  • FFmpeg Video Library Quick Review

    3 juillet 2019, par Rich_F

    I’m in need of reducing 18 videos so I can review them daily. I’d like to script some kind of compression or sampling using FFmpeg to not have to sit through 6 hours of video every day.

    What is the best way to review 6 hours of videos captured every day on SD cards ? The videos come in two cards, a 32 GB card ( 4 hours) and a 16 GB card ( 2 hours).

    Currently, I’m concatenating all videos and creating a screenshot every 3 seconds, which seems the longest I can go without missing something in the field of view (a vehicle will enter/leave). Still, this is thousands of images per card, and I select all, then preview and scroll down using page up/down. Any vehicle quickly appears in the thumbnails. This system isn’t bad, but I’m always inquisitive. I’m looking for more ways of sampling or seeing if any motion detection or frame analysis might register where I should be looking in my library of original captured videos.

    Options :

    1. Motion capture by analysis of frame by frame through trial and error on sensitivity to not measure wind on the bushes. This could be output to filename and time within the video (videos are captured 10 minutes long).

    2. Take my exported list of png files and string them together somehow into a slide show.

    3. Version 1 here, plus some retroactive capture of clips inside master clips.

    4. Some kind of compression. Again, I have to respect the 3-second max jump.

    Any other options that would be relatively easy to achieve without moving into any other software ? I’m trying to put the heavy lifting on the computer, as staring at videos is not something I’m finding I’ll be able to do for many days.

  • lavc : Use av_gettime_relative()

    lavc : Use av_gettime_relative()

    Whenever av_gettime() is used to measure relative period of time,
    
av_gettime_relative() is prefered as it guarantee monotonic time
    
on supported platforms.
