Media Player Classic Home Cinema (MPC-HC) - DXVA!

[St Devious]

Impossible to upload on MediaFire : it say at 1% a while .... and updload error ....
All the time...

did you make an account ?

you can upload without an account too but it asks you what folder do you want to upload the file to. this maybe why it is stuck at 1%, because it needs you to select a folder

@Casimir666: can you change the ReFrames limit in MPC-HC for nvidia+XP to 14 from the actual 11 ?
after revision 1141 even files with 15 Reframes and without bpyramid worked, but since your changes in the release candidates it dropped to 14.

There is a registry value that you can set that makes MPC-HC ignore reference frame count when using DXVA.

[adoy]

If you don't like waiting on sites like zshare, rapidshare, etc and you are using FireFox...

... Get the extension 'SkipScreen'! :) It works perfect!

perfect. thanks

yes, but then MPC-HC will try to decode even files with 15 and 16 Reframes, so you have to change the settings to watch those and then revert settings after.

Question: Where can I find the best settings for Internal and external filters on MPC-HC?

As I said earlier I was disabling all source filters and only leaving FLAC enabled, but all transform filters were enabled. External filters with only FFDShow video decoder configured to Prefer merit.

But I don't know if something else needs to be configured for best results. I installed K-Lite's codec pack here.

I am addressing my problem in the TSMuxer's thread, it seems the modified M2TS file was having problems with MPC-HC's default source filter called MPEG PS/TS/PVA. When this option is enabled, the modified file is running very fast (the original one, on the other hand, it's normal). If disabled, it's running with normal speed, but Haali's Media Splitter filter crashes MPC if I attempt to change any subtitle. Does that make any sense?

I assume the MPEG PS/TS/PVA source filter from MPC is perfectly normal, so no chance this might be a bug? Have you guys tried to use TSMuxer, generating a new M2TS file and removing some tracks/subtitles from any Blu-ray disc and played on MPC? It would be very important to check that. But not the first time you insert the disc on your drive. I mean, the second time (once the files are already there).

What makes no sense for me it's that BSPlayer can play either the original or modified M2TS files, no matter how I change them. The problem is that BSP can't display any subtitles from these files, while MPC can.

One more thing: only the MPEG PS/TS/PVA source filter from MPC is able to tell me, while the video is being played, the name of the subtitle languages (english, spanish, etc.). Haali will always say they are just another stream, not giving me any names.

So, yes, it sounds like an Nvidia only problem.

[DeathWolf]

Can anyone with an mkv with ass subs get mpc-hc to display the subs using an external vsfilter, and without using haali's media splitter?

I used to have an external matroska splitter that'd load up, but lately haali seems to load even if I block it, which is fairly disturbing if I may say.

(EDIT: note that the disturbing part is that blocking haali's splitter does not block it, it still loads)

EDIT2: it seems I just have stumbled on a strange matroska file. Will report more when I find out what's special about it.

[DeathWolf]

Okay, here's the conclusion and a bug report:
If a filter returns the subtitle track before the video one, it seems mpc-hc does not behave correctly.
(that was the particularity of that mkv file)

Another possibility is that the mastroska splitter should actually be returning streams in another order.

Anyone having problems with 1440x1080 anamorphic HD streams (BBCHD) ? When i try to play a stream like that my display/connection to my display "hangs". The image itself is played in 4:3 at first, DAR isnt applied. When i then stop the clip and randomly start another (regular, non-anamorphic) clip my display remains black, only audio is sent through. I have to reboot my system to get the HDMI connection fully up again (As in: Including video).

- MPC-HT for playing of the stream.
- Stream was BBCHD original, 1080i (MBAFF, 1440x1080 anamorphic, PAL 25 fps).
- CoreAVC as decoder.
- ffdshow audio-decoder for audio (Ac3 & DTS on through).

My system is on Win XP SP3. I have an Ati1950Pro as graphics board. 1 monitor out is regular VGA. The secondary out is used for media, it is connected by DVI->HDMI to an Asus HDAV1.3 Slim. The HDMI-out from the Slim-card is connected to an Onkyo SR875 with HDMI-out set on "Through". The Display used is a Panasonic F-HD plasma (shows up as secondary display on the 1950pro).

Never had problems with those streams before, and other streams play fine. It's only the 1440x1080/anamorphic streams that have problems.

[DeathWolf]

In reference to my previous bug report, here is a quick and dirty patch to put the sub streams at the end of the output pins rather than the beginning.

Quick suggestion. If in file->save image dialog we change file extension from dropdown menu, in resulting file we will get filename like somefile.avi_snapshot_2009.08.03.17_16_38.bmp.jpg. This is probably easy to fix.

If someone is editing naming, could they also change the date info to timestamp info which would be more useful for referencing for saving single image?

something like:
file.avi_snapshot_HH.MM.SS.bmp

Why you use video player, MPC-HC as picture viewer ???

[Snowknight26]

Why you use video player, MPC-HC as picture viewer ???

Nevermind what I said. I think I overlooked it being an non-MPC-HC issue.

