ffmpeg examples

FFmpeg is an open-source computer program that can be used to record, convert digital audio, video, and turn it into a stream. It provides a complete solution for recording, converting, and streaming audio and video. It contains a very advanced audio/video codec library Libavcodec.This program has only command-line mode, so when installed under Windows, it is different from the general installer, the specific installation steps are as follows:One,

Compilation environment: Ubuntu 12.04 NDK version: android-ndk-r8d FFmpeg version: 1.2 New Android project to create a JNI folder in the engineering directory 1, under the JNI directory to add the following file Android.mk, the contents are as follows: Include $ (all-subdir-makefiles) 2. Under Jni/ffmpeg, add android.mk content as follows: 3. Add Av.mk under Jni/

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 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

I don't know what avcodec_version () is, it should be to get the version information, but I have not studied FFMPEG in depth. Here, we mainly want to record the experience we have gained from one day, so as not to forget it for a long time, but also hope to giv

Now very popular live, I believe a lot of people are like me very curious how this technology is implemented, just recently in a ffmpeg project, found that the tool is easy to do live, the following to share the following technical points:First you have to compile the ffmpeg to run the required static library, this Baidu has a lot of content, here I will not say, the proposal can be used on GitHub, an open

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,

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
