我在 curl lib 上使用 curlpp，以便从 youtube 下载视频。
我设法下载了flv，但无法使用各种视频播放器打开它。
我使用了另一个 youtube 视频下载器并下载了完全相同质量的完全相同的视频，我注意到请求相同，文件大小也几乎相同 - 我认为这是问题所在，例如：MyVideo.flv - 4.55MB 工作视频.flv - 4.53MB
这是代码：
// Callback Function
size_t FileCallback(FILE f, char ptr, size_t size, size_t nmemb)
{
return fwrite(ptr, size, nmemb, f);
}
void GetVideo(std::wstring videoUrl)
{
FILE * file = fopen("C:\\locatin\\b.flv", "w");
if (file)
{
curlpp::Cleanup cleaner;
curlpp::Easy request;
// Set the writer callback to enable cURL to write result in a memory area
curlpp::types::WriteFunctionFunctor functor(utilspp::BindFirst(utilspp::make_functor(&FileCallback), file));
curlpp::options::WriteFunction *getFileOpt = new curlpp::options::WriteFunction(functor);
request.setOpt(getFileOpt);
// Setting the URL to retrive.
request.setOpt(new curlpp::options::Url(videoUrl));
request.setOpt(new curlpp::options::Verbose(true));
request.setOpt(new Timeout(2000));
std::list<std::string> headers;
headers.push_back("Connection: keep-alive");
headers.push_back("Keep-Alive: 115");
headers.push_back("Accept-Encoding: gzip,deflate");
headers.push_back("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
headers.push_back("User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10");
headers.push_back("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
headers.push_back("Accept-Language: en-us,en;q=0.5");
request.setOpt<HttpHeader>(headers);
request.perform();
fclose(file);
}
}
任何想法任何人？
谢谢。
