7) Install coreavc with wine, or just copy the CoreAVCDecoder.ax file into /usr/lib/win32. Create this folder, if it’s not there yet.
wine coreavc_professional_edition-setup.exe
mkdir /usr/lib/win32
cp "$HOME/.wine/drive_c/Program Files/CoreCodec/CoreAVC Professional Edition/CoreAVCDecoder.ax" /usr/lib/win32
8 ) Test your dshowserver:
dshowserver -c CoreAVCDecoder.ax -s 1280x720 -g 09571a4b-f1fe-4c60-9760de6d310c7c31 -b 12 -f 0x34363248 -o 0x30323449

9) We’re almost there. Now start mplayer:
/usr/local/bin/mplayer -demuxer mkv -vc coreserve my-matroska-movie-here.mkv
Now you should see a window with your playback. Use the command 'top' at a command line and see if dshowserver is running (should be at the top position), and press the key ‘1‘ to see how dshowserver is utilizing your CPU cores. If it also works without the ‘-demuxer mkv‘ switch, leave it away.
If you don’t see a video, and you can hear sound only, check, if your mplayer have really been built recently. Check it like this
it should have the current timestamp:
ls -l /usr/local/bin/mplayer
-rwxr-xr-x 1 root root 9267480 2008-10-23 22:38 /usr/local/bin/mplayer
If you still can’t get it to work, please check the coreavc-for-linux site for updates.
NOTE: The playback of AVCHD footage from my camcorder (Canon HF100) doesn’t work properly. I’ve got only a few frames per second. I’ve addressed this issue already. Use the search function in this Blog.
For AVCHD playback you should use for Panasonic the lavf demuxer or for Canon the -fps 50 or NTSC 60 switch. See also here in this Blog. But like already mentioned: It’s not working atm.
Please report errors. Thanks.
While following your instructions, I encountered this error when trying to patch:
Reversed (or previously applied) patch detected! Assume -R? [n]
I said ‘y’ and it compiled fine. However, I don’t get video:
Forced video codec: coreserve
Requested video codec family [coreserve] (vfm=dshowserver) not available.
Enable it at compilation.
Cannot find codec matching selected -vo and video format 0x31637661.
I re-traced all my steps, and now I don’t get the first error when patching, but I still get no video at all with the same 2nd error.
I feel like I’m going crazy, because I’m recompiling mplayer over and over again and getting different results. This time I get:
Forced video codec: coreserve
Opening video decoder: [dshowserver] DirectShowServer video codecs

Hello Erik,
does the dshowserver test work for you?
And could you post here the mplayer command line, you’re using?
Btw: “-R” means to revert the patch, which means “undo the patch”. Unfortunaely it never worked for me, and I had to delete the whole directory, and I had to download mplayer (via svn) from scratch.
It’s also important, that you follow these steps:
1) run .configure first, then
2) patch your mplayer (patch -p0 < ..) 3) make && make install (check the timestamp of /usr/local/bin/mplayer) Additionally your dshowserver test must have run successfully. And be sure, the user for which you appended your $/HOME/.mplayer/codecs.conf is also the user which starts mplayer.
@Erik
Could you please post your mplayer line here? (cut&paste)
and did the dshowserver test run successfully?
The dshowserver test always works fine since the latest patch.
“And be sure, the user for which you appended your $/HOME/.mplayer/codecs.conf is also the user which starts mplayer.”
D’oh! I was running as root. However I still get the above error “sh: Syntax error: รขโฌล(รขโฌย unexpected” Will try another patch and recompile.
for .TS files I have tried:
/usr/local/bin/mplayer -demuxer lavf -vc coreserve -nocorrect-pts /file.ts
For .MKV files I use:
/usr/local/bin/mplayer -demuxer mkv -vc coreserve /file.mkv
@Erik
Does error come from the ‘mplayer’, or from your ‘make’ command?
I Ijust deleted everything and recompiled. That part works fine. The error is when playing a file. IT eventually goes on to play the audio only:

tbh, i’m clueless atm.

could you check the permissions of the affected files and folders?
1) ls -ld /usr/lib/win32
2) ls -l /usr/lib/win32/Core*
3) ls -l $HOME/.mplayer/codecs.conf

Found the problem! I had a version of codecs.conf.orig which contained from previous instructions:

I think you’re missing ht elast 3 lines on your instructions above. Now it plays the matroska, at least. WIll try the .TS now.
Also, I compiled this with the latest svn, #27818. I basically skipped the step to revert.
@Erik
So it was my fault! I’m relly sorry for this cut&paste bug.
Thanks a lot for your patience. I’ve updated/corrected my bug above, and added also the info, that #27818 worked for you.
Again: Sorry, and a big thanks!

