Description

A recent Mythbuntu autobuilds 0.23-fixes MythTV is choosing 25hz for 720/60P sources such as ABC and FOX. It seems to makes its frame rate choice before it realizes it's a 60p source. This happens for LiveTV.

VDP: LoadBestPreferences?(1280x720, 25)

This is what is communicating to DisplayRes?... 1280x720 25Hz

I assign it to janne because I do not know what else to assign it to ; seems invalid to me.
The log are incomplete anyway to be able to pinpoint what's going on.

Could be that what's the user as defined the screen resolution as.

Anony Mouse,

Hopefully you care enough about this ticket to be checking on it-- if you respond again please do so with an e-mail so we can communicate with you as necessary. Does this *only* happen in Live TV? If you record the same program and watch it from "Watch Recordings," presumably it plays properly, with correct refresh rate? Also, please provide mythfrontend logs with "-v playback" .

Possibly dummy recording related.

comment:6 Changed 4 years ago by anonymous

It only happens from Watch TV not Watch Recordings. I haven't had time to investigate further but given the logs, I suspect fps gets set to 25 here.

Still need the requested logs, will close in two weeks without them.

comment:8 Changed 4 years ago by jyavenard

As why the 50Hz vs 60Hz with the dummy recording, I'm guessing that he has set his system as PAL in the configuration instead of NTSC or US etc..

comment:9 Changed 4 years ago by anonymous

The provided logs included "-v playback"
The system is set to NTSC.
It only happens on live TV not a recording.

comment:10 Changed 4 years ago by robertm

You included 3/10ths of a second worth of logs. Please attach *full* logs with -v playback. Gzip as necessary.

comment:11 Changed 4 years ago by anonymous

I added a log of watching Live TV on FOX.

Some other observations not in the log.

I start on FOX. It's in 50p. I change to ABC. It's still in 50p. I change to NBC. It switches to 60p. I change to ABC. It's still in 60p.

comment:15 Changed 2 years ago by Github

VideoSync?: Update the refresh interval after a video stream change.

An input change, as seen in live tv, may change the refresh rate which
then requires an update to the rate stored in the VideoSync? object. If
not, under certain circumstances the deinterlacer selection will fail
(and probably a range of other, more subtle issues).
