[UPDATE] Alan fixed the Segmentation Fault issue for CoreAVC version 1.8.5.0, so Matroska files can be played back again. See this thread at his project site: #62. Thanks a lot Alan!
Playback of AVCHD still doesn’t work. Read this workaround for playing back AVCHD footage without CoreAVC.
On 17th of October CoreCodec released their decoder CoreAVC version 1.8.5.0.
It’s not working for Linux at the moment. This is what happens if one one uses the dshowserver to test the functionality (like described here) of the new CoreAVCDecoder.ax library in /usr/lib/win32:
/usr/bin/dshowserver -c CoreAVCDecoder.ax -s 1280x720 -g 09571a4b-f1fe-4c60-9760de6d310c7c31 -b 12 -f 0x34363248 -o 0x30323449

Hi!
I’ve been trying to compile mplayer with this patch so the latest version of CoreAVC will work but I’m having trouble getting it to work. Could you please post a PKGBUILD or something if you’ve got it? The ones I find are too old to work.
btw: great work with this! CoreAVC is the only solution when it comes to 720p and 1080p for me so I greatly appreciate your time and effort. 🙂

Hello,
I’ve built a binary x86_64 Ubuntu 8.10 package here: http://blog.mymediasystem.net/?p=727&preview=true
I’m working on the i386 package too.
Hope it works for you.
