Requested video codec family [coreserver] (vfm=dshowserver) not available. #27

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
I have used a recent mplayer svn checkout and used http://svn.mplayerhq.hu/
mplayer/branches/1.0rc2/etc/codecs.conf?revision=24724&view=markup this 
codecs.conf and added http://code.google.com/p/coreavc-for-linux/wiki/
MplayerInstallation as instructed here. I get Requested video codec family 
[coreserver] (vfm=dshowserver) not available. Enable it at compilation. No 
change with an RC2 tarball.

My dshowserver installation worked fine.

Note: I used videocodec coreserver:

videocodec coreserver
  info "CoreAVC DShow H264 decoder 1.7 for x86 - http://corecodec.org/"
  status working
  ;format 0x10000005
  fourcc H264,h264 H264
  fourcc X264,x264
  fourcc avc1,AVC1 AVC1
  fourcc davc,DAVC
  fourcc VSSH
  driver dshowserver
  dll "CoreAVCDecoder.ax"
  guid 0x09571a4b, 0xf1fe, 0x4c60, 0x97, 0x60, 0xde, 0x6d, 0x31, 0x0c, 0x7c, 0x31
  out YV12,IYUV,I420,YUY2

If I do not comment out the format, I also get Cannot find codec matching 
selected -
vo and video format 0x31637661.

Erm, sorry i get that regardless of what i do with format. Adding  format 
0x31637661 
results in " Cannot find codec matching selected -vo and video format 
0x31637661."

what command line are you using?

you definitely don't want 'format 0x31637661'

it looks like the dshowserver patch didn't get activated in mplayer correctly.
can you verify that:
ls libmpcodecs/vd_dshowserver.*
shows:
libmpcodecs/vd_dshowserver.c  libmpcodecs/vd_dshowserver.o
libmpcodecs/vd_dshowserver.d

Also:
grep -a2 mpcodecs_vd_dshowserver libmpcodecs/vd.c
sould give:
extern vd_functions_t mpcodecs_vd_theora;
extern vd_functions_t mpcodecs_vd_dshow;
extern vd_functions_t mpcodecs_vd_dshowserver;
extern vd_functions_t mpcodecs_vd_dmo;
extern vd_functions_t mpcodecs_vd_vfw;
--
        &mpcodecs_vd_theora,
#endif
        &mpcodecs_vd_dshowserver,
#ifdef USE_WIN32DLL
        &mpcodecs_vd_dshow,

If all that looks ok, then (and I hate to ask this) are you sure you are 
running the
mplayer that you built?

The answer to the last question is no. After typing which mplayer I saw 
/usr/local/
bin/mplayer so it did not occur to me that i need to type 
/usr/local/bin/mplayer . 
So this is solved and after installing a few more packages, now I even have the 
xv 
driver compiled and I have AVC running! Thanks much. (Though I get no audio, 
but I 
guess eventually I will find out the necessary option for that too)

I have the exact same problem; however, when I type in 

grep -a2 mpcodecs_vd_dshowserver libmpcodecs/vd.c

I don't see this chunk of code:

&mpcodecs_vd_theora,
#endif
        &mpcodecs_vd_dshowserver,
#ifdef USE_WIN32DLL
        &mpcodecs_vd_dshow,

Any idea what's going on?

I tried applying the patch again and this is the output I'm getting...

Seems like the patch isn't working anymore =(.

Same problem here with latest SVN. Which version is actually compatible?

latest release fixes the patch problem

I am having this problem now. The strange thing is that it usually works and I
haven't recompiled mplayer in the meantime. So I'm not sure what has broken it. 
I get
the message:

==========================================================================
Forced video codec: coreserver
Cannot find codec matching selected -vo and video format 0x31637661.

i am actually still getting this problem and im not finding this block of code

#ifdef USE_WIN32DLL
        &mpcodecs_vd_dshow,

in fact i only see CONFIG_WIN32DLL, never USE_
i am using the latest svn of both mplayer and coreavc-for-linux

also, my output is a little bit different

Forced video codec: coreserve
Requested video codec family [coreserve] (vfm=dshowserver) not available.
Enable it at compilation.
Cannot find codec matching selected -vo and video format 0x31637661.
Read DOCS/HTML/en/codecs.html!

i did patch mplayer however, and my dshowserver tests fine
although it does have an extra line the install guide didnt have

dshowserver -c CoreAVCDecoder.ax -s 1280x720 -g 
09571a4b-f1fe-4c60-9760de6d310c7c31

sorry to triple post but i solved the problem for me by deleting the
~/.mplayer/codecs.conf file and copying a brand new one from the mplayer 
source, then
adding the relevant codec info from the install guide.
