Test fail for MEDIA2_RTSS-1-3-1-v25.12 MEDIA2 - H.264 (WebRTC, Default Profile) in ONVIF Test Tool 25.12

[hsiaoys-sketch]

When I run the test item MEDIA2_RTSS-1-3-1-v25.12 MEDIA2 - H.264 (WebRTC, Default Profile), the test fails if the profile bitrate is higher than 5000 kbps.
The RTP payload size of the DUT is 1200 bytes.

The failed steps are:

STEP 61 - [Profile default]: Wait for the DUT sends 10 correctly ecoded frames over WebRTC for each media stream StepStart: 2026-02-24T07:39:08.2373107Z
The DUT didn't send correctly ecoded frames within operation delay timeout for the following media streams: video/H264 STEP FAILED

How to fix the issue? Is this a computer performance issue?

Hi!

Thank you for the feedback!

Could you please tell what Operation delay value you use. You can check it on the Management tab (see the screenshot below)

Default or low value can be the reason of the issue. Please try to increase it. For example, I use 10000 or 30000

Thank you for your reply. My original "Operation delay value" was 30000. After changing it to 60000, the test passed.
