[MPlayer-users] Windows binary proprietary codec

[Fernandon Bautista]

Dear all,

I have a windows binary proprietary codec that I need to load from Linux.
Following some examples that I have found on your list, I have done these
steps:

1) Edit etc/codecs.conf and add this entrance:

audiocodec g729b
info "Our provider g729b"
status working
format 0xXXX
driver acm
dll "g729b.acm"

2) Compile 32 bit mplayer:

export CC="gcc -m32"
./configure --enable-cross-compile --target=i686-linux
--prefix=/usr/local/bin --codecsdir=/usr/local/lib/codecs
make
make install


The output:

MPlayer SVN-r37401-snapshot-4.4.7 (C) 2000-2015 MPlayer Team

Playing colo.wav.
libavformat version 56.25.101 (internal)
Audio only file format detected.

MPlayer interrupted by signal 11 in module: init_audio_codec
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't
and
won't help unless you provide this information when reporting a possible
bug.

I understand that there is not implementation of the
InitializeSecurityDescriptor function. I took a look to the code and I
understood that you grabbed some Wine code to emulate/fake system calls . I
want to fix these and I was wondering if there is any doc or guidelines
for doing it.

Thanks in advance,

Fernando

I have a local hack I never finished that uses only
a 32 bit stub, in case that 32 bit MPlayer is an annoyance.
That stub can also be compiled as a Windows program to
be run via wine (actually that's the only way currently,
I haven't fixed it to support our loader).
It needs significant cleanup though, but if you might
consider going to that level of effort I can send it out.

We actually don't emulate any system calls to my knowledge, only library
calls.

Not really.
Your starting point would be loader/win32.c
For this function, exp_advapi32 array.
Then mostly try a copy-paste of an existing function like RegCloseKey
(just search for all occurrences of that string), most importantly
adjust the function signature to match the real thing
https://msdn.microsoft.com/en-us/library/windows/desktop/aa378863%28v=vs.85%29.aspx
and find out the least effort way to "implement" it that
makes the codec happy.
In that case I'd start by just returning 0 (i.e. error), and
hope they used the "just keep going when things go wrong"
strategy of error handling.
Alternatively and even simpler, hope they designed the codec
to work on win9x and use the UNDEFF macro instead.
Instead of providing a fake emulation, that one says "no,
that function does not exist", which would be like on
win9x.

Thanks for your answer! I will try to go for the second approach and if it
does not work, then I will ask you for this local version of mplayer for
running on wine.

Reimar,

I tried just by copy-paste of the RegCloseKey function. These are my files:

*etc/codecs.conf:*
audiocodec g729b
info "Our provider g729b"
status working
format 0x0135
driver acm
dll "g729b.acm"

*loader/win32.c:*
static const struct exports exp_advapi32[]={
FF(InitializeSecurityDescriptor, -1)
...
static WIN_BOOL
WINAPI expInitializeSecurityDescriptor(long security, int word)
{
WIN_BOOL result=InitializeSecurityDescriptor(security, word);
dbgprintf("InitializeSecurityDescriptor");
return result;
}

*loader/registry.c:*
WIN_BOOL __stdcall InitializeSecurityDescriptor(long security, int word)
{
return 0;
}

*loader/registry.h *
WIN_BOOL __stdcall InitializeSecurityDescriptor(long security, int word);


And this is what I am getting:

In there any way of getting more information? I have tried using gdb but I

I will install those packages and try again. In the meantime, if you could
suggest something, I would really appreciate.

Thanks.

Hi all again,

I am still trying to understand were the problem is. Along with this email
I have attached the output of the execution with -msglevel all=9. On the
other hand, by running gdb, I found out that the function acmStreamOpen
fails(which is called from from the function preinint that is defined on
libmpcodecs/ad_acm.c). Obviously there is not debug info on the codec so I
know that the codec calls to my InitializeSecurityDescriptor implementation
but that is all. Finally, I am thinking on using Wine
InitializeSecurityDescriptor implementation (this is what I found:
https://github.com/wine-mirror/wine/blob/dcc6868057605296a7dacd89211e0673396abe45/dlls/advapi32/security.c)
but it forces me to add more functions and by reading the functionality, I
am not sure that this is the problem.

I will really appreciate if you can give any new hint/suggestion.

Thanks in advance.

ACM_Decoder: Unappropriate audio format

Exiting... (End of file)
In there any way of getting more information? I have tried using gdb but
Program exited normally.
Missing separate debuginfos, use: debuginfo-install
glibc-2.12-1.149.el6_6.9.i686 zlib-1.2.3-29.el6.i686
I will install those packages and try again. In the meantime, if you
could suggest something, I would really appreciate.
Thanks.

Thanks for your answer! I will try to go for the second approach and if
it does not work, then I will ask you for this local version of mplayer for
running on wine.

I have a local hack I never finished that uses only
a 32 bit stub, in case that 32 bit MPlayer is an annoyance.
That stub can also be compiled as a Windows program to
be run via wine (actually that's the only way currently,
I haven't fixed it to support our loader).
It needs significant cleanup though, but if you might
consider going to that level of effort I can send it out.

Called unk_InitializeSecurityDescriptor
I understand that there is not implementation of the
InitializeSecurityDescriptor function. I took a look to the code and I
understood that you grabbed some Wine code to emulate/fake system

calls .
We actually don't emulate any system calls to my knowledge, only library
calls.

want to fix these and I was wondering if there is any doc or

guidelines

Post by Fernandon Bautista
for doing it.

Not really.
Your starting point would be loader/win32.c
For this function, exp_advapi32 array.
Then mostly try a copy-paste of an existing function like RegCloseKey
(just search for all occurrences of that string), most importantly
adjust the function signature to match the real thing
https://msdn.microsoft.com/en-us/library/windows/desktop/aa378863%28v=vs.85%29.aspx
and find out the least effort way to "implement" it that
makes the codec happy.
In that case I'd start by just returning 0 (i.e. error), and
hope they used the "just keep going when things go wrong"
strategy of error handling.
Alternatively and even simpler, hope they designed the codec
to work on win9x and use the UNDEFF macro instead.
Instead of providing a fake emulation, that one says "no,
that function does not exist", which would be like on
win9x.
