bug, shark007 will do his best to fix it asap

so my advice is if you cant use coreavc try the latist VCP or W7CP from http://shark007.net

a 2.4gz core2duo shouldnt have any problem playing back 1080i/p movies, My old athlonXP media center system can do it and its a POS (1.9gz athlon xp, 1.5gb ddr, 256mb x1300 video) CoreAVC is still the better choice on that system, but it CAN DO IT WITH FFDSHOW's current avc support.

Hey, thanks for your input.

First off, I don't have any trouble playing 1080p h.264 content on my computer. It's only very high bitrate content that causes trouble (i.e. the Blu-ray rip). I've played back lower bitrate 1080p h.264 without issue and it looks great.

(I also run Linux on-and-off on my system and I've tried playing the same rip there with similar issues --- simply not decoding fast enough --- and I imagine Ubuntu has a slightly more up-to-date libavcodec in the current version.)

Secondly, I know the CCCP is not updated very frequently. Before I picked it up, I actually manually installed a recent FFDShow-tryouts package, Haali media splitter, DirectVobSub, etc. I got tired of trying to keep it all up to date, and when I found that the CCCP offered a package that included everything I need to play most videos, plus everything was installed, pre-configured and ready to work right, I thought, "great." So, part of the reason I like it is that I don't want to have to bother keeping stuff up to date. Install it and forget about it, that's what I like. (I also have noticed any "bugs/quirks" like you mentioned, everything I try to play works fine, except for my high-bitrate h.264.)

Nonetheless, I will check out the alternatives you mentioned. They may well offer some of the same advantages that I just mentioned, and suit my needs better.

VCP/Win7CP is effectivly the same concept thats behind CCCP, just that shark wants to keep it up to date.

You only notice querks on some files and some systems, or some driver versions, for a while there it was REALLY BAD for nvidia users with gf8 cards, broken yv12 color spacing (made shows/videos look like u watching them on an old tv with rabbit ears mad of foil)

I got sick of having to update CCCP's packeges myself, thats what drove me to give VCP a try and since then, I havent had any complaints or need to dig around and find updates myself.

as to ubuntu.......well its a horrible distro, easiest anniligy is to compair it with vista pre sp1, slow, bloated and a pain in the butt at times.

If your truely a linux fan try a slack based distro like one of the following

http://vectorlinux.com/
vector is light, fast and easy to use, I have run it on anything from a p233mmx with 208mb ram and a 5.4gb hdd all the way up to a current amd or intel quadcore, it runs damn good on slower hardware making the system feel like you upgraded it(even KDE on vector is FAST)

http://wolvix.org/
another good slack based distro, but a bit more work to install last i checked(not a gui installer, a text based one)

http://www.zenwalk.org/
another great little distro based off slack.

http://en.wikipedia.org/wiki/List_of_Li ... ware-based

Ubuntu is good to show people some of what linux can do, but its far from the best distro out there, if your really a linux fan, try some other distros, hell if your really fond of debian based linux(ubuntu) then why not download debian

Actually, I do have a CUDA-compatible card. When I enable CUDA, though, decoding is waaaay slow. So no good. :-P
