coreavc in mplayer, vlc, xmbc...

[lar1r]

By not being open source, does this preclude CoreAVC from ever making it into MPlayer?

More to the point - any chance we'll see this on the Xbox in programs like XBMC? Would be incredible to push that 733Mhz CPU for AVC playback.

Thx - great decoder

CoreAVC could work through the MPlayer Win32 and DirectShow loaders. I already tried if it would work directly, but it seems to require some additional changes in the Win32 support layer. I'm not familiar with that code myself, so unfortunately I can't help much right now. Send a request to the MPlayer users mailing list with all the information they need: http://www.mplayerhq.hu/DOCS/HTML/en/codecs.html#codec-importing.

Is there any plan for having a linux mplayer / vlc plugin build ?

[multicone]

When will there be a Linux plugin for VLC ?

[videomixer9]

let me make a wild guess, never, it would even violate policies of VLC as they only accept GPLed software even for plugins or at least required things to be OSS iirc

Huh? I thought I understood everything so far until I saw these two posts.. How does this pertain to CoreAVC and what in the world is a Linux plugin? Isn't Linux an Operating System? How you should make a plugin for that contained an OS for a multimedia player - and why?

Maybe I missed something... please explain :confused: .

Agreed. Until M$ gets its OS act together (Vista?) on this issue, it seems wise that decoders provide their users the option of software colorspace conversion. The default could be none, thus incurring no speed penalty.

You should send them this as a suggestion if you really want it implemented ;) . I sent them a lengthy suggestion and explanation telling them I want a widget functionality in the sidebar in longhorn and look what happened - they implemented it.
Just go to the MS website and try to contact them - they have a form for that stuff. I'm guessing this would save Picard alot of time of coding, but I guess it's too late now anyway.

P.S. Betaboy, didn't you say version .72 would be released last Sat. or is that this Saturday? I'm confused - been checking the page very many times...

[BetaBoy]

GK... yeah it was supposed to be... but with the things ppl asked picard to so... its a lil late ;-)

Well I hope that someone will be working on this. I would be satisfied if the Xbox could at least play H264 in 720x576 without frame drops. That should be possible with CoreAVC.

Have you try tu put the dll file from CoreAVC into codec directory of XBMC and to modify the codec.conf for enabling this filter ?!

( VP7 for exemple work with this method ... ;) )

[LoRd_MuldeR]

If added this to codecs.conf:

videocodec coreavc
info "CoreAVC H.264 Decoder"
status working
fourcc H264,h264
fourcc X264,x264
fourcc avc1
fourcc davc,DAVC
format 0x10000005
driver dshow
dll "CoreAVCDecoder.ax"
;guid 0x80040111
out YV12 ;,I420,IYUV
out YUY2,UYVY


But I get this error:

Opening video decoder: [dshow] DirectShow video codecs
ERROR: Could not open required DirectShow codec CoreAVCDecoder.ax.
Warning: DS_Filter() no such class object. (DLL=CoreAVCDecoder.ax, r=0x80040111)

You need to upgrade/install the binary codecs package.
Go to http://www.mplayerhq.hu/dload.html
VDecoder init failed :(
Cannot find codec matching selected -vo and video format 0x34363268.
Read DOCS/HTML/en/codecs.html!


Any ideas ???

[Seb.26]

Oh ... problem ...

Try a look at :

( I haven't read the full post, but it's look like the embedeb library for mkv cannot demux mp4 ... )

The developers of MPlayer will never implement support for a closed source CoreAVC DLL when there is an open sourced alternative (libFAAD), ...even if that open sourced alternative doesn't preform as well. I think the same goes probably for XINE and VLC as well. They will rather take the time to improve the existing open sourced alternative or create a new open source one than support a closed source version.

You can ask them yourself via their dev mailing-list if you feel like getting flamed :p

Not tested personally...

[LoRd_MuldeR]

Interesting.

Maybe it can be added to the codec package one day :)

[OddbOd77]

Did anyone already post/test this (http://mythtv.org/pipermail/mythtv-dev/2006-April/047052.html) mplayer patch? The author claims it uses some voodoo but it's the best lead I have seen so far.

[eLupus]

not working yet. i've tried to get it working in xbmc, but currently stumbling on an access violation that i haven't been able to track down. hopeless to debug external codecs, the printf way wich is kinda the only option we have.

it loads fine, but breaks on first picture that is decoded.
