public int getHardwareClockDiscontinuityCount() {

Gets count of hardware clock discontinuities.
<p>When this value stays the same, vs. a value in a previously reported {@link GnssClock}, it
can be safely assumed that the {@code TimeNanos} value has been derived from a clock that has
been running continuously - e.g. a single continuously powered crystal oscillator, and thus
the {@code (FullBiasNanos + BiasNanos)} offset can be modelled with traditional clock bias
& drift models.
<p>Each time this value changes, vs. the value in a previously reported {@link GnssClock},
that suggests the hardware clock may have experienced a discontinuity (e.g. a power cycle or
other anomaly), so that any assumptions about modelling a smoothly changing
{@code (FullBiasNanos + BiasNanos)} offset, and a smoothly growing {@code (TimeNanos)}
between this and the previously reported {@code GnssClock}, should be reset.

The id3v2 spec doesn't specify the syntax of the genre tag very precisely, so
some assumptions are made. Using one possible interpretation of the id3v2
spec, this method converts an id3 genre tag string to a human readable string,
as follows:
- if the first character of the tag is a digit, the entire tag is assumed to
be an id3v1 numeric genre code. If the tag does not parse to a number, or
the number is outside the range of defined standard genres, it is ignored.
- if the tag does not start with a digit, it is assumed to be an id3v2 style
tag consisting of one or more genres, with each genre being either a parenthesized
integer referring to an id3v1 numeric genre code, the special indicators "(CR)" or
"(RX)" (for "Cover" or "Remix", respectively), or a custom genre string. When
a custom genre string is encountered, it is assumed to continue until the end
of the tag, unless it starts with "((" in which case it is assumed to continue
until the next close-parenthesis or the end of the tag. Any parse error in the tag
causes it to be ignored.
The human-readable genre string is not localized, and uses the English genre names
from the spec.

This method is similar to {@link #getScaledFrameAtTime(long, int, int, int, BitmapParams)}
except that the device will choose the actual {@link Bitmap.Config} to use.
@param timeUs The time position in microseconds where the frame will be retrieved.
When retrieving the frame at the given time position, there is no
guarantee that the data source has a frame located at the position.
When this happens, a frame nearby will be returned. If timeUs is
negative, time position and option will ignored, and any frame
that the implementation considers as representative may be returned.
@param option a hint on how the frame is found. Use
{@link #OPTION_PREVIOUS_SYNC} if one wants to retrieve a sync frame
that has a timestamp earlier than or the same as timeUs. Use
{@link #OPTION_NEXT_SYNC} if one wants to retrieve a sync frame
that has a timestamp later than or the same as timeUs. Use

that has a timestamp closest to or the same as timeUs. Use
{@link #OPTION_CLOSEST} if one wants to retrieve a frame that may
or may not be a sync frame but is closest to or the same as timeUs.
{@link #OPTION_CLOSEST} often has larger performance overhead compared

Retrieve a video frame near a given timestamp scaled to a desired size.
Call this method after setDataSource(). This method finds a representative
frame close to the given time position by considering the given option
if possible, and returns it as a bitmap with same aspect ratio as the source
while scaling it so that it fits into the desired size of dst_width by dst_height.
This is useful for generating a thumbnail for an input data source or just to
obtain a scaled frame at the given time position.
@param timeUs The time position in microseconds where the frame will be retrieved.
When retrieving the frame at the given time position, there is no
guarantee that the data source has a frame located at the position.
When this happens, a frame nearby will be returned. If timeUs is

Read the document's DTD. Although this parser is non-validating, the DTD
must be parsed to capture entity values and default attribute values.

Reads an external ID of one of these two forms:
SYSTEM "quoted system name"
PUBLIC "quoted public id" "quoted system name"
If the system name is not required, this also supports lone public IDs of
this form:
PUBLIC "quoted public id"
Returns true if any ID was read.

Read an element content spec. This is a regular expression-like pattern
of names or other content specs. The following operators are supported:
sequence: (a,b,c)
choice: (a|b|c)
optional: a?
one or more: a+
any number: a*
The special name '#PCDATA' is permitted but only if it is the first
element of the first group:
(#PCDATA|a|b)
The top-level element must be either a choice, a sequence, or one of the
special names EMPTY and ANY.

Reads an attribute list declaration such as the following:
<!ATTLIST foo
bar CDATA #IMPLIED
quux (a|b|c) "c"
baz NOTATION (a|b|c) #FIXED "c">
Each attribute has a name, type and default.
Types are one of the built-in types (CDATA, ID, IDREF, IDREFS, ENTITY,
ENTITIES, NMTOKEN, or NMTOKENS), an enumerated type "(list|of|options)"
or NOTATION followed by an enumerated type.
The default is either #REQUIRED, #IMPLIED, #FIXED, a quoted value, or
#FIXED with a quoted value.
