ffdshow tryouts project: Discussion & Development

[DeathTheSheep]

I may have reported this in the past, but I'll do so again.

Delay doesn't accept negative values. I don't think it's a good idea to default the fields to "only accepting numbers." A far better default would be to selectively disable the negative on fields where it would make no sense. There are other fields that have had this obvious problem before, such as some encoder options that actually default to negative values (like I frame quantizer shifts) but don't let the user input one!

[jhb50]

I would suggest taking another log while using GraphStudio
( http://blog.monogram.sk/janos/2009/06/14/monogram-graphstudio-0320/ )

it would also help to visually identify all the filters involved, and verify that the crash comes before starting playback (during the connection stage).

Hi Tal. The log is on pastebin "JHB50 GMA500"

I did 3 tests: Video#1.mp4 with Haali, Video #1.mp4 with MPC splitter and Video #2.mkv with MPC splitter. (see attached .grf's - rename from .zip)

The logs from all 3 are identical except for the "NAL" size, so I only pasted one.

Whats next?

Delay doesn't accept negative values.

if you want negative video delay, you can just apply positive audio delay.

negative delay is impossible when it comes to playback of live broadcast (DVB-T playback for example).

[tal.aloni]

jhb50,
when does it crash? during the connection stage, before you start playback, right?

Thanks

p.s.
this is the log I located:
http://pastebin.com/m5d7e2973

it appears ffdshow is not doing anything during the crash, but instead waiting for an external DirectShow event.
can you disable all AC3 decoders and post another log with no audio decoders?

[rsd78]

@Albain or Tal (sorry if this belongs more in the Media Control forum), but I am seeing an issue with Gabest and ffdshow dxva and Media Control within Media Center.

I can't get the context menu to pop up automatically and it does not consistently find all the embedded subtitles (I can turn off/on subs overall but doesn't usually let me select between specific languages). Thanks!

EDIT: Did more testing and using Gabest with regular ffdshow works fine with MediaControl (Context Menu pop up appears, I can see all the embedded subtitles fine and can select between them). So I'm not sure if it's a ffdshow dxva issue, mediacontrol, or Gabest. Would love for this to be worked out if there is truly something to fix, as Gabest seemed to resolve all garbling/seeking issues I had with dxva while using Haali. Note using Haali + ffdshow (dxva or regular) + mediacontrol I don't have this issue.

Thanks again for all your work.

Sorry to bump this, but I was hoping one of the great devs could take a look at this? At first I thought maybe it is a splitter/media control issue, but it seems odd that it works fine with ffdshow software decoding but not with ffdshow dxva.

Or if anyone else can confirm what I am seeing (ffdshow dxva + gabest splitter + media control) that'd be great as well.
Thanks again.

Hi Tal:

The graph is created, I saved it and attached it to the last message. Here is the .xml output from Graphedt. I then press the play Icon, the ActiveMovie window opens, then the screen goes black , and then the BSOD. I assume this means that all the connections have been made and playback has or is starting.

FOR COMPARISON PURPOSES I have also posted the log for video only using ffdshow which does play correctly. Perhaps a comparison of the two will yield a clue. They are quite different! "JHB50 GMA500Y"

Hi,
I'm using ffdshow rev3267 from this site:
http://www.free-codecs.com/FFDshow_download.htm 2010-02-13-mmx
and get a strange framerate with my NTSC-MPEG-2s.

I can open at least two NTSC VOBs via DirectShow in AVISynth which report 10000000/333667 = 29.97000002997fps instead of the correct 30000/1001 = 29.97002997fps
script1:
DirectShowSource("tenchi.vob")
info()

If I index the MPGs with DGIndex and open the D2V in AviSynth I receive proper 30000/1001:
script2:
LoadPlugin("....\plugins\DGDecode.dll")
MPEG2Source("tenchi.d2v")
info()

I'm not quite sure whoose fault this is, but I think ffdshow is reporting wrong fps for the NTSC-files. MPC reports just 29.97fps.
Can anybody confirm this issue, or am I doing something wrong?
Graphedit shows, that ffdshow is the only filter that get's active on opening the VOBs.
Or is it perhaps the MPEG2-Splitter (Win7), that gives the wrong rate?

