[gentoo-dev] mplayer with dvdread ..

[gentoo-dev] mplayer with dvdread ..

[Henti Smith]

hi all 

I been battling to get mplayer with dvd working and I went throught the mplayer dvd docs.
libdvdread is included in the tarball and can be used but I see there is also a media-libs/libdvdread-0.9.4

mplayer has advd option but it only uses the media-libs/libdvdnav library .. and in the docs it says this

DVD Navigation support (dvdnav)
                                                                                                                  
   Support for DVD navigation via dvdnav was being worked on, but it was never finished properly and it is
   currently unmaintained. Who knows, it might even compile.

   MPlayer uses libdvdread and libdvdcss for DVD decryption and playback. These two libraries are contained
   in the libmpdvdkit2/ subdirectory of the MPlayer source tree, you do not have to install them
   separately. We opted for this solution because we had to fix a libdvdread bug and apply a patch which
   adds cracked CSS keys caching support to libdvdcss. This results in a large speed increase because the
   keys do not have to be cracked every time before playing.

   MPlayer can also use system-wide libdvdread and libdvdcss libraries, but this solution is not
   recommended, as it can result in bugs, library incompatibilities and slower speed.

Using this info I patched mplayer to use the internal libdvdread and libdvdcss libraries and it work wonderfully.

Would it be recommended to alter the ebuild for mplayer to use the internal libraries .. maby changing the lib names to reflect mplayer use only and patching mplayer for that then sticking with the current non working solution ?

Afiak, if you have 'dvd' in USE, it enables --enable-mpdvdkit, which
DOES use the libdvdread and libdvdcss included with mplayer.  This is
shown here as from ebuild:

----------------------------------------------------------------------
  use dvd \
      && myconf="${myconf} --enable-mpdvdkit --enable-dvdnav" \
      || myconf="${myconf} --disable-mpdvdkit --disable-dvdread \
                           --disable-css --disable-dvdnav"
----------------------------------------------------------------------

We may just disable the dvdnav support if that is wat breaks things for
you ...

I thought so as well ... but if you go throught the documentation in mplayer 
and you have dvd specified .. it will use libdvdread and libdvdcss if its installed on your machine

and the ebuild does not have libdvdread or libdvdcss in the RDEPEND settings .. so if you run a stock box and USE="dvd" 
and emerge mplayer you only get dvd-nav which does not work.

> We may just disable the dvdnav support if that is wat breaks things for

dvd support works fine ... but it's not enabled .. 

to get mplayer to emerge with dvd support correctly you have to emerge libdvdread and libdvdcss manually .. 
and then USE="dvd" and emerge mplayer.

As I pointed out in the original mail this is not recommended by the mplayer developers anyway and they suggest you use the internal libdvdread and libdvdcss libs they supply.

I'm more then happy to create a new ebuild with correct patching to make this work (I hacked a ebuild to get everything working on my system) 
hence the suggestion to change the mplayer spacific libs to libmplaydvdread and libmplaydvdcss instead of the defaultsa so you can use both libs without 
cuaseing problems.

I really do think think this is a good thing to have fixed as alot of guy I know are looking at mplayer for DVD playback and would not knwo that they need to 
have libdvdread and libdvdcss installed before emerging mplayer

Having 'dvd' specified in USE will have no effect if the ebuild do not
tweak ./configure time options.  But I think I do not fully understand
what you are getting at here ...

No, look at that bit I pasted.  It add the '--enable-mpdvdkit' flag,
which enables the internal libdvdread and libdvdcss.  It works fine
over here ... I have watched many encrypted movies this way.

Like I said .. it is over here.  This is bits from when I run
'emerge mplayer':

-------------------------------------------------------
Checking for DVD support (libmpdvdkit) ... yes
Checking for DVD support (libcss - old style) ... no
Checking for DVD support (libdvdread - new style) ... disabled by
libmpdvdkit2
Checking for DVD support (libdvdnav) ... yes
-------------------------------------------------------

See ... libmpdvdkit (internal libs) gets enabled. ...

-------------------------------------------------------

-------------------------------------------------------

Once again mpdvdkit2 gets enabled, but yes, dvdread and dvdcss does
get disabled, but this is because mpdvdkit2 is these two libraries
with bug fixes and the 'dvd key caching'.

This is when i run 'mplayer -dvd 1', but lack of dvd title at hand
right now ...

I did notice this ... 

I'll play around and make double sure .. but on the machine I was working on .. it didn't do that.Thats why I was poking around in the 
mplayer docs and it's syas you have to set the DVDKIT_SHARED var to yes or it will not compile even if you specify it in configure .. 
I'll work on that machine again tonight and make 100% sure

Where does the ebuild link the deps for dvdread .. I cannot find it anywhere in the DEPEND or RDEPEND settings ? 
on the machine I was working on .. running emerge mplayer with USE="dvd" did NOT install libdvdread or libdvdcss.

As mentioned before mplayer does have libdvdread and libdvdcss included in the source and can be installed using mplayer, and it's recommended
as well is it might have patches etc etc for mplayer not in the main tree fot those libs.

Why does it list libdvdread and libdvdcss as dependancy's for mplayer if it uses the internal libs ? 

I'll have to check the original machine I worked on, because it didn't do that .. I had to hack the ebuild and patch the mplayer 
source to get internal libdvdread and libdvdcss to work

This did not happen on the machine .. at all .. even with dvd in USE settings .. all I had was dvdnav.
the only way I could get this to happen was to hack the configure script as directed in the docs by changing DVDKITSHARED=no to yes in configure script

I understand this ... ok .. I think we saying the same thing .. but in different ways that we don't understand .. 

I'll play around with this alot more .. as I think there are some quirks .. I just added USE="dvd" on my machine at the office and ran emerge mplayer -p and 
libdvdread libdvdcss and libdvdnav is now added as deps ... as in additional packages it needs to install to get dvd working ..

I understand :) 

> It definitely have libdvdread/css support ...

the machine I was working on has it as well ;P

Like I said in my previous mail, its the dvdnav DEPEND.  I removed it
in mplayer-0.90, since it does not work anyhow

Right, and that is what we use.  Check what the '--enable-mpdvdkit'
./configure option does ...
