Windows 7 Professional 64bit GeForce GTX 580, no problems with official 0.24 or LAVFilters-0.24-spdif-test1 build. Can anyone else using Zoomplayer reproduce the problem?

Thanks for all your hard work nevcairiel.

[SamuriHL]

Nev, are you planning on turning on static linking for mfc? Given the conversation in the MPC thread it seems to make sense to do that, yes?

It's working for me, everything about my setup is similar except I have an ATi card. Same versions of ZP and LAVSplitter (I'm not using LAVAudio at the moment though).

[FreeFall]

Mark_A_W,

Thanks I figured out the cause of the crash, Zoomplayers Internal Audio Stream Switching Filter was the problem. I have it disabled now and everything is working again.

Sorry nevcairiel, I'll report the problem to Zoom's developers.

I've been using LAV splitter instead of the Haali packaged with CoreAVC 2.5.5 + Arcsoft Audio HD (for trueHD/DTS-MA audio).

I have 4 questions:

1. I'm curious if there are other people who use LAV for instead of Haali for CoreAVC (H.264 video decoding); and, why LAV may work better (or worse) under certain cases.

2. Does the LAV audio decoder provide true DTS-MA and TrueHD audio decoding (to be used with CoreAVC video)?

3. Can I use the following containers for (H.264+DTS-MA/TrueHD) with the LAV splitter: MKV, M2TS, TS, MP4?

4. Are there any benefits to using the LAV audio filter instead of other HD audio decoders such as ArcsoftHD and FFdshow? Im guessing maybe the LAV audio decoder was intended to work better with the LAV splitter for HD audio (DTS-MA/True-HD)? Honestly, I would prefer to use LAV audio decoder if it has benefits over the commercial audio decoder from TMT Arcsoft.

Thanks for any friendly/userful information that can be offered.

MKANET

[nevcairiel]

There is an improvement I can seek almost anywhere in it but the very end. Everything past 4:36 is unreachable ... even worse is that the video and audio stops at that moment and only the timeline continues till 4:57 (for 20 seconds more).

Aww. Too bad, guess i need to give it another go. I might have an idea, however.
One question though, do the last 20 seconds play properly when you seek to just before the point of breakage? Or was that what you meant with "stops at that moment"?

What i fixed earlier was just seeking, it might still fail to work to playback properly, i wasn't 100% sure on that fact.


Thanks I figured out the cause of the crash, Zoomplayers Internal Audio Stream Switching Filter was the problem. I have it disabled now and everything is working again.

Sorry nevcairiel, I'll report the problem to Zoom's developers.

Feel free to point them here, there must be something i changed that caused it, and i can probably remedy the problem if they can tell me whats doing the crash

Nev, are you planning on turning on static linking for mfc? Given the conversation in the MPC thread it seems to make sense to do that, yes?
Undecided.


2. Does the LAV audio decoder provide true DTS-MA and TrueHD audio decoding (to be used with CoreAVC video)?

Neither LAV Audio nor ffdshow provide true DTS-HD MA. It does do TrueHD lossless though.
Unless you're bitstreaming, then LAV Audio can send the full DTS-HD MA untouched to your receiver.


3. Can I use the following containers for (H.264+DTS-MA/TrueHD) with the LAV splitter: MKV, M2TS, TS, MP4?

I have never seen HD audio content in MP4, but sure, i don't see why those wouldn't work.


4. Are there any benefits to using the LAV audio filter instead of other HD audio decoders such as ArcsoftHD and FFdshow? Im guessing maybe the LAV audio decoder was intended to work better with the LAV splitter for HD audio (DTS-MA/True-HD)? Honestly, I would prefer to use LAV audio decoder if it has benefits over the commercial audio decoder from TMT Arcsoft.

Like i said earlier, neither ffdshow or LAV Audio offer DTS-HD MA decoding. Only the TMT decoder does.
If you're using LAV Splitter, and you don't need all those fancy post-processing options in ffdshow, i would recommend using LAV Audio for everything except DTS, and use the TMT decoder for that.

[mkanet]

To be honest, I really dont like FFdshow. I dont have it installed on any of my PCs. As you might tell from my responses, I've only use ArcsoftHD for all my HD audio needs in directshow players (TrueHD/DTS-MA in all popular containers with H.264).

And, yes, I do use bitstreaming since I dont have external decoding outside my PC... just analog 5.1 outputs.

I probably should have rephrased my questions a little bit. More specifically. I'd like to know what the difference between LAV audio TrueHD decoding is compared to TrueHD audio in Arcsoft HD. If there isn't any, I'm going to keep things simple and continue to use the Arcsoft 3 HD audio filter (with 24bit 96Khz or higher audio).

