quicktime h264

rtmp Server for output H264 live streamingRTMP (Real time Messaging Protocol) is a common streaming media protocol, used to transmit audio and video data, combined with flash, widely used in live, on-demand, chat and other applications, as well as PC, mobile, embedded and other platforms, is to do streaming media development often come into contact with the protocol. I have previously written an article, "rtmp protocol to send H. E encoding and AAC en

The raw stream data obtained from h264 is. Generally, the bitstream structure is SPS, PPS, I frame, P frame ...... SPS, PPS, I frame, P frame ............ When we use RTP to package h264 data, SPS and PPS can directly send I and P frames without sending them. It also depends on the size of I frame and P frame. If it is smaller than MTU, it can be sent directly with the RTP package. If it is larger than MTU,

Recently, I am working on an online tutorial Network project. I need to upload videos in any format to automatically play h264 standard videos using html5. Finally, PHP + FFMPEG is used for implementation. Here we will share our detailed solutions with you! Recently, I am working on an online tutorial Network project.

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
