Apparently the work we did to use Vorbis without Ogg is not worth taking 
in consideration ?
Or is matroska simply responsible for the Oggless concern ?

Hello all,

The Xiph.Org Foundation would like to invite the Matroska Developer
Team to join the discussion regarding the Oggless Proposal, how to
improve, what to change, etc.

The Oggless Proposal will be Xiph's official position on how to use
our formats (Vorbis, Speex, FLAC, Theora, etc.) outside the Ogg
container.  There has been interest in this, as well as incompatible
proposals and implementations on the wild, which are hurting any
possible interoperability.

As developers of a container format--and a rival one at that--I am
sure you would like to join the discussion.  Thus, why we are
invinting you, as well as Media Player developers like the
MPlayer and the VLC teams, as well as the ffmpeg
team to create one standard way of doing it.

If you would like to join the effort, be sure to read the current
proposal [1] and either edit it directly, or discuss changes on the
ogg-dev [2] mailing list.

Best regards,
Ivo Emanuel Gon?alves,
Xiph.Org Foundation

Message-ID: <loom.20070605T085253-641@post.gmane.org>

Hi Haali,

I started using your Video Renderer in ZoomPlayer instead of VMR9. Works and
looks very fine. However, there is one bug. With some files, mostly dvr-ms files
recorded with Mediaportal the automatic aspect ratio (derived) in ZP does not
work anymore. Instead it is always 16:9 and has to be set to 4:3 manually. With
VMR9 everything works fine.

If you need a sample file, please let me know.

Thanks,

Dear Developers,

     This is Amad from V One Multimedia Pte Ltd. V One Multimedia is Head
Quartered in Singapore. We actually design and manufacture different Video
Encoding/Editing & Consumer Electronic products covering the most rapidly
emerging technologies including solutions encompassing HDV, H.264, WMVHD,
HDTV, DVBT, Digital Signage and Connected Homes.

 

So far our products have acclaimed prestigious awards from different
magazines. Our product SnaZio* Net DVD Cinema HD has been a success in High
Definition Networked Player market. This product was based on Sigma Designs
EM8620. As the decoding technology is being shifted to H.264, we are
planning to integrate Matroska support in our next generation of product
which is based on Sigma Designs EM8623 with H.264 decoding capability. I
would like to explore the possibility of working together on this platform
to integrate the support for MKV format on our new players.

 

This will definitely help both of us in providing a good product in market.
I understand from your news that you have been providing support to Ziova
for Z500 and I would appreciate if same level of support can be given to V
One Multimedia for Matroska integration. 

 

I hope we can collaborate further on this project. Should you require more

Hi !

This does not only happen with evo files but other files encoded with H264 too.
Also it happens with more decoders, not just ffdshow. I tried the Mainconcept
H264 decoder for instance.

It works fine with the CoreAVC decoder but I?d rather use other decoders because
of the quality issues with CoreAVC.

Could you fix this please ?

Thanks a lot !

Dear Mike,

   Would that be possible to have some sort of organized documentation
regarding your API usage and your playback libraries to be able to support
MKV on our platform? 

At this moment, I am not very sure how to extract the H.264 files from the
MKV container. Definitely there could be some way but so far I have not seen
any Sigma based player to support this. I am not experienced about MKV specs
but I guess MKV is not more CPU intensive than any other container format
available. Perhaps you can send us some detailed information. 

 

Currently we are working on EM8623 processor and using Marua SDK which comes
with Mono player.

Amad

Hi again,

sorry, seems like the problem I posted has different reasons and does not fit in
this thread. Instead it seems like the Haali Video Renderer takes much more CPU
cycles compared to VMR9 so if ffdshow is used as a renderer for HDTV, the video
will lag behind the audio.

If coreavc is used everything is fine again ... since coreavc is less demanding
on the CPU that makes sense. 