I'm guessing LAV splitter is the most flexible, bug-free splitter for M2TS, TS, and MKV that contain DTS-MA/True-HD; even more than the latest Haali build packaged with the latest CoreAVC H.264 video decoder and the gabest HPC-HC splitter.

It would be nice to have real DTS-MA audio support in LAV audio filter; which would eliminate the need for Arcsoft Audio HD decoder and ffshow.

Thanks again for all your help,
MKANET

[nevcairiel]

I haven't used the TrueHD decoder in the ArcSoft HD Audio Decoder, but its dts decoder is doing fine, so i figure their TrueHD will probably be good too.

[FreeFall]

nevcairiel,

Reported the problem and directed them here.

Thanks.

[Andy o]

Nev, LAV Splitter is not connecting to the Arcsoft HD decoder for E-AC3. Either I get both the Arcsoft and the Microsoft DTV-DVD decoder, and get stereo noise (like crackling), or if I block the MS DVD decoder, I get nothing and no audio. With the MPC splitter it does connect, but weirdly it only decodes 7.1 into 5.1, so maybe it's reading the AC3 part only. From TMT3 it does decode 7.1 E-AC3 properly.

[Andy o]

Re: Arcsoft HD decoder... I loaded the HD decoder from TMT5's installation without the necessary dll and it works right there, decoding 7.1 DTS-HD. Is this new, or that dll isn't necessary for this?

EDIT: this information is wrong, sorry.

[nevcairiel]

The MPC-HC splitter reports E-AC3 streams as AC3, so that would explain it. Not sure what media type the ArcSoft decoder expects - does ArcSoft have a splitter that one can use to see what subtype it uses?

Also, you do have the required dll for E-AC3 decoding, right?

[Andy o]

yeah, I actually just used the TMT3 installation folder, didn't have to download the necessary files, just that custom checkactivate.dll. I don't think Arcsoft's splitter can be used externally though.

[Sebastiii]

Hi,

This is my result test for yesterday.
I have found and solve the blackscreen issue i have when i start/stop/change subtitle/audio with my ASUS Nvidia 460 card.
I have also made a workaround to solve my refresh rate issue with my HK AVR-355.
I have also fix the audio flush (appear more on NVIDIA than ATI with HK AVR-355.

How i solve this, it's a bit tricky lol.

I have connect on output NVIDIA DVI/HDMI a splitter HDMI (one in and two Outputs)
One Output goes to my VP (Sanyo Z3000)
Second Output goes to HDMI1 Input of my AVR.

Now i can refresh with no issue because i bypass my AVR :) (it's not normal but hey i want something that work).
But if nothing is connected on Output HDMI of my AVR (i can't get no sound).
I made this to solve it : I connect Output HDMI (AVR) to HDMI2 Input, like this my avr think something is connect (Idiot HK).

The last thing to do is to change "monitor device" by the override HK (inf) to fake windows that believe that my Z3000 is my AVR.
I know it's really !!!!!!!!!!!! hard this setup but it works :)

My blackscreen issue is due to this setting in NVIDIA control pannel (screenshot is in french) but to fix it is to set to Video Fullscreen (Videos plein ecran :
http://dl.dropbox.com/u/10536084/Lav/Nvidia_Blackscreen_Fix.jpg

My audio vanishing issue was fixed on installing : http://dl.dropbox.com/u/10536084/mp/HdmiYo-0.1.1.msi and http://dl.dropbox.com/u/10536084/mp/ReadMe-0.1.1.rtf
When my avr didn't detect sound, i made ctrl+space to reset HDMI :) and the sound goes on.

Now that my HTPC start to be working like it does lol, i can retry all my sample and see why i have crash :).
Regards,
Seb.

I have always had it set to "Auto" and it worked just fine.

But if it works for you, all is good!

[Sebastiii]

Thanks,

I have retry to set in Auto yesterday and issue goes back, so Video fullscreen is my new friend :)

[pankov]

Aww. Too bad, guess i need to give it another go. I might have an idea, however.

What i fixed earlier was just seeking, it might still fail to work to playback properly, i wasn't 100% sure on that fact.
Thanks in advance.
The last 20 seconds are "unplayable" and "unreachable". The audio and video just stop at 4:36 - only the timeline continues to move.
In the original (bigger file - I've put it on the FTP so you can test if needed) if I seek (click on the timeline) past the 4:36 line I see one or two decoded frames as still images when using LAV CUVID Decoder. If I use CoreAVC instead I get high CPU usage (4 cores @ 100%) for a few seconds and then nothing - no decoded frames.

