LAV Filters - DirectShow Media Splitter and Decoders

[Underground78]

I found the problem with TS file durations, was kinda a "oops" on my side, heh. :)
And like expected seeking is working fine with the proper durations.

Great ! :)

@Ger:
Man that zSHARE page is a mess.
Still downloading.... previously it just stopped at 20% or so and i had to restart. If it does that again, screw it =P
How about splitting the files and uploading to rapidshare or something?

I'll try to create multipart rars < 150 MB or something like that, and upload to sharebee (which should distribute to several other services). But it will take a few hours because of my slow upload speed.

I finished the download now, so don't worry about it.

Regarding your files:

LATM AAC is not supported by libavformat at all right now, someone will have to implement this, so no deal on audio. Trying to get subtitles to work, but ffdshow subtitle renderer doesnt even connect to the DVB subtitles, wonder if MPC does..

[Ger]

MPC-HC does show DVB-subs (Casimir added this not too long ago IIRC) with the internal splitter, but wrong background color (green instead of semi-transparent grey in the John Adams sample). That is probably not a splitter issue though. DVB subs with a fully transparent background (Bulgarian etc. in the Henry IV sample) seems OK with internal splitter/renderer (not tested thoroughly though).

TTX subs probably need a Teletext decoder, which I doubt MPC-HC has currently, but it would be nice if the splitter identified both the DVB and TTX subtitle tracks correctly anyway.

[nevcairiel]

I'm just having it ignore TTX for now, as i don't really know what to do with them.

EDIT:
DVB subs work, yay.
Now i just need to find the difference in the flags for your hearing impaired thing and i'm all done.

EDIT2:
Ok, i arrived at that sample with subs in both DVB and TTX, but how exactly am i supposed to figure out if its a TTX sub or some other TTX stream that i don't want to show?
This puzzles me! For now i'm just showing the 3 DVB sub tracks.

[tetsuo55]

You guys could use megaupload.com in the future, it offers a high upload and download speed and supports files up to 1gb iirc

It's over my head, but if you look at the "Whatever works" sample in VLC, or the screenshot I've included, VLC can tell the difference between TTX index pages and TTX subtitles with a valid language code. So perhaps you can peek at the VLC code? Unless a teletext decoder is required for that part (I have no clue).

@Tetsou55
Thanks. I'll try to remember that for future use.

[STaRGaZeR]

so bear with me while i try different approaches. =)

Ofc :)

but ffdshow subtitle renderer doesnt even connect to the DVB subtitles, wonder if MPC does..

ffdshow doesn't support DVB subs, MPC does.

[naomatrix]

Thank you for the splitter , great job.

Stuffed in a Pot 1.5.23507Ru place MKV / WebM, AVI, MP4/MOV, TS/M2TS/MPG, FLV, drove on the test files at 1080p (720p) BDrip everything seems Ok
Of course there is for 0.4 versions are still drawbacks - no graphical interface, yet buggy to switch audio and subtitle roads, more slowly shifts.
But there is a big plus, correctly sees and connects the sound of the road (TrueHD, DTS MA), as well, and I'm very pleased so far the world's only splitter that correctly identifies the audio format AAC + + HEv2 SBR PS 2ch (5.1ch). Believe me I've tried a lot of splitters and decoders AAC (6 pieces) all spoke HE SBR 2ch PS (parametric stereo) as mono, only LAVFSplitter correctly identifies.

Good luck

[Ger]

I did some digging, and don't take my word for it (my understanding is limited), but there may be something of interest here:

Regarding the hearing impaired flags in DVB-subs: Page 38 and 73 (http://www.etsi.org/deliver/etsi_en/300400_300499/300468/01.11.01_60/en_300468v011101p.pdf).
Teletext subs vs non-subs: Page 8 (http://www.etsi.org/deliver/etsi_en/300400_300499/300472/01.03.01_60/en_300472v010301p.pdf).

Both found here (http://www.dvb.org/technology/standards/).