Currently I cannot play back 1080p HDTV files on my computer with Haali Video
renderer even though my CPU is a Intel Core 2 Duo 6600. I even tried
overclocking the CPU to 3 Ghz, still not enough :-)

Thanks :-)

I think a long time ago I started a docbook file (or maybe it was for 
MCF) to describe the format. But finally went to HTML as it was faster 
to update.

But docbook is a good format as it can be "compiled" into many other 
format. Also you might have to learn the syntax (dunno if there are 
fancy editors).

The preferred output would be something that look like an ISO Spec in 
PDF format (which field describe in perspective of the format). But you 
can write it in RTF and print/export it to PDF afterwards.

Docbook is in XML so it could be good to use that.

It's also used in CorePlayer/TCPMP so works in embedded environments 
too. Although I don't know the specifics of the Sigma chip constraints 
(for ex if special buffer have to be used for decoding or how the sync 
is kept between formats).

functionality of these test apps as I am very new to MKV.

   Can any one help me to locate a simple parser app (which uses libebml 
and libmatroska), which can be used to parser MKV file (probably be able 
to dump the audio video streams to different files). It will also be 
helpful, if you can point me to some link where I can download few MKV 
files.

Hello Haali,

I've found 2 special TS-Files. Your media splitter can't split these files. I
hope, these files are interesting for you.


The first file is a DVB-T-file from Norway. They are broadcasting H.264 / AAC.
This is the link to the original post by Griga:
http://forum.dvbtechnics.info/showpost.php?p=24450&postcount=3

This is a translation:
Audio is strange. Streamtype in the PMT ist 0x11, the package is TS -> PES ->
LOAS -> LATM -> AAC-HE.

Alternative link to Griga's sample (a short audio file):
http://akapuma.info/test/nrk_aac_he2.zip



The second file is a sample from jmittelst, posted in the german
doom9-gleitz-forum. Link to the post:
http://forum.gleitz.info/showpost.php?p=335401&postcount=2

A translation:
TS-Files, recorded with a Dbox via Udrec, contains no PMT/PAT. MPC and MPlayer
can play these TS-files. Haalis splitter can't play the files. These files
contains only normal MPEG2-video and audio.

In the spec it looks like only regular Blocks (or VirtualBlocks) go into BlockGroups and that SimpleBlocks and EncryptedBlocks sit at the same level as BlockGroup and therefore would never be found as multiples within a BlockGroup, is this correct?


In the various definitions for Block Structure there is this sentence: "It is used with different parts of a frame with different priorities.", what does this mean?  Doesn't a Block contain one or more frames?  Can you actually have one frame split up over multiple blocks?  If so, how could you tell (by timecode?) and why would you want to do this?



Thank-you,

Hi Kunal,

the codec ID is indicating that this video stream is a so-called 'Video 
for Windows' compatible video stream, and that it was most likely coming 
from an AVI file originally. You can not just give it a .m4v extension 
to be able to play it, you have to repack it into an AVI file for that. 
However, there is a free, open source tool called 'mkvextract' in Mosu's 
mkvtoolnix tools ( http://mkvtoolnix.matroska.org ), that will do 
exactly that for you already. Its a command line tool, but there is a 
GUI for Windows for it, called 'MkvextractGUI' . Google is your friend 
to find the latest binaries, because i am not sure if its still hosted 
on http://www.corecodec.org any longer  .... :-)

Message-ID: <loom.20070615T022314-138@post.gmane.org>

Hi,

The HTTP streaming support in the splitter works great, but I've found a small
problem in addresses that have a query in them.

I don't know if this is something that can be fixed in the splitter, but when
using an address such as "http://www.example.com/testfile.avi?query=value" it
fails to load. I can only guess that this is because the actual end of the
string doesn't contain a file extension that is recognised.

I can't tell if this is the application not loading the correct filter, or the
splitter not parsing the address correctly. Any ideas?

