oa::MediaPlayer

Synchronized playback session over independent audio and video owners. Audio output frames consumed by the device callback are the master clock. Call tick from the engine-owning thread to advance video. Decode and audio callback workers never borrow or submit through Engine. The current frame retains its decoder backing and must obey VideoFrame::mark_consumed before its storage can be recycled.

Public Method Documentation

pub fn play(&mut self) -> Result<()>
Open both tracks paused, with the first video frame decoded. Native video output preserves its GPU backing. Opening requires a compatible Vulkan Video device and an audio output device.
pub fn pause(&mut self) -> Result<()>
Open both tracks paused, with the first video frame decoded. Native video output preserves its GPU backing. Opening requires a compatible Vulkan Video device and an audio output device.
pub fn tick( &mut self, max_frames: u32 ) -> Result<u32>
