Today, I have read the blog of Praveen (http://www.j4v4m4n.in/2010/05/26/webm-support-for-fedora-13/) about how he added support for webm in Fedora13 (for ffmpeg). Though I heard about Google releasing VP8 codec as Free Software, I never thought of downloading a .webm file( What’s the use of it , if you can’t play it 
). However, after downloading the ‘bigbrotherstate.webm” file from Praveen’s blog, I have tried to play it in my favorite media player, ‘mplayer’ and failed.

———————–
It’s all very well having latest o2 Mobile Broadband or a computer with a lightning fast processor, if your mplayer doesn’t work, none of that is quite as good. This is how I fixed my problem:
Then I started my night long effort by tinkering with the mplayer source and VP8 patches and finally made it working in Ubuntu Linux.
Mplayer playing the “bigbrotherstate.webm”
webm in mplayer
I have created a log file for this activity: Here it goes:
As per the project (http://www.webmproject.org/code/build-prerequisites/), the VP8 Codec SDK (libvpx) has build dependency on Yasm assember for optimized building on x86 (32 and 64 bit).
At first, get the Yasm assembler from (http://www.tortall.net/projects/yasm/wiki/Download)
wget http://www.tortall.net/projects/yasm/releases/yasm-1.0.1.tar.gz
tar zxvf yasm-1.0.1.tar.gz
cd yasm-1.0.1
./configure
make
sudo make install
Now, go for the libvpx and build it.We can download the libvpx source from webm project page:http://code.google.com/p/webm/
wget http://code.google.com/p/webm/downloads/detail?name=libvpx-0.9.0.tar.bz2
tar jxvf libvpx-0.9.0.tar.bz2
cd libvpx-0.9.0
./configure
make
sudo make install
There comes the mammoth task of downloading the patches for adding webm support to mplayer :mplayer-vp8-encdec-support-r1.tar.bz2
wget http://code.google.com/p/webm/downloads/detail?name=mplayer-vp8-encdec-support-r2.tar.bz2
tar jxvf mplayer-vp8-encdec-support-r1.tar.bz2

Now Compile mplayer:
./configure –enable-libvpx-vp8-lavc
make
Finally… after 5 hours of fight with the includer files and Makefiles and modifying some files (sorry.. in half sleep), I got .webm support working with mplayer…
Now, my newly built mplayer can play .webm files.. Yooo.. hoooo…
Thanks to Praveen for inspiration and .webm file.
Finally, see mplayer in action.
./mplayer /home/maxin/Downloads/bigbrotherstate.webm
Hoping to submit the modified patches after re-creating the patches against the latest mplayer source code from SVN. I will be pushing the modified source code to my blog-site.
Update: The modified tar file is available under the following URL:

ffmpeg with webm compiled in DEB package
http://www.megaupload.com/?d=YTSYPOE2
Hello, Is is possible to share the source code of mplayer as tar file ? I am trying to apply the patches to the latest mplayer sourec code and its not working. Also I understand that mplayer latest code already has webm integarted but could not compile it.
