Subject: [Matroska-devel] I have a feature request about matroska tags
Message-ID: <CAL0=0H2=ZX8oMAaD19azhLxT7+SP455YMZx8S3FjuopwqOMQCQ@mail.gmail.com>

I don't know where else to ask this, so forgive me for asking this mailing list.

I want to add a tag entry that describes the name of the anime that a
song belongs to.

For example,
irony sung by ClariS is the opening song of Ore no Imouto ga Konna ni
Kawaii Wake ga Nai ( ???????????????? ).

Therefore, "irony" is a soundtrack of that anime.

What would be the proper tag entry for the name of that anime?

I couldn't find a proper one in both ID3v2 and matroska tag specification.

If there is no such thing, can you please consider making a new tag
entry for that kind of stuff?

Subject: [Matroska-devel] mkvalidator cluster/cues validation
Message-ID: <j1asrj$e00$1@dough.gmane.org>


mkvalidator complains about "first block for video track # not being a 
key-frame". Its only a warning but why complain about
something thats totally valid - in this case the CueBlockNumber points at 
the key-frame block. I could understand the warning if the
CueBlockNumber element had not been present or was pointing at the wrong 
block.

what seems to be missing from mkvalidator is a "cues key-validation" - if 
the first block is not a video key-frame and CueBlockNumber is not
present it should generate a warning. A warning because there does not seem 
to be any requirement that cues should only contain references
to key-frames. Also, mkvalidator seems to ignore the CueBlockNumber - 
writing a wrong block number does not generate any error.

please comment.

Thanks in advance

It is a warning because it's not optimal for seeking. A lot of data
will be read for nothing in this case, unless the Cluster is not
referenced in the Cues and if the Cues are not damaged.

I don't think there are much players that make use of the
CueBlockNumber element at all.

Hi Steve

Thanks for the reply.

Just to explain:

Could easily change my MKV muxer so the warnings disappears - aligning the 
clusters on video key-frame boundaries. However for highdef video files this 
is likely to cause an even more serious problem than
say slow seeking - namely that playing the file does not work properly. If 
the cluster size gets too big, players like VLC most likely ends up flushing 
its buffers periodically and playback suffers.

So the recommended way must be to keep the clusters at a reasonable size say 
512kb .. 1.5Mb and not necessarily align the clusters on video 
key-boundaries.

The matroska format seems to be prepared for this approach via the 
CueBlockNumber so the mkvalidator warning,  still makes little sense to 
me...

Using the CueBlockNumber a player could easily skip the specified number of 
blocks in order to find the "keyframe block" - and yes, its probably just as 
easy without the CueBlockNumber information :-)

Have you tried the large Cluster approach ? That's what mkclean does
with --remux regardless of the Cluster and it works fine. I don't
think there are any player that loads a whole Cluster in memory
(although that's one of the original goal).

Yes, I tried that and  ran into the problem of not being able to play all 
mkv files perfectly.

Investigated the matter and found that by reducing the cluster-size to a 
maximum of 512k-1Mb, the problem completely disappeared -  as far as I 
remember the critical cluster size was around 1.2-1.5MB/cluster.

Should be said that my own PC only has a AMD athlon 64X2 / 4200+ and a 
"slow" green-WD HD.

Regarding the VLC player , maybe my conclusion is wrong but using the 
"process explorer" and looking at the  I/O bytes history it seems that 
access to the file happens cluster-wise. With cluster size 1.5Mb , the I/O 
history repeatedly shifts betwen zero and 1.5Mb, with 1 Mb cluster size - 
between 0 and 1Mb. With cluster sizes limited by time (2 seconds) , a much 
more contineous "I/O bytes history" appeared.

Anyway , compared my output with some mkv files generated by mkvmerge  - 
observed the same mkvalidator warnings - clusters seemed to be limited by 
size / time,  not necessarily aligned on video key frame boundaries. One of 
the mkvmerge files I generated myself  using latest mkvmerge with default 
command line options.

mkvclean I have not yet tried.

Subject: [Matroska-devel] Anamorphic video plays as 3:2
Message-ID: <loom.20110817T102303-98@post.gmane.org>

I have an anamorphic video that is playing in MPC-HC as 3:2. If I switch MPC-HC
to use the internal matroska filter is plays at the correct 16:9 so I assume it
must be Haali causing the problem.

The info collected below from Haali seems to show that is does recognize it
being anamorphic, but for some reason it is playing as 3:2. Note that the window
does open to 16:9 initially for a fraction of a second before resizing to 3:2.

Subject: [Matroska-devel] Haali Media Splitter Bug with MP4 files.
Message-ID: <1313700269.68958.YahooMailNeo@web36703.mail.mud.yahoo.com>

Dear Author of Haali Media Splitter,


For some unknown reason, Haali Media Splitter Version 1.11.96.14 cannot demux this variable frame rate MP4 (http://www.archive.org/download/AdelikatTerrotimMindnomadY05h1sDsNewSuperMarioBros.In2108.08/nsmb-tas-adelikatterrotimmindnomady05h1.mp4) made with MP4Box Version 0.4.6-DEV-rev2735 correctly.? It plays the file at a constant 25 FPS instead of variable frame rate.? Media Player Classic - Home Cinema 1.5.0.2877 and VLC Media Player Version 1.1.11 internal demuxers play the file back correctly.? I cannot tell why this is happening as other variable frame rate MP4s created with the same MP4Box version works correctly.

Regards,

-Arick

OK. If that's files you encode, you may try to avoid too many frames
between keyframes, otherwise the seeking will be bad anyway. You never
know if in the file's lifetime you're going to need to seek in it (if
not you, tools may).

As for mkvalidator you can always use it with the --no-warn command line option.

Would it be possible to provide a small sample?

I use Haali's Media Splitter too. I'd like to test if that happens with
other players too.

Please use some hosting service for the sample like mediafire or similar.

Some time has passed and nothing against it came up.

Is there a process where new official tags will be approved and maybe
announced or does it happen silently?

Just in case it gets accepted. What I hope of course.

Subject: [Matroska-devel] Haali Media Splitter: MP4 Demux: 'twos' audio
	track not recognized
Message-ID: <j3krkk$rnb$1@dough.gmane.org>

Dear HMS developer(s),

we have a camcorder producing video files in an mp4 container, using the
mpeg2 codec for video and "twos" FOURCC uncompressed audio.  HMS
(current version, 03/03/2011) recognizes the video stream properly, but
not the audio stream.

A sample video is here (100 MB):
https://www.iat.uni-leipzig.de/datenbanken/iks/bunk/671_0036_01.mpeg2.MP4

I'd be happy if this can be fixed and will be available for further
details.  I'd try to provide a patch, but I'm not sure whether the mp4
splitter code is included in the "Core parser library" mentioned at
http://haali.su/mkv/ .

Best regards,
 Michael Bunk

You are right, that should be changed. Luckily I think it's safe to assume
noone ever used this (segment linking + chapter editions) for now.

Any objection ?
