  • detecting if video is slow motion with ffmpeg or ffprobe

    29 août 2019, par Ahmet Cetin

    I have big number of videos to process and need to mark them if the video is slow motion or not.

    Is there a way to detect if a video file is slow motion or normal speed using ffmpeg or ffprobe, or any other linux command line app or npm library ? Any ideas ?

  • How to filter motion vectors ?

    2 août 2019, par vdletg

    My video is very noisy temporally. The video was taken under low light conditions at a high frame rate.

    Currently I’ve tried

    ffplay -flags2 +export_mvs -i test.mp4 -vf edgedetect=low=0.05:high=0.17,hqdn3d=4.0:3.0:6.0:4.5,codecview=mv=pf+bf+bb,"lutyuv=y='if(lt(val,19),0,val)'

    The motion vectors are tracking noise as in the near dark areas the vectors varying greatly in magnitude and angle.

    How do I decimate or filter the display motion vectors based on magnitude and/or location ?

  • Where is the initialization of motion vector in source code ?

    3 novembre 2019, par Alex

    In IMPROVED RATE CONTROL AND MOTION ESTIMATION FOR H.264 ENCODER this paper introduce initialize with extra motion vector. I would like to try some other initialization methods, but I can not find where the initialization code realized.

    



    In encoder/me.c I can only find the function which uses mvc. But for where mv is initialized, I am get confused with the code.
