Live TV not displaying properly with Nvidia graphics cards.

[QUIKFLUX 6]

Hi,

 

When i start live tv through emby theater (ver1.0.44) all im getting is a forced 4:3 aspect ratio picture on my tv.

 

Ive tested this across 4 HTPCs. 2 pcs have onboard graphics (HDMI) they are intel HD Graphics 530 and the other 2 pcs have a nvidia gtx 960 and a gt 640. the 2 pcs with the onboard graphics display the live TV picture fine with full screen or 16:9 aspect. But on the 2 pcs with the nvidia graphics cards regardless of settings through emby theater im only getting a 4:3 aspect picture. 

 

Anyone seen issues like this or have a fix? previous versions of emby theater havent been an issue.

That's a very strange one. Which video renderer are you using? Does it reproduce with both EVR+ and madVR?

Hik, im using madvr...evr+ is even worse. i get half a tv screen as a picture using that.

[babgvant 143]

If you record this file type, does it work then?

[QUIKFLUX 6]

I cant record at the moment. I have a hd homerun tuner, but im in australia so i cant set up a recording of anything

[babgvant 143]

If you have a HDHR it's really easy to "record" a file using VLC. Just capture the network stream like this:

 

 

You'll want to pull the "source" from your HDHR's channel lineup.

Sorry, i cant get the stream to work through vlc.

http://192.168.100.23 is my tuner ip address in emby server, im running off the default port 8096, and the channel im trying to get to is v50

 

so would that make the source.....http//192.168.100.23:8096/auto/v50?

[babgvant 143]

http://hdhripaddress:5004/auto/vchannel#

 

so http//192.168.100.23:5004/auto/v50

 

easiest way it to get it from the HDHR channel lineup:

 

Should be here:

i have run 3 captures over 2 channels....all 3 when playing back are all fine in the full screen. But still the same issue when just starting live tv through emby theater on the same 2 channels i did the tests on

[babgvant 143]

I would suspect that it's something that ffmpeg is doing when it streams/transcodes the files through the server. We'll probably have to look at the server's logs to determine what command line args are being used. It should be possible to manipulate that to dump the file to disk instead of streaming it and have a look at that.

[QUIKFLUX 6]

Did you want a copy of my server logs?

[babgvant 143]

Just the bit where it uses ffmpeg would be good.

[QUIKFLUX 6]

Sorry where would i find that? If this is incorrect please let me know. One of the last things i tried that this log should pick up is me trying to play live tv...hope this helps

Hi there @@babgvant, was wondering if there was any update on this?

[jds828 24]

I tested this last night on a GTX970.

 

MadVR was a square 4:3 picture. Changed it over to EVR+, that worked fine.

[babgvant 143]

Hi there @@babgvant, was wondering if there was any update on this?

 

I did a search of the log, didn't find ffmpeg. I think @@Luke may need to point out where the cmdline would be documented.

Thanks for that. i have tried evr+ but when choosing this option my ratio is fixed but my actual live tv picture size is the only filling 3 quarters of my TV screen. attached are 2 photos that shows the picture i get with both options.

if it's transcoding the server will have a separate transcoding log for it

Hi @Luke and @@babgvant, are these the logs you are after?

Hi, i ran the command, but it seems to be failing.see below, the file it creates is zero bytes so i cannot attach it.

Let it run for a bit, then press Control+C to have ffmpeg close the stream. It is normal for it to look like a zero byte file until this happens.

The # after the v in "http://192.168.100.23:5004/auto/v8" indicates a channel. Find one that works, and exhibits the problem. Maybe channel 8 isn't a good channel right now.
