Subject: [Matroska-devel] Question,
	avc units don't start with 0x000001 in matroska
Message-ID: <CAGKQ+v9kUPfuWwXnT=+6B8aPrCR+iVf4r3+8Mg1A5+av=1drEw@mail.gmail.com>

Hi,

I'm trying to decode test5.mkv in the test suite (
http://www.matroska.org/downloads/test_w1.html ).
However, the decoder which I'm using doesn't decode any pictures,
without any error, even how many samples I input into it.
I took a look into the file and realized its each sample starts with
something like 0x00 0x00 0x51 0xd0, my guess was each AVC sample
should start with 0x00 0x00 0x00 0x01.
I compared other files, .mkv and .mp4, both files comes from the same
content, I used a software called superC to make them, and checked
couple samples and confirmed those has the same samples except for
4byte at the beggining of each sample as I mentioned above.
Those .mkvs don't have header stripping I believe.

Am I missing something on leading bytes of avc samples? What does
those bytes mean more than delimiters?

I'd appreciate if you could give some time for me, thanks!

Makoto

The codec used is not AVC/H264. It's either Theora or "DivX".

My bad, the codec in use *is* AVC. And there is no header compression
involved. That's as far as my knowledge of AVC goes. What is sure is
that no data is missing for playback as this file plays fine
everywhere.

Hi Steve,

Thank you for your time.
Yea I understood this is an issue about more AVC than matroska.
I'll re-confirm that I'm passing all samples into decoder correctly.

Thanks,
Makoto

Hey,

AVC is stored in Matroska in the same way it is stored in MP4.

The marker (0x00 00 00 01) is only needed for elementary streams in
order to find the start of the next unit. In containers like Matroska
and MP4 each unit is instead prefixed with a length field. The size of
this length field is stored in the AVCC (C-style pseudo code:
"length_field_size = (((unsigned char *)AVCC)[4] & 0x03) + 1") which in
turn is stored in CodecPrivate. The length field is usually 2 or 4 bytes
long.

Kind regards,
mosu

Hi there,

will there be an option to enable mkv thumbnailing with haali x64? Or 
is there already one? I couldn't manage to configure the splitter.x64.ax 
via rundll32.exe the same way I did it with the splitter.ax :/ (no such 
entry point).

Hi Mosu,

You're right, what I was seeing in the MP4 case was the binary data
which marker had been already replaced from the length field.
So I added codes to switch leading bytes for mkv as well, and the
decoder gave me the image!

Though I'm still having errors after decoding couple frames, it should
be another problem.

Thanks for all of you who have taken time for me!
Makoto

Subject: [Matroska-devel] AAC in .TS files bug
Message-ID: <loom.20111028T051650-388@post.gmane.org>


Sorry if this is already reported but I've searched and cant find
ref to TS files although other AAC problems are mentioned.

Using MPC for playback I cant get any files with AAC in to work
If I remove Haali and install LAVI filters the same files play (but with video 
problems) No other changes were required.

Below is the spec for a sample file - this was produced using the UK 
version of Humax HDR Fox T2 PVR. This will fail with Haali.
Unfortunately these boxes can only produce AAC audio on HD recordings; If the 
AAC etc. is stripped out the video stream plays OK.

I hope this info is of use as the toolnix chain fails if halli does not work:
This data was created by : MediaInfo 0.7.50
A sample Humax .TS specification that fails with Haali is:

That is a misconception. MKVToolNix does not use DirectShow in general
and Haali's splitter (or any other third party splitter) in particular
at all.

Fair enough  Mosu - all I know is it stops working if I remove haali. Perhaps I 
have something else in the chain that most people dont - I'm not very familiar
with it.

I really came back just to indicate that MKV files with AAC in also fail to 
playback with haali installed - it isnt a TS specific issue.
Also to point out this may be a case of missreading the stream type as 
sometimes the aac gets recognised as an unknown video stream or as mpeg-1 audio 
mono (?) by the media player - Yet the media info program I mentioned above 
always recognises it correctly.

Hope thats helpful too.
