CoreCodec/H.264 Codec "CoreAVC"

[BetaBoy]

Sorry guys who just purchased CoreAVC in the past few hours... I mistakenly omited a script... I have restored it and am manually sending the registrations from the past few hours out now.

[ChronoCross]

how long does the link last? My own computer is in storage right now (it'll be unpacked next week).

Just tried new CoreAVC with a bit of the football that's on at the moment, and it seems to be fine with deblocking left on now (and double framerate). Guess it didn't like the stuff I was trying before (which had errors in the stream).

Hi,
Thanks for the update.
Small question about ts-support:
I have a collection of demo captures (ts-files) from several European providers: all interlaced but not mbaff. Now, with the new version of CoreAVC/Haali splitter, some of them play ok, some of them produce a black screen, and some make the splitter fail (Error: First element of file is not EBML). Are there some restrictions that I should be aware of?
All files play fine with CoreAVC and MPC, if demuxed with mplayer and wrapped in mp4.

Try to uninstall the current Haali Splitter.... reboot and then install CoreAVC 1.1 again... make sure that when it gets to the splitter install that 'Enable MPEG TS support' is checked.

If you still have the issue... email a sample file to me via yousendit.com to betaboy@corecodec.com and i'll have Haali review it.

[cookeal]

Still no download link.... second half of the football has started :~(

Thanks I will.

Users that had registered 1.0 Professional Edition have been sent upgrades via email... check your spam folders... then email me if its not there.

[cookeal]

have mailed you - thanks

[maxleung]

Thanks for the clarification on the license process. Basically it matches what TheaterTek uses and I can tolerate that. :)

BTW, the latest TheaterTek allows use of custom graphs and I can play h.264 files using CoreAVC, Haali Media Splitter, FFDShow audio, and DirectVobSub.

I tryed CoreAVC on the today's BBC HD Football match, but found Cyberlink PowerDVD 7 codex runs much more smoother when using VR7 and VR9 modes.
I not had any Lip sync audio issues with CoreAVC, but if I select "Directshow deinterlacing" it runs slower and I get Purple and Green pictures on both Skyview and DvbViewer.

I'm using am AMD Athlon 64 x2 Dual Core 3800 CPU + Nvidia 7800GT + Asus A8N32-SLI/Deluxe Motherboard + DvbViewer GE V2_0_1

Loaded NVIDIA Forceware V91.28 (Beta) Graphics driver on XP Media Centre and NVIDIA AC3 audio decoder.

I also tested it on a Dual Core Intel setup and CoreAVC seems to run faster than Cyberlink.

I'm very happy with both setups.

[works]

Yes, lets get back to the tech issues.

I've now run some more tests with my X2 3800 running at 2.6Ghz and found that I average about half of the actual framerate and my CPU utilization with software deinterlacing and skipping deblocking for b-frames was around 40-50%, utilizing quite evenly both cores. Quite strange. Using 'software double framerate' brings me up to ~33fps, when it should achieve 50, with the same CPU stats. This is the the BBC HD 'Planet Earth' footage.

What-am-I-doing-wrong-here?

[The1]

Hi there,

Wonderfull is all I can say. Performance is so much better then the nearest rival. Cyberlink go back to the drawing board.

Have one problem, using dvbviewer and coreavc. I get a slight freeze when the video buffers get to 1000. Is there any way to get rid of it?

Thanks

and great work guys!!

are you sure??

It's worse than Cyberlink for me

Hi Dan,

How about starting a new thread dedicated to discussing CoreAVC and HDTV decoding?

Maybe Bond could move some of these posts into it too...


Cheers

I tryed CoreAVC on the today's BBC HD Football match, but found Cyberlink PowerDVD 7 codex runs much more smoother when using VR7 and VR9 modes.

Did you change the color space output to prefer RGB32 in CoreAVC properties? I made some tests and it seems using RGB32 has some performance penalties with VR7 and VR9 compared to YUV outputs. I'am not sure what we can do about that.

For me YUV outputs performed similar speed with VR7, VR9 and old overlay mixer.

[tomos]

after stopping cyberlink from trying to take over the decoding of my bbc HD transport stream this worked well.

had to disable the deinterlacing as my 4400+ X2 couldnt handle it without stuttering. smooth without.

[PicardGK]

It is strange. What player are you using?

