radikoについてあれこれ

android radiko

プロトコルはrtmpなので、どうにかサーバ経由で、
Androidで聞けないかなあということであれこれ試してみる。

flvstreamerでファイルに保存

synapticで検索窓にrtmpと入力して検索すると、flvstreamerなるものがヒットする。
RTMP client と書いてあるのでとりあえずいれてコマンドを叩く。

$ flvstreamer 
FLVStreamer v1.8e
(c) 2009 Andrej Stepanchuk, The Flvstreamer Team, license: GPL
ERROR: You must specify a hostname (--host) or url (-r "rtmp://host[:port]/playpath") containing a hostname

どうやら

rtmp://host[:port]/playpath

というのがわかればきけるのか?
で、flvstreamerを使ったradiko保存方法をみると、以下でflvファイルに保存が簡単にでける。

flvstreamer -r "rtmp://radiko.smartstream.ne.jp:1935" -a "TBS/_defInst_" -y "simul-stream" -v -o TBS.flv

cronを使った定時録音の方法もありました。
flvに保存する一番簡単な方法。

rtmpdumpでコマンドラインでライブ視聴

シンプルにいける。

$ ./rtmpdump --rtmp "rtmp://radiko.smartstream.ne.jp:1935" --playpath "simul-stream" --app "TBS/_defInst_" --live | mplayer -

さらにシンプルに

$ ./rtmpdump -vr rtmp://radiko.smartstream.ne.jp/TBS/_defInst_/simul-stream | mplayer -

ローカルPCでrtmpgwで視聴

radikoをフラッシュ無しで再生を参考に,

rtmpgw起動、

$ ./rtmpgw --rtmp "rtmp://radiko.smartstream.ne.jp:1935" --playpath "simul-stream" --swfUrl "http://radiko.jp/player/player_0.0.9.swf" --pageUrl "http://radiko.jp/player/player.html#QRR" --app "QRR/_defInst_" --flashVer "LNX 10,0,45,2" --live --device 127.0.0.1 --sport 8088

と、なんかいろいろ吐くけど、まあ聴ける。
GNOME系のプレーヤでもアクセス先を合わせれば聴ける。

外部サーバ上でrtmpgwを動かして、ネット経由でアクセス

残念!!

どうやらサーバのIPが視聴可能でない。

視聴可能IPを持つサーバでrtmpgwにアクセスして視聴

AndroidのポッドキャストアプリListenでアクセス。
サーバはなんらかのレスポンスを受信してるっぽいが、
画面がプログレスのぐるぐるのまま。

中継ワンライナーがありました。
