[MPlayer-dev-eng] DXR3/H+ plugins for MPlayer pre-beta release, need feedback!

[David Holm]

Hi,
here are the plugins we have all been waiting for, dxr3/hollywood+ 
support for MPlayer.
This is the pre-beta release (I need some feedback) which currently 
plays mpeg-(1/2) hardware accelerated and divx (or any other codec 
support YV12 output) non-hw accelerated.

There are lots of notes to take into account here to get it working as 
it should and I hope I won't miss any of them:
1. edit your codecs.conf file and make sure that videocodec mpegpes is 
listed before videocodec mpeg12, otherwise mpeg-(1/2) will be decoded in 
software and not hardware
2. to be able to play YV12 formats (including divx) you must have ffmpeg 
(http://ffmpeg.sourceforge.net/) installed as a shared library (download 
ffmpeg and run ./configure --enable-shared) and _NOT_ as 
mplayer/libavcodec, I think libavcodec has been broken because it 
doesn't work with -vo mpegpes either... so remember NO libavcodec, BUT 
libffmpeg.so!! otherwise no divx. Another thing, divx playback seems to 
default to msmpeg4 or something like that, so you might (most probably) 
have to add "-vc odivx" since that one supports YV12 output, read 
through the codecs.conf any videocodec that has out YV12 will work
3. tv-out only so far
4. I need benchmarks, and I don't mean numbers, tell me your computer 
setup and if divx's (primarily) is running at an acceptable speed or 
whatever (it's possible to edit the quality of the output to speed up 
software codec's, but I'm waiting for MPlayer (and especially the gui) 
to come up with a working config-system, hey, when are we going to be 
able to use the plugin configure buttons in the gui?!
5. "-vo dxr3" will use the dxr3 for video output and use your default 
audio output option for audio, there is however a "-ao dxr3", but I have 
no idea how well this is working, if at all (haven't had the opportunity 
to test it), so please send me tons of feedback on that, if it doesn't 
work just use "-ao oss" or whatever until I fix it...
6. both patches are against current cvs versions (2001-11-01) of both 
mplayer and em8300. you will need both patches to successfully compile 
mplayer.

I'm currently working on adding support for more codec outputs, so don't 
worry if movie type X doesn't play yet (let me know though so I can add 
support for that codec faster)

Message to every developer out there, I would do ANYTHING for an actual 
working realmedia codec, there is an sdk located here: 
http://proforma.real.com/rnforms/resources/server/realsystemsdk/index.html 
which will enable someone to actually do this (you will also need to 
have the latest realplayer installed since it's using closed source 
lib's from there) Please, please, PLEASE someone take this project 
on..... (postprocessing of realvideo would be great....)

Note to em8300 cvs maintainer and mplayer cvs maintainer:

There is no need to add the mplayer patch to cvs unless you really want 
to, as I said, this is a pre-beta, I have no way of successfully testing 
the drivers at home since there is something fucked up with my video 
output... need feedback to make sure everything is perfect. also, 
mplayer developers, give me a working gui-configure interface 
(libvo->query_options() etc) there are lots and lots of interesting 
options to be added... especially for those with slower computers... 
another thing, unlock that lame, avi, asf, mov, mpg playing restriction, 
it's supposed to be a media player, I wan't to play my mp3's ogg's wma's 
etc too!!

em8300 maintainer, pretty please add my patch to the cvs =)... those two 
features are very useful when playing audio, keep up the good work.
