Hi Mike

I got a message from the mail daemon that the message could not be delivered to mike at haali.net. So resending.

Could you set the following registry key during your haali splitter setup?
This will cause .mkv files to be rendered using DShow in WMP and not using format SDK or plugins.


On x86 machine

HKEY_LOCAL_MACHINE\Software\Microsoft\Multimedia\WMPlayer\Extensions\.mkv
 Runtime = 7
 Permissions = 15 (0xf)

On x64 machines
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Multimedia\WMPlayer\Extensions\.mkv
Runtime = 7
 Permissions = 15 (0xf)

Adding Shyam and Naveen,
Using undocumented features is not recommended.
Using 15 (0xf) should be sufficient for preventing WMP from popping up the dialog box to confirm playback.
I verified that on both x86 and x64 machines.
Also note that since haali is x86 only it should use WOW64 node on 64 bit machines.

On x86 machine

HKEY_LOCAL_MACHINE\Software\Microsoft\Multimedia\WMPlayer\Extensions\.mkv
 Runtime = 7
 Permissions = 15 (0xf)

On x64 machines
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Multimedia\WMPlayer\Extensions\.mkv
Runtime = 7
 Permissions = 15 (0xf)



Thanks

Better yet, the Permissions should be 0x2f (47).
Apparently the 0x20 bit, while not documented, tells WMP not to ask this 
annoying question like "I don't know this extension. Do you want to open 
it anyway?"

I myself experienced the similar problem more than once: after 
installing or uninstalling Haali Splitter, MKV which played perfectly by 
MPC before, doesn't play anymore because WMP gets in the way, and silly, 
it gets in the way like "I am the app who opens .mkv" but it cannot open 
it, with the unhelpful error code C00D0FEA.

Although, since the problem is easy to fix, I didn't care very much.

Anyway WMP11 cannot open .mkv even when mplayer2 or graphedit can, 
because of the above registry settings. So it may be a good idea for the 
installer to make sure the registry values are set correctly, if it 
wants WMP to play mkv. But actually, everyone will be happy if it does 
NOT change the association when .mkv is associated to something else 
already, and if it does change the association, it'd be nice to 
remembers the previous association and restores it when uninstalled.
I bet Haali got this requests many times already anyway, because some 
people get angry when an installer changes the association and/or the 
icons even without asking.

Subject: [Matroska-devel] 'H264' from 'AVC1' in .mkv
Message-ID: <56B3B8C551E3A946917C6E424864078D3634BD6FED@NA-EXMSG-C115.redmond.corp.microsoft.com>

Hi.  I'm a Software Engineer at Microsoft working on Windows Media Center.  I got your contact information from a colleague of mine who works in our codec group.  Please redirect my inquiry if you are not the best person to contact.

We are running into an issue where Media Center Extenders are unable to play h264 content in .mkv files.  The problem is that our device-side decoders support only start-code-delimited 'H264', not length-delimited 'AVC1'.  In addition, these decoders require SPS and PPS information in-band (as in H.264 Annex B specification).

We would like to be able to play this file format.  Does your organization have any plans to expose an 'H264' media type from your Haali splitter?  As I understand it, this would be a fairly straight-forward conversion by overwriting NALU lengths with start codes and inserting the SPS and PPS directly into the stream.

If not, is this something you could consider as future work?


Thanks,

Will Stoltzman

Adding Mike and Mathias,

We discussed this before, but didn't pursue it further since support for AVC1 media type was added to Win7 inbox H.264 decoder itself.
However, at that point we didn't think about the H.264 decoders on devices like Xbox, Media Center Extenders which cannot be easily upgraded.
I am copying the original dicussion for reference.

Hi Haali,

We have added support for 'AVC1' format in our windows7 build (post beta). Vista didn't have h.264 decoder inbox, so there is no need to add any media type to Haali Splitter.
Also I have confirmed that post Vista, the VC1 decoder DMO accepts VIH2 headers. 
In XP, VC1 DMO did not accept VIH2 and WM ASF Reader exposed only VIH2. The DMO wrapper emulated VIH2 if the source filter was WM ASF Reader and the DMO did not support VIH2.
Since VC1 DMO accepts VIH2 from Vista, there should not be any problem connecting with haali splitter.

