FFmpeg is an open-source platform for recording, converting, playing and streaming video and audio. It supports des libavcodec, a popular video/audio codec. Several popular Android applications are built based on FFMPEG, including rockplayer, moboplayer, acrmedia, vitalplayer, V-cut express etc. if you're developing multimedia applications that needs a video/audio codec,

FFmpeg is a popular multimedia framework that can be used to record, transform, and convert digital audio and video into streaming open-source computer programs. Use LGPL or GPL license. It provides a complete solution for recording, converting, and streaming audio and video. It contains a very advanced audio/video codec library Libavcodec, in order to ensure high portability and codec quality, Libavcodec Many codec are developed from scratch.It is al

I. PrefaceFFmpeg is an open source project based on Linux development, and its source code is incompatible with the C + + compiler provided by the most common Visual Studio under Windows, so it does not support msvc++ compilation. You need to configure a Linux-like compilation environment under Windows to compile.Compiling the dynamic-link library DLLs will make no difference in usage as with other dynamic-link libraries. You can use msvc++ to link these libraries to other programs, in other wor

The simplest example of an AVDevice Based on FFmpeg (reading a camera ),FFmpeg has a class library that interacts with multimedia devices: Libavdevice. You can use this library to read data from multimedia devices on your computer (or other devices) or output data to a specified multimedia device.Libavdevice supports the following devices as input: Alsa Avfoundation Bktr Dshow Dv1394 Fbdev Gdigrab

The simplest FFMPEG + SDL-based audio player ver2 (using SDL2.0) and ffmpegsdl2.0Introduction I have previously worked on a simple audio player: FFMPEG + SDL-based audio player, SDL1.2. Just two days ago, I updated the original "the simplest Video Player Based on FFMPEG + SDL" with SDL2.0, so I also updated the audio player to SDL2.0. SourceForge project home: ht

x264 is a H.264/MPEG4 AVC encoder, this guide will guide beginners on how to create high-quality H. S videos. For ordinary users there are usually two code-rate control modes: CRF (Constant rates Factor) and dual pass ABR. Bitrate control is a method that determines how many bits are allocated for each video frame, and it determines the size and quality of the file. If you need help compiling and installing libx264, check out the FFmpeg and x264 compi

These days to do project, one of the requirements is that the user uploads the video file to the server, and then the server automatically intercepts the video as the corresponding thumbnail image, the server-side language is written in PHP, find a half-day data, found that ffmpeg-php can meet the demand, So here's a quick introduction to the configuration and usage of the extension library.The test server environment Wampserver Version 2.1,php5.3.5,

Implementation of cross-platform player based on FFmpegFirst, Background introductionFFmpeg is a super-powerful open source multimedia codec framework that provides a complete solution for recording, converting, and streaming audio and video, including Libavcodec, Libavformat and many more multimedia libraries. FFmpeg is based on the Linux platform and can also run on Android (Linux, you know!). ), Windows, Mac, and other platforms.How important is

These two days I have studied the command for sending streaming media from FFMPEG. Here I will record it for memo.1. udp1.1. send the H.264 bare stream to the multicast address. Note: The multicast address ranges from 224.0.0.0 to 239.255.255.255. The following command sends the H.264 raw stream "Chunwan. h264" to the address UDP: // 233.233.233.223: 264 [Plain]View plaincopy FFmpeg-Re-I Chunwan. h264-vco

Recently, we are developing streaming media. on the server side, live555 does not support MP4, Avi, and other video container formats. Therefore, we plan to use FFMPEG for extension. Use FFMPEG to parse the MP4 file and parse it into the basic video stream format supported by live555 (such as H. 264, etc.) and audio stream format, and then use live555 to process the basic audio and video streams, and then s
