This feature is mostly only used by NLE software, and is

8e7bea6dc6 configure: Improve requesting specific features
Before this patch trying to enable only https by issuing

    --disable-protocols --enable-protocol=https --enable-gnutls

does not enable https, and

    --disable-all --enable-protocols

does not enable libavformat and the protocols component.

Now the default-enabled options are set after the explicitly
disabled/enabled options are evaluated.

If an explicitly enabled option cannot be enabled configure
will fail printing an error message.

472d488ebc libkvazaar: Set frame rate as a rational number
Updates libkvazaar to pass the exact frame rate to Kvazaar by setting
the numerator and denominator separately instead of a single floating
point number. The exact frame rate is needed for writing timing info to
the bitstream.

Requires Kvazaar version 0.8.1.

09f4822e4e flvdec: perform duration search just once
When loading a truncated flv file, it would previously try to do a seek to

repeated seek attempts are cripple the reading performance.

b06cb15b9d dca: fix misaligned access in ff_dca_convert_bitstream
The function is used on unaligned buffers (such as those provided
by AVPacket), accessing them as uint16_t causes SIGBUS crashes on
architectures like SPARC.

This fixes ubsan runtime error: load of misaligned address for type
'const uint16_t', which requires 2 byte alignment

c59fec783d nvenc: generate dts properly
When there is a non-zero decoding delay due to reordering, the first dts
should be lower than the first pts (since the first packet fed to the
decoder does not produce any output).

Use the same scheme used in mpegvideo_enc (which comes from x264
originally) -- wait for first two timestamps and extrapolate linearly to
the past to produce the first dts value.

9d36cab4c0 nvenc: fix encoding with B-frames
When B-frames are enabled and the encoder returns success, all currently
pending buffers immediately become valid and can be returned to the
caller. We can only return one packet at a time, so all the other
pending buffers should be transferred to a new 'ready' fifo, from where
they can be returned in subsequent calls (in which the encoder does not
produce any new output). This bug was hidden by the incorrect testing of
the encoder return value (the return value was overwritten before it was
tested).

Use two separate functions, depending on whether VFP/NEON is available.

This is set to require armv5te - it uses blx, which is only available
since armv5t, but we don't have a separate configure item for that.
(It also uses ldrd, which requires armv5te, but this could be avoided
if necessary.)
