If you have a codec not listed here, and not supported yet, just read section 2.1.4 to get info about how to help us adding support for it!
This section contains information about the DivX4 codec of ProjectMayo. Their first available alpha version was the OpenDivX 4.0 alpha 47 and 48. Support for this was/is included in MPlayer, and built by default. We used to use its postprocessing code to optionally enhance visual quality of MPEG1/2 movies. Now we use our own.
The new generation of this codec can even decode movies made with the infamous DivX codec! And it's not everything, it's MUCH faster than the traditional Win32 DivX DLL's. See below for configuration. The only disadvantage of this codec is that it's currently closed-source. :(
The codec can be downloaded from the following URL:
http://download2.projectmayo.com/dnload/divx4linux/divx4linux-20010718.zip
No automatic installing available at this time, so install it manually, EXACTLY as described here. Unpack it, and copy files to their place:
cp libdivxdecore.so.0.0.0 /usr/local/lib/
ln -s /usr/local/lib/libdivxdecore.so.0.0.0 /usr/local/lib/libdivxdecore.so.0
ln -s /usr/local/lib/libdivxdecore.so.0 /usr/local/lib/libdivxdecore.so
ldconfig
cp decore.h /usr/local/include/
Note: do NOT forget to add /usr/local/lib to your /etc/ld.so.conf !
MPlayer autodetects if DivX4 is (properly) installed, just compile as usual. If it doesn't detect it, you didn't install it exactly as above, and/or has fucked up config (see last question of 5.1 section).
Using it is a bit tricky. As it conflicts with the old OpenDivX (it's API is very similar to OpenDivX's), OpenDivX code is disabled, and the OpenDivX driver calls this library too.
Generally we can pinpoint this issue to that you have two options to use this codec:
| -vc odivx | using divx4 codec as a new version of OpenDivX. in this case it produces YV12 image in its own buffer, and MPlayer (libvo) does colorspace conversion. (RECOMMENDED!) | ||
| -vc divx4 | using divx4 codec's colorspace conversion. in this mode, you can use YUY2/UYVY too. |
The 'odivx' method is usually faster, due to the fact that it transfers image data in YV12 (planar YUV 4:2:0) format, thus requiring much less bandwidth on the bus. For packed YUV modes (YUY2, UYVY) use the 'divx4' method. For RGB modes you can choose freely, their speed is same, maybe differ according to the current bpp.
Note: it supports postprocessing too, but range of values is strange: (TODO UPDATE)
| 0 | no postproc | ||
| 10 .. 20 | postprocessing, normal (like level 2 with divxds) | ||
| 30 .. 60 | hard prostprocessing, eats many CPU (like level 4 with divxds | ||
2.1.2.2. ffmpeg's DivX/libavcodec
Beginning with version 0.4.2 , ffmpeg contains an opensource DivX codec, which is compatible with the traditional DivX. MPlayer supports this codec, and this makes it possible to watch DivX movies on non-x86 platforms! It was removed from MPlayer's cvs tree, you have to download it manually directly from FFmpeg's tree:
cvs -d:pserver:anonymous@cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg login
cvs -d:pserver:anonymous@cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg co ffmpeg
Note: if you copy with CVS subdirs, next time it's enough to do 'cvs update'.
Now, move the newly downloaded ffmpeg source's libavcodec directory, (with all it's subdirectories) to MPlayer's tree, so it will look like this:
main/libavcodec
Symlinking is NOT enough, you have to copy/move it!!!
./configure detects if it can be built. The codec also supports postprocessing!
In order to use it, refresh your codecs.conf file, and do as the manpage, or the example.conf says (the -vfm option).
Note: libavcodec contains other codecs as well (for example ffmpeg12), but at the moment we mostly focus on ffdivx, and it's unlikely that this will change.
2.1.2.3. Hardware AC3 decoding
You'll need an AC3 capable soundcard, with digital out (SP/DIF). The card's driver must support the AFMT_AC3 format (like SB Live! does). Connect your AC3 decoder to the SP/DIF output, and use the '-ac hwac3' option. It may or may not work (experimental). (probably won't...)
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://ftp.mplayerhq.hu/MPlayer/incoming/[codecname]/
DirectShow is the newer Video API, which is even worse than its predecessor. Things are harder with DirectShow, since
So let's search that goddamn registry..
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:
