hwcontext_opencl: DRM to OpenCL mapping for ARM
...
Using cl_arm_import_memory. Unfortunately, despite this not being a
standard extension, the function clImportMemoryARM() is not accessible
via clGetExtensionFunctionAddressForPlatform(). This means that it has
to be linked directly to the ARM OpenCL binary, so making a portable
binary is not possible as it is with all other mapping extensions.

doc: Add FAQs about running in background (rev 2)
...
Add two FAQs about running FFmpeg in the background.
The first explains the use of the -nostdin option in
a straightforward way. Text revised based on review.
The second FAQ starts from a confusing error message,
and leads to the solution, use of the -nostdin option.
The purpose of the second FAQ is to attract web searches
from people having the problem, and offer them a solution.
Add an anchor to the Main Options section of the ffmpeg
documentation, so that the FAQs can link directly there.

avformat/mov: Increment stsd_count while processing stsd data; avoids leaks.
...
In the event of ff_mov_read_stsd_entries() failure, sc->stsd_count
is not updated, even if the function allocates extradata memory.
Instead update the sc->stsd_count as entries are parsed so that
mov_read_close() can do the right thing.

Fix undefined shift on assumed 8-bit input.
...
decode_user_data() attempts to create an integer |build|
value with 8 bits of spacing for 3 components. However
each component is an int32_t, so shifting each component
is undefined for values outside of the 8 bit range.
This patch simply clamps input to 8-bits per component
and prints out a warning that the values were clamped.
