CoreAVC codec's current status (fixme please)

Hi,

I would like to know how much of MPlayer users' interest CoreAVC issue 
generates.

For me it was breathtaking to finally see something being done in 
MPlayer in regard to having CoreAVC DirectShow filter working. Sadly, it 
was almost a year ago and since then there's been no further work done 
by the developers.

Current status is as follows:

If you're lucky enough to have a HD x264 avi  movie, you're golden - 
works flawlessly:

Opening video decoder: [dshow] DirectShow video codecs
Decoder supports the following YUV formats: YUY2 IYUV YV12 I420
Decoder is capable of YUV output (flags 0x27)
VDec: vo config request - 1440 x 900 (preferred colorspace: Packed YUY2)
[PP] Using codec's postprocessing, max q = 4.
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.60:1 - prescaling to correct movie aspect.
VO: [directx] 1440x900 => 1440x900 Planar YV12
VideoDecoder::SetExtAttr: registry failure
Selected video codec: [coreavc] vfm: dshow (CoreAVC DShow H264 decoder 
for x86 - http://corecodec.org/)

Unfortunatelly, most (all?) of the HD x264 encoded material is 
distributed in Matroska container, and that gives a sad:

I have been always of opinion that getting content is more of a
problem than getting it to play, one way or another :p

Have you tried the above?

Lol :P

The CoreAVC is not available in the package, it's just a default 
suggestion when a codec fails.

MPlayer wasn't able to use fancy DirectShow filter decoders. A set of 
CoreAVC specific patches provided by Alan Nisota partly did the trick 
and I was simply wondering if there is a chance to err push things a bit :)

Interestingly, I somehow missed the whole discussion about lavdopts 
fast=1 and skiploopfilter=all, perhaps it would be enough to play my 
movies with libavcodec... will try to do that as soon as I get back home :)

I often watch 720p and 1080p H.264 movies with mplayer using CoreAVC.

I don't have this problem. I use the following patch :

I use CoreAVC under Windows (mplayer compiled with MinGW). I don't know
about Linux.

> what CPU are u useing? and the byte rate of the 1080p H.264?

I have a Core 2 Duo E6600. I watch pure HDTV 1080i H.264 videos from TS
files (meaning : they haven't been transcoded). Bitrate is approx. 18
mbit/s. When playing these videos with CoreAVC mplayer consumes 60-70%
of the CPU (which means the second core is used).

I also play some 720p H.264 files in MKV containers which have been
transcoded from 1080i videos. The bitrate of these videos is approx. 3
mbit/s. I can play them without CoreAVC (one core is sufficiant for
libavcodec).

I think the problem is not just the fact that the audio is 5.1: All
the 5.1 soundtracks of my DVDs do decode correctly.

Definitely not :) This file does not have 5.1 audio, its 2 channel AC3. I
think error messages are just misleading...
