mp4 video codec

Company Project reason, contact a bit of video stream H264 codec knowledge, before the project using the FFmpeg Multimedia library, using the CPU to do video encoding and decoding, commonly known as soft-coded soft solutions. This method is more common, but it consumes CPU resources, and the codec efficiency is not hig

knowledgeThis chapter focuses on where ffmpeg are used (here are just a few of the many I know, in fact much more than this). To illustrate: FFmpeg is very important.Use FFmpeg as the kernel video player: Mplayer,ffplay, shooter player, Storm av, kmplayer,qq av ... Use FFmpeg as the DirectShow Filter for the kernel: Ffdshow,lav Filters ... Use FFmpeg as the transcoding tool for the kernel: FFmpeg, Format Factory .

This article describes how php converts a video to an mp4 format using memcoder. it involves php video file operations and has some reference value, for more information, see the following example. Share it with you for your reference. The specific implementation method is as follows: The code is as follows: Convertize ("some-input-video.avi", "output.mp4 ")

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.

In doing a website, found that video files, such as the Flv,mp4 format can be played locally, but reached the development of the machine, it is not. The player's file address is right, or has not been responding. After a long experiment, the problem was found to be set with IIS. IIS does not allow video files to be played by default, and the solution is as follo

I just added a player to the page. The buttons didn't work. I don't know where the problem occurred. It was very depressing. So I collected the information and shared it with you, I hope this code can be used in my test.html to help you. You can use an absolute path such as c: \ test.html to access the video. However, you cannot play the video by accessing http: // localhost/test.html, I just added a player

Slice generates m3u8 List command: ffmpeg-i input.mp4-c:v libx264-c:a aac-strict-2-F HLS output.m3u8 The length of the default per piece (that is, a TS file) for this conversion command is the only last 5 piece of information that is saved by default in the 2s,m3u8 list file, that is, the player can only broadcast the last 5 TS video files in the pull stream. This is definitely not what you want, so luckily, FFmpeg provides parameters to change these