Andreas
Well, the Matroska works now, but the .TS files don’t. I get:

@Erik
Well, I can see it’s a H264 encoding, thus it should work actually. (I’m not sure, but I thing VC1 from Microsoft is not supported [FIXME], which also sometimes is used for BluRay).
And I think, you’ve alredy tried leaving out “-nocorrect-pts” and tried stuff line “-fps 24” or “-demuxer lavf”.
And did it worked for you in the past?
It’s never worked with CoreAVC in Linux. It works under Windows XP.
Thanks for the guide!
Now beginning with step 5, could you modify step 4:
patch -p0 < path-to-your-coreavc-for-linux/mplayer/dshowserver.patch
with adding -i, because it didn’t work without it
@Bas
Thanks, I’ve added your version, too.
Hi acmelab68,
I am using Debian testing.
cpu:Intel T2370
display card:intel X3100(Mobile GM965/GL960)
mplayer revision:27872 ;coreavc-for-linux revision:82
I compiled core-for-linux and mplayer follow your instruction and thank you for that.
Now I can player mkv smoothly:mplayer -demuxer mkv -vc coreserve *.mkv.But it is using a little higher cpu than “mplayer *.mkv”.The only advantage is it can let my two cpu collaborate,and it is important.
When I playe the ts file with the command:mplayer -demuxer lavf -vc coreserve *.ts,an error came.

All my *.ts files are VC1,so can not be supported by coreserve.Right?
@LaoLiulaoliu
Well, I’m not sure about that. At least it seams to be right for Linux. And without CoreAVC on Linux it’s damn slow -> unusable. Sorry, that I can’t be more precise about that, but I’m simply don’t know.
Thank you.I know the result.
Is there a method for using CoreAVC 1.8.5 for Ubuntu 8.10 32Bit?
@Jeremy
Read here the complete wiki documentation: http://code.google.com/p/coreavc-for-linux/w/list
32Bit is actually the the default target platform
FYI – I got this working on Hardy (32-bit) using the latest SVN revisions of mplayer (rev:29001) and coreavc-for-linux (rev:82).
Thanks for the guide, it was a big help! Something I noticed – you need to be very careful when copying and pasting the codecs.conf (step 5). The “x” characters in the hex codes on the “guid” line were not being properly parsed by mplayer, which took me some time to figure out! I was still getting “Cannot find codec matching selected -vo and video format 0รโ31435657” until I replaced the characters using vim.
@Andy
Thanks a lot! I’ve corrected these ‘X’-chars.
And sorry for the mistake.
Andy, do you actually mean revision 27901 ?
@Nicholas Polydor
yes, he’s talking about latest trunk, it’s very likely the error is gone now in the meantime. Just try to run coreavc-for-linux #82 againts mplayer #27903.
I’m running 8.10 Intrepid 32-bit (thought it would be OK due to Andy’s advice) on an eee PC 901. I’ve downloaded both coreavc-for-linux #77 and #82 and all the SVN revisions of mplayer listed above, and have followed the above instructions exactly. However, after multiple attempts, using all these different versions and on both 2.6.27.7-eeepc-lean and 2.6.27.8-generic, I have failed in having a window open and playing video (although sound has played fine).

@Nicholas Polydor
mplayer behaves like this, if it’s unpatched. Maybe you’re just jusing the already installed one.
invoke fully qualified “/usr/local/bin/mplayer -your-switches-here …”
If not, check your ~/.mplayer/codecs.conf for strange chars, I’ve posted accidentally a bogus codecs.conf. Make sure the user, who starts mplayer, is the user who owns codecs.conf. Don’t be root, else you might not be able to open DISPLAY, or invoke as the login-user “xhost +” in command line.
Hey, I have been trying for a few hours, mostly recompiling mplayer over and over again. But no matter what I try to play, I get an:
“Forced video codec: corecodec
Cannot find codec matching selected -vo and video format 0x10000005.”
However, the very end of my ~/.mplayer/codecs.conf is:

