For example to compute the CRC of the input audio converted to PCM unsigned 8-bit and the input video converted to MPEG-2 video, use the command: ffmpeg -i INPUT -c:a pcmu8 -c:v mpeg2video -f crc. This is the code to start (to run on MacOS): recordingProcessVideo = ffmpeg(`$:none`) You can select the output format of each frame with ffmpeg by specifying the audio and video codec and format. Every time you perform the encoding, you are modifying the stream a little (or maybe a lot). Here is my code var filePath null filePath 'video.mp4' var stat fs.statSync(filePath) var range. Since our codec is lossy, decoding a stream and re-encoding it will most probably result in a slightly different stream. I am trying to stream a video file with fluent-ffmpeg.

Starting is fine, but cannot figure out how to stop it. Ask Question Asked 2 years, 8 months ago. Would like a server request to start and another request to stop recording (links to a web interface - testing some tech with a view to making an Electron App later with it).

Recording from the screen/camera to an mp4 file. I'm using fluent-ffmpeg in a node application.