I've documented most of the formats supported by the splitter at http://haali.net/mkv/codecs.pdf along with DShow media types, there is also the description of AVC1.

I'd need to know what media subtype and format you are using for Annex.B streams in DShow, because
I'm not aware of any standard type that can be used for that, with most splitters/codecs using their
own fourcc and format. The closest is AVC1 with Format_VideoInfo(2), but there are still problems with
timestamps, as some splitters use DTS (e.g. when ppl store h.264 in avi), and some use PTS.

In addition, these decoders require SPS and PPS information in-band (as in H.264 Annex B specification).? 

We would like to be able to play this file format.? Does your organization have any plans to expose an 'H264' media type from your Haali splitter?? As I understand it, this would be a fairly straight-forward conversion by overwriting NALU lengths with start codes and inserting the SPS and PPS directly into the stream.? 

If not, is this something you could consider as future work?


Thanks,

Message-ID: <4834942.1014701237390511381.JavaMail.coremail@bj126app66.126.com>

 
Hi, 
I am a beginner of video encoding/decoding and Haali Media Splitter. Recently, I am engaged in a project which converts m2ts (AVCHD video format of SONY) file to mpeg2 video. This converter is developed with VS 2005 and DirectShow. 
Haali Media Splitter can be used as the DirectShow filter to decode the m2ts format file, and I want to know how to encode the video and audio stream after decoding. Can anyone recommend me some mpeg2 encoder filters to do this task? Any suggestions will be greatly appreciated!

Regards,
Wisent

Subject: [Matroska-devel] HD Subtitles Format status
Message-ID: <gprbpr$tt$1@ger.gmane.org>

Hi,

I would like to have some feedback regarding HD subtitles format (more 
exactly subs from HD-DVD & BD discs).

S, is there a plan to add this to the current tools like mkvtoolnix or 
dsmux ?

I ask this because there is a tool[1] which is able to mux them directly 
to a matroska file but unfortunately, I'm not able to play those files 
despite the fact the Haali Splitter finds them into the stream 
(S_HDMV/PGS as CodecID).

Thanks for your response.

	Haali Media Splitter
Message-ID: <20090321175532.33828.qmail@web2508.mail.tnz.yahoo.co.jp>

Hello,

I have noticed that I can't play some of my MP4 files correctly with Haali Media Splitter.
When I open the files they seems to be okay. However, once I click the stop button, the player does not begin to play even if I click the play button. After seeking the files, the player begins to play again.
When I use the internal MP4 splitter of Media Player Classic HomeCinema, the problem doesn't occur but the delay doesn't take effect.
I have found what is different between playable files and unplayable files. Files with AAC audio of which delay is larger than 43ms are unplayable.

MP4Box -add audio.aac:delay=42 -new audio.mp4  ...OK
MP4Box -add audio.aac:delay=43 -new audio.mp4  ...OK
MP4Box -add audio.aac:delay=44 -new audio.mp4  ...NG
MP4Box -add audio.aac:delay=45 -new audio.mp4  ...NG

and so on...
Please investigate this bug.


Rigards,
Hiroki

Subject: [Matroska-devel] Output of sup (Blue-ray) subtitles from Haali
	Media Splitter?
Message-ID: <loom.20090329T123358-784@post.gmane.org>

I'd like to write a DirectShow filter that renders sup format subtitles and that
I can use with my own media player (http://www.ostrogothia.com/video). Just as a
test, I compiled the DirectShow example "dump" filter which accepts any type of
input and writes it on a file. I connected it to the subtitle output pin of the
media splitter and played an m2ts file. The Haali stream selection menu reports
a number of subtitle tracks. None of them gets rendered to a file though through
the dump filter (the file remains empty).

I might have done something wrong of course but just to check:

Does the Haali Media Splitter actually output sup format subtitles on its
subtitle pin?

And just in case: Is already a sub rendering filter that takes that sup output
(if it exists) and generates bitmapped frames that can be fed into e.g. the VMR9
renderer?

Thanks a lot for your input (and output :-))!

