mplayer_codecs_basic

[peebee]

The mplayer_codecs_basic .pet comes from puppy-noarch-official repository and doesn't seem to have been updated since 2007!

2 of the codes require libstdc++.so.5 whereas modern puppies have .6

so the package needs recompiling - but where does the source come from???

Code: Select all

# cd /usr/lib/codecs
# ldd cook.so       
	linux-gate.so.1 (0xb77da000)
	libstdc++.so.5 => not found
	libc.so.6 => /lib/libc.so.6 (0xb7627000)
	/lib/ld-linux.so.2 (0x80050000)
# ldd drvc.so       
	linux-gate.so.1 (0xb77e7000)
	libstdc++.so.5 => not found
	libc.so.6 => /lib/libc.so.6 (0xb75f4000)
	/lib/ld-linux.so.2 (0x800f7000)
# 

or would links work to satisfy the missing dependencies?

what do these codecs do anyway? Presumably nobody had detected that they don't work in modern pups - otherwise they would have been updated?

Hi peebee.

The codecs read the various media formats. There's probably a thousand of these formats
nowadays.

I have compiled from source the recent mplayer 1.2.1 for my "Pooch" a few weeks
ago but I haven't shared it yet. I wanted to test it first. It's got all the codecs within
itself, from the looks of it. Compiled on eglibc 2.13.
-- https://mplayerhq.hu/design7/news.html--

I didn't discriminate (pre-select) any of them when I compiled it, so it'll take whatever
media format you throw at it. Works fine with gnome-mplayer.

Interested? Just say the word! I've added it to the Pooch thread already.

15 Mg's zipped, 38 Mg's un-zipped. List of files below. Because of its size, I decided to
have it reside in /mnt/home, with proper symlinks to within the Pup.

BFN.

P.S.
I know someone else on this forum did a compilation of this 1.2.1 version recently,
and offered it as a sfs, I think. It's what prompted me to do mine, actually, because his
didn't work in my "Pooch", IIRC. I can't find it at the moment with the forum search
function, but I know it's there somewhere.

Hi Musher0

I know what codecs in general do....I was wondering what cook and drvc in particular do?

I'm trying to squish a few remaining missing dependencies in my LxPupSc build so I really just want up-to-date versions of cook.so and drvc.so

Thanks for your interest and help
Cheers

Hello peebee,

Looking in Wheezy and Slacko 5.7 there are both versions of libstdc++ (.5 and .6) in /usr/lib but I guess in later Pups the .5 may have been left out so adding it back in may be one solution.

I think the codecs are from a rather old Real Player package. I see them in an old Real Player for Linux. The MPlayer website makes it clear that they are now rather obscure and unlikely to be needed. Real media has become abandoned by most users and it may be that support for it is now included via ffmpeg anyway and the default config has this statically linked into mplayer. The website does not appear to offer those codecs as source, only binary libs. The Real code was never open source as far as I know.

[peebee]

Thanks @OscarTalks

I think adding 900KB to the build just for these obscure codecs would probably be OTT.

I'll probably leave the codecs in the build but include a link from .6 to .5 but have no way to test if this is sensible - can't be any worse than the current situation though.

@OscarTalks is right

cook is an old realaudio codec
drvc is an old realvideo codec

@peebee

As far as I know MPlayer contains the cook and drvc codecs by default.
mplayer_codecs_basic package is a relict of the time when codecs and MPlayer were separate packages.
But this is a long time ago.
I uninstalled mplayer_codecs_basic for a test in Slacko 6.3.0 and checked this under use of default installed MPlayer version 1.1-4.8.2.

Code: Select all

#mplayer -ac help | grep cook

You see, both codecs are still existing.

Btw.
Of course it's useful to use a separately directory for codecs which MPlayer do not contain by default.
But do not forget to configure MPlayer with --codecsdir=DIR before compiling.
