GStreamerをWindows向け(MSVC)かつIntel MEDIA SDK対応でビルドする

#はじめに
※手っ取り早く利用する場合はWindows版のバイナリ版が配布されています。
https://gstreamer.freedesktop.org/data/pkg/windows/

GStremerをWindows向けにビルドする手順を現時点(2019年4月)のものをまとめました。
この記事の内容も将来には古くなって参照するべきでないものになるかもしれないので注意。

以下の条件でのGStreamerビルドを行います。

 + Windows10 上でWindowsネイティブのGStreamerをビルド
 + Intel MEDIA SDKの利用
 + Visual C++ Runtimeの使用
 + ビルド環境とターゲット環境は同一

ビルド後の対応機能(プラグイン)については[gst-inspectの結果](#gst-inspectの結果)を参照してください。
バイナリ配布されているものとほぼ同様の品ぞろえのようです。H.264,H.265,VP8,VP9 などのコーディックにも対応しています。

GitLabの公式リポジトリ上のReadme.mdの内容にそっています。作業したうえでの注意点について(日本語環境特有の問題など)についてフォローしています。

GStreamer/cerbero のGitLabページ:
https://gitlab.freedesktop.org/gstreamer/cerbero

GStreamerの公式ページにもビルド方法の記述があるが、現時点(2019年4月)では情報が古いの注意。
https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-cerbero.html

#準備

公式サイトの通りに必要なモジュールをインストールします。
[Installing Minimum Requirements on Windows](https://gitlab.freedesktop.org/gstreamer/cerbero#installing-minimum-requirements-on-windows)

また、Intel MediaSDKを利用したいのでこれもインストールします。ダウンロードにはユーザー登録が必要です。
https://software.intel.com/en-us/media-sdk/choose-download/client

インストールが必要なツールは以下の通りです。インストール済みの場合でもバージョンには注意してくさい。

+ Python 3.6 以降
+ Git
+ MSYS/MinGW
+ Visual Studio 2015以降
+ CMake
+ WiX 3.11.1
+ Intel MEDIA SDK
+ yasm

## Python 
https://www.python.org/downloads/

公式サイトでは **Python 3.5 or newer** となっていますが、Windowsの日本語環境ではデフォルト文字コードの取り扱いに変更があったので **Phthon 3.6以降** を利用するようにしてください。
参考: [Python 3の各種エンコーディングについて#Windows](https://qiita.com/methane/items/6e294ef5a1fad4afa843#windows)

Anacondaでインストールしたpythonでもビルド可能です。

## Git
https://gitforwindows.org/
公式サイトに、**Checkout as-is, commit as-is** でインストールせよという指示があります。
これはコミット時の改行コードの変換設定になり、デフォルト設定のCRFL-LF 変換を行う設定から、行わない設定に変更することになります。

既にインストール済みで、異なる設定でgitを利用している場合は、GStreamerをビルドしたいときだけ変更した方が無難です。

また、SoruceTreeがこの設定をデフォルトに再設定する場合があるようです。ビルド中はSourceTreeは実行しない方が良いでしょう。

## MSYS/MinGW
https://sourceforge.net/projects/mingw/

公式の説明通りにインストールしてください。

[Install MSYS/MinGW](https://gitlab.freedesktop.org/gstreamer/cerbero#install-msysmingw)

GStreamerはMSYS2環境でのビルドは保証していません。
> MSYS is not the same as MSYS2, and the
GStreamer project does not support running Cerbero inside the MSYS2
environment. Things may work or they may break, and you get to keep the pieces.

## Visual Studio
https://visualstudio.microsoft.com/vs/older-downloads/

~~Visual Studio 2015 以降が必要とありますが、リリースされたばかりのVS2019は避けた方が無難でしょう。~~
**Visual Studio 2019でも問題なくビルドできます。**
インストール時に「C++によるデスクトップ開発」のチェックが入っていれば （たぶん）大丈夫です。

最新のWindows10 SDKをインストールが必要ですが、デフォルトでチェックされているはずです。
公式サイトでのインストーラーのチェックイメージを引用します。
>![VS2017インストーラーチェックイメージ](https://gitlab.freedesktop.org/gstreamer/cerbero/raw/master/data/images/vs2017-installer-workloads.png)

## CMake
https://cmake.org/download/
特に問題なければ最新版をインストールしてください。PATHへの登録はお好みで。

## WiX 3.11.1
https://github.com/wixtoolset/wix3/releases/tag/wix3111rtm
ページの下の方、wix311.exe をダウンロードして実行してください。

## Intel MEDIA SDK
https://software.intel.com/en-us/media-sdk/choose-download/client
ユーザー登録が必要です。

## yasm
自動的にツールチェインに追加されるはずなんですが、私の環境で1.16.2をビルドした際に必要となりました。
yasmが見つからないとエラーが出た場合は以下の方法で導入してください。

http://yasm.tortall.net/Download.html
**Win64.exe** のリンクから **yasm-1.3.0-win64.exe** をダウンロードします。
上記のexeを **yasm.exe** とリネームして MinGWのbinフォルダ(`C:\MinGW\bin`)へコピーしてください。

# ビルド

GStremerのビルドを行います。**すべて完了するまで6時間程度かかります** 。

もし、SourceTreeを利用している場合は、この作業の間はSourceTreeを実行しないでください。SourceTreeがGitのデフォルト設定を変更する場合があるようです。

MSYSのコマンドプロンプトを開きます。

まずはインストールしたプログラムが利用可能か確認します。

---
Intel MediaSDKの環境変数が正しく設定されているか確認します。

**INTELMEDIASDKROOT** が正しく設定されていればOKです。
設定されていない場合は再起動の必要があるか、インストールに失敗しています。

```shell
$ set | grep INTELMEDIASDKROOT
INTELMEDIASDKROOT='C:\Program Files (x86)\IntelSWTools\Intel(R) Media SDK 2018 R2\Software Development Kit\'
```
---
Gitの設定を確認します。

```shell
$ git config --global core.autocrlf
false
```

**false** と表示されればOKです。**false** 以外の場合は設定を変更します。

```shell
git config --global core.autocrlf false
```
---
CMakeが実行できるか確認します。

```shell
$ cmake --version
cmake version 3.14.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).
```
エラーとなる場合はPATHが通っていないので、PATHへ追加します。C:\CMake へインストールした場合は以下のように設定します。

```shell
PATH=$PATH:/C/CMake/bin
export PATH
```

Gstremer/cerbero をcloneします。

```shell
git clone https://gitlab.freedesktop.org/gstreamer/cerbero
```

cloneしたceberoディレクトリへカレントを移動します。

```shell
cd cerbero
```

bootstrapを実行します。完了するまで **2時間程度かかります** 。

```shell
./cerbero-uninstalled bootstrap
```

さて、これからようやく本番です。GStreamerのパッケージをビルドします。
Visual Studio と Intel MEDIA SDK を利用する Optional Features を指定してビルドします。
完了するまで **4時間程度かかります** 。

```
./cerbero-uninstalled -v visualstudio -v intelmsdk package gstreamer-1.0
```

オフィスでやる場合は終業前に実行して一晩放置がおすすめです。

#確認

ビルドが完了すると、**build\dist\msvc_x86_64** にビルド済みファイルが作成されます。

**build\dist\msvc_x86_64\bin** フォルダでコマンドプロンプトを開いて動作確認します。

```shell
./gst-launch-1.0.exe videotestsrc ! autovideosink
```

テストパターンが表示できれば成功です。
