ffmpeg(ライブカメラ用サーバー)の設定
############################################################################
●ffmpeg （ライブカメラ用サーバー）の設定
（１）準備（USBカメラを用意する）
カメラ：
UVC対応 WEBカメラ
（２）FFMPEGのインストール
公式サイト： http://www.ffmpeg.org/
■パッケージでインストールする場合
(ffmpeg と ffserver がアボートする)
1) パッケージでインストールする場合はリポジトリを追加する
「サードパーティーのリポジトリを追加」を参照
2) FFMPEGをインストールする
[root@localhost ~]# yum -y install ffmpeg
3) ffserver の設定ファイル(ffserver.conf)の雛形が無いので作成する
ffserverを起動するとアボートしましたとメッセージが出て終了してしまう。
ソースコードからインストールした方が良さそうです。
■ソースコードからインストールする場合
1) ソースコードをダウンロードする。
リポジトリから最新のソースを取得するか、リリース版のtarballを取得する
1-1)リポジトリからソースをダウンロードする場合
git が入っていなければ、インストールする
[root@localhost ~]# yum -y install git
リポジトリからソースをダウンロードする
[root@localhost ~]# cd /usr/local/src
[root@localhost src]# git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
1-2)リリース版の tarball を使う場合
taballをダウンロードする
[root@localhost ~]# cd /usr/local/src
[root@localhost src]# wget http://www.ffmpeg.org/releases/ffmpeg-2.0.1.tar.gz
ダウンロードした tarballを展開する
[root@localhost src]# tar zxvf ffmpeg-2.0.1.tar.gz
2) ダウンロードしたディレクトリに移動して、INSTALL というファイルを読む
[root@localhost src]# cd ffmpeg-2.0.1
3) INSTALL の記述通りにビルド＆インストールする
[root@localhost ffmpeg]# ./configure
yasm not found, use --disable-yasm for a crippled build
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
上記のようなメッセージが出るので --disable-yasm をつけて再度実行
[root@www ffmpeg-2.0.1]# ./configure --disable-yasm
