我正在使用 ofVideoPlayer 和 Poco::pipe 以及 of0.8.0、Visual Studio 2012、Windows 7。
#include "testApp.h"
#include "Poco/Process.h"
#include "Poco/PipeStream.h"
#include "Poco/StreamCopier.h"
#include <fstream>
using Poco::Process;
using Poco::ProcessHandle;
//--------------------------------------------------------------
void testApp::setup(){
std::string cmd("bonanza.exe");
std::vector<std::string> args;
args.push_back("csa_shogi");
Poco::Pipe outPipe;
ProcessHandle ph = Process::launch(cmd, args, 0, &outPipe, 0);
Poco::PipeInputStream istr(outPipe);
myPlayer.loadMovie("sample_mpeg4.mp4");
myPlayer.play();
}
//--------------------------------------------------------------
void testApp::update(){
myPlayer.update();
}
//--------------------------------------------------------------
void testApp::draw(){
myPlayer.draw(20,20);
}
//--------------------------------------------------------------
void testApp::keyPressed(int key){
}
//--------------------------------------------------------------
void testApp::keyReleased(int key){
}
//--------------------------------------------------------------
void testApp::mouseMoved(int x, int y){
}
//--------------------------------------------------------------
void testApp::mouseDragged(int x, int y, int button){
}
//--------------------------------------------------------------
void testApp::mousePressed(int x, int y, int button){
}
//--------------------------------------------------------------
void testApp::mouseReleased(int x, int y, int button){
}
//--------------------------------------------------------------
void testApp::windowResized(int w, int h){
}
//--------------------------------------------------------------
void testApp::gotMessage(ofMessage msg){
}
//--------------------------------------------------------------
void testApp::dragEvent(ofDragInfo dragInfo){
}
这段代码通过了构建过程，但是它在以下行崩溃了
ProcessHandle ph = Process::launch(cmd, args, 0, &outPipe, 0);
带有一条消息
Unhandled exception at at 0x7591C41F in emptyExample_debug.exe: Microsoft C++ exception: Poco::SystemException at memory location 0x0018F740.
有谁知道这里发生了什么？这是调用堆栈和输出..
