Movie files have a lot of basic components. First, the file itself is called a container container, and the type of the container determines where the information is stored in the file. Avi and QuickTime are examples of containers. Then you have a set of streams, for example, you often have an audio stream and a video stream. (A stream is just an imaginary word used to denote a series of data elements that are concatenated through time.) The data elem

Debugging is a very effective way to work with the code in the process. The project that we used to build in Visual Studio makes it easy to debug the program. But for a project like FFmpeg, it's not so easy to get a single-step debug. If you have to debug run FFMpeg, it's best to follow the instructions in our previous blog post to compile, and put it in eclipse for debugging.Before you begin, you need to i

During video processing, you usually need to codec the video data. At this time, using the open-source FFMPEG video and audio processing solution is the choice of most programmers, after all, writing your own codecs is too inefficient, and in most cases it is not enough to write... However, it is only the first step to use FFMPEG, because it is quite troublesome to build the environment later. There are tw