Regards...

[tal.aloni]

John,
1. please paste hyperlinks to pastebin,
now I have to wait for google to index "JHB50 GMA500Y" :(

(you can just copy the link that you are redirected to after pasting the content at pastebin)

2. so you're saying that the computer does not crash during DXVA playback if audio is not involved?
if so, it means the crash has nothing to do with the DXVA implementation itself,
try using ffdshow audio decoder and also try unchecking "Decoder option > enable jitter correction" for the audio decoder, is it still crash?

No Tal, the "ffdshow DXVA Video Decoder" always crashes, with audio (JHB50 GMA500) http://pastebin.com/m5d7e2973, or without Audio (JHB50 GMA500 X) repasted as http://www.pastebin.com/m241b3dc6.

The "ffdshow video decoder" which does not try to use DXVA does not crash (JHB GMA500Y) repasted as http://www.pastebin.com/m2e42dece which definitely shows that it is the DXVA implementation that fails.

The BSOD screen also has the GMA500 driver DLL identified as the point of failure so "ffdshow DXVA' has certainly tried to use it.

Hi,

Too much work these days, but I finally found some time to finish the bluray subtitles implementation

Here is a test build (32 bits) (http://damienbt.free.fr/ffdshow_rev3254_20100207_dbt_bitstream_trial_beta2.exe)

Configuration : enable subtitles, and enable vobsub (cosmetic to be done). Indeed, the scaler that is used is the same as vobsubs. Then play a m2ts file (I made all my tests with graphstudio)

Status :

Working with m2ts files (from blurays). Tried with MPC splitter
BR subs in MKV : not tested, a mediatype should probably be added if this does not work
Subtitles are positioned correctly even if the resize filter is enabled
The subtitles should also be placed correctly if you enabled zooming
Zooming with smooting modes that are working : none, gaussian swscaler (full does not work yet, didn't tried the others)
The subtitles edge look a little yellow, don't know why yet
Subtitles with overlapping timestamps should be handled correctly
Performances should be checked : I used SSE optimizations but the PGS parser may require some adjustements

It's not working here in MPC-HC. No subtitles show.

Edit: Is ffdshow_rev3254_20100207_dbt_bitstream_trial_beta2.exe the correct file?

Can someone commit an update for Czech translation. It's hanging on the tracker for almost a month already and no one seems to bother with it even though the patches around it were already applied.

[albain]

I have adapted the approximative scaler to RGB32 for PGS subtitles.

There are still the bilinear and the full scaler to be adpated now.

I'll test another build when all the scalers will work and with the modifications on the interface

[tal.aloni]

Hi albain,
nice progress!

I've tested briefly, I think there are some colorspace issues with YV12, because It didn't look so good combined with DXVA.

It also crashed once when I changed the subtitle stream in the middle of playback.

I'll have time to take a look at the code later this week.

Thanks!

Hi Tal,

I have committed my changes : all the scalers work except bilinear, don't know why, it is not very important

I have renamed the Subtitles > Vobsub section to "BluRay & DVD"

The color problem you got may be due to an inversion of red and blue channels. There was a bug in the existing code, I fixed it. Maybe this is the cause.

You can grab the last revision if you want to work on it.

I haven't work yet on the subtitles stream switching issue (crash).

Thanks

Damien

[XhmikosR]

Can someone update the ICL project files? I've done it for my needs but it should be in the SVN. BTW, albain I noticed that you removed the post build event of registering ffdshow.ax. I hope you keep it that way.

[tal.aloni]

albain I noticed that you removed the post build event of registering ffdshow.ax.

albain, please do not keep it that way.

