Has anyone found a way to: Cyberlink MPEG-2 decoder when DXVA is enabled + Subtitles?

I'm really interested in that combination. Any fix/alternative to use DXVA+Subs wil help.

simply enabling the built in subtitle renderer will solve your problem afaik

[JaDz]

MPC-HC now tries to play all H.264 content with DXVA regardless of resolution/refs and causes noticable corruption in the video and occasionally on the desktop (http://i37.tinypic.com/2zex7w8.jpg).

Same here. Windows 7, ATI 4850.

[Polcius]

No, it doesn't work.

[clsid]

You need to disable DXVA in the Cyberlink decoder or use the internal MPEG-2 decoder.

[gngn]

No, it doesn't work.

works fine here. the usual settings for DXVA on XP: VMR9renderless as output renderer, the internal subtitles renderer on.

[Polcius]

Yes but if I do that I can't use DXVA in the internal MPEG2 decoder.

gngn, I don't fully understand this graph XD

gngn, I don't fully understand this graph XD

admittedly, "that" graph was pretty much pointless :p
i put up a new screenshot to show that DVD-subs + DXVA (in my case mpeg2-IDCT) works on XP. dunno about win7 thou

But do you use any special settings in MPC-HC? (I mean, "not default")

[GrofLuigi]

What is SPCDisableAnim=1 in ini file?

GL

[namaiki]

In options -> subtitles -> disable animation (is ticked).

If auto-load subtitles is checked in playback, the internal subtitle renderer is enabled and then soft subtitle animation like karaoke will stay still on the screen.

MPC-HC 1326

Изменения/Changes:

* CHANGED: Allow screensaver to activate when audio only (sleep is still stopped).;


Hi, I need someone to confirm that the above status not only allow screensaver to activate when audio only but happens when video too. Thanks.

[Tenki]

Two problems in this version (1326) right now.

1.If I use DXVA, VobSub won't run, so I can't see any subtitles.
(this problem is since 130x, the previous version are ok.)

DXVA off:

DXVA on:
http://img3.imageshack.us/img3/2817/dxva.jpg
You can see The DirectVobSub are disappear when DXVA run.


2. If I use MPC-HC to play DVD, MPC-HC can't change other subtitles when playing.
(this problem is since 130x, the previous version are ok.)

[namaiki]

Tenki, you need to enable 'auto-load subtitles' and use the internal subtitle renderer if you want to use DXVA.

In MPC-HC, View -> Options -> Playback -> and make sure there is a tick next to 'auto-load subtitles'.

[73ChargerFan]

I'd like copies of older mpc-hc releases, svn 1180 through 1235 or so.
If anyone has one or more, please pm me. Thanks.

When no DX9 compatible device (no video card) is installed in a machine running MPC-HC, several errors are throw:

EVR: CreateDevice failed, DX9AllocatorPresenter failed, D3DERR_NOTAVAILABLE
VMR9: CreateDevice failed, D3DERR_NOTAVAILABLE
VMR7: No video
Overlay: No video
Old renderer: Crash <-- shouldn't happen
System default (Video Renderer): No video

Should at least get video as it works fine in graphedit using Video Renderer.

Just curious, but what video card and OS?

[Tenki]

namaiki, thank you.
But it only solve the first problem.

If I use MPC-HC to play DVD (file-> open disk), MPC-HC still can't change other subtitles when playing.

[namaiki]

Tenki, in 'Navigate -> Subtitle Language', what options do you see there when playing that DVD?

Изменения/Changes:

Screensaver is still stopped when video is active. It will only activate when mpc-hc is playing only audio.

[boyumeow]

@Spec-Chum,
Sorry for not being clear, I mean in full screen mode but not D3D mode. I did get screen saver activated when playing .avi, but it did not happens on previous mpc-hc. I did not change any status, so I'm not sure what went wrong too. I will try out the previous version again before I report again. Thanks.

Edit: Yes, I have confirm mpc-hc1326 kick-in screen saver in my case while mpc-hc1323 did not during full-screen (not sure about window mode as I did not check). Can any1 double confirm its just me or any1 else is getting it. Thanks.

@Everyone about DXVA and subtitles.

DXVA and subtitles officially only works when you use the internal subtitle renderer in combination with an internal DXVA decoder.
We know that for some people different combinations of subtitle renderer and DXVA do work, these combinations are however not officially supported.

If anyone has any detailed information, on how to improve the internal subtitle renderer to further improve the DXVA/Subtitle compatibility please provide us with a patch or detailed technical description

When no DX9 compatible device (no video card) is installed in a machine running MPC-HC, several errors are throw:

EVR: CreateDevice failed, DX9AllocatorPresenter failed, D3DERR_NOTAVAILABLE

System default (Video Renderer): No video

Should at least get video as it works fine in graphedit using Video Renderer.Hello, its unfortunate that you got these results.
At this time we are only developing EVR-CP and VMR9-renderless, both depend on drawing a DirectX surface directly to the videocard, if the surface can not be created it will give you the errors you have reported.

It would be a good idea if someone could fix the cause of the crash in the old renderer (since its basically software based) and then applied a patch that would cause any failure of VMR9-R or EVR-CP to fall back to the old renderer.

