    lavc/vvc : Detect subpic overlaps at CTU level

    In d5dbcc00d889fb17948b025a468b00ddbea9e058, it was hoped that detection
    
of subpicture overlaps could be performed at the tile level, so as to
    
avoid introducing per-CTU checks. Unfortunately since that patch,
    
fuzzing has indicated there are some structures involving
    
pps_subpic_one_or_more_tiles_slice where tile-level checking is not
    
sufficient.  Performing the check at the CTU level should (touch wood)
    
be the be-all and and-all of this, as CTUs are the lowest common
    
denominator of the picture partitioning.

  • ffmpeg constant frame-rate - same as the source

    13 octobre 2020, par Andrea Vettorino

    I am using ffmpeg to convert a video (to emulate HandBrake). I would like the result to be with constant frame-rate, the same as the source (if the source is constant), otherwise if the source is variable the lowest of the source values (with a minimum of 23.97 and a max of 30).

    &#xA;

    I tried with -filter :

    &#xA;

    ffmpeg -i input.mp4 -filter:v fps=fps=23.98 output.mp4 &#xA;

    &#xA;

    but in this way it would just be constant with a value that I fix.

    &#xA;

    Also, with ffmpeg -re -i input.mp4 output.mp4&#xA;it should be the same as source but again, in case the input is variable it doesn't work.

    &#xA;

    Thank you for your help

    hwcontext_vulkan : fix uploading and downloading from/to flipped images

    We want to copy the lowest amount of bytes per line, but while the buffer
    
stride is sanitized, the src/dst stride can be negative, and negative numbers
    
of bytes do not make a lot of sense.
