Boa noite, tenho um Ideapad 330 i5 com webcam integrada Easycamera e não consigo sair da tela preta por nada. No skype, kamoso, cheese e VLC a luz acende mas sem nenhuma imagem Já cheguei até em forums da frança e nada do que tentei funcionou. Se alguém souber eu mando um sorvete de ifood uahuahuah. Segue o necessário (acho) uname -sr Linux 5.9.0-1-amd64 dmesg | grep uvcvideo [ 26.818012] uvcvideo: Found UVC 1.00 device EasyCamera (174f:241a) [ 26.826718] uvcvideo 1-8:1.0: Entity type for entity Extension 3 was not initialized!

Olá! Estou fazendo um projeto em que a webcam padrão tira fotos a cada 1 segundo utilizando o opencv. Por enquanto ,nesse code, ao clique do botão capturar você seleciona a pasta onde quer e ele captura uma foto.Preciso, alem do loop para ele tirar fotos a cada segundo, salva-las em um determinada pasta. public class jfmPrincipal extends javax.swing.JFrame { VideoCaptura webCam; ExibeQuadro exibeQuadro; Thread executor; private DaemonThread myThread = null; int count = 0; VideoCapture webSource = null; Mat frame = new Mat(); MatOfByte mem = new MatOfByte(); class DaemonThread implements Runnable { protected volatile boolean runnable = false; @Override public void run() { synchronized(this) { while(runnable) { if(webSource.grab()) { try { webSource.retrieve(frame); Highgui.imencode(".bmp", frame, mem); Image im = ImageIO.read(new ByteArrayInputStream(mem.toArray())); BufferedImage buff = (BufferedImage) im; Graphics g=jlbCaptura.getGraphics(); if (g.drawImage(buff, 0, 0, getWidth(), getHeight() -150 , 0, 0, buff.getWidth(), buff.getHeight(), null)) if(runnable == false) { System.out.println("Going to wait()"); this.wait(); } } catch(Exception ex) { System.out.println("Error"); } } } } } } private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { int returnVal = jFileChooser1.showSaveDialog(this); if (returnVal == JFileChooser.APPROVE_OPTION) { File file = jFileChooser1.getSelectedFile(); Highgui.imwrite(file.getPath(), frame); } else { System.out.println("Acesso negado."); } }

Boa tarde. Estou utilizando o componente DelphiTwain para captura de imagem através de webcam. Quando chamo o evento para capturar a imagem, ele abre uma tela do próprio windows e faz quantas capturas você quiser. O problema é que essas imagens capturadas não são gravadas em nenhum outro lugar, a não ser no dispositivo de imagem (webcam). Elas ficam armazenadas no dispositivo como Imagem 001, Imagem 002, e assim por diante. Gostaria de saber se há um jeito de já gravar com um nome e em um caminho escolhido por mim. Ou então se tem algo no Delphi que copie essas imagens do dispositivo para uma outra pasta. Obrigado.

Boa tarde, pessoal. Tudo bem?! Estou precisando de uma grande ajuda para utilizar mais de uma webcam. Preciso de algo que liste as webcams instaladas ou alguma outra forma que eu possa escolher qual webcam utilizar. Já vi inúmeros tópicos relativos a webcam, mas nada que me ajudasse neste caso. O programa está fazendo a captura de imagem da seguinte forma: var frmCapturaImg: TfrmCapturaImg; hWndC: THandle = 0; rg: string; implementation uses U_frmCadMoradores; {$R *.dfm} const WM_CAP_START = WM_USER; const WM_CAP_STOP = WM_CAP_START + 68; const WM_CAP_DRIVER_CONNECT = WM_CAP_START + 10; const WM_CAP_DRIVER_DISCONNECT = WM_CAP_START + 11; const WM_CAP_SAVEDIB = WM_CAP_START + 25; const WM_CAP_GRAB_FRAME = WM_CAP_START + 60; const WM_CAP_SEQUENCE = WM_CAP_START + 62; const WM_CAP_FILE_SET_CAPTURE_FILEA = WM_CAP_START + 20; const WM_CAP_SEQUENCE_NOFILE =WM_CAP_START+ 63; const WM_CAP_SET_OVERLAY =WM_CAP_START+ 51 ; const WM_CAP_SET_PREVIEW =WM_CAP_START+ 50; const WM_CAP_SET_CALLBACK_VIDEOSTREAM = WM_CAP_START +6; const WM_CAP_SET_CALLBACK_ERROR=WM_CAP_START +2; const WM_CAP_SET_CALLBACK_STATUSA= WM_CAP_START +3; const WM_CAP_SET_CALLBACK_FRAME= WM_CAP_START +5; const WM_CAP_SET_SCALE=WM_CAP_START+ 53 ; const WM_CAP_SET_PREVIEWRATE=WM_CAP_START+ 52; function capCreateCaptureWindowA(lpszWindowName : PCHAR; dwStyle : longint; x : integer; y : integer;nWidth : integer;nHeight : integer;ParentWin : HWND; nId : integer): HWND; STDCALL; EXTERNAL 'AVICAP32.DLL'; ///// === CONECTA WEBCAM === ///// if hWndC <> 0 then exit; hWndC := capCreateCaptureWindowA('WINACESSO',WS_CHILD or WS_VISIBLE ,image1.Left,image1.Top,image1.width,image1.height,frmCapturaImg.Handle,0); if hWndC <> 0 then begin SendMessage(hWndC, WM_CAP_SET_CALLBACK_VIDEOSTREAM, 0, 0); SendMessage(hWndC, WM_CAP_SET_CALLBACK_ERROR, 0, 0); SendMessage(hWndC, WM_CAP_SET_CALLBACK_STATUSA, 0, 0); SendMessage(hWndC, WM_CAP_DRIVER_CONNECT, 0, 0); SendMessage(hWndC, WM_CAP_SET_SCALE, 1, 0); SendMessage(hWndC, WM_CAP_SET_PREVIEWRATE, 66, 0); SendMessage(hWndC, WM_CAP_SET_OVERLAY, 1, 0); SendMessage(hWndC, WM_CAP_SET_PREVIEW, 1, 0); end; ///// === CAPTURA IMAGEM === ///// rg := frmCadMoradores.txtCadMoradores_RG.Text; if hWndC <> 0 then begin SendMessage(hWndC,WM_CAP_SAVEDIB,0,longint(pchar('C:\WINACESSO\FOTOS\' + rg + '.bmp'))); end; ///// === DESCONECTA WEBCAM === ///// if hWndC <> 0 then begin SendMessage(hWndC, WM_CAP_DRIVER_DISCONNECT, 0, 0); hWndC := 0; end;

Pessoal estou com o seguinte problema eu preciso fazer um aplicativo que mostre 4 webcams USB. E também capturar a imagem da webcam e salvar em determinado diretorio. Obrigado.
