h264 video player

If the power of a person is limited, the power of the network is infinite. The purpose of studying h264 is to customize a streaming media player to play videos in real time. Fortunately, there are a lot of online cool people standing on the shoulders of giants, and the pressure will be much lower. Overall Player Design Scheme Generally, the overall

make the video transmission more fluent, now the video is used in compression coding. Here we will introduce the use of the X264 encoder to encode YUV420 data into H264 format video. YUV Data acquisition has been introduced in the previous: V4l2 video capture and

Use ffmpeg to encode the BMP image as a x264 video file and save the H264 video as a BMP image,The ffmpeg open-source library encodes bmp images into x264 files and decodes and saves the encoded H264 files as BMP files. Based on the blog code, you can build a test environment in vs2010. Resource download code: # Define

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

Http://bbs.chinavideo.org/viewthread.php? Tid = 7575 I believe many of you want to play h264 video streaming media like me. However, a newbie often does not know where to start. Using Baidu, Google, and other search materials is a treasure. After N weeks of thinking, I made some achievements. It took a lot of useless effort. I spent a week watching the English protocol, and later I learned that th

The new tags audio and video introduced in HTML5 implement native HTML support for video playback and audio playback. With this native HTML5 video player, we no longer need flash technology, the video and audio can be directly embedded into the webpage. HTML5

The recent need to encode H264 video into MP4 format. Research, one method is to use the FFmpeg library, you can first decode the H264 file, and then encode the generation of MP4 files, but this method is less efficient, 10M video may take a few seconds to complete. Another way is to encapsulate the

What is h264 video file format? H.264 is the latest format defined by the MPEG-4 standard, and it is also one of the most technically available video coding formats, representing the latest technology, some also called AVC (Advanced Video coding), a video compression standa

To put it simply, the MKV and AVI formats only encapsulate containers, which encapsulate video streams and audio streams. The container does not affect the image quality. What affects the quality is what is encapsulated in the container. Therefore, changing the container does not affect definition subtitle audio. I would like to add some basic knowledge about video. Maybe there is something wrong with it. F

IVideo Encoding 1.1 target of video compression and encoding 1) Ensure compression ratio 2) Ensure recovery quality 3) easy to implement, low cost, and reliability 1.2 starting point of compression (feasibility) 1) Time Correlation In a video sequence, adjacent two adjacent frames have very few differences. This is the time correlation. 2) Spatial correlation In the same frame, there is a large correlation
