Video image corruption on Dahua Starlight vari-focal cam.

[dodamn]

The attached screenshot is captured from VLC player.
I see live view(rtsp stream) from VLC player. As you see, video is corrupted.
Also, recorded video by FFMpeg is corrupted samely.
But video is clear from Dahua web viewer.
I don't know why this happens. How can I fix it?

Video encode mode: H.265
Smart codec: On

For Ffmpeg, it seems that "-rtsp_transport tcp" option is solution.
distortion in video (ffmpeg, vlc and iSPY)

But I cannot find a solution for VLC.

Disable smart codec.... it's proprietary...

Thank you.

When I turn off smart codec, VLC still shows distorted frame for the first short seconds. In comparison to totally distorted video with smart codec, this is better. So I do not use smart codec.
But.. even though smart codec is on, ffmpeg with "-rtsp_transport tcp" works well for me. I don't know why.

This is likely because its waiting for an iframe...lower your iframe interval to match your fps and see if it helps.
