Video and audio stream format used by FFmpeg, a tool used to encode video and audio; stores recorded video and audio streams, or feed, that is sent to the ffserver for publishing.
FFmpeg is a media framework that consists of a variety of components, which includes:
- ffmpeg - Command-line tool used to convert audio and video formats. It can also convert live video and audio.
- ffserver - HTTP and Real Time Streaming Protocol (RTSP) server used to stream multimedia for live broadcasts.
- ffprobe - Command-line tool used to show media information.
- ffplay - Utility used to play media files.
You can use FFM files to replay video that was recorded at an earlier time, but the ffserver parameters must match the original parameters that were in place when the file was created.
