It seems generally useful to have access to the decoder in
getOutputFormat. We're currently working around lack of access
by using member variables in the concrete audio extension
renderers. In the case of the Ffmpeg extension, holding a
reference to the decoder is preventing it from being garbage
collected when the decoder is released by the base class.

This allows us to enforce the limit because the array can only be
reassigned through reset(byte[]) or reset(byte[], int) (which update
the limit)

The renderers are currently constructing formats that consist of their
input format with added PCM encoding. Such formats are not self-consistent,
and this only works because DefaultAudioSink ignores the rest of the
format if the format has a PCM encoding. It would not work if the sink
implementation checked the MIME type, for example, which wouldn't be a
strange or incorrect thing for it to do.
The more correct approach is to construct a new format that properly
represents the PCM that will be provided to the sink.
This change also renames supportsOutput to supportsFormat, because
AudioSink itself has both an input and an output side, and this method
is actually evaluating support on the input side of the sink.

Previously only pcm encoding were stored in Format,
this was an issue as for audio passthrough and offload
lots of code needs to pass complex format informations
(encoding, sample rate, channel count, gapless metadata)
but could not use Format and each function was taking
each as different parameter.
By allowing Format to contain any encoding, and not only
pcmEncoding, it allows to pass a Format everywhere in ExoPlayer
code that needs a Format.
This patch does not have any functional change. It is only an internal refactor.

Propagate format in supportsOutput
It is needed to know if gapless is needed,
as gapless offload might not be supported.

- It seems conceptually simpler for DefaultExtractorsFactory
- It seems unlikely we'll need to diverge the two. In the case of
workaround flags we can just have them be no-ops in the version
that doesn't need them.

- Show renderers with no tracks in EventLogger track logging
- Log renderer names in EventLogger track logging
- Add useful message to ExoPlaybackException instances (including
renderer name for renderer errors)

This is a necessary step for Decoder implementations to support
audio and video. MediaCodecRenderer.DecoderException is renamed
MediaCodecDecoderException and extends the new DecoderException

The restriction that these classes only work with SimpleDecoders
is unnecessary. An FfmpegVideoRenderer will not be able to use a
SimpleDecoder, because the SimpleDecoder assumption that each input
buffer can be decoded immediately into a corresponding output is
not true for all video codecs that Ffmpeg supports (e.g., H264 does
not have this property). Generalizing SimpleDecoderVideoRenderer to
DecoderVideoRenderer will allow FfmpegVideoRenderer to still use
the base class, without having to use a SimpleDecoder.
This is a preliminary change toward being able to merge a version
of https://github.com/google/ExoPlayer/pull/7079.

The ceilingTimePosition is based on the total number of samples. Binary
search seeking is not possible if this value is unknown.

This check is not needed because the FLAC specification does not
restrict the sample rate value and because the extension reads files
with other sample rates properly.

It could either live in .util or .extractor, but since it's not needed
outside the extractor package in core (and the FLAC extension), and
FlacStreamMetadataTest uses a FLAC asset, it seems preferable to move it
into the extractor package.
PiperOrigin-RevId: 291372032
This makes the format metadata null (instead of an empty Metadata
object) when it is not provided, and is therefore consistent with the
other extractors behavior.

Assuming that a flac stream starts with bytes
['f', 'L', 'a', 'C', 0, 0, 0, 0x22] is not always correct as it could
also start with ['f', 'L', 'a', 'C', 0x80, 0, 0, 0x22]
(see https://xiph.org/flac/format.html#metadata_block_streaminfo).

- Fix FLAC extension build (currently broken due to use of std::array,
but fixed by migrating to NDK r20).
- Move opus and ffmpeg extensions to NDK r20. For ffmpeg, upgrade to
release 4.2 which requires using libswresample and updates to the
build script.

Keeping the ones inside loops, because theoretically they
can be useful there (in practice, for this use case, it's
highly unlikely to make any difference).
