Hey  @kprojects,

We have seen reports on our subreddit and are following up with the development team. I actually just provided an update over there to the main threads (I really appreciate you calling out readding to ONVIF, as that was one of their specific questions).

Do you know if its particular to RTSP, and affects ONVIF as a result? Or is it a result of ONVIF itself? Do VLC Streams show the problem?

Hey Everybody,

So that nobody is left in the dark: our teams are taking a look at the reported behaviors introduced in the latest firmware update to the C120 and C121. While these appear to largely relate to the RTSP and ONVIF streams, we are seeing a few reports that the Tapo Apps behavior is also impacted.

I will provide an update from as soon as I can with more information, and we may end up reaching out to a few of you for additional information. I have given links to these threads, and I've summarized what we are seeing – but these are the questions that were also asked:

General

• What is the Connection Quality of Your Camera (Device Info > Tap on the Wireless Signal Icon)

• If your RTSP and ONVIF Performance is Affected, What Does Your Tapo App Performance Look Like?

• Have you observed any other significant changes, such as with the accuracy of pet detection?

Networked Stream Performance

• What RTSP/ONVIF Client Are You Using?

• Does your client report a reduced frame rate, dropped frames, or does it appear as a stable network stream with lagging video?

• Have you attempted to remove and re-add the device to your ONVIF or NVR?

• Are you able to verify if the behavior exists on both the Low and High Quality RTSP Streams?

Tapo App Performance

• If your Camera’s Performance in the Tapo is Affected, What is Your OS and App Version?

• Have You Tried to Toggle the Hardware Acceleration Feature in the Tapo App?

• Since the last update, is the time to load/view the stream from the Tapo App higher or lower?
