  • ffmpeg and timecode from movie metadata

    17 décembre 2015, par T4ng10r

    I want to add to movie made by digital camcorder timecode. This timecodes are visible during playback in camera, some tool to extract and visualize EXIF metadata also display them.

    I made few attempts to configure ffmpeg, but only succeed in adding CURRENT PC time, not time from file.

    ffmpeg -y -i S1480002.MP4 -vf "drawtext=fontfile=arial.ttf :expansion=normal: text=%{metadata\\:creation_time}: \ x=(w-tw)/2: y=h-(2*lh): fontcolor=white@0.8" output.mp4

    I need to extract creation time from input file metadata. ffprobe display this time, but ffmpeg don’t.

  • How to check if video have visually corrupted frames ?

    1er février, par B Lolo

    I'm using ffmpeg to convert and analyze video, mostly avi to mkv. Sometimes video that I work on have one frame corrupted in random place, , it looks like :

    



    Digital scramble

    



    How to check if frame is visually corrupted in ffmpeg ?

    



    It's not file corruption (not byte corruption), I know that because this video artifact is present in source file, it's just visual corruption.

    



    This command line gives error free result : 
 ffmpeg -i myinput.avi params out.mkv 2> error_log.txt

    



    How to find if similar pattern is on any more frames in video file ? Can something from signalstats could be helpful ?
