test program Read video data and audio data from MP4 files, package them into ts streams, package them into RTP packets, and send them out. You can use VLC to receive and play videos. This section describes how the test program is developed in the IPTV development process supporting ts streams. Objective: To Read audio and video data from an MP4 file, package it into a TS stream, and save it as a TS file. You can use VLC or storm video to play the file. 1. Read MP4 files and obtain audio and
can we implement VG extension and LV extension? In fact, when PV is put into VG, We need to divide all the space of the physical volume of PV into one physical block and one storage unit. This block is not a file system block, but a PE (PhysicalExtend physical disk area). As long as the physical volume is added to the VG, the PE size in the new volume must be the same as that in the VG. This document describes how much PE the VG uses when creating the VG. [PE] (Physical Extend) Physical disk ar

1. Dependency-check can check for known, publicly disclosed vulnerabilities in project dependency packages. Currently good support for Java and. NET; Ruby, node. js, andPython are in the experimental phase, and C + + is supported only through (autoconf and CMake). The owasp2017 Top10 is mainly available for a9-using components with known vulnerabilities. Solution to the problem2, Dependency-check has command line interface, MAVEN plugin, Jenkins plug-ins and so on. The core function is to detect
First, ES flow:Also called the basic Bitstream, which contains the continuous stream of video, audio, or data.Second, PES flow:Also called the basic code stream of packaging, is the basic stream es stream according to the need to divide the length of the packet, and add Baotou to form a packaged basic bitstream pes stream.The original stream is divided into many PES
During the internship did a TS code flow analysis of the project, summed up some knowledge, share to everyone, may have written errors and omissions, welcome correction 1. The relationship between TS 1.1 ts Flow and other flows ES (Elementary Stream): Basic code flow, not segmented audio, video or other information of the continuous stream. pes (packetized Elementary Stream): a packet of basic code flow, the Basic code flow ES stream according to the

Concept: A single data stream composed of one or more pes with a common time benchmark is called a program stream ). ES is a data stream directly from the encoder. It can be a collectively referred to as an encoded video data stream, audio data stream, or other encoded data streams. The es stream is converted to the PES package after it passes through the PES
size of the original file system, we only need to adjust the/home size to use a larger partition, and then we can return to the business. Of course, lvm can also take snapshots of itself, which enables us to back up some unmovable targets. Second, basic components of LVM Physical Media ----- The Physical Media, which indicates that it is only a hard disk or a partition, such as/dev/hda,/dev/sda,/dev/sda4, and so on.
