LAV Filters - DirectShow Media Splitter and Decoders

[VipZ]

Thanks Mercury for supplying me with test builds :)

Regarding the lip sync issue, I think it may be fine with the build Nevcairiel-LAVFSplitter-0.22-29-g5ce415f, though its the kind of thing if you look to hard you can possibly think you seeing an issue.

I will update to latest and continue testing.

[nlnl]

Plays fine.

Will you please try MPC splitter.
I have this issue (mono lpcm in m2ts) using MPC splitter fo ages! Haali works good.

And I do have the same issue using LAV :(.

[nevcairiel]

Maybe your decoder is broken. The file plays just perfectly for me. I didn't try the MPC Splitter - whats the point, its working for me.
Try using LAV Audio as well, thats what i use for LPCM decoding.

Thank you:thanks: !

You are right! MPC+LAV audio+LAV splitter work brilliant!

The problem (mono LPCM) is MPC LPCM decoder !?

Have you plans to add bitstreaming (DTS HD MA, Dolby True HD) to LAV audio?

OK I just installed this and tested it with an .mkv that Haali used to report strange fps' on... and..... it works! :)

My problem - LAV splitter does not load for .AVI files.

Haali has been uninstalled. I've boosted LAV's priority to highest....

MPC-HC reports that some AVI splitter (low merit) gets loaded instead.

Has anyone else encountered this? (Windows 7) Any tips?

[nevcairiel]

AVI is currently broken in 0.22, it'll be fixed in 0.23.

But AVI isn't all that special, using the default splitter in the time being should be fine. :)

[hoborg]

But AVI isn't all that special, using the default splitter in the time being should be fine. :)

I have problem with default OS AVI splitter and AVIs with multiple audio tracks - graphstudio/player crash when video stop.
Of cousre it is working just fine with LAVF :)

[nevcairiel]

I was more referring to the MPC-HC splitter, but sure. 0.23 will be out soon enough.

Ahh thanks for the info, I was starting to turn things upside down to figure out what was going on.

I would prefer LAV to load rather than the default :) Both in MPC-HC and in Mediaportal.

[nevcairiel]

I have one thing to finish to implement, and then some testing and cleaning, then 0.23 should be out. Hopefully i can finish it before the easter weekend.

First, I want to say I'm sorry if I report a known problem again. I don't really watching the thread closely.

I set my mouse wheel to Jump Forward/Backward (medium) in MPC-HC. LAV Spliter almost always get "stuck" when I do forward 2-3 times consecutively. It does not jump forward but jump back to the same point. On somehow related note, there are problems like video and audio getting out of sync after seeked as well. I tested with madVR and EVR Sync. I didn't have this problem last time I tried LAVSpliter. I'm not sure, but I think that was 0.19.

I remember read it somewhere that I supposed to use a special build of ffdshow but cannot find it anymore. Is that still true? Maybe that's the cause?

[disto]

Hello.Please separate LAVF Splitter from LAVAudio.If posiible could you provide two packages one for LAVF Splitter and one for LAVFAudio.Thank you in advance.

[nevcairiel]

Why?
The splitter and the decoder themself are tiny, the libraries are big, and both use them. So if i create two packages, i would have to double the libraries, thats double the size - i don't see how that is better in any known universe.

[SamuriHL]

No, I'm not in favor of separating them, either.

[Sebastiii]

me too :)

[RobertinoM]

When I am using Graphstudio and I am rendering a file..

I don't see LAV Splitter? Just for Audio I can see it. But not for Video... Is this correct?

And please keep it in one package, that keeps it simple... (to be honest, I have no idea if it is enough to extract it into one dir e.g. c:\LAV\ and then register the splitter)

Regards Robertino

Sorry, I don't have an answer to your question, but I tested it myself and found it funny that when "jumping" in MPC-HC LAV Splitter would seek to arbitrary frames instead of nearest preceding keyframe, which I asked about recently:

I don't know the technical details, although I understand that the decoder needs the previous frames in case I'm not seeking to an I-Frame. But this works just fine using Haali and Gabest. If I seek to the end of a 10 second GOP with Haali, seeking might take a fraction of a second on my quad core. With your splitter I have to watch the entire GOP from start. This also means that you can't seek to chapter starts exactly if they don't start on an I-Frame (for whatever reason).