[XhmikosR]

I knew you wouldn't agree, maybe I shouldn't mention it and no one would notice it... who knows :p

[albain]

albain, please do not keep it that way.

This was not wanted. I always remove that option for my personal use

I have issues with ffmpeg-mt decoding. The file loads in MPC-HC but the file does not play. All I get is a still black frame. The time elapsed stays the same but I can seek around but the frame is always a still black frame. Libavcodec works OK.

I haven't tested it much due to lack of time but this was something I encountered on the first test with multiple simultaneous subs.

I can't seem to get a screenshot of what it's supposed to look like but the dialog is supposed to be at the bottom and the kanji title translation is supposed to be at the top.

Edit: ffmpeg-mt seems to be working in the recent build on xvidvideo.ru.

[David602]

Any plans to add FFDSHOW DXVA support for the Clarksdale architecture? Intel created an SDK to make it easier to work with.

[Sebastiii]

Hi,

I have tested subs in DXVA and also in non DXVA with FFDshow of course lol.

I have strange issue :
I use MPC Mpeg Splitter for .m2ts and MPC Matroska Filter for MKV.

For .m2ts :
The graph connect subtitle output from MPC to Text input FFDshow for m2ts with sub inside and also m2ts with no sub inside (i can verify if sub is here with mediainfo) -> but even with m2ts with sub, i can't see it and selected it :( (even if i seek the movie)

For .mkv :
FFDshow find sub (.srt or other and play it) i can select sub if we have multi file in directory but the issue that it didn't choose always the right sub) for example, i have a sample.mkv with sub inside and other files with sample2.srt toto.srt etc. -> FFDshow select sample2.srt (in this case). (DirectVobsub select only the match name).
Also when right clic on FFDshow didn't show embedded sub and to make it appear, i must seek in video and it appear.

I hope that i can explain good lol.

It's a great work :) but for now i can't see subs arf !.

Ps : To try to select, enable/disable sub, i use MRCremoteplus, i can map this option with MCE remote, i can manage enable/disable but no selection of sub, i think that i didn't find where is configured, i've try to find to show it in OSD screen but no success lol.

Also i've try with in mediaportal but, i think it was necessary to put an remote API like MCERemoteplus in mediaportal code to make it work.

Cheers,
Seb.

Hi again lol,


So this is log from debugview if it help :)

Trace from .m2ts with mutliple sub inside (no selection possible and no sub renderer)
M2TS_0001_Multisubs(not working even seek) (http://sebinternet.free.fr/M2TS_0001_Multisubs(not_working)log.rar)

Trace from .mkv with mutliple sub inside, sub only appear when i seek the video (when i go to right clic on FFDshow icon, i have the choice after but didn't render too.
MKV_[Eng-Jap] Art Of Fighting OVA (Eng-Esp sub)(Seek) (http://sebinternet.free.fr/MKV_[Eng-Jap] Art Of Fighting OVA (Eng-Esp sub)(Seek).rar)

Trace from .mkv with only 1 sub inside, sub only appear when i seek the video and disable and enable sub (when i go to right clic on FFDshow icon), i have the choice after but didn't render too.

I know that it for Bluray but i made all test posible to see why.

Anther issue also is if the OSD is enable, when i play [Eng-Jap] Art Of Fighting OVA (Eng-Esp sub) Graphstudio crash.

Convolver filter question: I tried the convolver filter inside ffdshow with impulse files here http://sjeng.org/foobar2000.html . Specifically I tried the Urei 1178 Impulse file inside the tube amps package. With Auto Adjust enabled I have very low volume compared to nearly the same level of volume as original file with foobar convolver component. When I disabled Auto Adjust I have to set the Level bar to maximum to have nearly normal volume. Is this by design?

Tested with ffdshow 3277 x86 build on xvidvideo.ru and foobar 1.0 with latest convolver component. Source audio spec: 48000Hz, 16bit, Stereo; the Urei impulse file: 44100Hz, 16bit, mono. I have tried to resample my source to 44100Hz before sending it over the convolver filter inside ffdshow, same thing happens.

