exponential GRUMB algorithm decoding process:When parsing the K-Order index Columbus Code, the first non-0-bit leadingzerobits is first searched from the current position of the bitstream, and then the value of Code_num is calculated according to the formula:Code_num = 2^ (leadingzerobits + k)-2^k + values;Where values are the first non-0-bit followed by (leadingzerobits + K) bits.Example (1-order exponential GRUMB algorithm decoding 001011): leadingzerobits=2;values=011b=3;code_num=2^3-2^1+3=9

Previous HiSilicon H264 decoding library ,It realizes the simple decoding of H264 frame, but after replacing the camera, there is a watermark problem in the center of decoding video, such asFind the network, the basic related to this article, has not given a good solution.http://bbs.csdn.net/topics/390325547which warrior knows: HiSilicon H.

It took me nearly three weeks to implement HTTP live streaming on the crtmpserver to package h264 and aac into ts streams and play them on the iPad through HTML5, because there is no ready-to-useCodeFor reference, the packaging code is all handwritten. For the packaging format, refer to ISO/ice 18318-1.pdf. During this period, I encountered many problems and took a lot of detours. The standard-compliant ts may not be able to play on the iPad, but the

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 video streams consisting of a small base layer and multiple other optional layers that can improve resolution, frame rate, and quality. This layered met

Last Post hardware video encoding, after the default parameters are set, encode 1000 frames 640x480 H264 file size is about 180m, very large, you must set the parametersAfter the test discovery is Enablembratecontrol, the encoded data begins to shrink significantly:Here the first 54 control parameters are all initialized-1, in these 54 parameters, including h264,h263 and MPEG video format settings, for each

Thanks to Dr. Rai for the Chinese video codec in the pay, http://blog.csdn.net/leixiaohua1020 Recently to do some video streaming things, to parse H264 bare stream and get OPENCV format of mat data to the algorithm engineers to run algorithms. Related resources have been difficult to find, often too old to make the API version of the replacement, no way to let new people or laymen [such as me] Quick validation of the code is feasible.

H264 is a new generation of coding standards, high compression high-quality and support a variety of network streaming media transmission is known, in terms of coding, I understand his theoretical basis is: reference for a period of time, the statistical results show that in several adjacent images, there is generally a difference in pixels only 10% of the points, The difference in brightness does not change beyond 2%, and the chroma difference is onl

Have such a demand, give you a h264 raw data file, let you play directly out, how to implement?The idea is that the H264 raw data format is 0x00000001 back with 0x67 0x68 0x65 0x41 Such data, decoding requires a complete NAL data unit, We need to read the data from each 0x00000001 and the next 0x00000001 before decoding it to the decoder.Read the file I will not wordy, this article mainly explains how to ob

next sequence, that is, the image generated a complete frame A1, then the image is referenced A1 generation, Write only the difference between the A1 and the content.In the H264 protocol defines three kinds of frames, the fully encoded frame called I-frame, referring to the previous I-frame generated by only the difference part of the encoded frame called P-frame, there is a reference frame encoded before and after the frame is called B-frame.The cor

This article outlines:This paper introduces the famous open source audio and video codec library ffmpeg how to decode H264 stream, and elaborates its h264 stream input process, decoding principle and decoding process in detail. At the same time, most of the application environment, the original stream video size display is not the best way, so developers need not only to decode the video stream, and need to
