A delay buffer delayed all the frames except the first one, to open the scrcpy window immediately and get a picture. Make this feature optional, so that the delay buffer might also be used for audio (especially for simulating a high delay for debugging). PR #3757 <https://github.com/Genymobile/scrcpy/pull/3757>
