PPAPI URLLoader fail to receive endless multipart response

[Arthur Dou]

Hi all,

I'm studying the URLLoader sample introduced  at official site, and trying to load multipart response of a server. While the 

response is an endless multipart content (without "--myBoundary--") which is actually a continuous video frames sent from 

an IP camera. 

While calling pp::URLLoader::ReadResponseBody, it keeps returning -1 (might stand for PP_OK_COMPLETIONPENDING) and 

the buffer remains empty. Is there anyway to access the endless multipart reponse from the server? To achieve my purpose, 

I just edit a bit of the original code, which post the received responses directly rather than store into a string variable: 

void URLLoaderHandler::ReadBody() {

  pp::CompletionCallback cc =

      cc_factory_.NewOptionalCallback(&URLLoaderHandler::OnRead);

  int32_t result = PP_OK;

  do {

    result = url_loader_.ReadResponseBody(buffer_, READ_BUFFER_SIZE, cc);

    if (result > 0) {

      AppendDataBytes(buffer_, result);

      ReportResult(url_, url_response_body_, true);

      url_response_body_.clear();

    }

  } while (result > 0);

  if (result != PP_OK_COMPLETIONPENDING) {

    cc.Run(result);

  }

}

Thanks for any of your replies,

Arthur

I'm not certain, but perhaps you can use SetStreamToFile?