Could you try benchmarking the same clip with http://haali.cs.msu.ru/mkv/timeCodec.exe selecting CoreAVC? Try different outputs (also Null) and check the CPU utilization and display fps ("dfps" in timeCodec)

[PicardGK]

Could you check the CPU utilization during decoding? In theory deinterlacing doesn't eat that much cpu time, especially if you don't use the double framerate mode. Maybe this is a similar issue as "works" have on his X2 3800...

Also try selecting YUY2 output in CoreAVC's properties with turned off deinterlacing, because at the moment software deinterlacing doesn't support planar YUV modes and maybe the slowdown is not related to deinterlacing, but the different color format used (YV12 vs YUY2).

i will do when i am home after work mate. it deffo affected it tho. i was messing around this morning with a sample i was sent and it was in the 90's% with power dvd v7 and spiking like crazy with core avc and deinterlace enabled from 70-90's% disabled deinterlace and was about 40-60%

didnt see a visual difference with deinterlace turned on or off tho - thats why i wasnt bothered with the performance when deinterlace was turned on. will try the yv12 etc thing tonight :)

Are you sure you disabled deinterlacing and not deblocking? Was it an interlaced sample? Deinterlacing turn on/off should make a difference with an interlaced sample, unless there is minimal movement.

did both originally. then i turned deblocking back on and left deinterlacing off. didnt see a diff really. the image was really clear either way. just no stutter without deinterlace ;)

[tomos]

just checked with logmein.com and its using yuy2 with deinterlacing turned on and yv12 when turned off (according to which is active in the coreavc properties page)

quite a bit of movement as well. the clip i was checking out was to do with tigers hoping around :D

olisun... can you explain further what issues you are having?

[rura]

1.1 is giving me a strange issue where I have to kill the WMP10 process to close it every time I open an AVC. I am running MCE2005 with rollup 2. I have downgraded back to 1.0 for now and it works fine.

[Pasqui]

Is only CoreAVC Professional Edition updated ? I previously registered CoreAVC Standard Edition and I did not receive an upgrade notification (and my spam filter does not seem to be the culprit)

[BetaBoy]

ATM only CoreAVC Professional Edition was updated... we are working on Standard Edition as we speak and hope to have it out late today or tomorrow.

All Standard Edition users will be notified by email on the update availability.

I'm using the latest official version of ZoomPlayer. I'd love to try that TimeCodec, but currently the stuff that I use for testing is in transport stream container and that tool does not support it. I'll see if I can mux the .ts to .mkv.

I think if you are using Haali's TS splitter you can just rename the .ts file to .mkv and open in timeCodec.exe.

[videomixer9]

it should open .ts without any tricks, just type in "*.ts" in the file open dialog under filename and open the .ts

[ChronoCross]

I'm a little dissapointed the lossless problem I reported wasn't fixed. but I was excited to see that some of the other annoyances were. Thanks.

Gotcha, I was having a SUE (stupid user error).

In anycase, I've now got (finally) Haali's splitter to play nice with Cyberlink's decoder, C's own demuxer didn't want to serve any other filters than their own, and have finally been able to objectively test both CoreAVC and Cyberlinks solution.

The only way that I can get the BBC HD material to play even close to smooth with Core is to use the 'software double framerate' that will increase the framerate to ~35 and drop frames in VMR7 or 9 like crazy. This accompanied with deinterlacing errors on text and at the very edges of the image makes it, for now, unusable for me. I get smooth playback (when the source is error-free) with Haali+Cyberlink combo and perfect deinterlacing when using the DXVA (ATI Avivo) option in Cyberlink. And much more graceful error handling. Core indeed doesn't use as much CPU as Cyberlink does, but since as a whole it is unusable for me, I don't really care how much headroom would have got left with it. As it is now, Cyberlink will never hit 100% CPU on my 2.6Ghz dualcore and the only errors I get are already in the sourcefile.

I'm looking forward for updates.

[Revgen]

Have you tried using standard overlay with CoreAVC?

