Delphi - JNIエラー - 優秀な図書館

私は、TCameraComponentからイメージを取得し、TIdUDPServerを使用して別のデバイスに送信するアンドロイド向けのDelphi 10 Seattleでアプリケーションを開発しています。私は、TIdUDPServerを処理するためのスレッドを作成し、画像やその他のテキストコマンドを送信しました。これは次のように動作します。メインスレッドは、スレッド内でビットマップの書き込みを行い、スレッドが送信します。Delphi - JNIエラー

問題は、致命的なシグナル6エラーのアプリケーションのクラッシュ、私はそれが同じオブジェクトにアクセスするスレッドに関連していると思う、私はオブジェクトを保護するためにTCriticalSectionを使ってみましたが、私はまだですエラーが発生しました。ここで

は、私は、モトEのAndroid 6.0を使用しているメインスレッド

procedure TFormMain.CameraComponent1SampleBufferReady(Sender: TObject; 
    const ATime: TMediaTime); 
var 
    Bitm: TBitmap; 
begin 
    try 
    Bitm:= TBitmap.Create; 
    CameraComponent1.SampleBufferToBitmap(Bitm, True); 
    BabyImag.Bitmap.Assign(Bitm); 
    Log.d('DBBaby', nil, 'Image on Screen');

あなたは十分に十分にあなたのスレッドのFBitmapオブジェクトを保護されていません。

スレッドがSetGetImage(nil, False)を呼び出すと、TCriticalSectionは、それがBitmSurfaceにAssign()「EDときFBitmapへのアクセスがロックされていないので、ロックされた後、SetGetImage()終了する前にアンロックされます。つまり、メインスレッドはFBitmapを変更できますが、BitmSurfaceは依然としてコピー中です。

がより代わりにこのような何か試してみてください：

procedure TFormMain.CameraComponent1SampleBufferReady(Sender: TObject; 
    const ATime: TMediaTime); 
begin 
    CameraComponent1.SampleBufferToBitmap(BabyImag.Bitmap, True); 
    Log.d('DBBaby', nil, 'Image on Screen'); 
    if SendVideo then 
    FCommThread.SetImage(BabyImag.Bitmap); 
end;

type 
    TComThread = class(TThread) 
    private 
    { Some code } 
    procedure GetImage(ASurface: TBitmapSurface); 
    protected 
    procedure Execute; override; 
    public 
    Constructor Create(UserType: Integer);
