  • Speed up start of a stream recording with ffmpeg

    12 mai 2021, 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 :

    The problem now is, that it takes around 6-10 seconds until the recording starts after I entered the command.
