If a TS stream is used, several hundred streams of more than 2 m are supported and will not be dropped.D) Av syncIsma's AV sync is implemented according to * time stamp in RTP. Therefore, in the same step, you must wait until the RTP of the audio and video arrive before achieving AV sync. T
Simple cat command implementation
The CAT tool is easy to implement. The following code uses the basic open, read, printf, and close functions to basically implement the cat command function:

Rsync -- exclude files and foldersHttp://articles.slicehost.com/2007/10/10/rsync-exclude-files-and-foldersVery common: I want to synchronize/usr/boot/Under/, but I don't want to copy/proc/tmp folders.If you want to avoid a path, add -- exclude directly.For example, -- exclude "proc"-- Exclude 'Sources'Note: the directory path is relative to the folder you are backing up.Note: This path must be a relative path, not an absolute path.

In this section, we start with the simplest examples and learn the usual usage of the Program_options library. The following example is just a snippet of code, and the complete example is in the "Boost_root/libs/program_options/example" directory. For all examples, the assumptions are in the following namespaces:namespace PO = boost::p rogram_options;Quick StartThe first example is as simple as possible: It consists of only two parameter items. The code is as fol

The connection is complete (figure 1); If your TV does not have an S terminal, you can use the "S-av adaptor" provided by our shop, and connect its S terminal head with S terminal line. The AV head on the other end is then plugged into the AV video input port behind the TV, and is connected (Figure 2).
