Referring to frame capture example: /usr/local/driveworks-2.2/doc/nvsdk_html/image_usecase1.html
and samples/image_capture
Initialisation is like this:
dwFrameCaptureParams frameParams{};
std::string params = "type=user";
// std::string params = "type=file";
params += ",format=h264";
params += ",bitrate=8000000";
params += ",framerate=30";
// params += ",file=video.h264";
frameParams.params.parameters = params.c_str();
frameParams.width = imageWidth;
frameParams.height = imageHeight;
frameParams.mode = DW_FRAMECAPTURE_MODE_SERIALIZE;
frameParams.params.onData = (dwSensorSerializerOnDataFunc_t) &doSerialize;
CHECK_DW_ERROR(dwFrameCapture_initialize(&m_frameCapture, &frameParams, m_sal, m_sdk));
Callback function is like this:
void doSerialize(const uint8_t *data, size_t size, void *userData) {
std::cout << "Hello!" << std::endl;
(void)userData;
(void)data;
(void)size;
}
Capture inside loop is like this:
CHECK_DW_ERROR(dwFrameCapture_appendFrameCUDA(image, m_frameCapture));
// this is where it segfaults
Please help, not sure why it doesn’t work!
