The simplest example of an AVDevice Based on FFmpeg (reading a camera ),FFmpeg has a class library that interacts with multimedia devices: Libavdevice. You can use this library to read data from multimedia devices on your computer (or other devices) or output data to a specified multimedia device.Libavdevice supports the following devices as input: Alsa Avfoundation Bktr Dshow Dv1394 Fbdev Gdigrab

own property is separated by a colon, the property and filter are connected by an equal sign, and multiple filter Components form a filterchain, Each filterchain is separated by a semicolon. Avfilter in the command-line tool is-VF or-AF or-filter_complex, the first two correspond to single input video filters and audio filters, and the final Filter_complex corresponds to multiple input. In addition to being used in the FFmpeg command-line tool, Avfil

?? FFmpeg has a class library that interacts with multimedia devices: libavdevice. You can use this library to read data from multimedia devices on your computer or output data to a specified multimedia device. We plan to write two examples of libavdevice class libraries related to FFMPEG. The previous article documented an example of using the libavdevice class

according to the coding process logic realization. If we look at the overall architecture, x264 uses this kind of interface to realize the weak coupling and reusability, and uses the x264_t as the consistent context to realize the information encapsulation and polymorphism.This article is about to analyze the code architecture of ffmpeg/x264, focus on the implementation of C language to achieve object-oriented coding, although not forcibly to C + +,

Compile FFmpeg in Ubuntu Previously, we successfully used mingw + msys to compile FFmpeg on the Windows platform (see examples and generate ffplay.exe. Now recompile on the Ubuntu platform. Compared to the time-consuming and extremely difficult work required for compiling on Windows, compiling FFmpeg on Ubuntu is very

COMPILATION AND USE OF FFMPEG Today we will introduce how to compile FFMPEG FFmpeg is a very powerful Open-Source Audio/Video Codec library that can recognize many formats. Next we will introduce how to compile and install it from the source code: 1.Download ffmpegat http://ffmpeg.org/download.html.Ffmpeg-0.10.3.tar.bz2 2. Decompress:Tar jxvf

With the completion of my graduation thesis, I finally made room for free these two days, and I had time to study FFMPEG. I thought that I had been engaged in FFMPEG decoding and seldom involved in FFMPEG encoding. So I plan to study FFMPEG encoding. I read some examples on
