Ive never been able to set my PC to stereo and have multichannel bitstreeming, I've always used AMD cards though, didnt know this was even possible. To get around windows dropping into stereo when it feels like it I have had to export the registry component for MMDEVICES and create a batch file that runs at logon just to ensure my PC remains in surround mode all of the time.
This is a windows issue though, not LAV related. |

Hello. Question about DXVA2/DX11 8K video - i have 1030 and it's support HEVC/VP9 up to 8k. But what's strange - DXVA2 decoder fail, your DX11 decoder fail, but Win10 "Movies & TV" playback with GPU accelerated(it's use DX11 engine for it). Any idea ??

I heard you need to use 64-bit for 8K to work.
In fact, just tried, works in 64-bit on my 1080Ti (doesn't work in 32-bit).

Hallo nevcariel,
I asked that on the Jriver support forum already but the forum seems pretty dead. Is there a way to load LAV audio decoder *and* AC3filter (AC3filter for mixing/post processing) in MC23? (Using the custom video filters setting) I have no problems doing this in any other app that supports DirectShow (w/ AC3filter only accepting PCM and have LAV do the decoding). But I can only load *one* audio decoder in MC23, not load both. (If I load LAV A.D. it doesn't load AC3filter, and vice versa) Thanks!! Last edited by Flexy; 12th April 2018 at 15:35. |

This is not the place for Media Center support, lets not start something that everyone might start abusing. Only questions directly about LAV are on-topic here.

There are no plans to work on that right now. Its a closed format for a closed ecosystem, which would take a lot of effort to get working and maintain, so motivation is not very high.

Hello, nevcairiel. After the release of the release version of "LAV Filters 0.71", starting with the first nightly build "0.71.0-5", became incorrectly reproduced "HTTP Live Streaming". During playback, there are periodic jumps in the frame rate, as well as a "torn" picture ("torn" frames) resembling tearing, which occurs almost instantaneously, with the loss or loss of some of the audio data periodically, i.e. the end of words simply simply drop out, and sometimes even whole words.

More information is likely required to make sense of your bug report.
What became incorrectly reproduced? All HTTP Live Streaming? How did you test it? Do you have an example we could test with to reproduce the issue? What player, hardware, OS, and driver versions are you using?

Try with the latest nightly version, https://files.1f0.de/lavf/nightly/LA...-0.71.0-32.exe, it may solve HTTP related issues.

I can give an example and a playback algorithm for you: 1. Opened the YouTube HLS link: https://www.youtube.com/watch?v=yvdXkHuV0DE 2. Opened the properties of the "EVR-CP Video Renderer" 3. I found the following problems, look at the screenshot: http://ibb.co/giwRSS It is these problems with HLS that arise in all subsequent night builds, after the release of version 0.71. |

Not sure about those numbers, but if I press Ctrl+J ("Display Stats") I sometimes see drops in the graph like this: https://i.imgur.com/mxp07Tq.png (MPC-BE x64 1.5.2 build 3544, if it matters, and LAV 0.71.0-32)

What does it mean to jump frames? This means that the frame rate is unstable and varies, for example, instead of 30 constant FPS, a jump to 31.5, or 32 and back to 28, which is already below 30. And this is naturally wrong. So it turns out some kind of warping, some interval (range) [~ 28 FPS -> ~ 32 FPS]. |

I can confirm that this happens since the version following 0.70.2.1-git. This, along with freezing. I made an issue about the other thing on GitHub and forgot about the weird frame stutter.

It would make it easier to just keep discussion of that HLS issue in the GitHub ticket:
https://github.com/Nevcairiel/LAVFilters/issues/199 As far as I can tell, the latest nightly (0.71.0-34) should greatly improve the situation.
