Recently discovered some websites, can parse each big video website VIP. Think carefully, this is also a reptile, crawling is video data.First select a video site, I chose the film encyclopedia, and then choose the film soon released "a show."Analysis pageI'm using a Chrome browser, F12 into the view.

searches for plugin from the Plugin-path specified in vlcrc and the modules and plugins directories in the current directory.Most VLC functions are implemented through plugin. By default, VLC has a large number of dynamic plug-ins. For example, the official VLC 0.8.6e has 210 plug-ins. To speed up startup, VLC caches the plugin list in % appdata % \ VLC \ cache. The plugins-Cache option is set to 0 to disable caching plugin.Open a UDP multicast stream. The default port is 4567.For the RTP proto
TS is all called mpeg2-ts, the abbreviation for "Transport Stream". The mpeg2-ts format is characterized by the requirement to decode independently from any segment of the video stream. Some website video is the TS format, the use

To put it simply, the MKV and AVI formats only encapsulate containers, which encapsulate video streams and audio streams. The container does not affect the image quality. What affects the quality is what is encapsulated in the container. Therefore, changing the container does not affect definition subtitle audio.
I would like to add some basic knowledge about video. Maybe there is something wrong with it.

Slice generates m3u8 List command:
ffmpeg-i input.mp4-c:v libx264-c:a aac-strict-2-F HLS output.m3u8
The length of the default per piece (that is, a TS file) for this conversion command is the only last 5 piece of information that is saved by default in the 2s,m3u8 list file, that is, the player can only broadcast the last 5 TS video files in the pull stream.

First, Introduction
The MPEG2 system is used for AV synchronization and time labels for system clock recovery in the 3 levels of es,pes and TS respectively.
On the TS layer, the TS header information contains the program Clock Reference PCR (Programme clock Reference),
It is used to recover the system timing clock STC, which is consistent with the encoder end.
