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
