Status of codecs support:
|
|
=========================
|
|
|
|
See http://mplayer.sourceforge.net/DOCS/codecs.html
|
|
|
|
If your codecs isn't listed there then help us adding support for it:
|
|
|
|
Extracting codecs from Win32
|
|
============================
|
|
|
|
1. VfW
|
|
~~~~~~
|
|
VfW (Video for Windows) is the old Video API for Windows. Its codecs have
|
|
the .DLL or (rarely) .DRV extension.
|
|
If MPlayer fails with your AVI:
|
|
|
|
UNKNOWN video codec: HFYU (0x55594648)
|
|
|
|
It means your AVI is encoded with a codec which has the HFYU fourcc (HFYU =
|
|
HuffYUV codec, DIV3 = DivX Low Motion, etc...). Now that we know this, we'll
|
|
have to find out which DLL Windows loads in order to play this file. In our
|
|
case, the system.ini contains this (with many others):
|
|
VIDC.HFYU=huffyuv.dll
|
|
So we'll need the huffyuv.dll file. Note that the audio codecs are specified
|
|
with the MSACM prefix :
|
|
msacm.l3acm=L3codeca.acm
|
|
This is the MP3 codec.
|
|
|
|
So, now we have all the info needed (fourcc, codec file, sample AVI), submit
|
|
your codec support request in mail, and upload these files to the FTP:
|
|
ftp://thot.banki.hu/MPlayer/incoming/<codecname>/
|
|
|
|
|
|
2. DirectShow
|
|
~~~~~~~~~~~~~
|
|
DirectShow is the newer Video API, which is even worse than its predecessor.
|
|
Things are harder with DirectShow, since
|
|
- system.ini doesn't contain the needed information, instead it's stored in
|
|
the registry :(
|
|
- we'll need the GUID of the codec.
|
|
|
|
So let's search that goddamn registry..
|
|
- Start 'regedit'
|
|
- press ctrl-f, disable the first two checkbox, and enable the third. Type
|
|
the fourcc of the codec. (for ex.: TM20)
|
|
- you should see a field which contains the path and filename
|
|
(for ex. : C:\WINDOWS\SYSTEM\TM20DEC.AX)
|
|
- now that we have the file, we'll need the GUID. Try searching again, but
|
|
now we'll search for the codec's name, not the fourcc. Its name can be acquired
|
|
when Media Player is playing that file, by checking File/Properties/Advanced.
|
|
If not, bad luck ;) Try guessing.
|
|
(for ex. search for : TrueMotion)
|
|
- if found (in registry), there should be a FriendlyName field, and a CLSID
|
|
field. Write down that 16 byte of CLSID, this is the GUID required by us.
|
|
|
|
NOTE : if searching fails, try to enable all the checkboxes.. you may have
|
|
false hits, but maybe you'll have the right, too...
|
|
NOTE : dump that M$ shit.
|
|
|
|
So, now we have all the info needed (fourcc, GUID, codec file, sample AVI),
|
|
submit your codec support request in mail, and upload these files to the FTP:
|
|
ftp://thot.banki.hu/MPlayer/incoming/<codecname>/
