HOWTO: Compiling mplayer with multi-core decoding support

[disembowler]

Does this HWOTO work for all of guys on Januty or is there experiencing similar problems as I am, when using the libavcodec libavformat libavutil libs from ffmpeg-mt instead of the ones shipped with mplayer trunk?

If I am the only one having those troubles, then it might be something wrong on my end here...cuz I have basically just followed the HOWTO step-by-step and still getting these errors when compiling mplayer. I tried the previous and current svn revision of mplayer, but it fails on both

I appreciate any ideas...Thanks

I'm having the same problems as disembowler. Maybe there's something changed in ffmpeg-mt...

[mc4man]

I don't have any h.264/good enough hardware to test so can't see if there are any issues. (mplayer build works fine for what I do use for

MPlayer SVN-r29241

If you also replace the libswscale folder in mplayer using the one from the 0.5 release then the build succeeds
(( 'replace' meant merge. not rm & cp
(again may be unintended consequences, could be narrowed down to a file(s) and or line(s)

(interesting that there is nothing in the libswscale folder in ffmpeg-mt source

Nope, still doesn't work for me.

Step-by-step description of what I did:
1. Get the current SVN version of mplayer (r 29241), ffmpeg, ffmpeg-mt

svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
git clone git://gitorious.org/ffmpeg/ffmpeg-mt.git

2. Replace the folders in the mplayer directory with the ones from ffmpeg-mt

cd mplayer
rm -rf libavcodec libavformat libavutil
cp -a ../ffmpeg-mt/libavcodec .
cp -a ../ffmpeg-mt/libavformat .
cp -a ../ffmpeg-mt/libavutil .

3. Use the libswscale stuff from ffmpeg sources and "merge" it into my mplayer/libswscale folder

cd ..
cp -fr ffmpeg/libswscale/* mplayer/libswscale/

4. Configure and Make mplayer

cd mplayer
./configure --codecsdir=/usr/lib/codecs --confdir=/etc/mplayer --enable-gui --prefix=/usr
make

make produces the same error.

@mc4man: Is this what you did as well and where it worked for you???

The funny thing is though that it works if I do not replace the three libav* folders with the stuff from ffmpeg-mt (step 2). So I don't actually think it' just related to libswscale but (also) to something else.

Fresh ideas are welcome ...

[BarryBooze]

mc4man's solution worked fine for me.
Try the libswscale folder from the 0.5 ffmpege release, not from current SVN ffmpeg.

[mc4man]

@disembowler
I didn't see the errors, warnings you show

svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg

..........using the one from the 0.5 release

(link in orig. post

If you know ffmpeg's code well I'm sure it could be patched, if not then some time spent could point to the differences.

As a start a merge worked, noting I can't test other than normal (for me) use of mplayer in which I've noticed no ill effects

For the moment I'd assumme BarryBooze is using the patched mplayer for what it's meant for and seems ok with it

thanks, it realy work for me. after copy folder from version 0.5 to mplayer/libswscale all configured and maked correctly.

Alright! After using the libswscale libraries from the 0.5 ffmpeg release I got it working! Many thanks for helping me out here!
Well ... I thought because 0.5 was just released March 10, there probably weren't many changes to the libswscale libs and I could just use them ... which was obvisouly wrong.


It might be good to update the initial post as well to reflect the necessity of having to update the libswscale sources, too.

Nevermind, I omitted --enable-live when ./configuring and then it compiled.

I get the following and then it stops.

Any ideas? mplayer vanilla compiles properly, but pulling ffmpeg-mt and copying those directories to the mplayer directory breaks things.

I also get the libswscale thing, but fetching the 0.5 tarball and copying its files into the svn mplayer's libswscale subdirectory made it compile properly.

[white_hat]

Hi all!
I've just compiled latest mplayer with multi-threaded h.264 support. It's easier then in this guide, just:

1. $ sudo apt-get install build-essential checkinstall subversion git-core libgpac-dev yasm
2. $sudo apt-get build-dep mplayer mencoder
3. $ git clone git://repo.or.cz/mplayer && cd mplayer && git checkout origin/mt && git submodule init && git submodule update && ./configure && make && sudo make install

That's all! Now 1080 movies can be smoothly played on my 1.3Ghz c2d without dropped frames
