  • Correct recording time of the first frame of a video

    27 juillet 2017, par Vítor Cézar

    How do I get the correct time of the first frame recorded on a video ? I executed the command

    ffprobe -v error -show_streams [file_path]

    and got these values of timecode and creation time for the first stream :

    TAG:creation_time=2017-07-26T16:48:10.000000Z
    
TAG:language=eng
    
TAG:handler_name=   GoPro AVC
    
TAG:encoder=GoPro AVC encoder
    
TAG:timecode=17:21:54:28

    The problem is that the video started being recorded on 16:48:11:504 and neither timecode nor creation time shows this value. If possible I need the precision on milliseconds.

  • convert images to video with differing time ranges

    11 juin 2013, par FaultyJuggler

    I have images coming in at random times labeled with their epoch time they were taken. I want to create a video that shows their real time creation in order. FFMPEG (far as I can tell) only allows you to set the framerate.

    For now I'm looking at creating a video file per image that is as long as the gap between the current image and the next image's timestamp, then concatenating all videos together after.

    Is there a better way to do this ?

  • Estimate time of transcoding video FFMPEG [on hold]

    9 mars 2019, par Anh Vo Nguyen Nhat

    Currently, I want to assign a video transcoding task to a computer in my distributed network. The computer are heterogeneous, so I have to check whether that computing can handle the task fast enough (during a specified deadline). My approach for this is to run many experiments and then based on the statistics I will try to estimate the time when running another task.

    I am trying to predict beforehand the time it takes when transcoding a video (e.g. transcoding 1920x1080 H264 video to 1280x720 VP9) using FFMPEG tool.
    I have used the following features to build a simple neural network to predict the time :
    - Video Resolution (Input + Output)
    - Video Duration
    - Video Codec (Input + Output)
    - Video Bitrate
    - Video Framerate
    - Number of B, I, P frames

    However, the result is not really promising. I want to ask if there is any other way to estimate/predict the time it takes when transcoding a video ? Are there any other features beside the listed that affects the transcoding time ?
