C # video Surveillance series (4): Client--Audio receiver and screenshot

Objective

Because the audio received this piece of code and description is not much, and screenshot features written together, let ' s go!!

First, wrote three articles, to a sketch of the interface, so that everyone has a number of hearts.

Second, audio acceptance

Audio accepted code is relatively simple, the server side is open by default, as long as you will pick up on board card connected with the aid 1/2/3/4 white line on it.

VC + + Code:

if　(nn1　>=　0　)
　　　　{
　　　　　　　　MP4_ClientAudioStart(nn1);
　　　　　　　　MP4_ClientAudioVolume(0xfff0);
　　　　}

　　　　　　　　　　　　　　　C# Code:

　　　　　　　　　　　　if　(cs　>=　0)
　　　　　　　　　　　　{
　　　　　　　　　　　　　　　　PcHikClient.MP4_ClientAudioStart(cs);
　　　　　　　　　　　　　　　　PcHikClient.MP4_ClientAudioVolume(0xffff);
　　　　　　　　　　　　}

Note the range of volume values set by Mp4_clientaudiovolume: (0-0XFFFF).
