  • FFMPEG/AVCONV Video flipping is taking long time, How can we reduce the process time ?

    10 juillet 2014, par Prasanth P

    I am trying to flip video using FFMPEG/AVCONV on Ubuntu. When it flips 1 minute video, it takes 12 to 40 seconds for processing and conversion.

    ffmpeg is deprecated and avconv is being using instead.

    Video file size : 7mb, Duration : 1 minute

    avconv -i 1_1.mp4 -c:v libx264 -c:a copy -vf "vflip" conv.mp4

    and the result is :
