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 #840
This commit updates the documentation of av_read_frame() to match its
actual behaviour in several ways:
1. On success, av_read_frame() always returns refcounted packets.
2. It can handle uninitialized packets.
3. On error, it always returns clean packets.
This will allow callers to not initialize
av_read_frame() can handle uninitialized input packets and it already
returns clean packets on error.

I'm sorry not to reply in time.
The performance of this C code is about 10% better than the existing C code.
It will have a bigger improvement after X86 SIMD optimizations.

It performs HDR(High Dynamic Range) to SDR(Standard Dynamic Range) conversion
with tone-mapping. It only supports HDR10 as input temporarily.
An example command to use this filter with vaapi codecs:

vaapi \
