めちゃんこうまい家庭菜園のジャガバタ＼(^O^) ／

家庭菜園のキュウリと茄子のお漬物、粗塩とまろぽんやねん(^O^) ／

取れたてジャガイモをジャガバタでいただきます。＼(^O^) ／

やったよ、家庭菜園でジャガイモ大収穫や(^o^)丿

3月始め家庭菜園でジャガイモを植えたけど

収穫時期がよく分からず昨日まで放置プレイ状態だった

今日は天気が良いもんでいっきに収穫へ

でるわ、でるわジャガイモごろごろ

いやー、心配したけど大収穫やんか

pepoと

誰やねん！キュウリ盗んわ(- 人-)

せっかくキュウリ収穫出来るようになったのに、カラスか分からないけどこの有様やねん。(_´Д｀)ノ~~

ffmpegをgitからfree版を構築してみたよ(^o^)丿

http://dag.wieers.comのffmpegはどうもnofreeのパッケージなため自前でfree版のffmpegをgitから構築してみたよ

まずはgitでcloneを作成
[root@fedora15 src]# git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

でインストールできたffmpegのライセンスを表示させると
[root@~]# ffmpeg -L

ffmpegのライセンスについて注意！

[root@ ~]# wget http://dag.wieers.com/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

[root@ ~]# yum --enablerepo=rpmforge install -y ffmpeg

とffmpegをhttp://dag.wieers.comからインストールしてUSBカメラのキャプチャが出来た見たいだけれど

googleさま曰くffmpegのライセンスにはfree版とそうで無いものがあるようなのだ

http://dag.wieers.com/　からインストールしたものはnofreeのものがあり

PepoLinuxへffmpegをインストールしてみたよん

ここを参考にPepoLinuxへffmpegをインストールしてみた
[root@ ~]# wget http://dag.wieers.com/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

[root@ ~]# rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.i386.rpm

[root@ ~]# rm rpmforge-release-0.3.6-1.el5.rf.i386.rpm 

[root@ ~]# yum --enablerepo=rpmforge install -y ffmpeg

でもってUSBカメラを接続

[root@ ~]# tail /var/log/messages

ログからカメラを認識したところで画像をjpegモードでゲット

[root@ ~]# ffmpeg  -f video4linux2 -s 640x480 -i /dev/video0 -y test.jpeg

ちなみに

[root@ ~]# ffmpeg -t 5 -f video4linux2 -s 640x480 -i /dev/video0 -y test.mpeg

とやればmpegファイルも取得できる
