Multiple "stream" errors in HA with OnVif integration

Hi guys,
I have the following setup: HA - latest version 2021.8.6 - Hikvision camera(DS-2CD2021G1-IDW1) - Onvif integration.
In logs I can constantly see a numerous wave of errors regarding stream - like:

    Error demuxing stream while finding first packet:
    Error demuxing stream while finding first packet: [Errno 1] Operation not permitted: 'rtsp://homeassistant:PASSWORD@IP:554/Streaming/Channels/101?transportmode=unicast&profile=Profile_1'; last error log: [h264] error while decoding MB 75 67, bytestream -8
    Error demuxing stream while finding first packet: No dts in 7 consecutive packets

Any ideas on how I can address these? If I disable the Onvif integration - no more errors…but that’s not a solution.
The Onvif integration Configure shows:

The livestream from the camera works but it’s choppy and sometime freezes.
In the config file, I have both ffmpeg and stream components listed.
I do not know what else to try.
