処理スケッチにウェブカメラのフィードがあり、ビデオを録画して保存できます。私が達成したいのは、私が次のケース(drawScreenOne)に行ったときに、今録画したビデオがキャンバスに表示されるということです。私が今問題を抱えているのは、com.hamoidのビデオ書き出しライブラリを使ってビデオを保存すると、スケッチと同じフォルダに保存されますが、動画を再生するにはデータフォルダに保存する必要があります。だから私はそれを手動でデータフォルダに移動せずに映画を再生することはできません。処理の中からそれを行うことはできますか? これまでに作成したばかりのビデオは、どのように読み込むことができますか?私はそれのための配列を使用する必要がありますか?私は手動でデータフォルダに移動するときに私は映画を再生することができますが、私はそれを処理する処理したい。処理 - 処理スケッチでビデオを録画して表示する
