There are many struct types in FFMPEG. The most critical struct can be divided into the following types: A) protocol http, rtsp, rtmp, mms) AVIOContext, URLProtocol, and URLContext mainly store the types and statuses of protocols used by video and audio. URLProtocol stores the encapsulation format used by the input video and audio. Each Protocol corresponds to a URLProtocol structure. Note: files in FFMPEG are also used as a protocol "file ") B)

Multiple critical security vulnerabilities in OS X Yosemite Emil Kvarnhammar from Swedish security company Truesec found multiple security vulnerabilities in OS X 10.10, codenamed Yosemite. He named it rootpipe. He published an article explaining how to discover these vulnerabilities and how to prevent them. These security vulnerabilities allow attackers to obtain the highest permissions of the machine, that is, root access, without a password. Curre

According to foreign media reports, Microsoft's new-generation operating system Windows Vista has revealed a fatal vulnerability that can crash the system within 10 seconds. As we all know, One of Windows Vista's biggest selling points is its security. Microsoft Chairman Bill Gates also said that Microsoft has made great efforts in the security of Vista. This also seems to be the case. Compared with earlier versions of Windows, Windows Vista is indeed more secure and many attacks and viruses a

Wen/Li Bo (Guang Yu guangzhen) The best and most critical property of quantum physics is "randomness", which is the "essence" attribute of quantum physics (fundamental,Intrinsic randomness ). The greatest randomness is the maximum amount of information. In the application of quantum information, "dequantization" cannot deduct two "randomness" derived from BB84-the randomness of transmission states and the randomness of particle functions.
