  • Revision 427cdf0a41 : Reduce the number of full block SAD calls This commit uses a 6-point 1-step ref

    13 mars 2015, par Jingning Han

    Changed Paths :
     Modify /vp9/encoder/vp9_mcomp.c



    Reduce the number of full block SAD calls

    This commit uses a 6-point 1-step refine motion search in the
    integral projection based full pixel motion estimation, to replace
    the current 9-point search.

    It reduces runtime cost of speed -6 on some noisy clips, e.g.,
    dark720p single thread
    33314 b/f, 40.076 dB, 18231 ms ->
    33307 b/f, 40.067 dB, 17768 ms

    The compression performance for rtc set remains unchanged.

  • 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 :

  • Need to reduce video size for my symfony project since it's taking too much time to upload 300MB+ videos

    18 juin 2020, par manu

    I have tried FFmpeg its showing error "Your FFProbe version is too old and does not support -help option, please upgrade". I have tried few fixes already available in stackoverflow and other sites but it won't work for me. If u know any alternative packages please share. The symfony version am using is 4.4. Now am planning to use symfony/process. This is an API where users can upload their recorded video from mobile app. please share better option
