In the case of replace stream media item transition, it is important that dynamic scheduling does not set the next work task later than the transition boundary.

AV1 input buffers contain multiple compressed pictures.
Enable skipping only the last showable frame, while leaving
any reference pictures to be decoded later, as part of
the next decoder input buffer.
Partial skipping of AV1 input buffer is only applied when:
* fewer than 8 OBUs are delayed
* there's likely to be enough capacity in the decoder input buffer
for the next frame

Parsing AV1 bitstreams allows us to identify frames that are
not used as reference, and improve seeking or frame dropping
behavior.
The AV1 bitstream format is relatively quick to parse

From the `sampleMimeType`, we can know whether the media item contains video data, image data, and audio data. This is done for input media items, and the output media item.

- It's never used and handling multi-threading is costly.
- If the VideoCompositor and the VideoFrameProcessors use separate
threads and the same GlObjectsProvider, the GlObjectsProvider is
accessed from multiple threads. This class doesn't seem designed for
multi-threading.

When a timeline change occurs, the `AdTagLoader` will post an adLoad timeout task if currently waiting for an ad to load. Once sdk calls `loadAd`, any pending timeout tasks are removed. If the timeout occurs, the ad group is canceled and content will resume.
If the SDK proceeded to resume content without calling `loadAd`, then any pending timeout tasks should be removed or else a future ad group may error due to a previous timeout task.

Seeking will reset media periods following the current playing period. This includes resetting any current pre-warming media periods. Therefore while seeking, any current pre-warming should be disabled and reset.

When sample batching is disabled, copying of the ByteBuffer data
is not necessary as samples are written as they arrive.
Copying of the BufferInfo is necessary because the info is needed
for writing the moov atom.
The input ByteBuffer can be in little endian order, or have its
position set. AnnexBUtils now ensures big endian order before
inspecting bytes, and supports reading from a non-zero position.
This change reduces the amount of memory allocations by Mp4Muxer
in its default configuration

Previously, the codec names for the input were collected from `Format.codecs` which return the RFC 6381 string not the codec name used. This was changed to retain the decoder name from `ProcessedInput` instead.

This will allow the listeners who are interested in the `SeekMap` to get informed once the period has done the preparation.

MediaCodecVideoRenderer is becoming unwieldy with the numerous constructors and optional settings. This refactors MediaCodecVideoRenderer to use a builder pattern for simplicity.

It includes entering a custom text and setting the alpha scale. When the effect is applied, it shows the text in the center of the screen. A following change will include changing the color of the text.

Also updated DefaultVideoFrameProcessor to create GlShaderPrograms with the working ColorInfo rather than the output ColorInfo.

This means we need convert some of the assertions in
ClippingMediaPeriod to contrain the output value to clipped
range instead, because unseekable media will return zero
as a start and seek position in all cases.

Most of the values for the output `MediaItemInfo` will be retained from the `ExportResult`, so it's now passed to `onExportSuccess` and `onExportError` directly. For now, the duration of the ouput is recorded for metrics, and more values will be added in the following CLs.

This is necessary for prewarming. With prewarming, in a sequence of 2
videos, the second renderer is enabled before the first one is disabled,
and decode-only frames should be skipped before the second renderer is
started. The problem is that the second renderer will forward frames to
a BufferingVideoSink before it is started, which will delay the frame
handling and therefore not skip the frame before the renderer is
started.
