// The Starboard configuration for a stub implementation designed to be

// --- Filesystem Configuration ----------------------------------------------

// and modification time for files and directories. When this quirk is defined,

// this fact into account in unit tests.

// --- Media Configuration ---------------------------------------------------
// After a seek is triggered, the default behavior is to append video frames
// from the last key frame before the seek time and append audio frames from the
// seek time because usually all audio frames are key frames. On platforms that
// cannot decode video frames without displaying them, this will cause the video
// being played without audio for several seconds after seeking. When the
// following macro is defined, the app will append audio frames start from the
// timestamp that is before the timestamp of the video key frame being appended.

// This quirk has been deprecated in Starboard version 12 or later. Please see
// `configuration_public.md` for more details.