[blubberbirne]

I got a Problem with the new Hali Splitter

When i enable it in mplayer classic, my regular dvb-s (mpeg2) streams don't work. Now picture while Playback :mad:

[pankov]

I too have some problems with the Haali splitter. Mine are concernitg aspect ratio problems with MPEG2 captures and the following message

---------------------------
Haali Media Splitter
---------------------------
Invalid first byte of EBML ID: 00
---------------------------
OK
---------------------------


So how do we contact Haali directly as this doesn't concern CoreAVC

[videomixer9]

http://haali.cs.msu.ru/mkv/mkx.ts.6.exe
some ts parser improvements, other minor stuff fixed

you can find haali on irc on irc.chatsociety.net (irc://irc.chatsociety.net/darkhold). Also I think he should be member of Doom9 forum, dunno if he checks on his messages though, but his last post was today.

[SeeMoreDigital]

Here's Haali's Doom9 contact information...

[BetaBoy]

based on feedback and fixes made plus Haali's new udpates... we will likely come out with CoreAVC 1.1.0.6 by Wednesday/Thursday.

Sounds good. Waiting for Wednesday :)

Performance is great, but repeat playback of .mp4 and .mov files (with H.264 video) is seriously unreliable. Almost every time I play an H.264 video and close WMP, I have to kill a rogue wmplayer.exe process before I can play another video. This occurs not only with my own x264 encodes, but also with Apple's and Nero's movie trailers. This problem does not occur with videos using codecs other than CoreAVC.

I'm using FFDshow to handle the AAC audio and WMP 10 for playback. My PC is a dual core Pentium D 820 with 1 GB of memory and Intel's 945P chipset; the video card is an ATI PCIe X1600 Pro. My OS is MCE 2005 w/ Rollup 2.

Working perfectly here, although i have only tried with MP4 and MKV containers, using encodes from x264/nero etc

1.1 is giving me a strange issue where I have to kill the WMP10 process to close it every time I open an AVC. I am running MCE2005 with rollup 2. I have downgraded back to 1.0 for now and it works fine.
This sounds very similar to a problem I am having.
I posted it over at the CoreAVC forums, but I'll c+p it here (might get a few replies here actually).

"Having a little problem where I can open H264-encoded video's on my main monitor (which my graphics driver has always detected as my secondary for some reason, but it's set as Primary within Windows), but not on my secondary. I have tried both Media Player Classic and Windows Media Player 11 Beta and both have the same problem - the players will freeze when attempting to open the file. They open fine when the players are on the main monitor.

To make things more confusing, some files DO work. I have no idea if these files are encoded differently, though I can find out.

This never happened on 1.0, and reinstalling 1.1 did not solve the problem. Also, disabling deblocking and deinterlacing did not help either.
Setting the H264 decoding to ffdshow did solve the problem, but I'd obviously prefer to use CoreAVC.

All files are .mkv with either AAC or Vorbis audio.

Here's my setup -

AthlonXP 2600+ Barton (@ default clock)
Corsair ValueSelect 1GB DDR 400 (1x1GB)
HIS IceQ Radeon 9800 Pro 128MB (@Core, DHZeropoint drivers)
ABit NF7-S V2.0 nForce2 400
Soundblaster X-Fi XtremeMusic.

Main Monitor - LG Flatron L1915S LCD (1280x1024 @ 75Hz)
Seconary Monitor - LG 26LX2R LCD HDTV (1360x768 @ 60Hz)

If you need any more info, please say."

[lazyn00b]

OK, I can confirm: switching to FFDShow to decode AVC, but keeping the Haali Splitter, solves the problem with rogue wmplayer.exe process. So there must be some problem with the CoreAVC 1.1, at least on MCE 2005 systems.

[BetaBoy]

This bug has been fixed.... any other MAJOR bugs anyone else has found? Oh... btw if you found a problem... please backup the issue by sending me a clip of the problem via yousendit.com to betaboy@corecodec.com and in the notes explain the issue and we will look into it.

I get no sound output with MP3 audio in TS.
Clip here:
http://starwars.hdclips.net/sith/selecttragedy.htm

Edit: It seems that the audio of the clip isn't mp3 but mp2. The Haali Splitter says the audio stream sub type is 00000055-0000-0010-8000-00AA00389B71 which is the sub type for mp3 in ZP which is why it doesn't work. Bug or Feature?

[blubberbirne]

Ok, it know this is the wrong thread, but most of you have captured ts stream or watch them.

How can i cut H264 TS Stream? I test a lot of tools, but most not working with H264 :(

Thx for answers :p
