Http://zh.wikipedia.org/zh-cn/LibavcodecHttp://baike.baidu.com/view/856526.htmLibavcodec is a LGPL free software codec library for video and audio data encoding and decoding work. Libraries with this name have ffmpeg projects and LIBAV projects, but they are incompatible with each other.Libavcodec is an integration of many open source multimedia applications and frameworks. Common MPlayer, Xine, and VLC med
Technical analysis: Introduction to video encoding and encapsulation formats
We are talking about HD videos with a resolution greater than 1280x720, which is called SD in the field of display and home appliances ". Some videos have a resolution of 1280x528, which is actually 720 p on the wide screen. Only 1920x1080p videos are generally called full HD fullhd videos. Most of this horizontal evaluation produc
This article introduces a simple Video Encoder Based on FFMPEG. The yuv420p pixel data is encoded as H.264 compressed data. The code of the encoder is very simple, but every line of code is very important. It is suitable for a good study. After the code is clarified, the encoding process of FFmpeg is basically clarified. Although I have already completed the program, I still haven't made it clear in some pl
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 encode
H264 SVC is a technology that divides video streams into multiple layers of resolution, quality, and frame rate. It is an extension of H.264 Video Coding/decoding standard adopted by most video conferencing Devices today. Video conferencing equipment uses SVC technology to send and receive multi-layer
The simplest Video Encoder: Based on libx264 (encoding YUV is H.264), libxpolicyuvThis document records a simple H.264-based H.264 video encoder. Previously recorded H.264 encoders were encoded Based on FFmpeg calling libx264, for example:The simplest Video Encoder Based on FFMPEG (YUV

In one of my favorite movie scenes, Clark W. Griswold (played by Chevy Chase in "Crazy Christmas Holidays") trapped himself in the attic while hiding Christmas presents. To keep warm, he wore pink gloves, green hats and brown fur shawls found from dusty closets. At the bottom of the wardrobe, he found a family movie that had been recorded since he was a teenager. With tears in his eyes, he finished the film with an old film projector.
Since then, family movies have gone through a long journey,
Introduction to Audio/Video Encoding
1. Tools used:
Mplayer (command line-based player)
Mencoder (command line-based Transcoder)
Firefox (graphical browser)
2. Any video can be played in three steps: Unpacking-> decoding-> Rendering, Corresponding to the player separator (demuxer)-> Decoder (decode)-> Renderer.
(1) unpackingThat is, the process in which the play
In the previous article, I talked about how to use JNI for h264 encoding, but the efficiency is not very practical.
After several days of hard work, refer to the real-time coding problem of Android with reference to http://www.javaeye.com/problems/27244.
Two important classes: mediarecorder parcelfiledescriptor
Mediarecorder is a collection encoding class provided by Android, while parcelfiledescriptor is
The project uses video codec, which has been around for the last half a month. To be honest, it has taken a lot of detours and wasted a lot of time. Record your final results here, hoping to help others.

Today, I am talking about a pitfall that uses FFMPEG to write Video Encoding programs. It took me a lot of time to think about it. It is very difficult to break through the mindset in many cases. The following are incorrect encoding results: When using FFMPEG for video encodin
The next generation of browsers have added support for HTML5 standard video tags (regardless of M $, ogg open source media standards, promoted by the xiph community, are supported by all browsers (Chrome/chromium/Firefox 3.5 +/opera 10.5/safari4 (via xiphqt )). Firefogg is a Firefox extension that converts other videos into Ogg formats.
Visit the firefogg website to download this extension. It supports Linux 32bit/64bt, Mac OS X, and Win32 platforms.
