    I recently bought myself a new amplifier (Denon AVR-X3500H) and decided to also upgrade to a 4K capable video card for my HTPC (ASUS GeForce GT 1030 2GB GDDR5). This card is connected to my amp via HDMI, and onward to my UHD TV. I have a separate TV server. I tuned in the Astra UHD Demo and SES UHD Demo channels and found I couldn't get smooth playback of these channels using RTSP (using LAV filters 0.73.1 with DXVA2 hardware acceleration enabled, so CPU usage is low). I then switched to the "UNC Paths" option and playback is perfect! Is this a known 'characteristic'?

    Just posting this for people who might be experiencing the same issue, but at the same time I would be happy to do further testing and submit logs for the devs if required.

    Hi :)
    Thanks for the report
    @Owlsroost can surely help, but it could be nice to post debug logs with RTSP and UNC for us to try to saw why :p

    I've had this for some time, UNC works fine but RTSP bad. I have never reported because I think the ethernet cable to my tv server is suspect (it goes outside, 5m cable). RTSP has no error correction, so perhaps check your network?

    Thanks for the suggestion, but I've got gigabit connectivity between the TV server and the client and use a managed network switch so I can monitor the respective network ports. No packet errors are reported so I'm pretty sure the connectivity itself is fine.

    post debug logs with RTSP and UNC for us
    Will do when I get home tonight.

    You seem to have attached two copies of the UNC logs (and no RTSP logs)?

    Also need the TV Server logs (for the RTSP situation).
