This article introduces the compilation and use of ffmpeg in ANDROID/NDK environment, FFmpeg comes with H264, AAC, MP3 decoder, but there is no (or no good) corresponding encoder. The corresponding encoder requires the use of a third-party library. The recommended third party libraries is x264 (H264 encoding), FDK_AAC (AAC encoding), lame (MP3 encoding).In order, the third-party library should be compiled f

FFMPEG and ffserver can be used together to implement real-time Streaming Media Services. The real-time data comes from the camera. If you consider the application and network conditions, the client will still lag behind the image obtained by the camera locally. In the worst case, the image will not even be visible (even farther ), here we are concerned about how FFMPEG and ffserver work together, understan
