V172 : (i hope it's better or at least added log can maybe help)

Hi Seb
Tried v172, TV SD, HD and 3D look good but still problems in OV. The attached log and freeze report cover 2 attempts to play the vid you suggested from Das Erste, it played first time but hung MP on the second try.
Please note actually that is fairly unusua,l 640 content typically plays with very few hangs. It is the 1280x720 vids that seeem to show the problem most frequently, BUT, very strangly, not those, for example in ZDF mediatek, listed with an .MP4 extension, I can play those without seeing the problem(at least so far).. Wheras ZDF live which is also 1280x720 fails regularly.

Hope this helps.

Hi

Are we agree that with EVR mode all is ok ?

Yes, OV is 100% good with EVR.

Further to the above I have been trying various settings etc to try and clear the problem. The only effective thing was to set the "Hardware Decoder to Use in LAV from DXVA(copy back) to none or deselect the H264 codec OV then worked OK but without HW acceleration of course. I don't know if that helps but hopefully it might tell you something.

Very sorry but while playing I noticed a problem with TV using EVR. If I zap from a full HD channel to a regular one the picture zooms down from full screen as shown in the screenshot and remains that way on zapping to further regular channels but goes back to fullscreen for an HD channel. If the TV starts on a regular channel it plays in full screen, it is only when zapping from an HD channel. It is not a problem when using Madvr and is also not a problem with the original HEVC branch (I was able to go back to an old restore point).

Hi All,

v172 solved my blackscreen on stop issue
Just windows scaling is still not working well with MP... well at least not when playing files

 

[Sebastiii]

Hey
I'm trying to understand the issue from @joecrow on OV stop, it seems like MP is killing is own window (fullscreen or not) and i'm not sure why it does this.
I didn't seen this kind of log on my side.

About EVR and TV i didn't test it but i will, can you tell me the channel to channel to test ? (i have astra 19.2 sat) like this i should be able to reproduce
Thanks.

Nice

Could you make a video to explain it ? (just to be sure to fully understand thanks. )

 

[rohnfe]

Well as soon as Windows scaling is used set to whatever %, which really makes sense on a 4K screen, MP starts up as normal but as soon you start playing a video the following happens:

2D

• video somehow does not react to madvr scaling settings correctly for example one of the files madvr was showing was scaled to insane 8000x4000 pixels while scaling in madvr was set to 4K
• just came to my mind that windows scaling might have been set to 200% so maybe the scaling of madvr was just doubled ?

3D

• video is played in weird 2D looking kind of unsharp, almost like 3D but 3D is not working (madvr shows 3D, TV switches to 3D)

In the end this might be a madvr issue as well but for example using MPC-HC the exact same configuration is working fine, maybe because MPC is ignoring windows scaling idk

Hi
The problem shows itself with EVR selected as the renderer(NOT using the check box under the Madvr selection, not tried) If I start TV playing with channel ZDF-HD (1920x1280) then zap to BR Sud or Sat1 (both still 720 or less OTA for me) then the picture zooms down. If I start TV with Channel BR Sud selected it plays in fullscreen OK until I zap to an HD channel, also OK and then back again to BR Sud when it zooms down again.

Update:-

@Sebastiii After some thought, if you and others are also not able to reproduce the EVR problem I would suggest we put both issues on hold pending the installation of a replacement for my DOA AMD RX 460 in conjunction with a planned clean install of Win 10. Let me know what you think.

hey joe, i can reassure you.
tried it from zdf hd to sat.1 -same wrong scale problem with sd after hd tv only with evr enabled
v172 with madvr, tv seems ok. tvs and movpic too.



and tried ov a bit, seems that it works good here -even with many different sources and streams youtube,imdb,itunes,ard,zdf,arte live....all good


havent updated iptvsplitter, still on the old v2.2.15.6002
