[FFmpeg-devel] [PATCH] configure: Make nvenc select atsc_a53

[Andreas Rheinhardt]

It is the common code (that is compiled depending upon CONFIG_NVENC)
that uses ff_alloc_a53_sei(), so it is natural to make nvenc itself
select atsc_a53.
This fixes compilation errors in case nvenc is enabled
(e.g. autodected) with both nvenc-based encoders disabled.
(This works in case of static linking (nothing pulls in nvenc.o),
but it fails with shared builds.)

It would also be obviously desirable to disable nvenc if it is
not needed if it is only autodetected and not explicitly enabled.
Maybe it should even be unconditionally disabled if unused.

There is btw a similar issue with crystalhd: If it is enabled,
yet all the decoders are disabled and if one uses -O0, then
the unused functions in crystalhd.c are not stripped away and
linking errors ensue.
