LAV Filters - DirectShow Media Splitter and Decoders

[dann23]

And I have another feature request. is it possible to make a configuration file where to specify for what formats to register?
Also I found a bug. If I'm using ffdshow dxva, I can't choose external subtitles and no external subtitle is used. If I'm not using dxva mode than external subtitles works but I can't choose the right one (I have some subtitles in the same folder as my movie).

[nevcairiel]

Is it possible to add support for amr and bink files?
Sample files?

Hi nevcairiel,

Could I humbly inquire if you have any update on the status of LATM AAC (http://forum.doom9.org/showthread.php?p=1427013#post1427013) support in LAVFSpitter?

I didn't really put more work in it so far. I can try again, but it proves to be quite difficult as libavformat doesn't understand it either.

And I have another feature request. is it possible to make a configuration file where to specify for what formats to register?

This will be in the config GUI.

Also I found a bug. If I'm using ffdshow dxva, I can't choose external subtitles and no external subtitle is used. If I'm not using dxva mode than external subtitles works but I can't choose the right one (I have some subtitles in the same folder as my movie).

External subtitles are not handled by the splitter, so i would vote for a ffdshow bug.

Thanks. :o Any efforts you can put in that direction, when you have the time and inclination of course, would be greatly appreciated by many I'm sure.

I must admit I got my hopes up perhaps too quickly when I saw this thread because the only applications that can understand and work with my TS files, and the LATM audio, are VLC and Handbrake which I tend to associate with libavformat/libavcodec (rightly or wrongly) but that probably doesn't mean anything.

And about the settings that will be in the GUI it's fine. but if I'm using regsrv32 to register the filter, how can I specify for what types to register before doing this?

[nevcairiel]

You can't. But after registering you can open the properties page (once its implemented), and turn off the formats you don't want it to handle.
It'll still be registered for those formats, but when a player tries to use it for a mkv file, and you turned mkv off, it'll just fail silently, and the player will try the next source filter.

Thanks, effectively it would be great :)
I always have pb with Mediaportal :( i try like we suggest with Tourettes but it doesn't work well too :(
I don't know how to help on this. I try on many version i have (for mediaportal final and svn and LAVF latest source too).
But i have also this issue with MPC-HC many times the video don't start and the player is freeze.
I suppose it's on splitter side and no Libavformat but i'm not sure too.
Again :) it's really appreciate the work you made m8 :) and also alone.

[Virtual_ManPL]

It works fine here with the latest git.
Odd, in my case I use MPC-HC internal decoders & external Xvid and I can't get LAVFSplitter to work with AVI files.
Can you or someone confirm this ?

[Virtual_ManPL]

nvm guys, I find finally what causes it

http://github.com/Nevcairiel/LAVFSplitter/issues/#issue/25

[nevcairiel]

Why can't everyone just speak english. =(
I probably know how to fix it, will try when i get home later today.

In related news, my time has been somewhat occupied with other projects that had an approaching deadline, and probably will be for at least a couple more weeks.

I'll release the last version i'm comfortable with as 0.10 soon, to fix more media playback issues. Guess stream/language selection has to wait again.

@nevcairiel

Will you add the support for ArcSoft Audio Decoder HD (TMT2/TMT3) to decode DTS-HD (and TrueHD) to LPCM? The trick in this post (http://forum.doom9.org/showthread.php?p=1446017#post1446017) works fine for DTS-HD decode with any DirectShow player + MPC MPEG Source (Gabest) + ArcSoft Audio Decoder HD (my own test (http://www.avsforum.com/avs-vb/showthread.php?p=19282099#post19282099)).

MPC MPEG Source (Gabest) + ArcSoft Audio Decoder HD does not work for TrueHD decode (silent). In the same split: MPC MPEG Source (Gabest) presents TrueHD as MEDIASUBTYPE_DOLBY_AC3 {E06D802C-DB46-11CF-B4D1-00805F6CBBEA} and the Arcsoft Demuxer presents the stream as {4288B843-610B-4E15-A53B-43007FCFF614}. So I opened MpegSplitter.ax in a hex editor and replace the two occurences of the hex string "2C806DE046DBCF11B4D100805F6CBBEA" with "43B888420B61154EA53B43007FCFF614" in the file. This worked to some extent, but not perfect...

[nevcairiel]

I already added support for using the ArcSoft decoder for DTS. TrueHD has another special media type as well?

[SamuriHL]

Yes, and it doesn't pass it properly in its own chain, either. MKV's, for example, won't play with TrueHD sound. I've reported it to ArcSoft so maybe that'll eventually get fixed.

[renethx]

I already added support for using the ArcSoft decoder for DTS. TrueHD has another special media type as well?
Hmm, lavf dshow source filter (v0.9) never connects ArcSoft Audio Decoder HD (TMT3) directly. :confused: It still presents DTS-HD as MediaSubType_DTS, the same as MPC source filters for DTS-HD, which is not a media subtype supported by AS decoder. Hex edit (http://forum.doom9.org/showthread.php?p=1446017#post1446017) makes it connect to AS decoder. DTS (non-HD) in DVD is fine with lavf dshow source filter/MPC source filters + ArcSoft Audio Decoder HD.

ArcSoft Demuxer presents TrueHD as {4288B843-610B-4E15-A53B-43007FCFF614}, while lavf dshow source filter/MPC Mpeg/Matroska source filter presents it as MEDIASUBTYPE_DOLBY_AC3 {E06D802C-DB46-11CF-B4D1-00805F6CBBEA}. So these filters won't work with ArcSoft Audio Decoder HD for TrueHD. These source filters still connect to AS decoder because MEDIASUBTYPE_DOLBY_AC3 is one of the supported media types of AS decoder (for AC3, not for TrueHD).

