ffdshow tryouts project: Discussion & Development

[tal.aloni]

BUG REPORT!

After ffdshow tryouts project, svn 3247, when using "ffmpeg-mt" decoder, ffdshow refuses to auto load custom profiles (presets). It always loads default profile only.

I have tested 3257, and I have no such issue.
make sure you use the latest version and that ffdshow is loaded for H.264

[Sebastiii]

After a week of intensive code review, I've finally nailed the galbled-seeking issue:
it turns out that there is mechanism in ffdshow that drops input samples when decoding of current sample failed.
(in DXVA, we "fail" some input samples on skip)

I've disabled this mechanism for DXVA. (rev. 3258)

Thanks Casimir666 for providing guidance, and xhmikosr for additional assistance.

p.s.
1. for some reason, this affected only (or mostly) Windows Vista / 7.
2. during my long debug sessions I've uncovered some additional places that could use some improvements.

Big thanks :)
Seb.

Amazing work!!! Thank you and all the other developers for all the time you have put into this, it is greatly appreciated.

Can't find 3258?

[XhmikosR]

You can try the link in my signature.

[rica]

Thanks, i'll give it a go. :thanks:

[rica]

Quick test results:
No seeking issues with DTSHD-MA left but seeking issues for THD still persist. (at least better comparing with the previous btw)

[thuan]

Have any of you tried 3258 by XhmikosR, I can't make DXVA work here. It's just stuck right at starting playing. I tested MKV with H264 video using internal MPC-HC splitter.

Yeah its not starting me neither

[onomatopellan]

Using Haali Media Splitter -> no problem here!

[rsd78]

Still getting blockiness (but no repeating frames) after skipping/ff/rew in 3258 using Win 7 x32. I think it might be better but can't say for sure.

[rpm7200]

please add to dxva filter bt.709 . blu-ray movies use this. and thanks for hard working.

Good day to all

I call on the compatibility of new releases of ffdshow with MediaPlayerClassic Home Cinema.

I noticed that with the latest version ffdshow_rev3200_20100112_clsid_icl10 or ffdshow_rev3256_20100208_sse_icl11, pin Subpicture the DVD Navigator is connected directly to pin In Text of ffdshow.
In this situation do not play forced subtitles.

Using version ffdshow_rev2099_20080903_clsid_sse_icl10 pin Subpicture the DVD Navigator is connected to pin Subpicture MPEG-2 Video Decoder.
In this situation will play normally forced subtitles

can solve this problem with the latest release of ffdshow or do I use the old release?

THANKS

[hoborg]

@DMD
Can i ask why do you have two video decoders in one graph?

[DMD]

use ffdshow as a post processing, also in the setting of MPCHC I can not only set ffdshow video

[hoborg]

You should have only one video decoder in graph:
http://hobring.esero.net/saf/FFDShow+subtitles.jpg

Disable MPC-HC internal MPEG-2 decoder, add FFDShow as external filter and setup it as prefered.

[rsd78]

blockiness or garbled output?

Good question, I don't remember exactly but I would describe it more as garbled output I think.

[Midzuki]

@DMD

Even though I use DScaler5 for DVD-Video, I'd like to use ffdshow's "raw video filter" at the same time. However ffdshow will connect to the subtitle pin of qdvd.dll if I use it. I would not complain about ffdshow NOT having *independent* video-processing/subtitle filters, IF these could resize correctly the SUP streams in *non-D1* VOBs. :(

Hi thanks for reply.

I just tried ffdshow_rev3259_20100211_sse_icl11 and the problem is still there. Please not that you have to select "ffmpeg-mt" in ffdshow as the h264 decoder and play a h264 video file (mkv), in order to reproduce the problem I mentioned.

Thanks again.

[tal.aloni]

PetitDragon,
I did select ffmpeg-mt,
In which revision the problem starts?

you can find older revisions here:

Which GPU?
Which Renderer?
Have you tested multiple files?
Do you have the same issues when using MPC-HC DXVA decoder?

Guys, anybody else still have problems with skipping that are not present in MPC-HC DXVA Decoder?

Hi tal.aloni,

After install, reinstal many times, rev3247 is the last revision that works ffmpeg-mt and custom profiles loading together for me.

My player is Media Player Classic Home Cinema x86 (latest revition).

Thanks for your help.

[VipZ]

@ Tal, thanks for the awesome work :)

Seeking seems perfect now, I had one MPC-HC crash on immediate seek while opening file, but I cant reproduce, so don't think it's an issue.

Sorry for not providing more info earlier:

Win 7 x32, ATI 2600xt. Playback under Windows Media Center (so I believe that is EVR), and using Haali.. I tested 2-3 different 1080p mkvs and all exhibited the same issue. This happens regardless of whether the subtitles are actually displayed currently or not, but doesn't happen if I enable DXVA but don't enable subtitles (i.e. Overlay).

I don't have mpc-hc on that machine, but can test later tonight.

[Keiyakusha]

Is it possible to configure h264 lossless encoding settings to get exactly the same result as gives x264 cli with "--crf 0 --preset ultrafast"?

[RNiK]

So as mentioned above, FFDshow project was stoped in 2006 and continued by FFDshow-Tryouts since the... But when I tried to download the last version from http://ffdshow-tryout.sourceforge.net/download.php this is what I found: 2008-12-21 Beta 6 has been released! yet FFDShow MPEG-4 Video Decoder seems newer: 2010-01-09Beta6 is the latest official stable release. But development still continues and builds are available here:
http://sourceforge.net/projects/ffdshow-tryout/is a new beta going to be released soon since it's been over a year from last beta?+1 for her34 request.

