  • Precise syncronized stream Recording

    15 octobre 2020, par LuckyLuke1984

    I have multiple streams from cameras and I would like to capture an event from different point of views. My program opens at the moment X at once for each of these streams a different process that is calling an instance of ffmpeg to record the stream.
The problem is that the moment Y where the event happens is not exactly after Z seconds in each recorded file. There is a mismatch between each stream, resulting from different starting times of the videos.

    


    How can I trigger the start of the recording more precisely ?

    


  • ffmpeg generate video from images timestamped

    11 février 2020, par user3262532

    I have a set of timestamped image as input and I want to generate a output video from it.

    My command is :

    ffmpeg   -f image2 -ts_from_file 1 -i './%*.jpeg'    './video.avi'

    As output I get many errors :

    ....

    The output video is not properly generates, the video file has the good framerate but visually the video is run too quick.

    I try many commands to get proper output but I can get it.

  • Redact parts of an audio file using python (FFMPEG)

    18 août 2020, par K3rn3l5

    I have a use case where I need to dynamically redact parts of an audio file using python. For example sometimes I may have to remove between timestamps 10 to 15 and other times between 5 to 7, 12 to 16 and 21 to 26 . I have tried looking at FFMPEG and think it may be possible with filters or chaining filters, but I am having trouble figuring out which ones to use and the combination. Any help or pointers will be highly appreciated. TIA !