Subject: [Matroska-devel] Streaming MKV files via ASX scripts?
Message-ID: <939683.58074.qm@web27207.mail.ukl.yahoo.com>

I was experimenting with streaming MKV files via ASX scripts to Media Player 10 and VLC 0.8.6b and noticed the following:

1) A simple <entry> tag worked just fine and the file(s) would playback normally (including seeking and jumping to chapters once playing).

2) Using the <starttime value="1:00.0" /> tag would start one minute into the file in Media Player but that first minute would be "lost" and could not be jumped backwards into and the overall file length would be reported as one minute shorter.  On one computer I tried it on Media Player behaved strangely and would not play the video at first and generated a weird error about being low on memory (with a gig of free RAM) but would play after pressing the play button again, on another machine it was fine (but still "missing" the video from before starttime).  In VLC the tag was ignored and the file would play from the begining.

3) Using the <duration value="1:00.0" /> tag worked as expected and only played for one minute.

4) Both Media Player and VLC seemed to "ignore" the <startmarker number="2" name="Chapter 2" /> tag when I tried to apply it to Matroska chapters.


My questions now are:

1) Why does Media Player report the file length as being one minute shorter and "drop" that first minute when using the <starttime .../> tag with a MKV file?

2) Can some of the more advanced features like <startmarker .../> be made to work by making some changes in the splitter?  If so, is this something Haali or Gabest has time to implement?

3) Is VLC's behaviour on Windows dependent on filters or is it's ASX support coded internally? (note: I am not subscribed to any VLC mailing lists)

4) Is there some other mechanism to start a Matroska file playing at a particular chapter "automatically" instead of having to start at the begining of a file and manually select where to jump to?


Thank-you,
David

If I have an audio track that isn't of one of the Matroska known types should it get muxed in as A_MS/ACM?
I was under the impression that A_MS/ACM was the audio track equivalent of V_MS/VFW/FOURCC for video tracks but mkvmerge 2.0.2 refuses to mux an unknown audio type.
Thank-you for your input.

Subject: [Matroska-devel] Some special TS-Files
Message-ID: <466D87DE.5040908@akapuma.info>

Hello Haali,

I've found 2 special TS-Files. Your media splitter can't split these 
files. I hope, these files are interesting for you.


The first file is a DVB-T-file from Norway. They are broadcasting H.264 
/ AAC. This is the link to the original post by Griga:
http://forum.dvbtechnics.info/showpost.php?p=24450&postcount=3

This is a translation:
Audio is strange. Streamtype in the PMT ist 0x11, the package is TS -> 
PES -> LOAS -> LATM -> AAC-HE.

Alternative link to Griga's sample (a short audio file): 
http://akapuma.info/test/nrk_aac_he2.zip



The second file is a sample from jmittelst, posted in the german 
doom9-gleitz-forum. Link to the post: 
http://forum.gleitz.info/showpost.php?p=335401&postcount=2

A translation:
TS-Files, recorded with a Dbox via Udrec, contains no PMT/PAT. MPC and 
MPlayer can play these TS-files. Haalis splitter can't play the files. 
These files contains only normal MPEG2-video and audio.

Link to a sample: http://jmittelst.no-ip.com/Sample.rar

Best regards

Indeed it is. And yes, unknown types (for which no official CodecId
exists but for which a wave format type thingy exists, don't know the
name at the moment) can get muxes as A_MS/ACM.

True as well. This is a long-standing feature request for mkvmerge but
has never been implemented. And probably never will.

Yes, LOAS is not supported, but I'll add support for it at some future
date (when I get the documentation).

Streams without PAT/PMT are not supported, and I don't plan to add
support for them.

It could be both. I suspect DS has trouble selecting the source filter
by file extension in this case, but
this needs more testing to make sure.

Must be some weird WMP logic. Does MPC exhibit the same behaviour?

I think WMP does not support reading chapters via IAMExtendedSeeking,
and uses some private interface when reading WM files.