If that doesn't help, I guess VLC git or Enigma2 git.

[nevcairiel]

I did some research, and it seems that i can even get LATM AAC to work. It was only disabled in libavformat because libavcodec does not support it, but for example libfaad does.
This will have to wait until i setup my own ffmpeg repository with some custom patches though, so not 0.5 i'm afraid.
I hope to get 0.5 out today with the fixes for TS durations, DVB subs, audio/subtitle stream switching, the "No Subtitles" option and possibly some other small things, but for now i'm still stuck at work, so don't hold your breath, it'll be a few hours.

Speaking about AAC, does anyone know if the populare AAC decoders (ffdshow, mpc-hc internal, CoreAAC, ...) understand the HEAACWAVEFORMAT structure, or if they require everything being packed up in a WAVEFORMATEX?
Edit: I just noticed that CoreAAC does not have LATM support yet, so i guess the monogram decoder will have to do. :)

[tetsuo55]

Yeah a custom ffmpeg "fork" sounds like a good idea, that way work can be done on the various patches we have/intend to create and clean them up if/before they are committed upstream

Wow, didn't expect that. Sounds promising. If we get a free DS splitter working for LATM, the chances of seeing LATM support added to ffdshow/MPC-HC decoders should improve as well, since libfaad is used for AAC both places already. But Monogram-AAC should be fine in the meantime.

Take your time. Some of us have waited years for a project like this, so we can certainly wait a little longer. Thanks again. :)

Sound like version 0.5 will be a great step ! I will wait for it before continuing my test with others samples. :)

LAVFSplitter 0.5
- Fixed duration of MPEG-TS files
- Added support for DVB subtitles
- Fixed switching of Audio and Subtitle Streams
- Added a "No Subtitles" Stream

Download: 32-bit (http://files.1f0.de/lavf/LAVFSplitter-0.5.zip) & 64-bit (http://files.1f0.de/lavf/LAVFSplitter-0.5-x64.zip)

I hope the stream switching works properly now. The current approach works as follows: For Audio Streams, it deletes the current audio decoder, and lets the graph choose a new one, this ensures that we always get the right codec. For Subtitles (and Video), i just disconnect the filter, and let the graph reconnect itself. This seems to work fine so far. Feedback is appreciated. =)

On the DVB Subs: It can't detect the difference between normal and hearing impaired yet, thats still on my list of things to do.

[liquidskin76]

Hey nevcairiel,

I haven't had chance to test 0.5 yet, but was curious if the stuttering when begining a vid has been fixed? I was still seeing it with 0.4.

Thanks

[nevcairiel]

Did you see it in the changelog? :d

I'll try to get that one on the weekend when i have more time to try some things.

The audio part does work very well but I cannot get the DVB subtitles to work ... It may be me doing something wrong, can someone tell me what I should do exactly to ensure MPC-HC can display subtitles without problems ?

[nevcairiel]

Use one of the supported renderes, on XP that would be VMR9 (renderless), on Vista/7 EVR-CP, it should just magically work then. Additionally during playback check the "Play -> Subtitles" menu if Enabled is ticked
Oh, and the splitter currently defaults to the "No Subtitles" stream, so you need to turn them on, but i think you figured that out.

Some quick v0.5 first impressions:
- MPC-HC crashes when seeking in TS. Not always, but often. Mostly tested with the "Henry IV" sample and is easily reproduced with that sample on my system, but also seen with other samples.
- When enabling DVB-subs in "John Adams" sample, the video freezes. Don't know if this is related to the missing audio support.
- When enabling DVB-subs in "Henry IV" sample, quick video audio freeze, but then resumes and works, so I guess that is expected with the graph reconnecting on change. Would be ideal if it could be enabled seamlessly, but it's probably no big deal if it stays like this.
- TS duration is better (in most cases), but still not OK. HD sample duration is very wrong. I have another HD, sample here which doesn't play at all now, but the previously uploaded "Gossip Girl" HD sample (which is really just over a minute long and was reported as over an hour long in v0.3) is now reported as over 7 hours long in v0.5, but it plays. I don't think there is any point in uploading the other HD sample that doesn't play at all anymore in case it's duration related, and you can see the duration problem in the "Gossip Girl" sample as well.