[tetsuo55]

Compiling news:

I have done some research, and it looks like MinGW64 can completely replace MinGW32.

It works on 32 and 64 bit hosts and can compile both the 32 and 64 bit build of mpc-hc (and probably the same for ffdshow)
It is already used to build a lot of other programs this way.

Available here: http://www.cadforte.com/downloads.html

it offers a choice between msys and cygwin, not sure which one is best for us?

Also, for x64 hosts they offer x64native compiling which should speed up the compiling time considerably.

Yep, working without any problem (navigation too), but WinXP only (no go on Vista/Win7)

I don't think this is what you meant, but would it be possible to make a setting where the subtitles texture resolution is the same resolution as the video?

For example, if I select 'Subtitles -> 'Maximum texture resolution' as 'Desktop', it will renderer subtitles in full screen at 1280x800 even though the video is 1280x720, that would be fine, however, sometimes there is positional text (eg signs), which will only render correctly over the video if the subtitle canvas is rendered over 1280x720 pixels (ie exactly over the video), and so it ends up that the sign is positioned either too low or too high compared to if it were being rendered by for example, the DirectVobSub external filter.

[gngn]

... and so it ends up that the sign is positioned either too low or too high compared to if it were being rendered by for example, the DirectVobSub external filter.

check the option "Position subtitles relative to the video frame" under "Subtitles - Default Style".

Ok. But is there a way to force DXVA (other than selecting auto-load subtitles and EVRCP in the options).

It's weird because in PowerDVD9, DXVA+Subtitles works, but it has a bug where some subtitle lines don't show up. Very annoying. I'm just asking these questions about DXVA because it's the only way I've found to get a PERFECT deinterlacing (using Ati Avivo).

DXVA and subtitles offically only works when you use the internal subtitle renderer in combination with an internal DXVA decoder.
:confused::confused::confused::confused:
If a subtitling filter is connected between video decoder and renderer, DXVA cannot works. This limitation is caused by DXVA design, and cannot be changed. Only internal subtitle engine can works, because in this configuration subtitles are display by renderer (VRM9 renderless or EVR custom) and not by an intermediate filter.

[tetsuo55]

Ok. But is there a way to force DXVA (other than selecting auto-load subtitles and EVRCP in the options).

I'm just asking these questions about DXVA because it's the only way I've found to get a PERFECT deinterlacing (using Ati Avivo).Every application is only able to DXVA+Subtitles using their own decoder and renderer. (although some people do get lucky with other combinations, like the XP example above)MPC-HC displays video track information incorrectly:The internal splitter does not support multiple video streams at all, wierd behaviour is expected as it does try to do something with it.:confused::confused::confused::confused:

I'm just asking these questions about DXVA because it's the only way I've found to get a PERFECT deinterlacing (using Ati Avivo).Yes, we really need a built in MPEG2 decoder that supports HA deinterlacing (and preferably other DXVA acceleration too, although that is less important these days). This is stopping me moving to W7 right now as the Cyberlink decoder works with subtitles/DVD menus in XP, but not Vista/W7 (as I understand it).

When I play a BD structure folder subtitles can be selected (with Haali splitter) however, they are not displayed. What could be wrong?

I totally agree.

Maybe I should create an XP partition...

[Lincoln Burrows]

I hate when this sort of thing happens... and now it's not only limited to MPC, but other players as well.

Here's the situation: I tested the M2TS from one of CSI: LA (Blu-ray) episodes and MPC-HC is always using this filter to play those files which are using VC-1:

How to stop using WMVideo decoder DMO? (http://forum.doom9.org/showthread.php?t=111491)

And worst than that, even if I disable those Windows filters, the M2Ts files will not run. I tried several combinations, and also tried to force the external/internal filters from MPC-HC, ffdshow, Haali, etc.

Nothing seems to make those M2TS work (a black screen is what you get), except for adding the WMVideo decoder DMO as a new filter (that's right, we need to add) in the MPC-HC External Filter's section. :(

[tmbt]

Polcius :

In ati Avivo settings try to remove the flag on "useautomatic deinteralacing" and select manually a deinterlacing method. Works great for me and i don't need dxva anymore.

As far as I understand, you need to use the internal TS splitter and the internal sub renderer for them to work.

[THX-UltraII]

As far as I understand, you need to use the internal TS splitter and the internal sub renderer for them to work.

How do I use the internal TS Splitter and the internal sub renderer?

[Lincoln Burrows]

As far as I know, Haali can't display those subtitles, it's returning all sorts of errors, I don't know why. You need to activate VMR 7 or 9 renderless in the MPC-HC internal settings to display them.

Also, try to force MPC-HC to use ffdshow Video Decoder instead of Haali's, if that tip doesn't help.

P.S. Regarding my previous post, this is the first time I am seeing a M2TS file that is requiring me to disable VC1 (ffmpeg) and only use WMVideo decoder DMO. I tested other movies and they played fine, even the ones who used VC-1. Is there something wrong with some of them? This is really strange. And TMT is the only player that is not having any lag while playing this BD project, even when displaying subtitles. I heard somewhere that enabling VMR 7/9 renderless is requiring too much from the video card? Mine is NVidia 8800 GTS 512 MB, plus a Q9450/2GB RAM/XP SP3 system.