[nevcairiel]

It was added after 0.9 :p MEDIASUBTYPE_DTS2 is it, btw

In any case, why use ArcSoft for TrueHD?

[renethx]

I am not pretty sure about this point. For example, suppose that a user with an analog sound card wants to play M2TS/MKV files with HD audio tracks, TrueHD or DTS-HD. So he has to use both ffdshow and ArcSoft, with DTS support in ffdshow disabled and placing ArcSoft below ffdshow in external filters in MPC-HC. Further if a file contains multiple audio tracks, say AC3 primary and DTS secondary, then ffdshow is connected and changing audio to DTS later would result in no sound, I guess.

Using ArcSoft for the BD/DVD audio codecs and ffdshow for the rest is perhaps less troublesome.

[nevcairiel]

Actually switching audio tracks re-negotiates the audio codec thats being used with LAVFSplitter, so it would work switching around later.
Anyhow, i'll test with a truehd track.

[nevcairiel]

I implemented the ArcSoft TrueHD subtype today, seems to be working fine.

[renethx]

Great! Thanks.

[Sebastiii]

Nice :)

[SamuriHL]

Can you send the code to ArcSoft now? :D

[renethx]

OK, another request. :) For LPCM audio tracks, LAVFSplitter can't connect to ArcSoft Audio Decoder HD. If this is fixed, we can use ArcSoft Audio Decoder HD exclusively to ouput all BD audio codecs by analog, I think.

[rica]

As far as i understand it can not use "Open DVD" option; you should use "Open File" option on MPC-HC?

In this case Arcsoft MPEG Demux already done the job:

http://forum.doom9.org/showpost.php?p=1448413&postcount=49


_ _ _ _ _

[nevcairiel]

No you cannot use the Open DVD option. It would be cool if that worked, but thats not how it is right now. ;)
With the internal MPEG Splitter in MPC-HC you can open the index.bdmv file to get seamless branching to work, at least.
I'll try to implement this at a later date as well.

@renethx:
You wouldnt happen to have the LPCM media type arcsoft uses, would you?

[renethx]

You wouldnt happen to have the LPCM media type arcsoft uses, would you?
ArcSoft MPEG Demux presents LPCM as

MEDIATYPE_MPEG2_PES
{697AD091-7F64-43CC-86B0-5D190A372E2E}.

But replacing HDMV_LPCM_AUDIO {949F97FD-56F6-4527-B4AE-DDEB375AB80F} with {697AD091-7F64-43CC-86B0-5D190A372E2E} in MPC Mpeg Source (Gabest) does not work, but replacing HDMV_LPCM_AUDIO with MEDIASUBTYPE_DVD_LPCM_AUDIO {E06D8032-DB46-11CF-B4D1-00805F6CBBEA} works.

[nevcairiel]

You mixed up mediatype and media subtype here. I'll run som tests, i guess.

Where to get correct avconfig.h? Here (http://git.1f0.de/gitweb?p=ffmpeg.git;a=summary) it is not.

[v0lt]

I took a avconfig.h from the mpc-hc project.

But there was another error:
1> LINK: fatal error LNK1104: cannot open file 'avformat-52.lib'

[nevcairiel]

You have run the build script i supplied. It creates the avconfig and the library its looking for.

[v0lt]

You have run the build script i supplied.
I have not done this? What is it called?

What to do with it?
Visual Studio 2010 can not do anything with them. Quest?

[Kurtnoise]

You have to run it through MinGW/Msys...

I believe it's written in the ReadMe file.

[nevcairiel]

I prefer the second method, it doesn't require a special decoder to handle the subtype.

I'll apply all of those "soon", been busy with other projects (that pay money, ha!)

[v0lt]

The second method works only with AC3Filter.
Probably will work through ffdshow. But there I do not like it RAW-decoder.
Built-in windows PCM-decoder does not work. Why is unclear.

IMHO, it is necessary to convert big-endian to little-endian in the splitter. But I do not know where yet.

Nevcairiel you are assigned to this bug in mpc-hc
https://sourceforge.net/apps/trac/mpc-hc/ticket/48#comment:14

MPC-HTPC told me that your lavssplitter take care of this bug.
Hi ikarad,

IMHO nevcairiel was put as owner of the ticket you opened on the trac because he is working on a new spillter (LAVFSplitter (http://forum.doom9.org/showthread.php?t=156191)), which should be integrated into MPC-HC once it is finished (but according to nevcairiel don't expect anything this year). Anyhow, this is the reason why all splitter related issues on the trac were assigned to nevcairiel. So maybe when LAVFSplitter will be integrated into MPC-HC your problem is solved, but until then you either have to be patient or just install the current beta builds of LAVFSplitter.
Is-it true? and is-it corrected with beta version of your software?

[nevcairiel]

Well. How are the subs represented in the file? Is there 2 streams that should both be active? Or is it one subtitle stream?

If its one stream, the sub renderer is to be blamed, not the splitter. If its two streams, i guess we need to figure out a way to allow people to activate multiple subtitles.

there is 2 differents subs that should both be active in the same time but I don't know what means 2 streams.

It's doesn't worked with mpc-hc since the start of support of pgs subs in mpc-hc. Although it works with news sub renderer in ffdshow.
