Frame cache compensates for the fluctuation in frame processing times. Imagine a frame takes 10ms to process, and the interval between two frames is 33ms. The third frame took 40ms to process. If we don't have frame cache: - Process frame 1, ready after 10ms, starts playback, now t=0 ms - Start processing frame 2, ready at t=10ms, - Release frame 2 at t=33ms - We start processing the third frame at t=33ms - The third frame is due presentation at t=66ms - But frame 3 is available at t=73ms, late If we have a frame cache of say 3 frams, - Process frame 1, ready after 10ms, starts playback, now t=0 ms - Start processing frame 2, ready at t=10ms - Start processing frame 3, ready at t=50ms - Release frame 2 at t=33ms - Start frame 4, ready at t=60ms - Frame 3 is due presentation at t=66ms - Frame 3 isn't late PiperOrigin-RevId: 501869948
Effect module
Provides functionality for applying effects to video frames.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-effect:1.X.X'
where 1.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.
