  • FFmpeg recording works on one laptop but not the other

    30 novembre 2019, par Jason T

    The following command :

    ffmpeg -f dshow -framerate 30 -video_size 640x480 -i video="HD Pro Webcam C920" out.mp4​

    works on one laptop (with C920 LogiTech camera) (Im calling it GOOD LAPTOP). It outputs a recorded video. But it will fail on another laptop (called BAD LAPTOP) and by fail on another I mean - it doesnt output a video (see below for output).

    The suggestions are to change parameters based on the specific error that occur on BAD LAPTOP. I have tried many different suggestions but they dont seem to work. Furthermore, they dont provide much insight into the underlying cause of the problem.

    Ive used the same camera on both laptops. Im using static windows binaries downloaded from FFmpeg web-site (veranoe). Please note the versions used below were different but that doesnt appear to matter.

    Trying to diagnose. Anyone have an idea of where the problem may lie. It seems to indicate a problem at the level of the system / camera setup.

    Please note that I’ve updated BAD LAPTOP but still no dice. Also please note that Ive tried this on several systems already and it seems to run ok (i.e., produce an output video)

    BAD LAPTOP :

    $ ffmpeg -y -f dshow -framerate 30 -video_size 640x480 -t 10 -i video="HD Pro Webcam C920" out.mp4

  • 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 :

    



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

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

    



    Is there a way to speed up this process ?
