That's after ~10-15minutes after the IPTV channel does start playing - which is one time out of 3-5. In most cases is stops after several seconds. Other channels seem pretty same when looking at OSD but still somehow different because they do start playing without issues. |

Not that i had an issue sticking with 390.77 as it was working fine for the games i play, but didn't want to stick with it forever and these days video playback and MadVR takes higher priority that gaming for me. |

Strongly suggest you leave that option as "application". Quote:

Tried tinkering with options and to max out CPU queue (128 frames) but nothing helps, playback just stops for some reason. |

It's been a long time since I played with IPTV streams, but last time I remember the internal stream source of MPC-HC was kind of flakey with UDP streams. Not sure if that's improved over the years.
You could try using VLC as a buffer, demuxing the stream and repacking it in to another format and sending it over another protocol might help. You could also try making the madVR buffers very small if you haven't already. |

@mv Is there a way to increase the minimum buffer at the start of playback for network streams in your player?
With MediaPortal I had the same issues sometimes on Live TV, playback would sometimes stop like if it had reach end of stream because the player was starved of data. I fixed it by setting a 2 second buffer. It didn't happen only with madVR, but somehow it did occur much more often with it than with EVR.

I have also noticed better performance with small buffers in madVR, I keep the "number of frames presented in advance" at 3 or 4 and GPU buffers at 4 or 6. I noticed this when I switched to Windows 10 but it doesn't seem to be a universal observation (there don't seem to be any universal observations).
It is a good idea to put "strength during fade in/out" on the same level as "default debanding strength" for reduce banding artifacts (if it is enabled) or keep the trade quality for performance option "don't rerender frames when fade in/out is detected" enabled (recommended anyway, in my opinion).

Thanks for advices guys!
Increased buffer size in LAV splitter (up to 512Mb) and tried increasing/decreasing buffer/queue size in madVR and somehow it did increase overall stability but unfortunately didn't fix the issue completely. |

Can't see any changes after upscale
Hi to everyone!
I'm trying to use some upscale settings for improving image quality using MPC HC and madvr. My target is upscale from 720p and 1080p to 2160p. I used 720p anime and 1080 bluray movie at medium settings and high profile to upscale 2160p but I can't see any changes for image compared to the original.I have a lot of drops frames seems to upscale algoritms working but when i pause and save image as png/bitmap 100% quality (alt+i) at from MPC I don't see any changes. The screenshots result are identical wich is weird : source 1920 x 804 (4.2mb) and after uscpale 1920 x 804 (4.2mb); -1280 x 720 1.88mb (original) and 1280 x 720 1.95mb upscaled. Another result for 720 source: (print screen) -3840 x 2160 (720p source) 23.7mb bmp - 3840 x 2160 (720p source) 23.7mb bmp (after upscale) My setup: Win 10 X64 with last update, latest MPC and madvr; Intel Skylake i5 6500, 8gb ram, GTX 1050ti 4gb, ssd Samsung 256gb, Samsung TV 55ju7500 2160p resolution 60hz. |

in the mail they sent me they are asking about app freezing (i never talk about freezing) and performance issue (never wrote about performance) they ask me to demostrate with a video the issue. Also seems it's not clear that the issue is happening from many versions of the driver. I'm not sure that i want to do their job, debugging, starting from update my system to a driver that I already know is broken to send them what ? something that they can reproduce easly (they are amd) with the information that i've sent to them in terms of repro steps and software e Hw versions. AMD is keeping to piss me off (sorry to be rude), starting from couple of years ago when they removed all video configurations in the drivers , they made me waste a lot of time to provide them all infomations requested and in the end all those useful controls never went back they closed the issue with no issue. this is my opinion, if you have time to break you pc with broken driver and send them all the infos i say a big thank you to you , but i'm not sure that i will do the same. |

I wanna ask why I send original dolby vision HDR mediadata with madVR to my TV set,my tv set doesn't decode the original dolby vision HDR? I'm very confient that there are hardware decoder chipsets on my TV set because i play some demonstration films from dolby co. website with my tv set.Doesn't madVR support to send original dolby vision HDR content to the display?Just support to send HDR10 content to the display?

Dolby Vision decoding is not supported by anything free, as far as I can tell.
Playing back Dolby Vision is not simply sending different metadata, it is much more complex and no one has released the specs so no one knows how to do it.