[nevcairiel]

- MPC-HC crashes when seeking in TS. Not always, but often. Mostly tested with the "Henry IV" sample and is easily reproduced with that sample on my system, but also seen with other samples.
I can't really reproduce this. Do you use the MPC-HC internal video/audio decoder, or others?
Edit: I just noticed that for some reason the internal mpeg2 decoder doesnt even connect to the stream in the Henry IV sample. Another thing to check out.


- When enabling DVB-subs in "John Adams" sample, the video freezes. Don't know if this is related to the missing audio support.

A short freeze is to be expected, as the graph is stopped to change the stream connections. Here it resumes after that. What do you mean with freeze exactly, does it stay stopped?
Again, what filters?

[Ger]

Yes, it stays stopped. I'm using EVR Sync, with Sync Video To Display.

I can't confirm this two bugs (I only tried my own samples) but ...

... I can confirm those. When switching audio or subtitle there is a little freeze which doesn't seem to exist with VLC and for TS with H264 video track, duration is totally wrong (cf sample : http://www.mediafire.com/?g2xjd4rwa2n). By the way, with this sample I can't get the E-AC3 audio to play (whereas it works with internal splitter), is this expected ?

[Ger]

With the "John Adams" sample when I first open it, I get a warning about missing audio codec. I click that away and it starts playing (with no audio obviously and with wrong AR). If I then press stop, and play again, it remains frozen. Does that happen with you? This also happens to me with the internal splitter, but not with Haali (stop and play works with Haali).

I'm using Microsoft Win7 decoder (preferred in MPC-HC).

Changing from EVR Sync to EVR Custom didn't seem to change anything.

Edit: OK, the freeze on enabling subs and after stop/play depends on the H264 decoder also, as well as the splitter. With ArcSoft decoder that freeze doesn't happen, but video plays at seemingly double speed. Perhaps due to the AnnexB stuff in the first post?

[nevcairiel]

If I then press stop, and play again, it remains frozen. Does that happen with you?
No, but i also use ffdshow instead of MS, going to test that.
Actually, the AR is correct with ffdshow as well.

The small freeze on stream switches cannot be avoided, its here to stay. Comparing to VLC on this matter is pointless, as the freeze is a result of Direct Show interaction

Edit:
I see the freeze issue with the MS thing as well.

I has quite sure of your answer, it is ok then. :)

[Ger]

I just noticed that for some reason the internal mpeg2 decoder doesnt even connect to the stream in the Henry IV sample. Another thing to check out.


Actually, for MPEG-2 video I can't get it to connect to anything except ffdshow now. :confused: If I block ffdshow it refuses all other MPEG-2 decoders on my system.

All my crashes on skipping are in MPEG-2 files, so I guess they must all have been with ffdshow as the video decoder then.

Tried both ffdshow and internal for MPEG audio, and crash with both.

H264 still connects to whatever I set to preferred.

If I missed any questions, ask again. I hope I've answered everything.

Edit: To reproduce the crash, try clicking on different parts of the seek bar in quick succession with MPEG-2 TS samples with ffdshow for video. CTRL-LEFT and CTRL-RIGHT (I think those are the original shortcuts in MPC-HC for jumping a few seconds back/forward) also causes the crash, especially when done in quick succession. I've changed mine to just left/right arrow like in other players so I'm not 100 % sure what the default shortcut is anymore.

[STaRGaZeR]

No subtitles option, subtitle and audio switching working like a charm, good work.