With that said, seems to be a Generate Still Video issue. Turns out ffmpeg can decode it fine. Now if only MPC-HC could decode all the formats that ffmpeg could by default.

[DeathWolf]

wouldnt that be dshow support for tga that returns the good ol' flipped RGB32?

[clsid]

Instead of asking us to make pigs fly, you could just install some picture viewer. IrfanView is an excellent free one.

Sounds like a problem of driver to me.(more than mpc-hc) In particular a DXVA problem.
Do you have latest drivers?

[DeathWolf]

Oh and could someone with commit access check my patch a few posts ago and maybe commit it? It helps for many situations.

[G_M_C]

Dont use DXVA, as i wrote: I use CoreAVC as decoder (on Ati card, so no CUDA either; But QX9650 compensated for both easily :p ).

Is there any way to correctly display UTF-8 encoded .srt subtitles? I've tried different settings with no success, non english characters are wrongly displayed.

http://thumbnails.imagebam.com/4436/9f353b44354006.gif (http://www.imagebam.com/image/9f353b44354006)

It's supposed to display "¿Tú?", "¿" and "ú" are not standard English characters. Is this a known problem in MPC-HC?

[sneaker_ger]

You're not the first one with such problems (http://forum.doom9.org/showthread.php?p=1248604#post1248604).

I guess I could at least test if it works for me or if I get the same problem if you upload your subtitle file and tell me which container you are using.

[tiny]

MPC-HC doesn't not recognize the UTF-8 encoding if the subtitle file does not start with a BOM (http://en.wikipedia.org/wiki/UTF-8#Byte-order_mark).

The easiest way to add a BOM to a subtitle file is to open the file in notepad, (check if the non-standard characters are correctly displayed), then use "Save As..." and in the dialog select for encoding "UTF-8".

1) first problem: problem with HD subtitle and some blu-rays
http://sourceforge.net/tracker/?func=detail&aid=2805913&group_id=170561&atid=854651
With some blu-ray movies, some subtitles are not displayed with MPC-HC 1160
(this problem exists from the start of HD subtitle support).

When two subtitles must be displayed in the same time, only one subtitle is
displayed.

I give you an example of video (ten minutes cut in 7 parts)

The problem appeared between 8 minutes and 9 min30 during the generic.

There is two subtitles normally displayed: the subtitle of song and the
subtitle of text displayed on the screen. Only the subtitle of the text
displayed on the screen is displayed and not the subtitle of the song.

I try with powerdvd ultra 7.3 and it works very well. The both subtitles
are displayed.

part 7/7

I add file with all subtitles obtained with supread to show that some
subtitles are not displayed.
http://www.zshare.net/download/61317131a8f7ba09/


this problem still exists with mpc-HC 1179



2)second problem:
http://sourceforge.net/tracker/?func=detail&aid=2795839&group_id=170561&atid=854651
The problem with separated subtitle and opendvd function with evrcustom is
repaired but I have a problem with 1117 and the display of subtitle with
VMR9renderless

The problem is that with vmr9 it doesn't work as well as before. With
1.2.972 the subtitle are well displayed and are sync with sound. With 1117
some subtitles are displayed and disappeared before the right time.
Although the sync still exists. But the display of the subtitles is shorter
than with mpc homecinema 972 and it's more hard to read them

I give you a video captured by fraps to show the problem

vmr9renderless with mpc-hc 972
http://www.zshare.net/info.html?60353718-cd20d05bbed07514eed715858a499d96

vmr9renderless with mpc-hc 1117
http://www.zshare.net/info.html?60353398-b045b40ad86adf102458406f5ff12343

We can notice that with 972, subtitle are displayed correctly. With 1117,
subtitle disappeared faster.

at 5 seconds of 1117 and 6 seconds for the video with 972 there is two
subtitles displayed :
the first: [month of Sokarh, 7th day : 15:48]
the second: you've always spoken like that.

With 1172 when the first subtitle disappeared, the second also disappeared.
Then It appeared anew.

With 972 when the first subtitle disappeared, the second doesn't
disappeared and stay until the right end.

Moreover the transition between the subtitles are smoother with 972 than
1117


I give you 1 min of the movie

[neoufo51]

Is it just me or are iPhone 3GS videos not working well with MPC-HC?

Build 1179, Win7, Latest Nvidia drivers.

I'm seeing problems with every renderer, even with Quicktime installed.

1) System Default, VMR9, and Haali all play the video 90 degrees counterclockwise and with an incorrect 4:3 ratio.

2) EVR CP doesn't play AT ALL and says at the bottom that DXVA is running.

Here's a sample video from a friend's iPhone. Please confirm my findings.

http://www.mediafire.com/?djogghzjv1z
Would anybody like to address this issue with iPhone videos playing improperly with EVERY renderer?

I know it seems minor, but fixing this would obviously make MPC-HC more marketable to those who would like to avoid having to install the Quicktime player rather than Quicktime alternative? Tons of people are sharing these videos over email now and it would be nice to have MPC-HC be their one-stop shop for proper playback.

[tetsuox]

1) System Default, VMR9, and Haali all play the video 90 degrees counterclockwise and with an incorrect 4:3 ratio.

