  • FFMPEG control delay and looping for generating APNG

    24 septembre 2020, par fmw42

    I have a (random selection) of JPG images that I want to use to make into an APNG animation using ffmpeg (to test the process). They are all the same dimensions (256x256). But I cannot seem to get the correct syntax to control the frame delay and loop control (to loop forever). Is it possible to set these parameters using ffmpeg when creating an APNG from a sequence of images ? If so, can someone provide the proper syntax and/or show an example command ? I have searched the ffmpeg documentation and cannot seem to find relevant syntax.

    


    I can do the following, but it will not accept -delay nor -loop. I use Imagemagick to pipe in the images.

    


    This works, but does not loop, and runs very fast.

    


    magick lena.jpg mandril3.jpg monet2.jpg zelda1.jpg PNG:- | ffmpeg -i - x.apng


    

    


    This gives errors about delay and/or loop :

    


    magick lena.jpg mandril3.jpg monet2.jpg zelda1.jpg PNG:- | ffmpeg -i - -delay 1000 -loop -1 x.apng


    

    


    I am also curious to know if it is possible to specify a sequence of images directly in ffmpeg as input without using ImageMagick.

    


    Sorry, I am a relative novice with ffmpeg. I am using ffmpeg 4.2.1.

    avcodec/dynamic_hdr_vivid : fix base_enable_flag control

    The base_enable_flag is parallel to three_Spline_enable_flag. The
    
typesetting of the specification is very misleading.

  • avformat/rtsp : correctly set media control uri with mpegts

    11 octobre 2020, par tpol
    avformat/rtsp : correctly set media control uri with mpegts

    Fixes #1941
    

    Currently the media control uri is not correctly assigned when mpegts is
    
signalled in the media description.
    

    The code checks whether at least one AVStream has been setup before
    
assigning to the media's uri. With mpegts the AVStreams are setup when
    
parsing packets and so the media's uri is skipped. This is fixed by
    
using rt->nb_rtsp_streams in the check which counts all medias in the
    
sdp.
