This test was testing a scenario that never happens in production.
Indeed, in this test, a frame was registered to the
ExternalTextureManager but never rendered on the decoder ouput surface.
This never happens in production because both actions are normally
performed in
PlaybackVideoGraphWrapper.InputVideoSink.handleInputFrame().
This test was also failing on API 31 emulator. As the frame was never
rendered, the timeout to release all registered frames in
ExternalTextureManager was always exceeded. This sometimes caused the
decoder to fail on this emulator because there was no interaction with
the decoder for a long time.