”
Now I read something about problems with X’es. Which ones would those be? I edit with nano. The dshowserver test seems to be working fine.
@Johannes Wilm
Hallo Johannes. The lines, which starts with “guid 0x95..”. Replace every “x” to be sure, there’s no special char in this line. I’ve checked my lines above, and it seems correct. Your codecs.conf looks wrong.
Anyhow, sorry for the inconvenience.
@Johannes Wilm
Ehm, well, I just noticed in the example how “coreserve” and “corecodec” were mixed. Even with that fixed though, ti still doesn’t work. I now get a segfault. I’ll compile mplayer with “./configure –enable-debug” and give more feedback on that.
Apparently there is no back-trace, even when compiled with –enable-debug. Well, I have no idea. Any clues?
@Johannes Wilm
1) make sure user is the user for the codecs.(recheck for strange chars in it)
2) check for read permissions
3) ensure the right mplayer is invoked (/usr/local/mplayer)
4) if you’re doing all as root, make “xhost +” as default user, so you can open DISPLAY
5) does dshowserver test worked successfully.
6) dump the mplayer line, you’re using here.
7) are you really on 64bit environment (uname -a)
1) the folder ~/.mplayer and all its contents are owned by user “johanneswilm” who is also executing mplayer
2) of what?
3) I did that, and to make sure I removed the /usr/bin/mplayer
4) am not doing it as root
5) yes
6) mplayer -fps 60 -vc coreserve johanneswilm.mts
7) no, but I recompiled dshowserver and registercodec on my machine, so they should be 32bit, right? I run i686 on a Macbook Intel 2 core…
@Johannes Wilm
Sorry, but I really don’t know.
You could try (If you not already did) to post your problem here: http://code.google.com/p/coreavc-for-linux/issues/list
I think it’s the right place, although it might get not that interactive like it is here.
Sorry.

would you please post your mplayer line?
I have just got mplayer and coreavc working.
Computer: Acer Aspire One (Intel Atom 1.6GHz, RAM 1Gb, HDD 160Gb)
OS: Ubuntu 8.10
Mplayer: 1.0rc2 (I got it from packages.ubuntu.com)
coreavc-linux: r82
coreavc: 1.8.5
I had to apply the patch manually since the patch does not fit the mplayer source perfectly.
I tested it with 1280×720 H264/AAC MKV file. It works well (no lags), but the picture sometimes get pixelated on fast scene. I am still trying to figure out what the cause is.
If anyone need more information about this, please let me know.
One more thing, I also needed to modify a bit the codecs.conf.
I have just compiled mplayer r27949 with coreavc-for-linux r82 successfully. Now, it can play most of my 1280×720 H264/AAC files perfectly. It does not get pixelated anymore on fast scenes.
However, if I activate ASS rendering on some files whose subtitle contains Japanese characters, It lags badly. The workaround for this is by disabling the ASS rendering. Does anyone know how to actually solve this problem?
With the latest revs, I used the build_patch.pl script in the mplayer directory like this …./build_patch.pl . |patch -p0 and it worked.
Sorry, I was wrong, I tried to apply mplayer.patch…
Dont forget that for OSD you need the libfontconfig-dev and the libfreetype6-dev packages…
@chx
hmm, good point. And mplayer’s ‘./configure’ does recognize the presence of these additional libs on its own, and handle the rest automatically, right?
dhanar_10, I guess you installed dshowserver r82 according to CoreAVC revision, didn’t you?
Where did you get dshowserver r82 source to compile or the binaries already compiled?
It’s all here: http://code.google.com/p/coreavc-for-linux/source/checkout,
except the last binary for the x86_64 edition. As far as I can see, I’m the only one who’s offering this for download atm. But of course you can compile it on a 32bit machine with the STATIC=1 switch, and use it on a x86_64 box then. It’s just some people don’t have two machines to complile on, or even some don’t know how to compile at all(yes, they are out there ๐
Actually I meant the static build, I realized the source code comes with coreAVC. I tried to compile myself with STATIC=1 but I got some errors. My O.S. is also Ubuntu 8.10, could you upload to megaupload dshowserver and registercodec already compiled???
Did just “sudo make -C STATIC=1” work?
I got some error compiling loader too.
Thank you very much
@Viper
Sorry, I though we are talking about this one: http://blog.mymediasystem.net/?p=727
I’ve build already an binary package for x86_64 Ubuntu 8.10. Just download and install it like described.
Btw: There are other interesting posts regarding H264 acceleration in this blog. Look for “vdpau” or NVIDIA, they’ve got hardware acceleration working now for NVIDIA cards. (Beta!)

i used coreavc-for-linux after following your instructions, and it worked perfectly! Still, a few days ago i discovered the multithreaded ffmpeg version, and mplayer’s playback is less CPU-intensive that way in my system, compared to coreavc-for-linux. If anyone is interested, follow the instructions of the first post, it worked just fine for me!

@evelkeneevel
Thanks!
Almost lost ffmpeg-mt out of my focus. Actually it was the first thing I’ve tried at all, before I began to focus on CoreAVC.
Few month ago only a few repository changes were made over a couple of weeks, and this made me think the whole project it doomed to die somehow.
I’m really glad they’re alive and kicking.