Subject: [Matroska-devel] Support for TrueHD audio
Message-ID: <200903291823.45343.moritz@bunkus.org>

Hey,

I've just added support for TrueHD audio in mkvmerge, one of the more
often requested features.

Now I need support for it in Haali's splitter :)

The format is really simple: CodecID is "A_TRUEHD", no CodecPrivate,
just deliver the content as-is.

A small sample EVOB file which can be used for testing is available
here:

http://www.bunkus.org/misc/AVC.TrueHD.DDP.2xDD.evo

Here's a mkvtoolnix build with support for TrueHD:

http://www.bunkus.org/videotools/mkvtoolnix/win32/pre/mkvtoolnix-unicode-2.6.0-build20090329-99-setup.exe

A couple of notes about storage. TrueHD streams consist of two different
frame types: one with a full header and a sync word, and then several
others without the full headers. Decoding can only start at the sync
frames. Those frames all contain very few samples (as few as 40 samples)
and are very, very short (e.g. only 30 bytes). Therefore mkvmerge does
NOT put each frame into a Matroska block. Instead each Matroska block
contains one sync frame and all following non-sync frames. This is about
110 ms of data. mkvmerge disables lacing for TrueHD audio tracks so that
there won't be ~ 1 second of data with a single timecode.

I don't see any advantage in putting the non-sync frames into separate
Matroska blocks; this will only waste tons of space and not gain
anything.

Another thing is that BlueRay discs may contain AC3 frames between the
TrueHD frames so that decoders capable of decoding AC3 but which don't
know TrueHD can still decode this stream. These AC3 are dropped by
mkvtoolnix. HD DVD doesn't contain such AC3. BlueRay discs should always
contain the same audio track als Dolby Digital Plus, AC3 or something
like that in addition to the TrueHD version, so nothing is lost by
discarding the embedded AC3 frames. Another argument for discarding them
is that they have to be discarded prior to sending the stream over a
HDMI interface anyway.

Regards,
Mosu

Hmm, at least ffmpeg has problems with so many frames in a single
packet. I'll implement 1:1 storage and see if that's better.

http://www.bunkus.org/videotools/mkvtoolnix/win32/pre/mkvtoolnix-unicode-2.6.0-build20090329-100-setup.exe

This build can do both. It defaults to putting each frame into its own
Matroska block. This works nicely with ffmpeg (on Linux).

mkvmerge knows a new option, "--engage merge_truehd_frames", which turns
on the prior behaviour of merging a sync frame with all following
non-sync frames in a single Matroska block.

Sorry guys, I goofed. The media splitter does seem to output something. It was
just that the subtitles didn't get going until several minutes into the
m2ts file. There was a long intro about the movie company or something that
didn't seem to be subtitled although there was a spoken audio track.

Any hints as to how to render the sup format are welcome. I've seen some info
over at doom9's that I'll start with. Something about run-length coded bitmaps
(how ugly can it get?).

Still interested in knowing if such a renderer filter already exists.

Thanks!

Hey,

http://www.bunkus.org/videotools/mkvtoolnix/win32/pre/mkvtoolnix-unicode-2.6.0-build20090330-102-setup.exe

another build, this time with support for MLP. MLP is almost identical
to TrueHD. Therefore the storage in Matroska is identical but for the
CodecID which is A_MLP. CodecPrivate is empty.

ffmpeg deocdes both MLP and TrueHD with the same code, so it should be
trivial to add support for MLP on top of support for TrueHD.

I've tried to do a straight conversion of this file to mkv using latest
git tree of mkvtoolinx. It seems to work fine except for one thing.
It seems it confuse sampling freq and channels count. Here is what
mkvinfo show for the truehd track:

  + Audio track
   + Sampling frequency: 6.000000
   + Channels: 48000

This only happens for truehd (and maybe mlp, I haven't tried).

Dang... Thanks for noticing. I swapped parameters in a function call in
the MPEG PS handling code. Therefore it only happened with EVOs, and
yes, both for TrueHD and MLP. Has been fixed; you can pull.

I've also attached a patch for ffmpeg which adds the CodecIDs to the
Matroska demuxer; this seems to be all to get it working.
