Profile) A configuration is a set of description data of an ASF configuration. One setting must contain at least one stream configuration setting. Stream informationThe stream information in the settings includes the bit rate, buffer window, and media attribute settings of the stream. The stream information of video and audio accurately describes the media configurations in the file, including the encoding and decoder used for compressing data (if any

state of old bottles of new wine for 40 of years, and of course the details are constantly being optimized. The structure of code stream in H We first understand the code flow structure, and the reason for this design, understand the code flow structure, the process of encoding and decoding has a specific backing. In fact, the specification is also the first regulation of the code flow structure, and then the structure of the decoder (for the structu

In simple terms, it is more cumbersome to use the method two than the method one, but the gains are more customizable.Using method Two o'clock, you need to use Avfoundation to obta

This document uses the h264 video stream as an example to decode the stream data. To highlight this point, this article only focuses on decoding video stream data and does not involve anything else (such as the configuration of the development environment ). If you need this information, please contact me. Prepare Variables Define avcodeccontext. If you use a class, you can define it as a class member. It is defined as a global variable. Static avcodeccontext * g_pcodecctx = NULL; Defines an

between Ethernet and ATM networks. When reliable and adaptive (good enough) channel access is strictly ordered (perfect), satisfactory approaches are generally more popular due to diversity. Another reason to avoid using synchronization when designing VoWLAN systems is that these systems are not operating in a closed environment. The main selling point of using WLAN to transmit voice is to enable dual-mode mobile phones and other voice devices to utilize the existing WLAN infrastructure. Next-g

The PES package consists of Baotou and payload , and the specific format is summarized as follows:You can see that Pts/dts is in the PES package , these two parameters is the key to solve the video-audio synchronization display, to prevent the decoder input cache overflow or underflow.PTS indicatesDisplay Unitappear inSystem Target Decoder
