  • ffmpeg - Retain video quality/encoding whilst trimming [on hold]

    26 janvier 2018, par adam763

    I have an AVI file, which I trim down to the last 4 seconds using the following code via Windows batch :

    ffmpeg -sseof -4 -i Videoclip1.avi -b 404k 0000000001.avi

    However, the quality degrades...

    But my MAIN ISSUE is the following...

    The video’s encoding also changes.

    The original plays fine in my software, but the new video becomes an ’unsupported format’.

    Although the new video will play in Media Player/VLC, I require it to work in my own software.

    Is there a setting I need to change, or something I can add to my batch file to retain the original quality/encoding ?

    Thanks in advance.

  • Can ffmpeg log a output of histogram and wavetransform ?

    5 février 2018, par jay

    ffmpeg has an option of showing a color histogram and a wavetransform which is from sound data on a screen.

    I want to collect them as text form pushing into a log file and later can check with linux text parser tools.

    For example, Assuming some of videos has a period of black screen as it plays.
    Then it is easy to find out that ’when does video has a period of black ?’ or ’which video file has a period of black ?’ by YCbCr histogram log.

    is it possible ? I have looked ffmpeg document but couldn’t find it.

  • FFmpeg scale 720*1080 video to 720*404, it not effect, it play as 279 × 404,and use ffmpeg -i it shows 720*404

    16 mars 2018, par yue guan

    FFmpeg scale 720*1080 video to 720*404, it not effect, it plays as 279 × 404, and use cmd ffmpeg -i scaled.mp4 it shows 720*404.
    Then I use cmd ffmpeg -i scaled.mp4 -y -f image2 -ss 1 -vframes 1 ./xx.jpg to get the thumbnail, but I got the size is 720*404.
    Why ?
    and How can I capture the thumbnail of the video as 279*404 ?
    and How can I scale the video as the size what I defined ?
