ffmpeg

Using ffmpeg , Server-Side convert

■ffmpegを使用して Server-Side Flash_Video 生成環境を作ることを目的とする。

=== 事前準備 ===
DAGリポジトリの導入http://dag.wieers.com/rpm/FAQ.php#B2
アーキテクチャを確認してインストールする。下記は、CentOS5i386の場合

rpm -Uhv http://apt.sw.be/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

DAGリポジトリを通常無効にしておく（OS標準のリポジトリとの整合性に問題が出ることがあるので）

sed -i 's/enabled = 1/enabled = 0/g' /etc/yum.repos.d/rpmforge.repo

ffmpegインストール

本体と、リビルド環境、開発環境を導入

yum install --enablerepo=rpmforge ffmpeg
yum install rpm-build gcc

AMRのインストール

■3gpからflvへの変換を行うためオーディオコーデックを導入
■ファイル置き場を作成し、移動する。

mkdir /usr/local/src/ffmpeg
cd /usr/local/src/ffmpeg

■tarファイルからrpmを作成

wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-7.0.0.0.tar.bz2
rpmbuild -ta amrnb-7.0.0.0.tar.bz2

wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-7.0.0.2.tar.bz2
rpmbuild -ta amrwb-7.0.0.2.tar.bz2

一気にinstall

rpm -Uvh /usr/src/redhat/RPMS/i386/amr*.rpm

ソースの取得とffmpeg.specの設定

SourceRPMを取得し、コンパイル

wget http://dag.wieers.com/rpm/packages/ffmpeg/ffmpeg-0.4.9-0.9.20070530.rf.src.rpm

展開

rpm -iiv ffmpeg-0.4.9-0.9.20070530.rf.src.rpm

■151行目の行末をescapeし、下記を追記（変更行は次の通り）

vi /usr/src/redhat/SPECS/ffmpeg.spec

--disable-strip \
--enable-libamr-nb \
--enable-libamr-wb

rpmbuild
rpmbuild -ba /usr/src/redhat/SPECS/ffmpeg.spec

★大量の依存関係のエラーが出るため、依存関係を解消するため、パッケージをインストールする。

yum install SDL-devel freetype-devel zlib-devel libogg-devel libvorbis-devel libtheora-devel texi2html

yum install --enablerepo=rpmforge imlib2-devel lame-devel faad2-devel faac-devel gsm-devel xvidcore-devel x264-devel a52dec-devel

■リビルド開始

rpmbuild -ba /usr/src/redhat/SPECS/ffmpeg.spec

★P4-1GHzマシンでは、15分程度の時間がかかります。

■出来上がったpackageをinstall

rpm -Uvh /usr/src/redhat/RPMS/i386/ffmpeg-*.rpm

■ffmpeg -versionコマンドを発行

Supported file protocols:
file: http: pipe: rtp: tcp: udp:
Frame size, frame rate abbreviations:
ntsc pal qntsc qpal sntsc spal film ntsc-film sqcif qcif cif 4cif
Motion estimation methods:
zero(fastest) full(slowest) log phods epzs(default) x1 hex umh iter

Note, the names of encoders and decoders dont always match, so there are
several cases where the above table shows encoder only or decoder only entries even though both encoding and decoding are supported for example, the h263 decoder corresponds to the h263 and h263p encoders, for file formats its even worse
