andrewlewis dd83eca7d4 Add support for experimenting with HDR 
- Add a checkbox in the demo app to enable experimental HDR editing.
- Add an `experimental_` method to `TransformationRequest` to enable HDR editing.
- Add fragment/vertex shaders for the experimental HDR pipeline. The main difference compared to the existing shaders is that we sample from the decoder in YUV rather than RGB (because the YUV -> RGB conversion in the graphics driver is not precisely defined, so we need to do this to get consistent results), which requires the use of ES 3, and then do a crude YUV -> RGB conversion in the shader (ignoring the input color primaries for now).
- When HDR editing is enabled, we force using `FrameEditor` (no passthrough) to avoid the need to select another edit operation, and use the new shaders. The `EGLContext` and `EGLSurface` also need to be set up differently for this path.

Demos

This directory contains apps that demonstrate how to use Android media modules, like ExoPlayer. Browse the individual demos and their READMEs to learn more.

Running a demo

From Android Studio

  • File -> New -> Import Project -> Specify the root media folder.
  • Choose the demo from the run configuration dropdown list.
  • Click Run.

Using gradle from the command line:

  • Open a Terminal window at the root media folder.
  • Run ./gradlew projects to show all projects. Demo projects start with demo.
  • Run ./gradlew :<demo name>:tasks to view the list of available tasks for the demo project. Choose an install option from the Install tasks section.
  • Run ./gradlew :<demo name>:<install task>.

For example, ./gradlew :demo:installNoDecoderExtensionsDebug installs the ExoPlayer demo app in debug mode with no optional modules.
