Unable to scan or tune on a FBC tuner within VU Plus Uno 4K SE

Peter Bašista

Hi,

I am trying to use Tvheadend 4.3-1857~g221c29b40 on a VU Plus Uno 4K SE receiver. I have compiled it using "this" Openembedded recipe.

I am facing an issue where Tvheadend is unable to scan any transponder despite the fact that

dvbv5-scan

utility can do it successfully. I am attaching logs from scan attempts via both

dvbv5-scan

and Tvheadend.

Scanning via Tvheadend fails due to a "no data" TIMEOUT.

The DVB adapter itself is supposed to contain a FBC tuner. It has two physical inputs and presents itself as a single DVB adapter with 8 frontends. Is it possible that such a configuration requires some special setup which Tvheadend normally does not do, but

dvbv5-scan

does?

I have tried to use

minisatip

in combination with Tvheadend on the same machine. I have configured Tvheadend to only use the tuners exposed by

minisatip@. The result was that scanning and EPG grabbing worked. But continuity errors appeared regularly even when watching unscrambled channels.

However, when I enabled the "RTP/AVP/TCP transport supported" option within the "Advanced settings" group of the @minisatip

adapter's parameters in Tvheadend, the continuity errors have disappeared and I was able to watch the channels normally. I do not know what this particular setting does and why it influences the occurrence of continuity errors. I have also "mentioned" it in a discussion about

minisatip

issue related to FBC tuners.

Afther I had the channels scanned, I have tried to switch back to using Tvheadend directly. The streaming somewhat worked, but with regularly occurring continuity errors. Scanning and EPG grabbing did not work. This behavior resembles an issue that was reportedly "fixed" within

minisatip

a while ago.