[ikarad]

I try ffdshow 3277 and It crash when i select blu-ray subtitle with ffdshow.

[Sebastiii]

Hi,

I have another issue (not for subs).
I'll try to explain :
I have a sample with VC1 and DTS-HD 5.1.
If i use ffdshow (no DXVA) in decoder VC1 enable (Libavcodec) or in Post Process mode -> the sample play fine if i start from beginning, if i seek it no video but the sound is OK.
If i start it @ anytime (the time that i stop it for example @ 1 min) the screen is black (Audio OK) for video comes i must REW or FORWARD (2x).

I have try to setup only MPC video to decode it and all working OK.
If i put FFDSHOW in postprocess after MPCVideo, i have the issue.

I don't know why and i don't how to help you to find the issue (a little debugview ?).

I have check with clean GNU registry key and it's the same.
It's maybe related but i have also this :
If i use codec inside FFDshow so i use for filter resize etc. and setup libavcodec in codec section when i seek video (MPG MKV AVI etc.) it takes some second to play video (it's like a pause) -> This issue, i've it for a long time.

My bad solution is to disable libavcodec and let windows to choose another directshow filter.

I think it's not normal lol
Cheers,
Seb.

Edit : In DXVA (FFDshow) it works good when i seek and when i start in anytime in the movie.
I think TAL you have fixed it in DXVA maybe something is equal to no DXVA.
I will post a sample but i must cut it lol

Edit2 : I have made another test and when i use libavcodec, the video appear but shuttered (in MP) so the PB appear only in Post-Process and by my test in VC1. Maybe it's related to MP.

[onomatopellan]

Testing rev3277, it crash a lot when selecting the subtitles in MPC-HC. (log (http://onomatopellan.pastebin.com/m3992087))
When it doesn't crash it shows subs incorrectly, these shold be completly white for example:

http://i48.tinypic.com/24qjz15.png

Using m2ts, mkv with PGS are not detected.

BTW, how can I test using GraphStudio? Which splitter/source filter I need? Haali doesn't work with PGS subs.

[albain]

For Haali this is just a matter of media type.

If you have a sample somewhere I will be able to add the support

About this strange white edge around subtitles, which colorspace is used in output of ffdshow ?

I made all my tests in RGB32, so there may be issues in YUV mode (used by DXVA for example).

Graphstudio is equal (for me) to MPCHC : I use MPC mpeg splitter (standalone filter), then ffdshow then EVR

EDIT : I can confirm, bluray subtitles won't appear with YUV colorspace. While I fix it, you can disable YV12, NV12, and all YUV colorspace in ffdshow output section.

I don't understand why these colorspaces are enabled by default as they give lower quality than any RGB colorspace

[onomatopellan]

Yes I'm using ffdshow DXVA so the output is NV12.

I don't have bluray so I've made an m2ts with tsMuxeR from this sample:
http://ftp.touchpointdata.com/PaperHeart_Sample.mkv

[Sebastiii]

I have found that some .m2ts didn't work and other work with MPC Mpeg Splitter.
For test i have try with MPC-HC and mediaportal to see.
So i think this is a splitter issue :
Link to test sample :

1- Sample_SUB_OK.m2ts (http://sebinternet.free.fr/Sample_SUB_OK.m2ts)
2- sample_multisub_new.m2ts (http://sebinternet.free.fr/sample_multisub_new.m2ts)

I don't how to open ticket for this to MPC-HC dev.
Thx,
Seb.

[Sebastiii]

Yes I'm using ffdshow DXVA so the output is NV12.

I don't have bluray so I've made an m2ts with tsMuxeR from this sample:

Hi,

With your sample and with MPC-HC it didn't see subtitle.
With mediainfo sub is here.

I'm lost lol

[onomatopellan]

EDIT : I can confirm, bluray subtitles won't appear with YUV colorspace. While I fix it, you can disable YV12, NV12, and all YUV colorspace in ffdshow output section.

you are right, now with rgb output ffdshow shows the subs correctly.

