  • avcodec/mpeg4videoenc : Fix data race when using AC prediction

    avcodec/mpeg4videoenc : Fix data race when using AC prediction

    The check for whether we can use the fast path to process
    
AC coefficients used the qscale value belonging to a different
    
slice ; this worked in practice, because the predicted AC values
    
are zero in this case, so it does not matter whether we use
    
the fast or the slow path.
    

    Fix this by checking for first_slice_line instead. This fixes all
    
the races in the encoding part of the vsynth*-mpeg4-thread tests
    
(and fixes them if no frame threading is in use for the decoding part).
    

    (The left prediction check may use data from a different slice, too,
    
but said slice is always processed by the same thread, so that no race
    
can happen. Given that out-of-slice AC values are zero, it does not
    
matter whether we use the fast path or the slow path either.)

    fftools/resources/resman : Don't alloc ResourceManager, fix race

    The resman_ctx pointer was accessed outside of its guarding
    
mutex.
    

    Also make the ResourceManager static.

  • lavc/vvc : Fix race condition for MVs cropped to subpic

    30 décembre 2024, par Frank Plowman
    lavc/vvc : Fix race condition for MVs cropped to subpic

    When the current subpicture has sps_subpic_treated_as_pic_flag equal to
    
1, motion vectors are cropped such that they cannot point to other
    
subpictures.  This was accounted for in the prediction logic, but not
    
in pred_get_y, which is used by the scheduling logic to determine which
    
parts of the reference pictures must have been reconstructed before
    
inter prediction of a subsequent frame may begin.  Consequently, where a
    
motion vector pointed to a location significantly above the current
    
subpicture, there was the possibility of a race condition.  Patch fixes
    
this by cropping the motion vector to the current subpicture in
    
pred_get_y.
