Hi @RTL8710, we haven't seen this issue before. Can you share more details about the audio / video codecs you are selecting? What is your viewer?

[RTL8710]

Hi,@niyatim23 ,only H264 video,usewebrtc-js test.

In actual testing, after obtaining the video stream, the video stutters every 10 seconds or so during playback.

@RTL8710 ,

The error is coming from the SRTP library the SDK depends on. Can we confirm if you are building with -DBUILD_DEPENDENCIES=OFF or ON?

Thank you for your response. Due to issues with my device's streaming, not due to KVS.