What AR is it supposed to be? From MediaInfo its showing 640x480, with DAR 4:3. With Rotation: 90degrees. Perhaps your friend recorded this upright? I.e. at 480x640. Maybe get him to tilt his iphone.

You don't need qt or qtalternative to playback this video either. Just ffdshow + mpc-hc works fine for me with your clip. Although audio doesn't playback with Haali's splitter, works fine with internal splitter.

No, it's filmed the right way. You can confirm by playing it in Quicktime player if you dare install that. It definitely has to do with the "tall screen" aspect of iPhone video that is mucking things up, but I don't understand why it would be rotated in MPC.

Also, it doesn't play at all with EVR:CP

[STaRGaZeR]

You're not the first one with such problems (http://forum.doom9.org/showthread.php?p=1248604#post1248604).

I guess I could at least test if it works for me or if I get the same problem if you upload your subtitle file and tell me which container you are using.

Thanks, it seems the problem is what tiny describes below:

MPC-HC doesn't not recognize the UTF-8 encoding if the subtitle file does not start with a BOM (http://en.wikipedia.org/wiki/UTF-8#Byte-order_mark).

The easiest way to add a BOM to a subtitle file is to open the file in notepad, (check if the non-standard characters are correctly displayed), then use "Save As..." and in the dialog select for encoding "UTF-8".

You're right. I've done some tests after knowing this and:

- Subtitles coming from an old version of SupRip, they look good in Notepad, but bad in MPC. If I open and save with Notepad, problem solved. After muxing the .srt file that looks bad into Matroska it still looks bad in MPC, and if you demux the subtitle track Notepad will see garbage now! It seems MKVToolnix needs BOM too as it does the same mistakes as MPC when muxing into the file.

- Subtitles coming from the lastest version of SupRip (v1.16) are correctly displayed everywhere, they don't need the Notepad trick. Oh well, I guess I'll have to redo my subtitles :rolleyes:

BOM is really needed everywhere?

[Mercury_22]

Since this version of Media Player Classic it's intend for a Home Cinema experience I think that the audio part it's been neglected.
Although decoding wise we've hit a wall, no more than 6 channels for E-AC3 and no DTS-HD (HR oR MA) due to ffmpeg limitation,@ Mercury
I fixed the True HD and LPCM mapping. The Eac3 is still 5.1 instead of 7.1 because ffmpeg return only 6 channels! Back and side surround channel are out on back.
Cannot fix the DTS, because it's decoded by libdts that didn't support 7.1. ...

IMO there are still things missing and easy to implement like those audio "options" existing in FFDshow but non-existing in MPC-HC.
I'm refering mainly to 7.1 and "same as input" speakers configuration, independent volume for every channel, custom matrix, ...
Am i the only one thinking this ?

Yes, and not only with audio. Video options need some attention: an option to select the interlace flag, an option for using NV12 (for hardware deinterlacing) or other colorspaces, etc. It doesn't have to be like ffdshow, but at least some basic functionality. ffmpeg-mt should be included too, it works perfectly fine now in ffdshow.

[sneaker_ger]

Thanks, it seems the problem is what tiny describes below:

Didn't know they had to have the BOM. Good to know...

You can correctly mux your files without BOM with mkvmerge if you specify their charset as UTF-8 though. Otherwise mkvmerge will assume they have your system's default charset.

I think all subs should be UTF-8 by default.
A warning is especially required because you cannot restore the subs once merged.

@ everyone

Please post your bug reports and feature requests on sourceforge if you haven't already (do check if its already been posted, update the existing report if this is the case)

Just to be extra clear, only 2 things are being worked on right now.
1. H264 DXVA (for the next stable)
2. EVR sync (ar-jar is adding his jitterfree code to EVR, will be backported to VMR9 too), this is a branch, will not be added to trunk soon.

If you want more stuff fixed/added, please join the team if you know how to code in C++, if you dont try to learn C++ and then join.

[sneaker_ger]

I could (as could everyone else in the mkvtoolnix thread (http://forum.doom9.org/showthread.php?t=120648)), but I'm not sure if it's really necessary. All subtitles within Matroska are UTF-8. Mkvmerge converts them when muxing. Incorrectly converted files (due to missing BOM and not having set the charset manually) result in errors which are pretty obvious (like the one STaRGaZeR got).

[STaRGaZeR]

Yep. However, if UTF-8 does not imply having BOM, how would I know if it needs it? It should have a warning, as in the tooltip mkvmerge GUI says that manually setting the charset is necessary with non-UTF files (among other things), which is not the case. It lacks the "and UTF without BOM" warning. Or better yet, auto detection of non-BOM files.

Yep. However, if UTF-8 does not imply having BOM, how would I know if it needs it? It should have a warning, as in the tooltip mkvmerge GUI says that manually setting the charset is necessary with non-UTF files (among other things), which is not the case. It lacks the "and UTF without BOM" warning. Or better yet, auto detection of non-BOM files.please take that dicussion to the mkvmerge thread, maybe you can convince the author.
