FFmpeg + mencoder can basically complete any audio/video processing operations on the current web-based podcast platform. if you still need to add something, it is the online video recording function, which can also be completed using FFMPEG + FMS, therefore, some visible functions similar to YouTube can be implemented in the background in FFMPEG + mencoder + FMS

Recently because of the project needs, must modify the FFmpeg source to modify to meet the needs of the project, but I have never to compile and use the FFmpeg source code, has been compiled with someone else's SDK, coupled with the custom vs convenient compilation environment, It is really difficult to compile and debug so many sources of code under Linux. There is no good in Linux under the integrated dev

Brief Introduction FFmpeg is a free software that can run video, conversion, and stream functions in multiple formats of audio and video [1]. contains libavcodec, a decoder library for audio and video in multiple projects, and libavformat, a library for converting audio and video formats. Prerequisites Because the installation package cannot be found when yum install ffmpeg is used in CentOS, you need to in

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
