Issue: google/ExoPlayer#9744

We do not rely on the payload type to determine the sample MIME type, we depend
on the SDP message, so it's worthless checking the payload type.

After removing the line, a server can use payload type 35 (an unassigned
payload type) for H264; while normally H264 requires payload type >= 96).

Previously, transformation_matrix was incorrectly applied to
texture sampling coordinates, which led to transformations
seemingly moving in the opposite position, and an undesirable
GL_CLAMP_TO_EDGE behavior when sampling outside the edge of
the texture.

Allowing duplicate groups caused some other code working with the
array to use reference equality comparison. This is error-prone,
easily forgotten (e.g. when using the TrackGroups in a map) and
causes bugs when TrackGroups are serialized to disk or to another
process.

All TrackGroups created by ExoPlayer are already unique and custom
code creating TrackGroupArrays with identical groups can easily
distringuish them by adding an id to each group.

It seems fine to remove the documentation about the WebM case now we are only supporting unfragmented MP4, so that new users coming to this API aren't confused about how to set the container MIME type.

This allows to give TrackGroups an identifier. The underlying goal is
to provide a way to make otherwise identical TrackGroups
distinguishable.

Also set this id in all internal sources that may produce identical
TrackGroups in certain edge cases.

Allows a transformation matrix to be input into Transformer,
to apply vertex transformations like cropping, rotation,
and other transformations built into android.graphics.Matrix.

Not building out into a VertexTransformation class yet, as
that class structure wouldn't make sense until we can modify
resolution, per TODOs.

This will remove the need to implement compat code handling very old API
versions where some symbols are not available, and it reduces the burden of
dealing with media framework issues around concurrent codec usage that are
worse on older API versions. Top apps that we've surveyed as potential users
for transformer library features are using API 21 or later.

Sometimes the empty end of stream buffer has a non-zero
data limit. Calling flip first, resets the limit to the
position which is zero in these cases.

The test extracts and decodes the first video frame in the test media, renders it to the frame editor's input surface and then processes data. It then reads back the output from the frame editor, converts it to a bitmap and then compares that with a 'golden' bitmap (which is just the same as the test media's first video frame).

*** Original commit ***

Remove usage of @ForOverride.

Fixes the gradle compilation failures.

Gradle dependencies need revising if we want to be using this, as
checkerframework is ahead of their latest version, such that we
can't compile.

Currently we prefer technical preferences set in the Parameters over
content preferences implied by the media. It proably makes more
sense in the opposite order to avoid the situation where a
non-default track (e.g. commentary) is selected just because it
better matches some technical criteria.

Also add comments explaining the track selection logic stages.

When the input is not a slow motion video, then flattening should do
nothing, so there is no need to re-encode audio.

And also tweak existing role flag logic to strictly prefer perfect
matches over partial matches.

Caveat: Video role flags only supported for fixed track selections
(same issue as Issue: google/ExoPlayer#9519).

This allows to check if the media metrics service is available outside
the actual constructor and to fail gracefully if it is missing.

- This format is passed to the PassthroughPipeline, which doesn't use
  any decoder.
- In most other cases where it is used, it is not relevant that this
  format will be or has been passed to the decoder. What's relevant is
  that it is the format of the input.

We need the filename of the output videos to be predictable, because
MobileHarness requires the exact filename to pull the file.

Deprecates setContext() and moves the required Context arg into the constructor.

This way, the parameter can later be final and non-null, per the comment at:
http://go/https://github.com/androidx/media/commit/79f03bb1355b7e370991a1aafd580324d22e070e/depot/google3/third_party/java_src/android_libs/media/libraries/transformer/src/main/java/androidx/media3/transformer/TranscodingTransformer.java?left=s19&right=r12#97L

Also, fixes setOutputMimeType_unsupportedMimeType_throws by providing a context
in the builder, and updating the FrameworkMuxer#supportsOutputMimeType to catch
IllegalArgumentExceptions thrown by FrameworkMuxer#mimeTypeToMuxerOutputFormat.

This change moves methods that are the same in
`TransformerAudioRenderer` and `TransformerVideoRenderer` to
`TransformerBaseRenderer`.

This inheritance is really confusing because ExoPlayerImpl is not
a full Player interface implementation. It also claims to be an
ExoPlayer implementation in the Javadoc which isn't true in its
current state.

Removing the inheritance also allows to clean up some unused methods.

This is documented on the setter already, but it seems to make sense to do this in the constructor as well for clarity.

Before this change ExpPlayerImplInternal dropped a change of the playing period when a change in the timeline occurred that actually changed the playing period but we don't want to update the period queue. This logic also dropped the update of a skipped server side inserted preroll ad for which we want the periodQueue to 'seek' to the stream position after the preroll ad and trigger a SKIP discontinuity.

This change now introduces an exception so that a skipped SSI ad is still causing an update in the period queue which leads to a 'seek' and a discontinuity of type SKIP.