No, VLC uses internal codecs.

I thought about using some small 'redirection' files like QT does, but
didn't implement anything.

MPC doesn't play my test ASX file at all, it just shows "File not found" in the status at the bottom.
I think the time "cropping" in WMP10 & 11 may be the default behaviour because it does it with wmv files too, I was told that it didn't "crop" wmv files but I decided to test it for myself and apparently it does the same thing with wmv as mkv.  I also tried updating to WMP11 and it has the same behaviour.  So I think I was just given incorrect info about wmv files in asx and this is just how it works for any format.

Message-ID: <000001c7b301$b93891e0$6401a8c0@jeremyfixe>

Hi, 
I'm desesperately trying to play vorbis audio embedded in mkv. 

I develop my own mkv parser, 
it works with all kind of audio, but not with vorbis, 

Here is the code in my PushPin::GetMediaType method 

FOURCCMap fcc_subtypevorbis(0xcddca2d5); 
FOURCCMap fcc_vorbisformat(0x6bddfa7e); 
FOURCCMap fcc_subtypevorbis2(0x8d2fd10b); 
FOURCCMap fcc_vorbisformat2(0xb36e107f); 
m_mt.SetType(&MEDIATYPE_Audio); 

VORBISFORMAT2* pvf2 =
(VORBISFORMAT2*)m_mt.AllocFormatBuffer(sizeof(VORBISFORMAT2) +
tinf->CodecPrivateSize - 3); 
 memcpy((BYTE *)pvf2+sizeof(VORBISFORMAT2),reinterpret_cast<BYTE*>(tinf-
>CodecPrivate)+3, tinf->CodecPrivateSize-3); 
 m_mt.SetSubtype((GUID*)&fcc_subtypevorbis2); 
 m_mt.SetFormatType((GUID*)&fcc_vorbisformat2); 
BYTE *codecPrivate = reinterpret_cast<BYTE*>(tinf->CodecPrivate); 


                                                        unsigned long
lastHeaderSize = tinf->CodecPrivateSize-1; 
                                                        unsigned char
nbHeaders = *((unsigned char *)codecPrivate); 
                                                        codecPrivate++; 
                                                        // 3 headers for
vorbis 

                                                        while(nbHeaders) 
                                                        { 
                                                                unsigned
long currentHeaderSize = 0; 
                                                                do{ 
 
currentHeaderSize += *(unsigned char *)codecPrivate; 
 
lastHeaderSize--; 
                                                                }
while((*codecPrivate++) == 0xFF); 
 
lastHeaderSize -= currentHeaderSize; 
 
pvf2->HeaderSize[2-nbHeaders] = currentHeaderSize; 
                                                                nbHeaders--;

                                                        } 

 
pvf2->HeaderSize[2-nbHeaders] = lastHeaderSize; 

                                                        pvf2->Channels =
(WORD)tinf->AV.Audio.Channels; 
                                                        pvf2->SamplesPerSec
= (DWORD)tinf->AV.Audio.SamplingFreq; 
                                                        pvf2->BitsPerSample
= (WORD)tinf->AV.Audio.BitDepth; 
 
m_mt.SetSampleSize(1); 

*pMediaType = m_mt; 
return S_OK; 

The PushPin:CheckMediatype return always S_OK 

But at the graph construction, the audio majortype seems to have been 
lost 
the pin 1495cfc has major type 0x00000000... 

Any idea where to dig? 
Many thanks

Is it possible to build a DRM model similar to this system with Matroska?

United States Patent 20070136608: Off-line economies for digital media

http://www.freepatentsonline.com/20070136608.html

This is a patent that deserves to be infringed upon. MS can't be left
to monopolize a system this powerful.

I've got more information pertaining to how it was developed as well
as the business models and capabilities in my blog. There was a
slightly different version built around online capabilities 4 years
ago, built on the PlaysForSure model, but MS closed it down with
updates to windows media player and Vista.