Minor things I noticed:

- Seeking seems a bit slower than Haali/Gabest, specially with high bitrate Blu-ray content where there's a lot to decode if you don't seek to an I-frame. Same with stream switching, a bit slower. Maybe Haali doesn't reconstruct the entire graph?
- I'd put the no subtitles option always at the bottom of the subtitle streams list, instead of at the top.
- There's nothing in MPC's Navigate -> Audio Language -> ??. Same with subtitles. ffdshow detects the stuff though (it uses IAMStreamSelect).

[Kurtnoise]

By the way, with this sample I can't get the E-AC3 audio to play (whereas it works with internal splitter), is this expected ?

should be fine with this (http://pastebin.ca/1919682)...;)

I don't know much but it would make sens. I think you have made a little typo, correct patch is probably : http://pastebin.ca/1919690 ... :)

[naomatrix]

OK, now soundtracks and subtitles switches quickly, but the screen at this point flashes black.
And there are new challenges - in PotPlayer(madVR) LAVFSplitter for .avi files does not connect to XVID decoder (also DivX,3viX) only built-in codecs, and on .TS interlaced 1080i MPEG2 (4:2:2) did not see Elecard Mpeg2 HD codec (also DScaler Mpeg2 Video Decoder).
The same problem in the MPC-HC(EVR), only sees the built-in decoders, possibly errors in the players or splitter ?
Another small question, is it possible to make an icon in the tray, as an indicator of spliter's work.
And yet another side issue, there is a problem with Cyrillic fonts in splitter's message.

Thanks.

[nevcairiel]

OK, now soundtracks and subtitles switches quickly, but the screen at this point flashes black.

Like i said before, this is a side effect of the graph rebuild and cannot be avoided. I tested with Haali, and it does the same, i also get a short interruption of playback. I realize that the switch seems a bit slower then on Haali, but sadly there are no other open-source splitters that do this, so i'm building this from scratch, and seeing how this goes.

I can do one change, and on audio switch try to connect to the old filter. If it accepts the connection, just go with that one. This does however have one drawback. If you, for example, use ffdshow, it can handle most, if not all, audio formats, so once its in use, it would not switch to another decoder, even if it has a higher merit. Is this a real problem? To fix it, you would have to turn the formats you don't want ffdshow to handle off in its configuration, but not every filter supports this kind of configuration.
For me it would be fine, as i use ffdshow for most formats, and ffdshow supports turning off the formats i don't want, but i realize not everyone uses a simple setup like this.
I might make this behaviour configurable once i have a property page.

I'll look into the issue with mpeg2 decoder connections, its probably a simple thing thats wrong in the format header.

Btw. MPEG-TS is such a screwed up format, no wonder there is no good reference splitter for it.

[tetsuo55]

I can do one change, and on audio switch try to connect to the old filter. If it accepts the connection, just go with that one. That actually sounds like a good idea for all the streams? do you think that is possible?

Also, the slower seeking might be partially caused by time based seeking vs keyframe based, maybe that should be ruled out first?

[nevcairiel]

That actually sounds like a good idea for all the streams? do you think that is possible?

Video and Subtitles already do this, as replacing the video decoder causes some issues, and the subtitle decoder is usually linked to the video decoder/renderer in some way.

Also, the slower seeking might be partially caused by time based seeking vs keyframe based, maybe that should be ruled out first?
MPEG-TS doesn't offer an easy way to get the keyframes like MKV does, this will need some custom magic to figure out where the GOP borders are.

[tetsuo55]

God MPEG-TS sucks :(

[naomatrix]

I tested the LAVFSplitter on this set of files http://thepiratebay.org/torrent/5155837/HDTV_test_files_%28v1.7%29 in PotPlayer/LAVF/MadVr/(XP SP3;Athlon64X25600+/Nvidia9800GT/LCD1400x900)
Overall not bad but there are exceptions:
in file 00019.m2ts (Interlace) splitter can not connect the LPCM audio track to any decoder, indicates error, while Haali quietly connects ffdshow audio decoder;
in VC-1_Sub.mkv does not connect to WMVideoDecoderDMO for "WVC1" FOURCC, like any other except the Pot's built-in(FFmpeg);

That's all, thank you

[kieranrk]

MPEG-TS doesn't offer an easy way to get the keyframes like MKV does, this will need some custom magic to figure out where the GOP borders are.

