    20 août 2018, par Ankur Tripathi

    I am trying to capture video using FFmpeg and Directshow(https://github.com/rdp/screen-capture-recorder-to-video-windows-free) filter but it works sometimes and fails some time

    Start FFmpeg

    arguments= -y -rtbufsize 100M -f dshow -framerate 60 -i
    video="screen-capture-recorder":audio="Microphone Array (Realtek
    Audio)" -c:v libx264 -r 60 -preset ultrafast -tune zerolatency -crf 28

    Stop FFmpeg

        Call WriteInput("q"); 
    
    public void WriteInput(string input)
    
        {
    
            if (processRunning && process != null && process.StartInfo != 
    
                null && process.StartInfo.RedirectStandardInput)

  • Combining Youtube-dl and FFMPEG not working

    13 juillet 2019, par user1029296

    I am trying to download 5 second samples for a list of youtube video. The traditional approach is to download the entire file with "youtube-dl" and then use "ffmpeg" to split it however you want it.

    I am trying to use the following method : https://github.com/ytdl-org/youtube-dl/issues/622#issuecomment-162337869

    It does work when I include the variables in the command, for example :

    ffmpeg -ss 0 -i $(youtube-dl -f best --get-url https://www.youtube.com/watch?v=ySVi-0RS5vI&t=5s) -t 10 -c:v copy -c:a copy title2.mp4

    However, I am having issues trying to automate the system. Specifically, I would like ffmpeg and youtube-dl to read a file and use the values. I created the file "youtube.txt" which includes the following codes :

    440.8,https://www.youtube.com/watch?v=0-4wOE_DNeA,661.2,881.6,0-4wOE_DNeA

431.2,https://www.youtube.com/watch?v=006BQU3BFxw,646.8,862.4,006BQU3BFxw

    I am using the following command :

    parallel -j 6 --colsep ',' ffmpeg -ss {1} -i $(youtube-dl -f best --get-url {2}) --t 5 -c:v copy -c:a copy {5} :::: youtube.txt

    However, I get the following errors :

    ERROR: '{2}' is not a valid URL. Set --default-search "ytsearch" (or run  youtube-dl "ytsearch:{2}" ) to search YouTube
    
--t: No such file or directory

    Would you mind helping me ?

    Thanks !
