それマグで!

知識はカップより、マグでゆっくり頂きます。 takuya_1stのブログ

習慣に早くから配慮した者は、 おそらく人生の実りも大きい。

recpt1 でhttpオプションを有効にする.

recpt1のオプションで --http と言うモノを見つけたので取り込んだ.

recpt1がそのままHTTP接続を受け付ける.
VLCからHTTPでアクセスするだけ。
VLCからチャンネル指定できる.
Bon_DriverのHTTPとも組み合わせられる.

httpつけると

VLCなどでHTTPのアドレス+ファイル名(チャンネル)を指定すれば、PT2から直接ストリームが降ってきて便利。

コードとか

使い方

ちょっと古いのでパッチを作って置いた

あがってるrecpt1のベースのコードがちょっと古いので最新版の差分パッチをあてて差分作っておいた.
