Same here it uses avcodec

Beta drivers...
They are meant mostly for developers to test Win 8.1 new features.

Thought so, didn't expect them to break existing functionality though.

First of all, great work Eric! :-)

I reported this to nevcairiel who directed it to you so I'll just quote it.

Quote:

I just updated to the newest version (0.58.1) and there seems to be a regression using QuickSync. From what I can tell it pretty much affects all types of MPEG-2 irregardless of container (.ts, .mpg, .vob). If you're lucky you'll get a few frames correctly but it'll then play roughly one frame per second making it a slideshow. Turning off QuickSync fixes the issues, H.264 works fine.

Windows 7 SP1 64-bit
LAV Filters 0.58.1 (32-bit)
MPC-HC 1.7.0.7634 (32-bit)
madVR 0.86.9 (32-bit)
Intel Graphics HD4000 (i7-3770) - v9.18.10.3165

I couldn't reproduce on an i7-2600 with Windows 8.
Plays great with the LAV + MadVR (ZoomPlayer and MPC-HC).
I'm using LAV as splitter (splitter source) in my tests. What do you use?
Also, try changing settings in MadVR and see if things change (like queue lengths, etc.). My MadVR settings is default + DXVA scaling.

diizzy · 19th July 2013, 16:39

I did a few more tests, something breaks when you enable hardware deinterlacing in LAV Filters (QS). I confirmed on both MPEG2 and H.264. QS and YADIF works fine though...
My settings are default in MadVR including scaling. Didn't notice it on H.264 earlier because I just a few files that are interlaced.
Best regards,
Daniel

nevcairiel · 19th July 2013, 17:36

Yeah i'm personally not really convinced that the QS hardware deinterlacing works all that great, or it fails when i disable timestamp correction in QS, or something, but i've heard numerous problem reports from it.

Generally, you should just turn it off, and turn YADIF off as well, and just let your renderer do the deinterlacing.

egur · 20th July 2013, 14:56

I also checked with and without HW deinterlacing. Still works on all my 18 MPEG2 test clips.
In one clip, when HW DI is off, MadVR had issues. This clip is a pathological case where the stream switches between soft and hard telecine (evil_trees.ts clip).
Normal clips had no issues.
The reason I asked about the splitter is that some splitters may produce very bad time stamps affecting playback, nothing I can do about this...

Please share a representative clip (<100mb).

diizzy · 20th July 2013, 18:20

I can cut a few regular TS files too but here a MTS file.

I use LAV Filter as splitter, missed to mention it earlier.

What a dick move to Windows 8.1 to find Lucid doesn't work! ffdshow works fine though with QSV, if not better on Windows 8.1

Hi.
I'm using Marumo ISDB Splitter, which supports PID change in a service of ISDB stream.
http://www.marumo.ne.jp/junk/isdbsplitter-0.2.19.lzh

I can't use Intel Quick Sync Decoder with this splitter.
egur's ffdshow won't start playback of any ISDB stream.
LAV Video Decoder can't select as an active decoder for any ISDB stream.

Is this an issue of Intel Quick Sync Decoder?
Or of Marumo ISDB Splitter?

Here is my playback environment.
OS: Windows 7 Professional SP1 64bit
CPU: Core i5-3570 Intel HD Graphics 2500 (9.18.10.3165)
Player: MPC-HC rev7646 (x86)
Video Renderer: madVR 0.86.9

egur · 23rd July 2013, 21:12

I don't know whose fault it is...
Could be a different (unsupported) fourCC code or an unsupported profile.
If there for me a way to test this?

VFR maniac · 23rd July 2013, 21:46

What is needed for you to test and confirm this issue?

At least, I can use Quick Sync Decoder of your ffdshow and LAV Video when LAV Splitter is used to split from ISDB stream.

egur · 23rd July 2013, 22:09

For testing I need a sample file and how to setup this splitter. If this splitter require connection to a live TV broadcasts (not via the Internet) then I can't test this.
What is this splitter used for?

For local file playback.

OK, here is a sample: http://vfrmaniac.fushizen.eu/TX_noise_sample.ts
And the setup is just doing "regsvr32 isdbsplitter.ax".

egur · 24th July 2013, 15:25

@VFR maniac
I reproduced the failure with this splitter but I don't know what the exact cause is. It's sending a different stream than LAV splitter.
This splitter doesn't work at all with some of my TS files (H264 and MPEG2) - simply doesn't connect to the File Reader (Async) filter needed for playback.

My suggestions is to use LAV splitter.
Unless you're the developer of this splitter, why would you use it?

LAV Splitter (libavformat) doesn't support PID change in a service.
A certain TV channel I frequently recode changes PID when a SD TV program is changed into another HD, and vice versa.
So LAV Splitter is useless unless splitting TS file at points of PID change.

In addition, this splitter supports decryption of Japanese ISDB stream through smart card reader with B-CAS card.
For people who legally watch encrypted ISDB stream in Japan, LAV Splitter is absolutely useless.
