The opus.c file uses ff_celt_freq_range and ff_celt_freq_bands which are
defined in opustab.c. The opus parser needs to include that file to
avoid linker errors when not including the opus encoder/decoder.

In commit 061a0c14bb ("decode: restructure the core decoding code"), the
deprecated avcodec_decode_* APIs were reworked so that they called into the
new avcodec_send_packet / avcodec_receive_frame API. This had the side effect
of prohibiting sending new packets containing data after a drain
packet, but in previous versions of FFmpeg this "worked" and some
applications relied on it.
To restore some compatibility, reset the codec if we receive a new non-drain
packet using the old API after draining has completed. While this does
not give the same behaviour as the old API did, in the majority of cases
it works and it does not require changes to any other part of the decoding
code.

Compilation error "out of range" fixed for armeabi-v7a. Compilation failed
trying to build libvlc.aar for ARM7 android on ubuntu 16.04 host. Error
messages is "Offset out of range". The reason of the error is assembler LDR
directives in function "ff_hevc_transform_luma_4x4_neon_8" need local storage
in range <1k, but no such storage provided.

This should save quite a bit of space if either has been disabled for size reasons.
Could just check if the encoding flag is set during runtime on every single location,
however the overhead of branch misses would somewhat decrease performance.

The existing logic overrides container metadata even in cases where the
container metadata must be trusted (e.g. HDR). The original spec had no
provision for specifying color volume, so many files rely on the
assumption of Rec. 709.
An update to the spec included a 'clv' field for explicitly signaling
that the container should be trusted in an existing bitfield in the
frame header, but the default of 0 from old encoders forces Rec. 709,
which would break any HDR stream. Because there is no place in DNxHR for
specifying a transfer function, DNxHR HDR files must include
container-level color information.
This patch maintains the existing behavior of choosing the 709 over the
601 matrix when container-level information is missing, and allows
container-level information to win if present.

webm usually has invisible superframes merged with normal frames.
(vpxenc muxes them in this form, which is evidence enough that this is
the standard webm packet format. It's rather unclear whether ffmpeg is
even allowed to remux them with split packets.)
The vp9 decoder needs them to be in separate packets for multithreading
to work. Add the BSF to the decoder, so the conversion happens
automatically.
This contains the important part of fa1749dd34, which
was apparently skipped in commit d417e95af7. This restores Libav API
compatibility.
In function process_output_surface(), the return value is 0 on the path
that av_mallocz() returns a NULL pointer. 0 indicates success, which
deviates from the fact. Return "AVERROR(ENOMEM)" instead of "0".