This can now (I swear I tested it some time ago and it didn't work for some reason, probably stupidity) be done by deactivating MPC-HC's "fast seek(on keyframe)" "tweak".
So I hereby withdraw my feature request, as it can already be done. And it's even better then Haali, because it can be turned on and off.

[robpdotcom]

This isn't really a feature request, just curiosity:

Will LAVSplitter eventually be able to display the forced subs only from PGS subtitle streams? Is that even something a splitter could do, or would that be something for the subtitle renderer?

I think I understand about 70% of what you said, which make me know even less about the details, but disable fast seek like you said works great! :thanks:

Edit: A/V out of sync after seeked still happen though.
Edit2: Forcing LAV Audio Decoder solved the problem. :)

All i do is offer the information about those cue points to the player, if it uses them to do faster (yet inaccurate) seeks, its out of my hands.

MPC-HC enabled that option by default some time ago, which already caused some issues, but hey.

Thats something a sub renderer should be doing. I don't interpret any streams, i just send them to the decoders to do their magic with.

Personally, i have only seen BluRays where the forced subs are in their separate track, though. (Sadly, you cannot detect if they are forced subs just from the track. <.<)

[Hypernova]

Short question: the splitter still doesn't support ordered chapter right? I did a search and only find info about a patch.

[nevcairiel]

No it does not.

[Hypernova]

No it does not.

Thanks. Now I'll go sit and wait in the corner. :)

[nevcairiel]

I do plan to work on this sometime soon, as its a feature i would like to be able to use (also a challenge to get it working). At the latest, i want it ready when the new LOTR BluRay sets come out - the movies are split on two discs each, and my goal is to combine them in one flawless MKV, with theatrical and extended in one file. :) Normally i would just keep them on the disc, but with being split on two discs .. rather combine them! :)

This means i want to support editions/ordered chapters, what will not be supported right away is external segment linking - that is chapters in external files. I do not know when/how/if that will ever be worked on, it adds a whole extra layer of complexity - and i think its silly to begin with.

Since this is a rather big undertaking - i basically have to rewrite the MKV demuxer completly, or even a new one - i cannot guarantee anything.
Personally, i'm even doubtful that i can make it work in that given timespan.. but we'll see!

Maybe i can also join those two discs in one BluRay structure ..mmm..wonder if that works with some of the free BD authoring tools .. mmm.

[SamuriHL]

Sure. That's a piece of cake. :) I was already planning on doing 2 MKV's myself for the LOTR extended editions. But reauthoring...not an issue. :)

[nevcairiel]

Two MKVs would be the fallback solution, one for each edition. Not that i really care about the space used, but implementing that MKV features is one of the ultimate goals too (and i like a challenge)

[SamuriHL]

That'd definitely be nice. I've never made an mkv like that before.

[robpdotcom]

what will not be supported right away is external segment linking - that is chapters in external files.

What about the other type of segment linking, where the linking is done via header info? Is that any easier?

[nevcairiel]

For those building their own versions, i just commited a new properties page that lets you control the formats that LAV Splitter will demux (its alot, i already filtered and grouped some, but still alot formats in ffmpeg). It would be great if you could give it a quick whirl and see if it works.

I grouped raw audio formats (aac, ac3, dts, etc) and raw video format (.h264, .vc1, etc) into one configuration each, which did seem like a good idea at the time to keep the list shorter. Would anyone want to configure those formats separately? Is there any use-case in that? (note that raw video formats currently do not work very well anyway due to missing timestamps)

You will need to re-register the splitter to get the page to show up.
Now only left tuning the installer a bit to work with the new configuration, then i'll name it .23 and work on new things.

PS: The list is sorted by simple comparison of the name, i hope to do some sorting by importance later (have all the "cool" formats on top)

[Sebastiii]

Thanks :)

[SamuriHL]

Looks good, Nev.

[neoufo51]

Can't wait to get back AVI support.

LAV Filters 0.23

General
- There is now an installer available in addition to the trusted old .zip files!

