HOWTO: CoreAVC for Linux installation guide

[bruor]

I had issues with that as well. the best way i found to work around it seemed to be sudo "command". if that doesn't work i did have some success with invoking the command via the launch with custom command option on the right click menu of a file in Gnome.

Thanks.
I forgot to create a codecs.conf.
Now I've done that, using -vc coreserve, mplayer opens, displays a black screen, then hangs.

Well, at least I got my own compiled mplayer.

I got Coreavc running on both an x32 and x64 version of mplayer. The install was pretty straightforward - thanks to these instructions, but the x64 version gave me a bit of a problem. I compiled the svn mplayer under x32 as well as dshowserver as per instructions and once I had everything working in 32 bit I then basically did the same thing with the x64 OS. The dshowserver file did not work correctly with mplayer in 64 bit - it would pass the test but not run. I tried the precomiled x64 binaries noted in the google wiki (dshowserver install) but they did not work either. I then compiled the dshowserver file "on the x32 machine using the added switch STATIC=1" then copied that file to the 64 bit machine and everything came right up!
I use "-demuxer lavf -vc coreserve -nocorrect-pts " to play either a TS or M2TS file.
Hope this helps someone! BTW, the colors and sharpness is A LOT better than the x.264 decoder in mplayer, not to mention the video plays near perfectly. Best $15 I've spent in a while

Hi

I went step by step through the tutorial, but the patch is not applied to the mplayer sources. Or better the patchprocess does not finish. How long does it normally take?

You may have missed a < in the patch command. This is easy to do with the way the wiki has been written. The patch should only take a few seconds to apply.

The command to patch mplayer is:
patch -p0 < "path-to-coreavc-for-linux"/mplayer/dshowserver.patch

Also, the dshowserver.patch doesn't install cleanly against the current mplayer svn source code (as of mplayer svn revision 27448). To get mplayer to call dshowever I had to apply the patch and then manually edit libmpcodecs/vd.c

vd.c needs &mpcodecs_vd_dshowserver, added as follows:

#ifdef CONFIG_OGGTHEORA
	&mpcodecs_vd_theora,
#endif
	&mpcodecs_vd_dshowserver,
#ifdef CONFIG_WIN32DLL
        &mpcodecs_vd_dshow,
        &mpcodecs_vd_dmo,

This is because the current mplayer svn has changed the call to CONFIG not USE. Once you add in this line you should be able to build mplayer so that playback starts.

@TabletGuy

big thx, worked fine

[Nullack]

No offence, but why do this? Your running windows binaries through an emulator slowing it all down when there is existing AVC and H.264 decoders that are native and pretty fast.

I have compiled optimised SVN builds of ffmpeg and mplayer. That decodes H264 well including PAFF, Gstreamer as well with Totem will do it without much of a difference in performance.

I had a go at CoreAVC/compiling Mplayer and didn't finish it easily.

Are there any hints for improving h264/x264 performance without going through ugly compilation?

I'm currently reading through this 1080p HD content: terrible performance thread for ideas

[gladstone]

Thought I'd bring something else up: I copied the HD vid in question (Elephants Dream) to my external drive (SATA II going thru USB, can't remember any of the other specs) and it played absolutely fine with none of the stutters it had while on my internal laptop drive...

I guess I should be testing my I/O speed.

I too have followed this guide on hardy 64 bit, and dshowserver passes the test, mplayer seems to find and load the codec just fine, but when playing a movie, I also get a blank screen and mplayer hangs.
