Can't get the coreavc trial version to work.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. build dshowserver (Btw: the wiki instructions are incorrect, should be
just make and not make -c ..)
2. registered, changed registry path to HKLM\Software\CoreCodec\CoreAVC Trial
3. ran test, outputs (after turning on registry TRACE) : 

$ ./dshowserver -c CoreAVCDecoder.ax -s 1280x720 -g
09571a4b-f1fe-4c60-9760de6d310c7c31 -b 12 -f 0x34363248 -o 0x30323449

Using CoreAVC trial 1.7.0

same codec and serial works correctly inside windows in virtualbox.

any idea?

I looking into it a little, and the problem is with 
static struct reg_value* find_value_by_name(const char* name)
it does not find the key and return 0.

I added some debug info:
 static struct reg_value* find_value_by_name(const char* name)
 {
+       TRACE("find_value_by_name %s, reg_size = %d\n",name, reg_size);
        int i;
        for(i=0; i<reg_size; i++)
+       {
+               TRACE("Compating %s to %s, res = %d\n", name, regs[i].name,
strcmp(regs[i].name, name));
                if(!strcmp(regs[i].name, name))
                        return regs+i;
+       }
        return 0;
 }

and I don't understand why it every worked.
this is what I get:
find_value_by_name HKLM\Software\CoreCodec\CoreAVC Trial\Serial, reg_size = 2
Compating HKLM\Software\CoreCodec\CoreAVC Trial\Serial to HKLM, res = -92
Compating HKLM\Software\CoreCodec\CoreAVC Trial\Serial to HKCU, res = -9

Are you sure this is how you expect it to work? I am not surprised it's not 
working.

okay, looks like the real problem was that it opened a different registry file
(registry32).
you might want to add a trace of the actual registry file opened to hint users 
that
have this problem.

Thanks.
you can close this ticket.

User resolved issue.  I will look into writing a log message with the path to 
the
registry to ease debug

Great.
btw:
there are some inaccuracies in the wiki,

In DshowserverInstall:
make -C dshowserver

should be just make.

in RegisterCoreAVC:
If you are using mplayer or xine do:
export REGISTRY=$HOME/.mplayer/registry

to me it was registry32 for mythtv (latest from svn).

You might want to mention that to try with the latest coreavc trial you need to 
put
the serial number in the registry path:
HKLM\Software\CoreCodec\CoreAVC Trial\Serial

There was also a instruction to copy registercodec after applying the mplayer 
patch,
- which was duplicate (wrong path) and duplicate anyway - but I can't find it - 
maybe
you have already fixed it.

speaking of inaccuracies :):

should be:
to me it was registry32 for MPLAYER (latest from svn).

I have this problem too, but if there's a solution in this thread it's not 
clear to
me what that is.

Something about registry32?

Here is my output:

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

Failed to create DirectShow filter
Failed to open win32 codec CoreAVCDecoder.ax

with regedit I see my serial under 
HKEY_LOCAL_MACHINE\Software\CoreCodec\CoreAVC Trial

What else do I need to do?
