1# Media Subsystem Changelog 2 3## cl.media.1 Change in Screenshot API Called by the System Screen Recording Application 4 5**Access Level** 6 7Other 8 9**Reason for Change** 10 11At the end of the system screen recording, a screenshot API provided by the window module will be called to generate a thumbnail of the screen, which will then trigger a screenshot event. This event can interfere with listeners of third-party applications if these applications have subscribed to screenshot events through the window module. 12 13To mitigate this problem, the window module has introduced a new screenshot API designated for the system screen recording application. This way, third-party applications will no longer capture the screenshot events generated by system screen recording application. 14 15**Impact of the Change** 16 17This change does not require application adaptation. 18 19Before change: When system screen recording ends, third-party applications receive a callback event if they have subscribed to screenshot events through the window module. 20 21After change: When system screen recording ends, third-party applications do not receive a callback event if they have subscribed to screenshot events through the window module. 22 23**Start API Level** 24 25API 9 26 27**Change Since** 28 29OpenHarmony SDK 5.1.0.46 30 31**Key API/Component Changes** 32 33No API or component change is involved. 34 35**Adaptation Guide** 36 37No adaptation is required. 38
