The simplest Video Encoder Based on FFmpeg-new version (YUV encoding is HEVC (H.265 ))An example of a video encoder based on FFmpeg was created a while ago:The simplest Video Encoder Based on FFMPEG (YUV encoding: H.264)In this example, YUV pixel data (YUV420P) can be encoded as H.264 code streams. Because FFmpeg now s

FFmpeg is a popular multimedia framework. Its detailed functions are not described much. For more information, see Wikipedia. The latest ffmpeg 2.2.2 version has been released recently. For release information, see the announcement on the official website. This article will teach you how to install FFmpeg 2.2.2 On Debian Jessie, Debian Sid, and Debian Wheezy sys

FFmpeg has very powerful functions including video capture function, video format conversion, video capture, video watermark, etc., the core functions of the following. 　　Video Capture function FFmpeg video capture function is very powerful, not only can collect video capture card or USB camera image, but also For screen recording, but also supports the RTP streaming of video to the support RTSP stream M

It's always a problem to toss this whole day yesterday. Today, we finally found an English installation guide. Follow that step-by-step installation, very smoothly installed OPENCV2.4.3+FFMEPG. To summarize, the methods mentioned in yesterday's blog mainly have two problems that ultimately lead to failure: 1. Under 64-bit systems, configuring external libraries such as x264 requires the use of-fpic tags for configure ./configure--enable-shared--enable-pic 2. Under 64-bit systems, when conf

Debugging is a very effective way to work with the code in the process. The project that we used to build in Visual Studio makes it easy to debug the program. But for a project like FFmpeg, it's not so easy to get a single-step debug. If you have to debug run FFMpeg, it's best to follow the instructions in our previous blog post to compile, and put it in eclipse for debugging.Before you begin, you need to i

Version Ubuntu10.10, refer to some compilation methods on the Internet. 1. Download git. According to the official documentation, download and compile ffmpeg requires git implementation.

Previously, "Install FFMPEG in Ubuntu to support 3GP format" was installed in Ubuntu server8.04. With the upgrade of Ubuntu and the effectiveness of some libraries, there will be various errors during the installation process. Now I will refer to the article on installing FFMPEG in Ubuntu server9.04Article(From http://marshal.easymorse.com/archives/1635) The Installation Steps mainly refer to fakeoutdoors

1, FFMEPG structure description1.1 "IntroductionFFmpeg (Fast Forward movingpictures experts Group) is a complete solution for the separation, conversion, encoding and decoding of audio and video and streaming media, the most important of which is the Libavcodec library, which is a set recording, conversion, sound/ Video encoding and decoding functions as a complete open source solution. The development of FFmpeg is based on the Linux operating system,

The simplest FFmpeg-based AVDevice example (screen recording ),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 output data to a specified multimedia device. We plan to write two examples of libavdevice class libraries related to FFmpeg. The previous a

Let's talk about my compilation environment: macos10.8.3, xcode4.6 (4h127), and ios6.1. This document provides methods for compiling lib libraries such as FFMPEG i386 (simulator), armv7 (iPhone 3gs or above), and armv7s (iPhone 5, finally, we provide a script that combines these three versions into a common lib library. The simulator and the real machine only need a set of library files. 1. Prepare command line tools in advance and download the

FFmpeg is an open-source and free cross-platform video and audio stream solution that uses lgpl or GPL licenses. FFmpeg is easier to compile in Linux. In Windows, it is relatively troublesome. The following software is required to compile FFMPEG: Msys:Minimal GNU (POSIX) System on Windows is a small GNU environment, including basic bash and make. Is the best

The following is a special summary of the technical experience and gains, mainly about the actual problems and solutions encountered when using FFMPEG, and will also recommend relevant online materials. I. formats supported by FFMPEG Formats that can be parsed by ffmpeg.exe: (ASX, ASF, mpg, WMV, 3GP, MP4, mov, Avi, and FLV ),Mencoder can be used to convert files that cannot be parsed by ffmpeg.exe (such

In the actual software engineering project, it is precisely because of these characteristics of object-oriented, this method of analysis is widely welcomed and continues to develop, the recent development of the framework of the Java EE project is the best example, whether the object injection or Pojo to the object-oriented approach to add more new vitality.From "1" you can see a simple example of process-oriented and object-oriented analy
