This article describes a C # implementation of a method by ffmpeg from an FLV video file. Share to everyone for your reference. The specific analysis is as follows:Need to download FFmpeg first, this is open source, the code is as follows: The code is as follows:Using System; Using System.Configuration; public class PublicMethod:System.Web.UI.Page { Public Publicmethod () { } File path public static string
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

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.

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

After a day of hard work today, we have some gains. We successfully used JNI to call a method in libffmpeg ----- avcodec_version (). 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

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