Really guys, ffdshow tryouts official homepage linking a 14 months old version is just bad communication. :(
Beta 6 requirements ignore at all both Windows 7 than all Microsoft 64-bit O.S.
In the FAQ (http://ffdshow-tryout.sourceforge.net/wiki/faq:releases) you can read:
What is the difference between official releases and SVN builds?
SVN builds are “bleeding edge” which means they contain the latest features, updates, and - unfortunately - bugs. They are usually released a few times per week. Official releases are - simply put - “based” on these SVN builds. When an acceptable feature and stability level is reached during development, one SVN version is “destined” to become the next official release.So you are telling us that in the last 14 months were not developed features/updates stable enough to become "official"?? :confused:

[tal.aloni]

Thanks for the effort,
are you saying that 3247 load custom profiles, and 3248 does not?

because nothing even remotely related has been committed in 3248.

Tal

[tal.aloni]

but doesn't happen if I enable DXVA but don't enable subtitles (i.e. Overlay).

oh, I see. (no need to check MPC-HC DXVA decoder then)
DXVA Surface overlay does have additional demands that can cause garbled output, especially for older CPUs. (which CPU do you use?)

do you have those problems only on skip, or also on regular playback?

p.s.
this may be solved for you when DXVA 2.0 substreams will be implemented, as some of the load will be handled then by the GPU.

Thanks Tal.

Actually my cpu is relatively beefy (e8400 at stock speeds). I have plenty of ram (4gb). The system doesn't have any issue using software decoding.

The problems only manifest after a skip or ff/rew, regular playback is completely fine.

[STaRGaZeR]

With r3259 I get almost perfect playback using DXVA, no problems whatsoever on seeking. The little problem: when the end of a VC-1 movie is reached the player crashes with an error in ffdshow.ax . Also there are some things that I miss in the DXVA decoder:

- The usual "Show / hide filters" tab.
- "Info & CPU" to actually show something.
- The "Set interlace flag in output media type" option. Is this even possible with DXVA, or it's always present? Even if that's true, can it be forced to bob or weave?
- Is faster seeking possible? With some Blu-ray movies like Pirates of the Caribbean it can take up to 5 seconds to seek to certain places. Seeking in this movie is also slow with software decoding, but with DXVA is generally much worse.

Great work tal!

[VipZ]

@ Tal

I have found some issues with seeking with rev 3259, but not sure if ffdshow is at fault.

Haali MKV + MPCHC DXVA + Subs ticked : No issue
Haali MKV + ffdshow DXVA + Subs ticked : No issue
Haali MKV + ffdshow DXVA + Subs unticked : Possible crash
Haali MKV + MPCHC DXVA + Subs unticked : No issue
MPCHC MKV + MPCHC DXVA +Subs ticked: No issue
MPCHC MKV + ffdshow DXVA +Subs ticked: No issue
MPCHC MKV + ffdshow DXVA +Subs unticked: No issue
MPCHC MKV + MPCHC DXVA +Subs unticked: No issue

Subs where done via MPCHC not ffdshow DXVA

If you need me to try get any more info on this let me know.

Thanks

Hi ta,

I always followed the releases in the page www.xvidvideo.ru/ffdshow-tryouts-project-x86-x64/ before, and rev3247 is the last working revision. I just tried the releases in www.mediafire.com/?sharekey=3...e79d7d0540e1e1 you provided, and the last working revision for me is rev3248.

Sorry for confusion

[DMD]

You should have only one video decoder in graph:
...
Disable MPC-HC internal MPEG-2 decoder, add FFDShow as external filter and setup it as prefered.

I followed your advice, but the forced subtitles do not activate.

Do you have "Accept embedded subtitles" on the "Subtitles" and "Enabled" on the "VobSub" subpage checked?

That's the only settings I can think of that could affect subtitle display...

np: Laura Veirs - I Can See Your Tracks (July Flame)

The Vobsub under 'Subtitles' has to been enabled.

[tal.aloni]

VipZ,
unfortunately, that's not enough info, I didn't encounter similar problem.

The first thing to do would be to see if another player triggers the same crash, then we will know if it's related to ffdshow or not.

Tal

[tal.aloni]

PetitDragon,
thanks for clarifying,
You're using Windows 7, right?

[tal.aloni]

are official builds, like the last one from 2008, not being released anymore?

as you all can see, the recent additions to the trunk are still not stable enough to release an 'official' build.

p.s.
maybe releasing major beta versions (beta 5, beta 6) is not the best approach, because it requires extra effort on each release, and maybe it would be wiser to just mark revisions as 'stable', and promote them at the project main page.

I think 3184 is the revision I would promote there right now.

(I've used 3154 for a while, and it's very stable, no major changes were committed up to 3184, DXVA has been added with 3185)

[VipZ]

Tal, I will do a bit more digging and report back if I find anything that I can easily reproduce.

Thanks

I propose releasing 3154 as beta 7. That revision is pretty stable. There also already is an existing build for that on SF.net that we can re-use.

Tal,

Let me correct myself, as I previously stated that I didn't get garbled screens when using DXVA but no overlay. I do get garbled screens with just regular DXVA.

HOWEVER (now using rev 3259) I noticed that ff/rew did not cause garbled screens for me, however using Media Center's 30 second skip is what still causes it. I believe earlier revisions ff/rew caused it as well, but now it seems fixed. But definitely 30 second skip causes it, which would explain why those using mpc-hc do not see this.

I hope this helps!
