hschlueter e4605583bc Check targetSdkVersion for frame dropping workaround. 
Based on
https://developer.android.com/reference/android/media/MediaCodec#using-an-output-surface,
frame dropping behaviour depends on the target SDK version.
After this change transformer will only use
MediaFormat#KEY_ALLOW_FRAME_DROP if both the target and system SDK
version are at least 29 and default to its pre 29 behaviour where each
decoder output frame must be processed before a new one is rendered
to prevent frame dropping otherwise.

Also remove deprecated Transformer.Builder constructor without a
context and the context setter.

Transformer module

Provides functionality for transforming media files.

Getting the module

The easiest way to get the module is to add it as a gradle dependency:

implementation 'com.google.android.exoplayer:exoplayer-transformer:2.X.X'

where 2.X.X is the version, which must match the version of the other media modules being used.

Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.

Using the module

Use of the Transformer module is documented in the developer guide.
