Hi Nev, I was wondering if it would help 'weaker' hardware to add to 'queue settings' maybe also 'minimum values' ?? Kind of a first buffer before the renderer kicks in ??

buffers like this can be shared between decoder and the renderer and a high buffer may even break decoding (nev already limited buffer sizes for known cases like this.).

if you want a bigger buffer for weak hardware both EVR CP and madVR support custom buffer sizes.

Hello.
I'm facing the following problem.
I'm using umedia server and its player (http://www.umediaserver.net/umediaserver/download.html)
When i use lav filters with no hard acceleration (just avcodec) and i move the player's window from one monitor to another
the image becomes black.
Moreover after watching for a few minutes(without moving between monitors) then suddenly it also freezes.
The former doesn't always happen.It may happen after 2-3 minutes or 10-20 or never.

When using hardware acceleration(cuvid) then the image is working fine(i can move the window between monitors) but audio is lost...
Using ffdshow or even using the windows' implementation(no external filters) i have no problems.

I was looking to find a solution for a few months now and i couln't believe that it was due to this.
Any ideas please?

BTW thanks for your work nevcairiel.

Thanks!

Btw Aleksoid1978 (big THANKS) did special version of MPC Video Decoder with skip non Intra (and standard standalone version with skip B-) frames option is in ffmpeg so SAT-amateurs don't need to use MainConcept HEVC Video Decoder for non-accelerated h265 4K and 8K streams to watch slideshow http://smartdvb.net/bb/posting.php?m...it&f=13&p=6596

@Nev. I have the following problem.
MPC-BE (4176) + LAV (73.1) with Splitter and Splitter Source prefered trying to play AVI => BE hangs !
- Set 'Splitter source' to blocked => AVI plays but no sound !!
- BE all internal plays the files just fine.

And do I really have to install both Splitter and 'Splitter Source" ? What's the difference between these two ?

LAV Splitter vs LAV Splitter Source

Hm, do we need to add File Source (Async) for MPC-BE, too?

bug

I have to report a bug in LAV Video

if we enable avs script in video player, like Potplayer, with LAV Video, avs script won't work, player saying you are using DXVA, how could that possible, I've always set DXVA to none in LAV Video
I've tested the filters one by one, found out that the problem is LAV Video, switch to other video decoders it works again

please fix, thanks

Hi, and firstly, thank you very much for the job done with Lav Filters, that I appreciate using with mpc-hc.
I just tried the new dav1d decoder with latest SIMD optimisations included, through a recent mpv build, and the performance is astonishing. 4K samples that could not be played in a good way even with an hexacore are now handled very smoothly with little CPU occupation. I wonder if it would be possible to integrate this code in a future version of lav filters (as ffmpeg does) in order to benefit from this work. It seems to be in a compatible open source license, so I suppose that it would be allowed, but I guess it would need some work, so maybe if you happen to get some spare time some day...

Support request - #32

Is it possible to somehow supply the user agent in LAV Splitter Source ? I'm noticed that i can connect to this radio stream only if run it like this:
ffmpeg -user_agent Mozilla -i http://95.188.107.89:8008/LR_Russian.mp3

Any feedback would be appreciated.

LAV author has already said he will likely include dav1d in the future (unless some other free decoder ends up being faster which is unlikely). I bet dav1d will be in LAV filters long before you (or me) use AV1 for anything other than samples. There is no need to rush.

I'm noticing something strange, if I connect my Android tablet to the PC using MTP and view the directory of files, LAV will place multiple copies of its icon in the systray.

I am not opening or playing files, yet something is being triggered.

When I hover the mouse over the LAV icons, they will all disappear one by one.

Something in the background is using LAV to look at the media files apparently. And its not closing down the filter graph properly so that LAV doesn't get a chance to fully remove its systray icon again.

Use for example ProcessExplorer to see which process (.exe) is loading LAV. Then it could be added to the trayicon blacklist.

MTP is really annoying. It checks if the files are compatible with formats supported by your device.

@ nev. Would it maybe an idea to add (basic) profile ability ??
I am asking because on my system I can use DXVA2-copyback on everything up to 1080p but unfortunately I do need D3D11-native for UHD !!

There are no plans for profiles.

Perhaps the ability to specify a hardware decoder for each of the three resolution types SD, HD, 4K?
Some might even find it useful to select a different hardware device for each resolution type also.
A lot less involved than profiles.

Atmos drop outs

Nev, I have noticed issues with Atmos drop outs on the Incredibles 2 disk and others are reporting the same on different threads such as

https://club.myce.com/t/atmos-audio-...0/106?u=careca
https://yabb.jriver.com/interact/ind...html#msg818879

One of the users posted a log file in the JRiver thread. Is this something you are aware of? Do you need a sample MKV?

Thanks

I can probably look at that soon, but if its even happening in decoding, its likely the disc is fubared.
