2020-05-20avfilter/vf_dedot: Fix leak of AVFrame if making it writable failsAndreas Rheinhardt
Even in this scenario, the frame still contains references to data that won't be freed if the frame isn't unreferenced. And the AVFrame itself will leak, too. Fixes Coverity issue #1441422.

2020-05-20avfilter/vf_paletteuse: Fix potential double-free of AVFrameAndreas Rheinhardt
apply_palette() would free an AVFrame given to it only via an AVFrame * (and not via AVFrame **) in three of its four exists (namely in the normal path and in two error paths). So upon error the caller has no way to know whether the frame has already been freed or not; load_apply_palette(), the only caller, opted to free the frame in this scenario. This commit changes this by making apply_palette not freeing the frame at all, which is left to load_apply_palette(). Fixes Coverity issue #1452434.

2020-05-20avfilter/vf_unsharp: Don't dereference NULLAndreas Rheinhardt
The unsharp filter uses an array of arrays of uint32_t, each of which is separately allocated. These arrays also need to freed separately; but before doing so, one needs to check whether the array of arrays has actually been allocated, otherwise one would dereference a NULL pointer. This fixes #8408. Furthermore, the array of arrays needs to be zero-initialized so that no uninitialized pointer will be freed in case an allocation of one of the individual arrays fails.

2019-07-03libavfilter/vf_colorspace.c: fix demarcation point of gamma linearize functionYonglin Luo
The linearize function (usually refered to EOTF) is the inverse of delinearize function (usually referred to OETF). Demarcation point of EOTF should be beta*delta, but the actual value used now in the source code is beta. For ITU Rec.709, they are 0.081 (0.018*4.5) and 0.018 respectively (beta = 0.018 and delta = 4.5), and they correspond to pixel value 5 and 21 for an 8-bit image. Linearized result of pixel within that range (5-21) will be different, but this commit will make linearize function of the filter more accurate in the mathematical sense.