As far as I know, Haali can't display those subtitles, it's returning all sorts of errors, I don't know why.

I use noth ffdshow Video Decoder and Haali auto-loads. What do you mean exactly?

Regarding your VC-1 problem I'm almost sure it's a VC-1 i so none of the internal VC-1 filters it's able to decode it see http://sourceforge.net/apps/trac/mpc-hc/wiki/Troubleshooting_guidelines NOTE: Interlaced VC1 is not supported, because ffmpeg does not, ... For VC-1 interlaced material in EVR CP renderer Enable Frame Time Correction, but you have to disable this again for all other media ... Enable Frame Time Correction if you use WMVideo Decoder DMO

So by using VMR9 instead of EVR Custom MPC-HC can show the subtitles of a BD folder AND still use Haali Splitter?

Use internal MPEG PS/TS/PVA and hit RELOAD in Subtitles menu (right click-> subtitles-> reload) also use EVR CP

That one of many reason why my HTPC is XP based.

Can someone inform me(us) is there a problem with DXVA on Win7 with Catalyst 9.10 ?

For a week I'm testing Win7 32bit on amd780g platform (ATI HD3200) and can't have smooth DXVA with latest MPC HC and Catalyst.

Reproduction stutters no matter what sync/vcsyny/flush... option is enabled on EVR or VMR. It looks like there are not many dropped frames but stutter is clearly visible (like it plays in background and refreshes the screen from time to time). There are periods of smooth video then suddenly stutter starts like PC is busy with some backgorund task.

All of that is much, much better with 1043 version (without beliyaal addons) and no-dxva with CoreAVC is smooth without a problem.

Even earlier versions like 11xx works better then 13xx

As this can be Catalyst related (maybe some option to switch off ??) I would like to hear something from other ATI & Win7 DXVA users.

Did you try the MPC-HC-Gothsync branch?

[Jong]

That one of many reason why my HTPC is XP based.Yeah, but XP tears horribly for WPF and Flash-based apps with seemingly no way to fix it. I am sticking with XP for now as these are a minor interest at the moment - good Blu-ray, DVD etc. more important. But there will be a time when on-line video is critical and solving Silverlight/Flash etc.problems will be vital.

[Peekstra]

@krbo: Have you configured MPC-HC to use the option "Process priority above normal" (directly located under player in the options screen) ?

Also, I could only get smooth playback by enabling "Disable desktop composition" (on Vista).

[Lincoln Burrows]

Regarding your VC-1 problem I'm almost sure it's a VC-1 i so none of the internal VC-1 filters it's able to decode it see http://sourceforge.net/apps/trac/mpc-hc/wiki/Troubleshooting_guidelines ... Enable Frame Time Correction if you use WMVideo Decoder DMO

Use internal MPEG PS/TS/PVA and hit RELOAD in Subtitles menu (right click-> subtitles-> reload) also use EVR CPThat's right! CSI: Las Vegas is using 1080 interlaced. Since I don't wanna use "WMVideo Decoder DMO" is there something that I should do to display this M2TS file (other than using Total Media Theatre)?

I mean, whatever I do while using MPC-HC, it can't play (black screen) those M2TS files. Letting MPC use the WMVideo Decoder will make the image be displayed, but as I said before, the lag itself will not let you see things smooth so it will be useless. The lag is so awful that sometimes (specially when using renderless), the sound is out of sync. Even if I disable "VMR7/9 renderless" and choose to not display the subtitles, the image will have this issue. "WMVideo Decoder DMO" sucks, I wanted to use ffdshow Video Decoder from the start, but this M2TS interlaced material is not cooperating with me.

What should I do exactly to solve this issue? Or do you mean the ffmpeg (?) (VC-1?) decoder will support this 1080interlaced source only in the future, so I should only sit and wait until it's done?

EDIT: I found it: EVR Custom, like you said. Well, it's working, and still using the WMVideo Decoder. Subtitles also working. Sometimes the lag returns, but generally speaking is way better than before. What options should I select from here?

Well it depends on your graphic card I'm using Bilinear (PS 2.0) !
My recommendation for VC-1 i with WMVideo Decoder DMO:
1 reset MPC-HC settings to default ( + use EVR CP in XP)
2 disable both internal VC-1
3 a) for Windows 7 Enable Frame Time Correction + optional (= you have to decide / test if in your case it helps) Alternative VSync
b) for XP and Vista use "Reset to optimal renderer settings"

Same problem here, tried all this

How do you open BD ?
Follow this http://sourceforge.net/apps/trac/mpc-hc/wiki/Troubleshooting_guidelines and then report back with more info like your OS graphic card .....

And try this path to enable subtitles: Filters -> ...mpls-> subtitles. When you play "directly" the m2ts file do you have subtitles ?

Also you have to wait a few seconds before subtitles are displayed

How do you open BD ?
Tried both "Open DVD" and direct m2ts file open

Ok, later, when got more free time
