FFmpeg is a very powerful audio and video processing tool, the official website is: http://ffmpeg.org/website Introduction FFmpeg is: A complete, cross-platform solution, can record, transform and transfer audio and video. FFmpeg can play video as well as command line tools to handle video, there is also a powerful video processing library for development, the fo

1. Relationships between the most critical structures in the FFmpeg There are many structures in ffmpeg. The most critical structures can be divided into the following categories: A) Solution protocol (HTTP,RTSP,RTMP,MMS) Aviocontext,urlprotocol,urlcontext primarily stores the type and status of the protocol used by AV. The Urlprotocol stores the encapsulation format used by the input video audio. Each of

Recently, due to freerdp, ffmpeg needs to be installed. However, yum cannot be installed and related rpm packages cannot be found for installation. You have to use the source code to install it in RedHat. For details, see the following steps. 1. Download ffmpeg. I am in this region Recently, due to freerdp, ffmpeg needs to be installed.

The more important functions and data structures in FFMpeg are as follows: 1.

This document records a video transcoding device based on FFmpeg on an Android platform. The transcoding is actually ported from the FFMPEG.C source code in the FFmpeg project. For FFMPEG.C source code can refer to the article "FFMPEG.C function structure simple analysis (Drawing)", here will not repeat the record.SourceThe directory structure of the project. The Java source code is in the SRC directory, an

We plan to record two examples of the simplest FFMPEG for memory read/write. All previous FFMPEG examples operate on files. For example, "100-line code implementation of the simplest Video Player Based on FFMPEG + SDL" plays a video file. The simplest FFMPEG-based transcoding program also converts a video file into ano

During video processing, you usually need to codec the video data. At this time, using the open-source FFMPEG video and audio processing solution is the choice of most programmers, after all, writing your own codecs is too inefficient, and in most cases it is not enough to write... However, it is only the first step to use FFMPEG, because it is quite troublesome to build the environment later. There are tw