LAV Splitter
- Added support for using the "File Source (Async)" (and others) together with LAV Splitter
- This is the new default mode for improved compatibility!
- Check release notes for additional informations.
- Added configuration which input formats will be demuxed
- Improved VC-1 in MKV playback

LAV Audio
- Fixed playback of lossless formats with huge sample sizes
- Improved A/V sync with TrueHD (and possibly others)
- FLAC decoding is now disabled by default, because the decoder is not 100% working


Download: Installer (both x86/x64) (http://files.1f0.de/lavf/LAVFilters-0.23.exe) -- Zips: 32-bit (http://files.1f0.de/lavf/LAVFilters-0.23.zip) & 64-bit (http://files.1f0.de/lavf/LAVFilters-0.23-x64.zip)

I liked doing the statistic the last time around, so here goes again!

37 files changed, 1383 insertions(+), 259 deletions(-)

First, thanks to clsid for his contributions on the installer script!

Now, the first important point. LAV Splitter and the "File Source (Async)".
You might want to start reading this post: http://forum.doom9.org/showpost.php?p=1491938&postcount=1583

I'll outline the most important facts here again, anyhow:
- Using the File Source (Async) is "better". It lets a dedicated filter do the File I/O, which is probably far more efficient. Also, its the way a splitter was designed to function (in Media Foundation, there is no other way then this).
- It'll allow you to use LAV Splitter with all files it supports, without manual media type hacking or whatnot. MPC-HC, for example, always creates a "File Source (Async)" filter, if it cannot find a dedicated file source, for all files.
- It allows more fine-grained control of which formats to use.

To adapt to these changes:
- If your player supports assigning source filters to file types, then you can still simply assign "LAV Splitter Source" to the file type, no changes for you (MPC-HC doesn't do this)
- In MPC-HC, you can add the "File Source (Async)" in the external filter list as preferred, as well as "LAV Splitter", which will ensure that they'll always be used.
- Disable all other source filters (Haali, MPC-HC internal filters), then the "File Source (Async)" will automatically take over, and LAV Splitter gets used.
- You can manually assign extensions to the "LAV Splitter Source", as a last resort.

In general, it really shouldn't be a problem, unless you have many different source filters installed, which are fighting out who gets used.

If you have problems with this, or questions, just ask.
Anyway, this will fix the AVI problem that hit 0.21 and 0.22, also fix the MPEG-TS MediaType problem Blight reported.

On the installer - its still very simple, and i'm open to any suggestions.

On the input format configuration in LAV Splitter - the list is simply sorted alphabetically, i do plan to put the important formats on top at some point. But cosmetcs .. meh, not important! :)

If you encounter any issues, as always, please report them!

PS:
As always, i recommend unregistering the old version, and re-registering the new version after installation!

[jeremy33]

Thank you nevcairiel !

Just a little question, in mpchc we have to add the "File Source (Async)" in the external filter list before or after "LAV Splitter" ?

[nevcairiel]

The order doesn't matter. You can also just try first, and see if LAV Splitter maybe "just loads".

BTW, i fixed a bug in MPC-HC that fixed the external filter list behaviour when adding the file source, you might need at least 3032 for that. But again, if you only install LAV Splitter, and disable the internal filters, it'll just work. All these things are only needed if you have multiple source filters installed. :)

[janos666]

Sorry for the stupid question but the search function didn't help to find the answer:
Does this decoder really decodes the full DTS-HD MA track or does it only decodes the simple DTS "core" (like FFDShow does)?

[Snowknight26]

Line 148 of demuxer/LAVSplitter/SettingsProp.cpp could be changed to
addHint(IDC_SUBSTREAMS, L"Controls if sub-streams should be exposed as a separate stream.\nSub-streams are typically streams for backwards compatibility, for example the AC3 part of TrueHD streams on Blu-rays.");
for consistency.

[mindbomb]

Does this decoder really decodes the full DTS-HD MA track or does it only decodes the simple DTS "core" (like FFDShow does)?

the decoder doesnt afaik, but the splitter does work well with decoders that do.

anyway, i can't get it to work by just adding the file source async and lav splitter to preferred in external filters. I'm finding that I have to make sure the internal source filters are disabled.