[nevcairiel]

Those symptoms are in line with the idea i had, sounds good.

[pankov]

:)
Looking forward for fix then
;)
btw
sorry for taking your precious time with such problems. If you prefer you can ignore them for a while and do more important stuff ... I do understand the .ts is a bad container and my recordings are somewhat flawed (if it matters I didn't use the new version of the DVBViewer which strips some H264 packets if they are empty)

[nevcairiel]

Don't worry, should be an easy fix, if my theory is right. I usually sit at work and browse code thinking about problems when i get bored, can't really tackle any big tasks in those short periods. :p

Besides, i'm done with big tasks for 0.25, so ironing out some bugs, giving it a few days to breath before the release (which might happen this evening).
I really powered through code for 0.25 (1500 new lines or so, going to post stats with the release), so some debugging and tracking is some welcome alternative. ;)

[Andy o]

Also, you do have the required dll for E-AC3 decoding, right?

As it turns out, the arcsoft mkv splitter can be used, but it doesn't connect the e-ac3 streams either. I can't find the TS splitter. Any idea where it might be, or what's its file name?

[nevcairiel]

I found a subtype somewhere, not sure how accurate it is, but going to try it when i get home

For reference, so i dont lose it.
DEFINE_GUID(MEDIASUBTYPE_ARCSOFT_DDPLUS ,0x71cfa727, 0x37e4, 0x404a, 0xae, 0xc0, 0x34, 0x84, 0x25, 0x32, 0xef, 0xf7);

you can check in MPC-HCs external fitler list if the ArcSoft decoder lists that subtype
Would look something like this
{71cfa727-37e4-404a-aec0-34842532eff7}

[Andy o]

aargh apparently makeMKV doesn't remux the E-AC3 streams. They show up there, but they don't bitstream as they do with m2ts. Anyone knows how to remux e-ac3 streams into mkv? tsmuxer doesn't recognize e-ac3 either.

Anyway, this is what MediaInfo tells me on the 7.1 e-ac3 m2ts:

[nevcairiel]

Looks like the stream is severely broken. 4 channels? :D
eac3to should be able to extract the track (its named eac3to afterall), and mkvmerge should manage to put it back in.

[Andy o]

Should be 8 channels though, so both are technically wrong on that account only that one is wronger. I'll see what I can do with eac3to, thanks.

[madshi]

Access Violations inside another DLL cannot be caught, at least i wouldn't know how. If anyone thinks he does - feel free to lecture me or point me to a resource to learn. :d

Yeah thats probably a bit too much. rather would've something along the lines of a try..catch construct.
There are these constructs, using __try {..} __except () {...} but those didn't seem to work if the segmentation fault came from ffmpeg (i just dereferenced a null pointer for testing in some function)

Going to try something else, but then i still think i rather want to know about crashes in ffmpeg, because they should never happen.
And really, i havent seen a crash for ages.

eac3to should be able to extract the track (its named eac3to afterall), and mkvmerge should manage to put it back in.

eac3to 3.24 is only showing me the ac3 audio:

2: AC3, English, 5.1 channels, 640kbps, 48kHz

From its description, it doesn't seem to extract e-ac3, perhaps madshi can chime in on this...

There are these constructs, using __try {..} __except () {...} but those didn't seem to work if the segmentation fault came from ffmpeg (i just dereferenced a null pointer for testing in some function)
"__try {...} __except(1)" should work just fine, if you put it around the actual call of the exported ffmpeg API, and if ffmpeg doesn't catch/handle the exception itself. This will work only if the exception occurs directly in the called ffmpeg API, though (or in a sub function). It will not work if the exception occurs in a private ffmpeg thread, of course.

[Andy o]

madshi, can eac3to demux E-AC3 from a m2ts container?

[hoborg]

Hi.
I am not sure if this is LAVF splitter issue...

If i try to render "http://www.luckymedia.nl/luckytv/wp-content/uploads/luckytv_video/2011_05_05_4dc2e404d86b5.mp4" file using "File Source (URL)", it will popop -2147221163 - in Hex is 80040155 which seems to be the error code for: "Interface not Registered". This happend in Media Portal OnlineVideos plugin.
Using official LAV.24

If i use Haali splitter, it is working.
Ideas?

http://www.mediafire.com/?pi6ev8wagqaaq2u

When played with LAV splitter + LAV audio decoder the sound mutes after a few seconds.
When played with LAV splitter + MPCHC AMR decoder the sound plays just fine.

