In the previous article, the m3u8 analysis and the keyword section of the network live TV were described. In this chapter I will enumerate and analyze the m3u8 files of different data sources that I have met.The first: TS fragment address is a file name: http:\\www.xxx.com\01\xx\1.m3u8#EXTM3U #ext-x-targetduration:8#ext-x-media-sequence:92595#extinf:8,20121120t182851-04-92595.ts#extinf : 8,20121120t182851-0

Digital TV information
1. program description
In digital TVs, all information and signals, including videos, audios, texts, and images, are converted into data after being digitalized. Data should be packed according to the relevant standard (usually MPEG-2) before transmission, forming fixed length transfer (TS) packet, the MPEG-2 TS packet length is 188 bytes, an

Tick_check_oneshot_change after checking that both timekeeper and clock_event_device have dynamic clock conditions, the TICK_NOHZ_SWITCH_TO_NOHZ function switches to the dynamic clock mode:First of all, the function uses the Tick_switch_to_oneshot function to set the Tick_device's working mode to a single trigger mode, and replaces its interrupt event callback function with Tick_nohz_handler, then Tick_ The schema field in the SCHED structure is set to Nohz_mode_lo
(the Dellivery Multimedia Integration Framework)DMIF is the overall framework of multimedia transmission, which mainly solves the operational problems of multimedia applications in interactive networks, broadcast environments and disk applications. The interaction and transmission between client and server is established by transmitting the multi-channel synthetic bit information. By DMIF,MPEG4, you can establish a channel with special quality of ser
Avi,It can contain videos of different encoding formats.
Encapsulate a file like a bottle
Originally, the original video stream data is converted into a corresponding bit stream after being encoded, And the bit stream is encapsulated into the corresponding file format according to the protocol. The so-called encapsulation is to add different "headers" to the original video bit streams and cut them into different sizes. For example, after the original analog video adopts MPEG2 digital encoding,
FFmpeg is so powerful that you can do your job with a few simple commands.Put Darkdoor. [001-100].jpg sequence frames and 001.mp3 audio files use MPEG4 encoding to synthesize video files Darkdoor.avi:$ ffmpeg-i 001.mp3-i darkdoor.%3d.jpg-s 1024x768-author skypp-vcodec MPEG4 Darkdoor.aviFFmpeg also supports MOV format:$ ffmpeg-i darkdoor.%3d.jpg Darkdoor.movTo see which formats your ffmpeg supports, you can
You can find instructions on how to install and use terminal services on the Internet and in local bookstores. However, most of them provide users with unknown benefits for remote applications. With only a few operations, you can quickly deploy a terminal server that hosts the required applications in your environment. However, to meet user expectations, you must consider other situations.
If you are a terminal server administrator, you need to consider the following points by setting aside the
hellotr_en.ts file, "Hello! "A bunch of garbled characters appear!
Of course, it's hard to use linguist for translation, because you don't know what the garbled content is.
To solve this problem, let's start with the source lupdate.Lupdate
Purpose: extract the string to be translated from the source code file.
Suffixes of currently supported source code files:
java,jui,ui,c,c++,cc,cpp,cxx,ch,h,h++,hh,hpp,hxx,js,qs,qml
Here we only care about the source code files related to c ++ (qtjambi, qts

Abstract: combined with the psi/Si information table in a TS stream of DVB-C Cable Digital TV, this paper analyzes the PSI Information of MPEG-2 and the various tables in SI information of DVB, this gives you a clearer understanding of the functions and functions of each table.
Key words: Digital TV; TS stream; PSI information; SI information; Electronic Program Guide EPG
