hard decode solution for different mobile platforms that perfectly supports H.264/AVC, H.263, MPEG4 and other popular video coding, covering hundreds of multimedia formats.

In the previous article we built the environment and compiled the required FFmpeg library, this article discusses how to use the API functions provided by FFMPEG for the Solution Encapsulation (DEMUX) process of multimedia files. Before we explain, we need to understand some basic knowledge of multimedia files, prawns please drift over. Container format: Whether it is audio files or video format files, is a multimedia container, that is, container, such as the common video container for

Introduction to Android Multimedia developmentTransferred from: http://blog.csdn.net/reiliu/article/details/9060557First, multimedia architectureBased on the opencore of the third-party PacketVideo company, it supports all common audio/video/Still image formats including: MPEG4, H, MP3, AAC, AMR, JPG, PNG, GIF, etc. The function is divided into two parts, one is the audio/video playback (PlayBack), and the second is the record of the audio and video (

(ISO/IEC 14496-10): Advanced Video coding or Advanced video coding (Coding, abbreviation AVC): Defines a video codec (codec), AVC and XviD are MPEG-4 encoded, However, because AVC belongs to the MPEG-4 Part 10, in the technical characteristics than belong to MPEG-4 Part2 XviD to Advanced. In addition, technically speaking, it is consistent with the ITU-T H-I standard, so it is all called MPEG-4 avc/h.264.ITU-TITU Telecommunication Standardization Group (English: ITU Telecommunication Standardiz

. After compilation, run: Make install The installation of x264 is complete! Then compile and install mplayer. The steps are the same as before. Execute configure to automatically determine that x264 support is added, and then execute make to compile. I tried converting an rmvb into a x264 video mp2 audio. It took 40 minutes to complete the conversion, which was much longer than other encodings. Test script: #! /Bin/sh MP2_64 = "-oac lavc-lavcopts acodec = mp2: abitrate = 64" MPG2 = "-ovc la

the two parameters are the key to solving synchronous display of video and audio and preventing the input cache overflow or underflow of decoder. PTS indicates the time when the unit appears in the system target Decoder (STD: system target decoder). DTS indicates the time when all the bytes of the access unit are removed from the es decoder cache of STD. Each packet header of I, P, and B has a PTS and DTS, but PTS and DTs are the same for B frames and do not need to mark the data transmission o

that you are correct. I 've probably read the video materials. Currently, MPEG4 compression is quite mature. Algorithm In fact, many people confuse the MP4 file format with the MPEG4 compression algorithm. MPEG4 can only compress video data (the "video" data here refers to image data in the YUV format, which does not contain sound ), the related files indicate t

Principle of MPEG-2 SystemChapter 1 MPEG-2 OverviewWhat is MPEG and MPEG-2?MPEG is short for Moving Picture Experts Group. MPEG-2 is a digital video compression specification designed by MPEG and ISO organizations. It is mainly used on DVDs and DVB. The current standard document is iso13818.What is DVB?DVB, short for Digtal video broadcast, is a digital TV standard used by all European countries and other countries and regions. The American ATSC standard is also implemented based on the DVB stan

VLC-based video player and VLC Video Player I recently studied the video playback function, which was previously used by VideoView. After reading the video on the internet, I feel that it is not very good, and the supported formats are relatively small. Now there are various formats of online videos, and I feel that it is very limited to play with VideoView. Found a suitable player, Github address for https://github.com/xiaomo/AndroidPlayerLibrary. This player is based on the vlc software. After
