rtmpdump_nicolive

なにこれ

rtmpdump（librtmp）にニコニコ生放送用のnlplaynoticeを実装したパッチを当てたやつです

入れ方

作業環境：ubuntu14.10

$ git clone https://github.com/meronpan3419/rtmpdump_nicolive.git $ cd rtmpdump_nicolive $ make $ make install Makefileのprefix弄ってないとlibrtmpを/libにcpするので適当にするかsudo make installで

/libにlibrtmp入れた時にパス通ってないことあるので、通しておく。

$ export LD_LIBRARY_PATH=/lib

ubuntuの場合アレなので、 /etc/X11/Xsession.optionsのuse-ssh-agentをno-use-ssh-agentにしてログインし直すとexportできるかも。

how to use

http://watch.live.nicovideo.jp/api/getplayerstatus?v=lv******** から

$ rtmpdump -o out.flv -vr "[getplayerstatus/rtmp/url]/[getplayerstatus/stream/id]" -C S:"[getplayerstatus/rtmp/ticket]" -N "[getplayerstatus/stream/contents_list/contentsのrtmp://から始まる文字列]"

$ rtmpdump -o out.flv -vr "rtmp://nleu12.live.nicovideo.jp:1935/liveedge/live_150425_22_1/lv218887875" -C S:"155149:lv218887875:4:1429968658:686df8fd057d0825" -N "rtmp://nlpoca104.live.nicovideo.jp:1935/publicorigin/150425_22_1/,lv218887875?1429968658:30:5c5ce9d9d515fb0a" -p "http://live.nicovideo.jp/watch/lv218887875"

###ファイルに保存する場合 $ rtmpdump ほにゃにゃら -o out.flv ###vlcで見る場合 $ rtmpdump ほにゃらら -o - | vlc -
