数据链路层分为两个子层:逻辑链路控制子层(LLC,LogicLinkControlsublayer),介质访问控制子层(MAC,MediaAccessControlsublayer)。相关知识点: 试题来源: 解析 正确 局域网将数据链路层划分为两个子层:逻辑链路控制LLC子层和介质访问控制MAC子层,从而使LAN体系结构能适应多种传输介质。因此,对各种类型的局域网来说,...
Media control access layer 1、MACA无限局域网协议:是IEEE802.11无线局域网标准的基础 2、RTS请求发送:包括源地址、目的地址和通信所需时间(包括确认帧) CTS允许发送:包括持续时间 源站在发送数据帧之前先发送一个短的控制帧,叫做请求发送 3、MACAW无线局域网协议 对MACA协议做了改进,提高了性能 主要改进 • 对...
The receiver has no role in this sublayer irrespective of the network topology. Fig. 16.12 illustrates some commonly used MAC procedures. Sign in to download full-size image Figure 16.12. Media access control methods. Popular MAC procedures are: • Master–slave: Here, the master controls the...
Supported values are webrtc.vp8.N-layer, android.generic.N, android.generic.N+M and none, where N denotes the total number of non-bidirectional layers (which must be at least 1) and M denotes the total number of bidirectional layers (which must be non-negative). <p class=note>android....

We'll loop while it has packets (av_read_frame), for each packet we need to re-calculate the PTS and DTS to finally write it (av_interleaved_write_frame) to our output format context.while (1) { AVStream *in_stream, *out_stream; ret = av_read_frame(input_format_context, &packet...
You need to make sure that AME has the rights to access the Documents folder (where all preferecnes are stored) or Adobe Support files such as plug-ins. You should be able to set that up with AntiVirus, plus all folders & drives that you need for encoding as well. However, we ...
