[MPlayer-users] 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:

Opening video decoder: [dshow] DirectShow video codecs
Warning: DS_Filter() could not connect to output pin. 
(DLL=CoreAVCDecoder.ax, r=0x8004022a)
Failed to create DirectShow filter
ERROR: Could not open required DirectShow codec CoreAVCDecoder.ax.
You need to upgrade/install the binary codecs package.
Go to http://www.mplayerhq.hu/dload.html
VDecoder init failed :(
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)

Is anyone even remotly interested in playing 1080p HD content or is it 
just me? ;P

Furthermore, should I simply nag the developer behind the original 
MPlayer-CoreAVC patches or is there a more polite way to signal an issue?

Regards,

Andrew
