これはすでに1ヶ月間ですが、今は希望を失っています。Android - カメラから別のAndroidデバイスにビデオをストリーム
私は、デバイス1からビデオをキャプチャし、デバイス2
にそれをストリーミングしようとしています私はすでにビデオファイルを保存することができますが、装置1が取得している間、私は同時に別の電話にそれをストリーミングするときに問題がありますビデオカメラを使用しています。
私はストリーミングビデオに関する多くのチュートリアルを見てきましたが、私のビデオに適用されていますが、ビデオはすでにキャプチャされずにストリーミングされています。
私はあなたにこれを手伝っていただければ幸いです。
。
更新............................................. ...................
現在、私はソケット経由でテキストを送信できます。私はちょうど私の電話のデータを保存するテストするためにそこにイメージのキャプチャを含んでいますが、それはまだソケットを介して送信していません。
これが今の私の現在のコードです：

私はそれをしようとします。 私は別の電話でソケットとレンダリングのテキストを使用しようとしました。それは正常に動作しますが、それは他のデバイスにビデオを転送する媒体としてそれを使用することは可能ですか？ また、提供されたコードで質問を更新しました。このコンセプトをストリーミングビデオに使用するだけで可能かどうか考えていますか？ –
