  • Speed up start of a stream recording with ffmpeg

    15 janvier 2014, par neutron

    I try to record a video stream (from the web or a local webcam stream) and save it to a .mp4 / .flv file. I use FFmpeg with the version"N-59696-gc0a33c4".

    The problem isn't the recording of the stream, it is, how log it tooks to start the recording.

    This are the parameters i used to capture the stream (the stream is some random stream I found on the web) :

    ffmpeg.exe -i mmsh://live.camstreams.com/cscamscape?MSWMExt=.asf -r 25 -t 60 C:\temp\video.mp4

    And leads to this output :

    ffmpeg.exe -i mmsh://live.camstreams.com/cscams
