Não é possível fazer o IAMStreamConfig.SetFormat () funcionar com o LifeCam Studio
Sou novato no DirectShow e estou trabalhando para adicionar um fluxo de vídeo ao meu aplicativo. Analisei muitas soluções por aí (TouchLess, DirectShow.net etc.) e acabei seguindo esserojeto pequeno no Code Project Não há muito, e é por isso que eu o selecionei; Eu queria trabalhar com uma pequena base de código, pois precisava implementar esse recurso rapidament
Depois de um dia sólido de leitura, experimentação e depuração, finalmente tenho tudo funcionando bem. Há um atraso que é uma chatice, mas posso me preocupar com isso mais tarde. O problema que tenho neste momento é quea câmera é capaz de 1280X720 e quero usar esta resolução. No entanto, parece determinado a capturar em 640x480. À medida que eu procurava cada vez mais e mais profundamente aprendendo como definir a resolução, finalmente pensei que tinha resolvido. Também encontrei o código nessa página do Project Code nos comentários que usei como bas
Após 6 horas de tentativa, não consigo fazer com que esta câmera altere sua resolução. Não estou recebendo nenhum erro e o HRESULT retornado de SetFormat () é 0, mas a câmera não altera a resolução.
Há muito código para colar tudo, mas eu gostaria de incluir a seção que cria o gráfico, pois imagino que seja esse o problem
Aqui está o código que configura o gráfico

[UPDATE] Adicionado o método ConfigureSampleGrabber () abaixo
HRESULT CameraMethods::ConfigureSampleGrabber(IBaseFilter *pIBaseFilter)
{
HRESULT hr = S_OK;
ISampleGrabber *pGrabber = NULL;
hr = pIBaseFilter->QueryInterface(IID_ISampleGrabber, (void**)&pGrabber);
if (SUCCEEDED(hr))
{
AM_MEDIA_TYPE mt;
ZeroMemory(&mt, sizeof(AM_MEDIA_TYPE));
mt.majortype = MEDIATYPE_Video;
mt.subtype = MEDIASUBTYPE_RGB24;
mt.formattype = FORMAT_VideoInfo;
hr = pGrabber->SetMediaType(&mt);
}
if (SUCCEEDED(hr))
hr = pGrabber->SetCallback(new SampleGrabberCB(), 1);
if (pGrabber != NULL)
{
pGrabber->Release();
pGrabber = NULL;
}
return hr;
}
Esse é praticamente o código exato do código fonte do CodeProject. Adicionei este método para definir a resolução:
void CameraMethods::SetCaptureFormat(int camIndex, int width, int height)
{
HRESULT hr = S_OK;
IMoniker* pMoniker = GetMoniker(camIndex);
IBaseFilter* pCap;
hr=pMoniker->BindToObject(0,0,IID_IBaseFilter,(void **)&pCap);
if(!SUCCEEDED(hr))
return;
IAMStreamConfig *pConfig = NULL;
if(g_pCaptureGraphBuilder == NULL) // no CaptureGraphBuilder initialised
return;
hr = g_pCaptureGraphBuilder->FindInterface(
&PIN_CATEGORY_CAPTURE, // Preview pin.
0, // Any media type.
pCap, // Pointer to the capture filter.
IID_IAMStreamConfig, (void**)&pConfig);
if(!SUCCEEDED(hr))
return;
int iCount = 0, iSize = 0;
hr = pConfig->GetNumberOfCapabilities(&iCount, &iSize);
// Check the size to make sure we pass in the correct structure.
if (iSize == sizeof(VIDEO_STREAM_CONFIG_CAPS)) {
// Use the video capabilities structure.
for (int iFormat = 0; iFormat < iCount; iFormat++)
{
VIDEO_STREAM_CONFIG_CAPS scc;
AM_MEDIA_TYPE *pmt;
/* Note: Use of the VIDEO_STREAM_CONFIG_CAPS structure to configure a video device is
deprecated. Although the caller must allocate the buffer, it should ignore the
contents after the method returns. The capture device will return its supported
formats through the pmt parameter. */
hr = pConfig->GetStreamCaps(iFormat, &pmt, (BYTE*)&scc);
if (SUCCEEDED(hr))
{
/* Examine the format, and possibly use it. */
if (pmt->formattype == FORMAT_VideoInfo) {
// Check the buffer size.
if (pmt->cbFormat >= sizeof(VIDEOINFOHEADER))
{
VIDEOINFOHEADER *pVih = reinterpret_cast<VIDEOINFOHEADER*>(pmt->pbFormat);
BITMAPINFOHEADER *bmiHeader = &pVih->bmiHeader;
/* Access VIDEOINFOHEADER members through pVih. */
if( bmiHeader->biWidth == width && bmiHeader->biHeight == height &&
bmiHeader->biBitCount == 24)
{
hr = pConfig->SetFormat(pmt);
}
}
}
// Delete the media type when you are done.
DeleteMediaType(pmt);
}
}
}
}
Percorri o código e verifiquei que a chamada para SetFormat () é executada e retorna um HRESULT válido. Porém, não há alterações nos quadros capturados.
Sem mensagens de erro, é difícil saber por onde começar. Espero que haja alguns especialistas do DirectShow aqui que vejam o problema. Eu ficaria feliz com uma boa e velha moda condescendente "Bem, sim, como você espera que a câmera mude o tamanho do quadro depois que o buffer for alocado no pilha de filtros e o widget é inicializado no foobar! Pft ... lol ";)
Ensine-me, oh DirectShow / COM deus!
[ATUALIZAÇÃO # 2] (Para sua informação, é estranho que não possamos adicionar uma nova mensagem a este sistema e precisar editar o original assim)
ugestão de @Per Roman Eu usei o GraphStudio para olhar sob o capô do meu gráfico. Admito que ainda não entendo exatamente o que estou vendo. Encontrei uma função "relatório de texto" e achei que seria útil postar esse relatório aqui, caso ele mostre informações valiosas.
