Adobe Airを使用してRTSP経由でビデオを再生しようとしていますが、次の権限があります。
<action>access_internet</action>
<action>set_audio_volume</action>
<action>access_shared</action>
<action>play_audio</action>
しかし、私が（）をプレイすると、何もしません。
PlaybookでRTSPストリーミングを実行することは可能ですか？そうでない場合は、他の種類のビデオストリーミングが可能ですか？webworks？html5ビデオタグ？
ネイティブのYoutubeアプリは、ストリーミングビデオを事前にインストールします。
前もって感謝します
ここにサンプルコード
