h264 codec vlc

There are a few words in this article, that is, I want to talk about a problem of today's research. Recently, a security system needs to obtain stream data from the camera and store it as a file. Our project uses the cameras of multiple merchants, and the types of files stored are different. One of them says that their data is h264, but VLC cannot be broadcast, I used a hex system to view my parsed video f

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 high. The general system will provide a GPU or a

After reading the introduction of H264/AVC codec, I just left the following three articles in my mind:1, H264 does not understand how to implement a codec, just a coded video bit stream syntax, and the Bitstream decoding method, this is similar to MPEG.2, H264 and once the s

System FrameworkPrinciple Description:Adopt distributed network system, install video client software on mobile phone, install camera Server software on remote server, collect camera real-time video, carry out H264 encoding, and publish it in the form of custom TCP server, and use the client software to enter the IP address of the server. Connect and watch live video.Feature Description:Currently learning version supports capture 320*240 video, server
