Previously, FrameProcessor never had the usecase in which the output surface is replaced, while previewing introduced this usecase. When switching output surfaces, we need to destroy the EGL Surface linked to the surface that is being swapped out, because an EGL surface is linked to the EGL display (which is not destroyed even when releasing FrameProcessor). A GL exception will be thrown in the following scenario if we don't destroy the EGL surface: 1. Creates a Surface, the surface is identified by address 0x11 2. Sets Surface(0x11) on FrameProcessor. Eventually an EGL surface is created to wrap Surface(0x11) 3. Release FrameProcess, this releases the EGL context 4. Instantiate a new FrameProcessor, sets Surface(0x11) as the output 5. When FrameProcessor creates an EGL surface to wrap Surface(0x11), GL throws an exception, becasue Surface(0x11) has previouly been connected to an EGL surface. PiperOrigin-RevId: 489590072
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.
