WebM VP8 Commissioning Environment Construction (i.)

There was a VP8, but the environment was completely different from H.

how to compile WebM VP8

Google compiling WebM

The WebM project is dedicated to developing a high-quality, and open video format for the web was freely available to Everyone.

Google put out this good thing, now to compile, actually very simple, because its readme said very detailed.

I compiled it with VS2005. Let's take a brief look at the process.

The source code for the download is: Http://code.google.com/p/webm/downloads/list in Vpx-vp8-debug-src-x86-win32mt-vs8-v0.9.0.zip

The details are: http://code.google.com/p/webm/downloads/detail?name=vpx-vp8-debug-src-x86-win32mt-vs8-v0.9.0.zip&can= 2&q=

1. Prerequisites

    * All x86 targets require the YASM[1] assembler is installed.
    * All Windows builds require this cygwin[2] be installed.
    * Building The documentation requires PHP[3] and doxygen[4]. If you does not
      has these packages, you must pass--disable-install-docs to the
       Configure script.

    [2]: http://www.cygwin.com/
    [3]: http://php.net/
    [4]:/HTTP/ www.doxygen.org/
   
2. Out-of-tree builds
out of tree builds is a supported method of building the application. For
an out of the tree build, the source tree was kept separate from the object
files produced during compilation. For instance:

$ mkdir Build
$ CD Build
$ .. /libvpx/configure <options>
$ make

Because I'm not going to compile the document, I've only done the 1th step [1], [2].

I went directly to http://www.tortall.net/projects/yasm to download the yasm, the name is Yasm-1.0.1-win32.exe, I later changed to Yasm.exe, and then put this to C:/Program files/ In Microsoft Visual Studio 8/vc/bin.

Also need yasm.rules, this is in the source code of Yasm, copied to C:/Program files/microsoft Visual Studio 8/vc/vcprojectdefaults directory.

[2] Then, I had already installed the Cygwin. You do not have to download, if this is not installed, you can go to download. Two methods, one is to download others do a good local file, another is their own online installation, online installation depends on your speed, need a waiting process.

[1]], [2] all are well and can be compiled.

Extract the code to C drive, file name is VP8

$ cd/cygdrive/c/
$ CD vp8/
$ ls
CHANGELOG README Bin build docs include Lib libvpx md5sums.txt src

$ CD build/

$ .. /src/configure--target=x86-win32-vs8--ENABLE-STATIC-MSVCRT--disable-install-docs

--disable-install-docs because I did not install the document, I added this parameter.

Just a moment to wait.

........................

You can generate Vpx.sln and other related files.

Then use your vs2005 to open the compilation.

As stated by the original author, I am from the website

[1]: Http://www.tortall.net/projects/yasm downloaded the Ysam, and according to the process he said to install.
About Cygwin, I got the ready-made installation files from someone else, much more convenient than downloading from the Internet.

Thank you, brother.

The specific Cygwin is installed in this http://blog.csdn.net/yarina/archive/2011/06/10/6536495.aspx.

However, the VP8 environment is much more difficult than imagined.
