Androidの画像シーケンスから動画を作成するには、javacv 0.6ライブラリを使用しましたが、問題が発生しました： 通常、htc Sensation（Android 4.0.1、プロセッサタイプarmv7）とhtc Desire （アンドロイド2.3.3、プロセッサタイプARM7）携帯電話は、それはHTC Wildfireの上では動作しません （アンドロイド2.3.5、プロセッサのタイプARMv6のは）電話は特にそれがコード内画像のシーケンスから動画を作成するjavacv

も例外ではありません。
1.私はそれを修正できますか？
2.私は、問題がデバイスのプロセッサタイプに接続されているバージョンを持っています。
もし私が正しいのですが、どうすれば解決できますか？
ありがとうございます。