Also, is file source (async) supposed to be in the filters list? I just see lav splitter.

[CruNcher]

Hmm nev i didn't tested that yet though it's on my todo but in File Source Sync mode wouldn't it be impossible to work with locked files which are still data is written to, as it might be possible todo with lav splitter as source filter (depending if its aware of it) ?
also another test broke with the newer versions now nev that was (indirectly) related to the Video Stream Parsing sync issue :(

http://www.mediafire.com/?iye63xy9l5lmbq9 (black screen with new version, like as Video Stream Parsing is disabled in 0.22)

[nevcairiel]

Also, is file source (async) supposed to be in the filters list? I just see lav splitter.
In MPC-HC, you won't see it by name. But if you have one entry saying "LAV Splitter", and one entry which is just the name of the file, then that one is the "File Source (Async)". Before 0.23, that entry with just the file name would've been LAV Splitter, now you see it as a separate filter.



Does this decoder really decodes the full DTS-HD MA track or does it only decodes the simple DTS "core" (like FFDShow does)?
Since its based on ffmpeg (like ffdshow), it cannot decode more then the DTS core.


http://www.mediafire.com/?iye63xy9l5lmbq9 (black screen with new version, like as Video Stream Parsing is disabled in 0.22)

The file seems to be broken. ffplay doesn't play it properly either, and it outputs some interesting warnings on the console.

I updated ffmpeg since 0.22, which might as well have broken this. :p

[webs0r]

Installed 0.23.

Thankyou!!

[Sebastiii]

Installer is great :)
Thanks.

[edison]

is that possible add seamless playback support ? :)

[VipZ]

0.23 works very well and have now disabled my forced registry entries since no longer needed, so long to many hours of making a custom installer for filters to choose the best filter :)

Regards to sync issues in MKV, I think its a non issue now.

How does the settings in the property page affect registration, If I had to make custom options in my installer, would it make a difference if the options were in registry before or after ax registration?

[Sebastiii]

If it's was for BD, it's already working :)

Little Endian formats don't need decoding - they are just plain PCM, the same the decoder would output. Well except 64-bit float, i don't think any audio renderer supports those.

It would be much better to actually generate a proper PCM media type for those, so that no decoder is needed.

BTW, just use LAV Audio, and you'll never need to setup silly media types again - ever!

[Ger]

What cosmetic issue?
Says "mpeg2video main, yuv420p, 544x576, 15000 kb/s" for me.


Weird. Looks different for me:
http://i.imgur.com/diHgm.png
Don't worry about the window AR, I stretched it out to fit the filters menu in the window screenshot.

All(?) my MPEG-2 seem to have various weird characters now. Not sure when it started, but I used to see "mpeg2video" before too. Maybe it's some other weirdness going on with my system or a locale/cp/unicode issue, but h264 looks normal for some reason.

The screenshot is with BE mod, but I tried the regular MPC-HC trunk as well with the same results. Seems purely cosmetic though. Playback is fine. So no biggie.

EDIT: Actually, in case it helps, the third "weird" character, the "q" in that screenshot, changes. I can reopen the same file and it's something different. Character 1, 2 and 4 seems constant. Tested with MPEG-2 in .vob and .ts and a couple of different decoders.

EDIT2: Rebooted and now the fourth character is different as well. Only the first two seem to be constant. :confused:

[pankov]

I confirm the "weird" character issue.
I'm using ZoomPlayer and with v0.23 I get the same strange characters in the video stream name for MPEG2 in .ts container. For other formats or when using v0.22 everything is fine - I get "mpeg2video main".

[v0lt]

Little Endian formats don't need decoding - they are just plain PCM, the same the decoder would output.
But the LAV Splitter makes a header that is not handled correctly.

Well except 64-bit float, i don't think any audio renderer supports those.
The MpaDecFilter produces the sound on 64-bit float stream.:cool:

BTW, just use LAV Audio, and you'll never need to setup silly media types again - ever!
Check out these examples (http://www.mediafire.com/?d5l9yas32fplup2). Half of the sample noise in LAV Audio and MpaDecFilter. After my patch, most samples (except 64-bit float) are played without any problems in LAV Audio, and MpaDecFilter plays back all tracks. :p
