In general,. Net EXE assemly will have a corresponding *. EXE. config configuration file. When you need to read configuration information, you can directly read the key values in *. EXE. config through configurationmanager. etettings [Index], but there are few situations where DLL Assembly requires config file. If the current DLL Assembly name is test. dll, if yo

Before the article: FFmpeg is an open-source codec framework with powerful functions. However, if we use it for development, there is a severe polarization. the great gods are discussing profound issues, and most of the little white connections like me cannot go in. Recently, I accidentally learned how to get started. Now I write this series of articles "no basic learning video decoding" to help you get started. The blogger's development machine is ba

played a role. This reuse is referred to as "black box multiplexing".There are two types of executables in the Windows operating system, with the following suffix. exe and. dll. The difference is that the. exe file can be run independently of the memory, and the. dll file cannot, it can only be called by other processes. However, in any format, they are binary files. The above-mentioned "binary level" code

Here, cropping refers to timeline cropping, not space cropping. For example, you want to crop the video from 1 minute 20 seconds to 30 seconds and save it as a video. This is the question to be discussed in this article. IVideo Cropping FFmpeg provides simple command parameters: FFmpeg-SS start-T duration-I input-vcodec copy-acodec copy output The preceding command is explained in a bit. -SS start time,

There are too many cool people here. Come and ask.I am using the FFMPEG and mencoder command line encoding.ProgramSome ProblemsWhy does FFMPEG use the-SS and-T parameters to capture video clips and encapsulate them in MP4 format? However, if the video is encapsulated as MKV, the video will not be synchronized. However, when the first 1st frames of the video are static for a period of time, the video will st

Recently in the study of video-related technology, learned ffmpeg, on the internet to see how to transplant FFmpeg to Android, looked for a few days, look at a lot of things, is not a complete transplant successful, and finally through the production of various materials, combined with online information, Finally, the ffmpeg was done. Record it here.Overall conce

OnceReboot = 975.Year Before starting this article, I will make a small investigation: How many friends like reboot? Answer A: I like it. I need to reboot n times every day. Answer B: I don't like it. Do not reboot for a week. If there is no accident, I believe most people will be in B's category. After all, few people will be willing to interrupt what they do and save the articles and codes being edited, then restart and wait for a few minutes before re-opening the document and code editing.

"@" and then the function name, the symbol "@" and the number of bytes of the parameter are followed. For example, the modifier of the int func (int A, double B) function is @ func @ 12. For the "C ++" function, it is different.In the future, compilers may use different registers to store parameters. Functions declared in DLL using _ declspec (dllexport:_ Declspec (dllexport) only indicates that this function is a

Reduce the number of generated dll and the number of generated dll Before the opening, I want to despise myself. I don't need to write this thing at all. I already have something to implement. As my team lead said, there are too few open-source projects. In fact, this thing can be completely solved by ILMerge. Then let's talk about the preface. After developing things for a long time, we will always accumul

0 IntroductionWith the development of video coding and decoding technology, computer network technology, digital signal processing technology and embedded system, the remote video surveillance system with embedded network video server as the core has begun to emerge in the market. The system transmits the analog video signal from the camera directly into the video stream through the built-in embedded video encoder, which is transmitted through the computer network. Embedded network video server

In the past two days, I have studied how to obtain data from the DirectShow device by using FFMPEG. Here I will record it for memo. The methods described in this article mainly correspond to Windows platforms. 1.

Basic concepts of FFMPEG: Ffmpeg is an open-source codec framework that provides an audio/video recording, decoding, and encoding library. FFMPEG is developed in linux, but it also has a compiled version in windows.The ffmpeg project consists of the following parts:The command line tool for converting
