MediaInfo(Lib) 0.7 - Reading information about media files

I have no idea about the reason they change the name and the position in the image for the same angle, but if they do not change the angle, 5.1 back = 7.1 side (both at 90-110°)

For MediaInfo, 90-110° angle must have only ONE name (and the discussion was about Side vs Surround).
Back is already reserved for 135-150°, it can't be reused for 90-110° whatever are the pictures and names, and you demonstrated with the image that your 5.1 channel have "surround" channels at 90-110°... So "Side", and not "Back (135-150°)

If the image is wrong about angles(if speaker position is right), another name for this "new" angle must be found ("Surround"?), so 5.1 would have Front+Surround, and 6.1 or 7.1 would have Front+Side+Back.
But in order to do this, I must be sure that speaker positions are not same (90-110°), and I currently saw no other angles...

About "Sub", I already spoke about it, I don't remember where, but people demonstrated that LFE and Subwoofer names are different, and that "LFE" is better, I use it. I don't display "Yes" because I hide "LFE" if it is not present. I admit this is not the best presentation because separation between the last field and LFE is not great, but this is the best I currently have (I am not sure that ", Back: L R, LFE: Yes" is better than ", Back; L R, LFE". And additionnaly, this is more difficult for translation, L and R are common and understable as Left and Right in the language of people so I let it as is, but "Yes" is a bit too much "english")

Note: I changed "rs" to "Back" for TrueHD

On http://www.dolby.com/consumer/setup/...ide/index.html , Dolby's website, 5.1 channels are named "Surround", not "Back"... I don't know where you saw this image.

[SeeMoreDigital]

I see...

I have taken new "lifts" from Dolby's web site for further reference: -

I told you so. Even the Architect alone (=Dolby Laboratories) calls them "Left and Right Surround" speakers!

Indeed they do...

Sufficed to say though... The "front" left, centre and right speakers are "surround speakers" too!

Personally... I prefer to have identified where all my surround speakers need to be located. ie: the ones to the "side" and/or the ones to the "back"

EDIT: FFdshow's "naming" convention is very understandable: -

Hi! Can you please check this thread? There is information about possible bug. Thanks.

I've been doing some testing with AVStoDVD, and it's transcoding some of my DVD compliant files because Mediainfo isn't reporting the Standard field for these files. The files in question are MPEG-2 @ 352x240, which is a valid NTSC DVD combination. It seems that 'NTSC' is only reported for files that are 720x480, but not 704x480, 352x480, or 352x240. Likewise, 'PAL' is only reported for 720x576, not 704x576, 352x576, or 352x288. The resolutions are also listed here:

For all those resolutions, could the Standard field also report 'NTSC' or 'PAL'?

Trusting http://en.wikipedia.org/wiki/NTSC#Li...d_refresh_rate , 240 lines is not NTSC. But I agree that theses digital resolution have NTSC or PAL TVs as target. I added theses resolutions as NTSC/PAL in the release of today (0.7.32).

[b66pak]

thanks a lot...

Zenitram, may I ask why there is no source package available this time? Or did I miss something?




[EDIT]

Never mind. I managed to manually check out the "v0.7.32" tags from the SVN repository.

A bit late, but the source package is avaialble.
This is exactly the same as the SVN tag 0.7.32, no need to update if you used the SVN.

Thanks for updating mediainfoDroplet for Mac OS X! Annoying bug: spaces in files path are not handled.

that was already reported, but i cant reproduce here (works with every type of path i could imagine here, spaces in path, spaces in file names, weird chars, etc). So if you have a clue on how to reproduce that, then i can do something?

mods: can someone split this from post 672 to a new thread with name:

(i did not expect a debate )

Bug reproduced when mediainfoDroplet is in a folder with a name containing spaces! See attached file.

Hi Zen,

I just thought you may be interested in this one...

I have a "7.1 channel" Dolby Digital Plus sample for you, which is not currently supported by MediaInfo... In-fact it's not currently supported in most applications.

I am able to play it on my Xtreamer (hardware media player) and send the bit-stream output to my Onkyo amplifier. So I can confirm it works.

Any chance you can provide support for such sources?

Here's a link to the source: http://www.megaupload.com/?d=Q4YSDD48

There is some info:
Audio
Format : E-AC-3
Format/Info : Audio Coding 3
Duration : 3mn 34s
Bit rate mode : Constant
Bit rate : 732 Kbps
Sampling rate : 48.0 KHz
Stream size : 18.7 MiB

(bit rate is wrong due to how the file is created)

I imagine!
Actually, you file has 2 E-AC-3 streams interleaved!
(One 7.1 frame, one 5.1 frame, One 7.1 frame, one 5.1 frame, ...)

On my ToDo list.
But there are some development to do, not quick, and my ToDo list is currently very long, so do not expect it soon.

Hi Zenitram,

Thanks for the information...

So it's two audio files in one. I wonder if this is the reason why TSmuxer GUI does not recognise it

As far as I know...

None of todays surround sound audio formats generate streams offering a dedicated "rear centre" channel...
