Well, memory leaks are bad. began to suspect that their own code problems, debugging for half a day, and repeatedly rewrite and optimize the code, or leak serious.Take the online ready-made ffmpeg H264 coded sample to test, the same leak is very serious.Baidu a bit, a lot of people encounter the same problem, they say is the memory leak of the code library itself .... , no words, ffmpeg, that H264 code can

These months have been doing the iphone audio and video things, because the individual is lazy, so has not tidied up, now idle egg pain, and later the project to be shelved, here to record what I do the iphone mobile push the stream of things.Projects are personal research and experimentation, there may be many bad or wrong places please forgive.1 Overview of features* Realization of audio and video data collection* Realize the encoding of audio and video data, video encoding into

how H264 (ES) packaged into H264 (PES) has been on the internet to collect all kinds of information, heart tired ah. The following nine locks are very complicated for you to explain the unknown relationship between TS and H264. first, the overall general diagram This I do not know is in which CSDN master that get the figure, helped me a lot of busy, on the p

Since the company bought a device that did not provide a decoder, I had to do the decoding work as a last resort. I found a circle on the Internet. H264 decoding is more convenient, which is a series of ffmpeg function libraries. The original equipment also uses this set of function libraries to decode. Using H264 decoding is divided into several steps: Note that you must add extern "C" when adding the

Recently began to engage in video-related things. have been afraid of H264, feel too difficult, now began to touch it slowly, understand it. Inadvertently, see someone on the net to H264 stream analysis. Address: http://blog.csdn.net/leixiaohua1020/article/details/17933821. There are commercial tools, such as H264videoesviewer, but money, and expensive, the company spends money on one (really "one"), only o

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!

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

Network Abstraction Layer Unit type (NALU):The Nalu header consists of a byte with the following syntax:+---------------+|0|1|2|3|4|5|6|7|+-+-+-+-+-+-+-+-+| F| nri| Type |+---------------+F:1 a bit.Forbidden_zero_bit. This one must be 0, as stipulated in the H.Nri:2 a bit.NAL_REF_IDC. Taking 00~11, it seems to indicate the importance of this nalu, such as 00 of the Nalu decoder can discard it without affecting the playback of the image.Type:5 a bit.Nal_unit_type.

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 there was a Chinese version, in addition, the g

It seems that the problem can only be solved in this way. Now we need to test more to prevent new problems. Currently, it does not affect the existing code, and the frame of the screen is directly blocked. Ideas:I asked about h264 decoding of the set-top box. They used hardware decoding. They simply set an interface provided by hardware decoding: Set the error processing mode.I think this error handling mode will definitely block the wrong frames, so