There is some feature in that file thats not supported by the ffmpeg amr decoder (something they call "dtx mode").

ffmpeg supports using a 3rd party decoding library, opencore-amr, for amr decoding. I can try to add it to my ffmpeg build, for better format coverage.

Yes, at least if it's muxed correctly.

Thanks,

[nevcairiel]

I have all those sample files. I will test them again, but i have not seen any ffmpeg crash for a long time, looks more like media portal is screwing up again, or your system is somehow faulty.

Most of these errors look like heap corruption errors, which would not necessarily have to happen at the point when it crashes, it could just crash when the corrupted heap is accessed the next time.

Try with MPC-HC, and if you cannot make it crash, i blame MediaPortal.

[Andy o]

What does "eac3to source -logpids" say?

Yes, at least if it's muxed correctly.
It's straight from the Dolby Demo blu-ray. From the same m2ts, DD+ is bitstreamed and decoded perfectly with LAV Audio.

[SamuriHL]

jmone didn't believe me when I said I couldn't get eac3to to extract the eac3 from certain discs, either. It would convert it to AC3 in my case.

[Andy o]

When I extract as .ac3 though, mkvmerge sees it as a h.264 elementary video track, so I get 2 video tracks and no audio. Weird.

Anyway, I uploaded the m2ts here if anyone wants to give it a go:

http://www.megaupload.com/?d=A18UUKPN

Oh, I didn't know we're talking about a > 5.1 DD+ track. These tracks actually consist of a 5.1 AC3 core with E-AC3 extension packets for the additional back channels. This format is not supported by eac3to, because there's only one Blu-Ray that has *ever* used this format - the Dolby Demo Blu-Ray. To my best knowledge there's not a single movie Blu-Ray out there world wide that is using this format. So adding support for this would be a total waste of time, IMHO.

[clsid]

Going to try something else, but then i still think i rather want to know about crashes in ffmpeg, because they should never happen.
And really, i havent seen a crash for ages.My suggestion of catching the exception was not to hide the crash from the user, but rather to display a more explicit error message, and of course to end the process more gracefully.
When a crash happens, it is for most users not directly obvious what part of the playback chain was faulty. A custom error dialog could allow you to clarify which filter crashed and at the same time ask the user to report the problem with a sample file.

[nevcairiel]

That could work, i guess.

[Andy o]

This format is not supported by eac3to, because there's only one Blu-Ray that has *ever* used this format - the Dolby Demo Blu-Ray.

lol I was gonna say, the good news is that this is about the only blu-ray with DD+.

[SamuriHL]

But there are HD dvd that support it, and if we want to extract those with eac3to, we're apparently SOL...

[Andy o]

Are there any 7.1 E-AC3 HD-DVDs though?

[Sven75]

As promised before here I am with 2 PowerPoint issues.

Nev, maybe you can figure out what is happening here (if you are bored and find some time to look at it).

It's a bit of work to set up the testing environment, but I hope that you don't mind:

PowerPoint versions <= 2007 by default use MCI to playback videos. I tweaked the MCI settings in the registry to use DirectShow instead of vfw.
Also, PowerPoint 2007 tries to use wmp.dll to handle videos - hardly with success. I therefore always de-register the 32 bit version of the wmp.dll.

http://www.mediafire.com/?lfro1w3nd3bidib (registry tweaks for MCI)


The first one is for PowerPoint 2003/2007:

This exemplary flv file somehow starts to "play" (there is definitely some activity) but it seems that the screen is just not being updated. This only happens with LAVSplitter. MPC-FLV-Splitter and another one I tried do not suffer from this issue. (Btw, decoder is current ffdShow 3840)

The second problem is with the hardware accelerated native mode of PowerPoint 2010. I know that you don't have version 2010, but the standalone viewer should show the same behaviour. It is only the following mpeg file (found so far) which cannot be played back at all with LAVSplitter in PowerPoint 2010. I tried the elecard mpeg demuxer instead and it works fine. (Tried ffdShow and MS DTV-DVD as decoders but no difference)

As far as I know, in native 2010 mode PowerPoint at first tries to use DXVA to playback videos. Could the underlying problem be a colorspace issue?

Are there any 7.1 E-AC3 HD-DVDs though?

I'm not at home to check but I believe so.

I remember when I built my 7.1 system back in the day I was eager to try 7.1 HD-DVD's and I think the only I could find was Pan's Labyrinth which is DTS-HD MA.

Regardless of the 7.1 issue, there are discs that eac3to only converted to ac3. I'll check on those later.
