Live555 supports most single-Stream files. It only supports *. mpg, *. MKV, and *. webm audio/video hybrid files. In fact, my goal is to expand the supported formats, such as Avi, so I will analyze the processing of MPG files.
MPG file processing involves many classes, and the relationships between classes are complex. For the RTP packaging process (completed in
Now many friends like to talk about video or TV play copied to the mobile device to watch, but a lot of electronic products support the format is not much, this tutorial for you to introduce how to use the full video converter of the beaver Socket conversion format.
Step one: download and install, we go directly to the Beaver WO Universal Video Converter on the website to download. You can then install the converter completely, depending on the installation tutorial.
Step Two: Run the Vide
MPG is a common video format, the MPEG standard mainly has the following five, MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21 and so on. MPG may be based on MPEG-1 (VCD) or MPEG-2 (DVD) of any compression standard, MPEG standard video compression coding technology mainly utilizes the motion compensation frame compression coding technology to reduce the time redundancy, using the DCT technology to reduce the spa

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.
First, the video format does not determine the definition. The definition of a video depend

This is a multivariate regression equation used to reveal the relationship between vehicle fuel consumption and vehicle properties, and attempts to answer the common question: is the automatic vehicle more expensive? In addition to the automatic file attribute, is there a greater relationship between other attributes and fuel consumption? The original Article is found in

FFmpeg provides simple command parameters:

The preceding command is explained in a bit.

You can use the method of the first point to create an object in the function body, or use new object () to assign values to each attribute.

object creation methods.
1. Original Method
Because object attributes can be dynamically defined after an object is created, many developers write code similar to the following when JavaScript is first introduced:
Var Car = new Object (); Car. color = "blue"; Car. doors = 4; Car. mpg = 25; Car. showColor = function () {return this. color;}; document. write (Car. showColor (); // output: blue
In the above Code, create the Car object. Then set sev

Function Car () {}; // assign all attribute methods to the prototype attribute Car. prototype. color = "blue"; Car. prototype. doors = 4; Car. prototype. mpg = 25; Car. prototype. showColor = function () {return this. color ;}; var Car1 = new Car (); var Car2 = new Car (); document. write (Car1.showColor () +""); // Output: blue document. wri
