HowTo: Install the very latest MPlayer under Jaunty Jackalope

What on earth is, or are, electricsheep?

It's actually kinda interesting idea, remembered ck.ing out last year

Hi Nullack,

cd ~/src/mplayer
svn checkout svn://svn.ffmpeg.org/soc/wmapro wmapro
cp wmapro/wma* libavcodec
patch -p0 <wmapro/audioframesize.patch
patch -p0 <wmapro/mplayer.patch
patch -p0 <wmapro/wmapro_ffmpeg.patch

It has taken a little prodding on these forums and a pointer from the MPlayer-users but I have finally taken your advice and installed the wmapro work from SOC. You of course were right: it works brilliantly!

Only slight modification I made is copying the files a little differently:

cp -v wmapro/wma3dec.c wmapro/wma3data.h wmapro/wma3.h libavcodec

It is a minor niggle but copying as 'wm*' also copies wmapro_ffmpeg.patch, this makes no difference but I am a little anal at times .

Playing a demo file now gives:

Exiting... (End of file)

I am not sure if this belongs in the Jaunty guide but I might consider adding it in this weekend as I am rewriting some sections based on advice from Carl Eugene you may have seen in MPlayer-users. Exciting times indeed for MPlayer .

The one thing I've noticed (and others have confirmed ) is that at times lately (last couple of weeks) the current svn of ffmpeg, when used with the current svn of wmapro will result in 3 possibilities
1. it succeeds
2 it fails with numerous wma3dec.c (wma3dec.o) errors (then adding bitstream.h to libavcodec allows build to succeed
3. it fails with a simple error and won't compile "libavcodec/wma3dec.c:315: error: too many arguments to function ‘ff_mdct_init’"

right now ffmpeg revision 18839 and wmapro -r 4283 will build perfectly ( whether in mplayer or ffmpeg itself
and also the latest -r 18892

( I do a quick ck. using wmapro's checkout.sh to see if it will build

Hi mc4man,

right now ffmpeg revision 18839 and wmapro -r 4283 will build perfectly

Sounds a little 'bleeding edge' for this guide perhaps . I guess the question is when will ffwmapro join FFmpeg proper?

[Nullack]

IMHO ffmpeg should hurry up and merge the wmapro decoder code. Its been ages and most of the SVN changes are fluff rather than core changes.

[mc4man]

Sounds a little 'bleeding edge' for this guide perhaps

Maybe so, though it's almost always worked for me

The wmapro -r's (going back a little ways, seem to be the same, it's just 'some' ffmpeg -r's have an issue

The one that caused an issue the other day for someone was ffmpeg -r 18875, tonights -r 18892 works fine.

(the quick test only takes a few minutes or so, doesn't seem suitable for a guide though

Edit: the bitstream.h thing was resolved apparently some -r's back, so the patch should work virtually all the time

< #include "bitstream.h"
---
> #include "get_bits.h"

the hang up would be an errant ffmpeg -r and it seems that mplayer always uses the latest ffmpeg svn when you checkout an mplayer svn. (good thing or not ...?

Edit: it's sorta a viable alternate dual install, a patched ffmpeg and patched mplayer, getting the wwmapro, mplayer sources at the same time.
If a .checkout.sh, configure and make works for ffmpeg, then it will work for mplayer, if not then it won't.

The easiest immediate solution would be to replace (replace, not merge,) the 5 ffmpeg dir.'s in mplayer with those from an earlier ffmpeg -r, most likely just a couple back. (I say that's the 'sorta' part

Hi mc4man,

it seems that mplayer always uses the latest ffmpeg svn when you checkout an mplayer svn. (good thing or not ...?

I think it is often a cautious thing to avoid updating MPlayer immediately after a sync with the FFmpeg libraries .

Hi pen,

Thank you for a very good tutorial!

It is my pleasure, I am glad it all worked out for you .

Thank you for this guide! It was very useful, I'm glad someone linked it to me because I'd wasted hours trying to get mplayer to work when I hadn't installed all that stuff previously. Great guide with plenty of detail but perfectly clear.