@Sebastiii: It's a sample from xbmc team I have used to extract the PGS subs and make a .m2ts sample, and in mpc-hc doesn't work yet. With last xbmc you should see the subs though.
EDIT: I think it's the same splitter but they fix something for accept mkv with PGS.http://trac.xbmc.org/ticket/8429

[Sebastiii]

Ok so it's splitter issue (MPC Mpeg splitter) and xbmc do you know what it using ?
Thx :)

Damien, do you see sub from the sample with MPC and RGB32 output ?

[ikarad]

For Haali this is just a matter of media type.

If you have a sample somewhere I will be able to add the support

About this strange white edge around subtitles, which colorspace is used in output of ffdshow ?

I made all my tests in RGB32, so there may be issues in YUV mode (used by DXVA for example).


I use YUY 2 and I have strange colors for subtitles

[cyberbeing]

I don't understand why these colorspaces are enabled by default as they give lower quality than any RGB colorspace

First, some things FFDshow needs to connect to may only accept something like YV12, YUY2, or NV12. Also keeping video in it's native color-space should always be the default unless the user explicitly forces a different colorspace.

Secondly, conversion to RGB takes a lot of additional processing power especially on 1080p video.

Dual-core Athlon X2 2.6Ghz using ffmpeg-mt for decoding 1080p h.264:
YV12 CPU Usage: 40-50% of both cores
RGB CPU Usage: 60-70% of both cores
RGB HQ CPU Usage: 70-80% of both cores

Dual-core Athlon X2 2.6Ghz using libavcodec for decoding 1080p h.264:
YV12 CPU Usage: 70-80% of single core

This must be my fault, DVD (subs+menus) and bluray subs share some parts of code

I have brought some fixes in rev 3282 but I am not sure this will be anough

Can you tell me which colorspace do you have in output ? (mouse over ffdshow video icon)

YUY2 - i have here Intel(R) 82945G Express Chipset Family (i945G0)
RGB32,YV12,... have same issue

First, some things FFDshow needs to connect to may only accept something like YV12, YUY2, or NV12. Also keeping video in it's native color-space should always be the default unless the user explicitly forces a different colorspace.

Secondly, conversion to RGB takes a lot of additional processing power especially on 1080p video.

Dual-core Athlon X2 2.6Ghz using ffmpeg-mt for decoding 1080p h.264:
YV12 CPU Usage: 40-50% of both cores
RGB CPU Usage: 60-70% of both cores
RGB HQ CPU Usage: 70-80% of both cores

Dual-core Athlon X2 2.6Ghz using libavcodec for decoding 1080p h.264:
YV12 CPU Usage: 70-80% of single core
RGB CPU usage: >100% of single core (unplayable)
RGB HQ CPU usage: >100% of single core (unplayable)
And moreover, some filter like TIVTC or decomb works only with nv12 or YUY2 ant not RGB

What? I use TIVTC with RGB output every day. It works fine.

Edit: Clarification.

Same problem here. Reverting to 3274 fixed it.

Sorry, in fact, It's Telecide that doesn't work with rgb

For tivtc on the official page, the author speak about only the support of yv12 and yuy2.

Everything should be fixed in revision 3283 :

- DVD menus
- Bluray subs with YUV colorspaces
- MKV support for bluray subtitles

There is a bug in Haali splitter (or rather a support to be added) : the PGS subtitles don't have any media subtype in the output pin of Haali's. Don't tried with MPC matroska splitter

TODO/TOFIX :
- Bilinear scaling in RGB mode (only bluray subs may use this scaler)
- Bluray subtitles support from file (.sup)

Thanks albain. Now subs are shown correctly with ffdshow DXVA (subs are completly white on my sample), but MPC-HC still crash a lot when I select the subtitle of the .m2ts file. (with Haali and with Matroska internal filter)