MPEG-TS has a keyframe flag in the header.

[nevcairiel]

Okay, a little status update on MPEG-TS support.

The remaining duration problems are bugs in libavformat. You can easily verify this yourself when running the files through ffplay or ffprobe (i can provide binaries later). TS isn't the best supported format in avformat, sorry.
I have some plans in mind that might improve this situation, but i don't want to go into specifics just yet. It probably will be some time before you hear of this again, so much stuff to do first!

I'm working on a fix for the MPEG-2 headers to properly connect to other filters, and i'll try to fix VC-1 to work with the MS DMO decoder. About the MPEG2 crash .. i'll try to reproduce this first.

Also, i haven't forgotten about all the non-TS bugs, and i'm looking at them too.

[hoborg]

I updated my post (http://forum.doom9.org/showthread.php?p=1426670#post1426670) - tested on 0.5 now.

[Virtual_ManPL]

Finally someone make splitter from scratch to replace buggy Haali and not developed Gabest splitter :devil:

Feature request:
1. Tray icon to easily manage streams and chapters (like in Haali)
2. Support for indexless, metadateless or other broken or unfinished files
3. Ogg splitter

Okay, a little status update on MPEG-TS support.

The remaining duration problems are bugs in libavformat. You can easily verify this yourself when running the files through ffplay or ffprobe (i can provide binaries later). TS isn't the best supported format in avformat, sorry.
I have some plans in mind that might improve this situation, but i don't want to go into specifics just yet. It probably will be some time before you hear of this again, so much stuff to do first!

I'm working on a fix for the MPEG-2 headers to properly connect to other filters, and i'll try to fix VC-1 to work with the MS DMO decoder. About the MPEG2 crash .. i'll try to reproduce this first.

Also, i haven't forgotten about all the non-TS bugs, and i'm looking at them too.

Ok, thanks a lot for your work.

As there will be probably a lot of bug reports that you won't have time to look at rapidly, don't you think it could be great to have some sort of bug tracker to keep trace of them better than a thread where it will gradually become very difficult to find them ?

vlc demuxer seems to be a lot better in that regard.

vlc demuxer seems to be a lot better in that regard.

Well, VLC demuxer is quite strange too. It does not seem to correctly detect the duration since it displays 00:00 but seeking works, I don't understand how it can be possible so maybe it is just a display problem ...

I was storing important links in some text file so far. :D but i've been thinking about a proper project page before, and i'll just set it up on googlecode or so.

The readme mentions that it is needed to uninstall Haali. That is actually not needed at all. Simply use this registry key to enable use of LAVFSplitter:
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Media Type\Extensions\.mkv]
"Source Filter"="{B98D13E7-55DB-4385-A33D-09FD1BA26338}"

May I suggest to enable runtime CPU detect and not force compilation for a specific CPU type. The filter currently does not work on older CPUs.

Can you give a list of which entries in the following key correspond to which file formats? That will allow the testers here to tweak the filter registration until a configuration dialog is implemented.
HKEY_CLASSES_ROOT\Media Type\{e436eb83-524f-11ce-9f53-0020af0ba770}\{9C53931C-7D5A-4A75-B26F-4E51654DB2C0}

An INI file could be useful to specify for which formats the filter should register itself during installation/regsvr32.

Figured out the list myself:
HKEY_CLASSES_ROOT\Media Type\{e436eb83-524f-11ce-9f53-0020af0ba770}\{9C53931C-7D5A-4A75-B26F-4E51654DB2C0}

Does anybody know why the splitter cannot be registered with Inno Setup? Using a simple script like this (http://xhmikosr.1f0.de/patches/lavfsplitter/LAVFSplitter.iss) fails with a RegSvr32 failed with exit code 0x3 message.
