claincly 2a187cbf56 Disable setting profile/level for API level < 24. 
We have seen devices running on API21/23 fail transcoding because of setting
encoding profile/level.

Some devices (ale-123/nexus 7) on API21 returns ENOSYS (Function not
implemented) when being configured with a profile setting. (although API21
introduced the capability of setting encoding profile)

Some devices (nexus 5) on API23 fails configuration with a specific parameter
set, despite advertising support for it.

Not setting the baseline profile has no effect on encoding, because when not
set, the encoding will pick a suitable profile to use. Since baseline is
the lowest possible profile, the auto-picked value can't be worse than
baseline.

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.
