  • Revision a00dad39bd : No arf right before real scene cut. To reduce pulsing we now allow an arf just

    3 janvier 2014, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_firstpass.c



    No arf right before real scene cut.

    To reduce pulsing we now allow an arf just before forced key frames
    and at the end of a clip or section (which may be stitched to
    another clip or section). However, this does not make sense for
    key frames arising from real scene cuts.

    Change from original patch reflects other recent changes in regard
    to alignment of gf/arf and kf groups.

  • file input from http (url) in melt plugin

    26 décembre 2017, par Anuj TBE

    I’m using MELT plugin for generating crossfade animation using series of images.

    I found the corssfade animation script from here.

    and the script is

    melt -verbose \
    
-profile atsc_720p_25 \
    
001.png out=50 \
    
002.png out=75 -mix 25 -mixer luma \
    
003.png out=75 -mix 25 -mixer luma \
    
004.png out=75 -mix 25 -mixer luma \
    
005.png out=75 -mix 25 -mixer luma \
    
-consumer avformat:output.mp4 vcodec=libx264 an=1

    But instead of providing file from local path, I want to use http url like

    melt -verbose \
    
-profile atsc_720p_25 \
    
http://example.com/image1.jpg out=50 \
    
http://example.com/image2.jpg out=75 -mix 25 -mixer luma \
    
http://example.com/image3.jpg out=75 -mix 25 -mixer luma \
    
http://example.com/image4.jpg out=75 -mix 25 -mixer luma \
    
http://example.com/image5.jpg out=75 -mix 25 -mixer luma \
    
-consumer avformat:output.mp4 vcodec=libx264 an=1

    But it gives

    No LADSPA plugins were found!
    

    
Check your LADSPA_PATH environment variable.

    and full output is

    No LADSPA plugins were found!
    

    
Check your LADSPA_PATH environment variable.

    Mais pour l’ajout là c’est bizarre on voit pas le fond, c’est un peu nul, en tout cas pour cette couleur.
    Peut-être l’inverse aussi, le retrait est plus gros que l’ajout : ça ne va pas. C’est le retrait qui devrait être en mini+link (très peu mis en avant), et l’ajout en normal, ni link, ni peut-être mini non plus.
