LAV Filters - DirectShow Media Splitter and Decoders

nev:
I tried enabling LAV mixer and it didn't have an effect (I guess it only mixes channels).
Is it possible to add a setting to cap (downsample) the sample rates higher than a certain user specified value?

the only thing which helped was renaming the MPC-HC64.exe file

I did some searching and the following works for a lot of people with similar problems:
Delete this folder: %programdata%\NVIDIA Corporation\Drs
(this is where the profiles are stored)

Uninstall Geforce Experience, or at least disable its services.

Edit: fixed location

there is no "Drs" folder in my username\appdata\local\nvidia corporation folder

(I deleted the mpc-hc profile yesterday though in profileinspector)

%APPDATA% (C:\Users\user\AppData\Roaming) is not %LOCALAPPDATA (C:\Users\user\AppData\Local).

[Thunderbolt8]

appdata\local is the only directory containing a folder "nvidia corporation" for me

[clsid]

It's in %programdata% (C:\ProgramData)

An interesting issue, trying to use LAV source to load this MP3 stream and it fails (right after specifying the URL):
http://downloads.royalsociety.org/ev...ne-therapy.mp3

No issue downloading and then playing the same file, any ideas?

I verified it fails in GraphStudio as well.

Maybe the leading ID3 tag with XMP metadata confuses a streaming client to estimate the bitrate?

I tried to run MPC-HC 1.7.11 (using internal LAV splitter) on Win10 to open an Avisynth script delivering YV12. It failed to render the script. When I downgraded to MPC-HC 1.7.10 everything worked. I would like to know if this is a possible LAV splitter bug and if so, if there is a work-around. Thank you.

[LigH]

I guess LAV Splitter may prefer to analyze input files (only by binary file content, without considering VfW hooks) to discover their container format, and may not recognize AviSynth scripts as media containers. If this depends on the MPC-HC version, it seems there is a handling exception for this case missing.

[videoh]

Thank you for your reply. I should have mentioned that if I add ConvertToRGB24() at the end of the script then MPC-HC 1.7.11 opens it fine. So it seems that it is not an issue of Avisynth support but rather it is specifically limited to YV12 support.

Other solutions:
- install external LAV Filters
- fix your i420 codec:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
vidc.i420 = iyuv_32.dll
(certain Webcam software fuck up this registry value and don't restore it during uninstall)

[LigH]

Still funny that it works with MPC-HC 1.7.10, so there must be a difference in handling raw YUV formats?!

Still fails.

It's already correct.

Maybe Nev can shed some light.

If using "LAV Splitter Source" stream playback reload from start after returning from pause state. Steps to reproduce:
1. Add "LAV Source" to GraphStudio, use "http://podcast.dimitrysmirnov.ru/blog/wp-content/uploads/2017/02/propoved-82258/propoved-82258_i.mp4" as the URL.
2. Add "LAV Video Decoder", "LAV Audio Decoder", "EVR" and "Default DirectSound Renderer"
3. Connect filters.
4. Press play and let the video continue for 30seconds.
5. Pause the video.
6. Wait 1-2 minutes (network timeout on connection?)
7. Press play.
8. Content plays for 20-50 seconds (remaining buffer?) and then stops automatically before the video ends.

Any feedback would be appreciated.

AC3_5.1 selected by default rather than DTSHDMA_5.1. This value didn't work for .MKV files:
[HKEY_CURRENT_USER\Software\LAV\Splitter]
"PreferHighQualityAudio"=dword:00000001

Any feedback would be appreciated.

[max79]

On my NVidia video card[Asus-GTX1060_6Gbyte] LAVVideoDecoder can play "AVC High@L4" without green image distortion only in "DVXA2 (native)" mode. Why "NVIDIA CUVID" mode didn't work well(and "DXVA2 (copy-back)" too) on all possible for downloading drivers for Windows_10_64bit from official NVidia site?

Any feedback would be appreciated.

Is the AC3 track marked default or forced? Different languages? Is your player overriding LAV choice?

I don't understand what do you mean "forced"? My settings:
[HKEY_CURRENT_USER\Software\LAV\Splitter]
"substreams"=dword:00000000
"prefAudioLangs"="rus,eng"

If the answer on one of the your two remaining questions was- "Yes", then the same problem would be and with other types of containers. But i have problem ONLY with MKV!

Info from "Media Info" about .MKV-file with two RUS-audio tracks:
Audio Menu ID: 1(have AC3 format)
Audio Menu ID: 2(have DTS HD MA format)
