Digital Cinema Packages / Re: Open Source DCP Workflow
« on: April 18, 2018, 04:59:50 PM »
Is there a way to extract frames from two different files in the same ffmpeg procedure - say, a feature and a bonus content video - such that the numbering flows properly? I've tried batch renaming of files after the fact with both thunar and some Windows-based app, with horrible results... frames get renamed out of order regularly. Most likely, we'd be talking three files, with the third being the equivalent of a 5-second MOS in between. Thanks.

Sorry for the late reply. This was my own stupidity, leaving out dpkg in the command. This thread can be closed.

I've tried the DCP-O-Matic forums, but my password isn't working. When I ask for a new password, it tells me it can't find that email. When I try to register, it tells me that email is already in use... This has just been a nightmare.

And on top of it, no one has responded in any forum anywhere that I've asked about this. Lovely.

No one else has had a single issue with installing?

Digital Cinema Packages / Re: dcp_inspect no longer installable

OK, this post helped me figure it out:
I believe I had to mess around with the wget and dpkg commands a bit in order to get, specifically, the 'libpng12-dev' package.

I did get some (evidently minor) error when I ran "digital-cinema-tools-setup" afterwards, something about a certain jpeg2000 tool that was not available. But the inspection tool appears to be working without it.

Is there any way to update the setup tool for installing dcp_inspect? This is what I get on a fresh install of Xubuntu 17.10:

Code: [Select]
Package libpng12-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libpng12-dev' has no installation candidate
apt-get: Failed to install basic requirements

OpenDCP / Re: can't seem to get a flawless check with title name

I always get 4 hints, and no, I don't lose any sleep over them, but I do find it curious why I cannot get rid of them.
Code: [Select]
Naming convention: 3 parts missing: content_kind, territory_rating, package_typeThe only one that is actually ever missing is the rating, since nothing I encode ever has an MPAA rating. What gives?

I realize that this may or may not be verboten here, but I've tried posting to their forum and no one responds. Besides, I noticed Terrence's name attached to it as a dev, so...

I can't install DCP-O-Matic on my Linux box, only on the Windows side of it. It keeps saying
Code: [Select]
Couldn't find any package whose name or description matched "dcpomatic_2.10.5-1_amd64.deb. Unable to apply some actions, abortingThis would suggest that I've either misnamed the file in the install command, or that I'm in the wrong directory. Neither is the case, I assure you. I cd to the correct directory, and I drag-and-drop the file into the install command.

Has anyone else had issues with this, and how did they get around it? Thanks.

I forgot to follow up on this in-thread. Adding the switch "-depth 8" in the mogrify command resolves this issue. For example:
Code: [Select]
mogrify -background black -gravity center -depth 8 -extent 1998x1080 *.tiffThanks for your help Terrence.

Digital Cinema Packages / 7.1 Channel Mapping - Feature Request
« on: April 26, 2017, 01:56:04 PM »

Can the next version of OpenDCP either place the rear surrounds on channels 11 and 12 by default (with mutes in 7 through 10) or give the user the option to decide where these channels should go? I realize that there is evidently no effective "standard" for this beyond the first six channels, but the recommendation from Dolby and others is to have HI/VI in channels 7 and 8. Indeed, most theaters' sound systems are set up to expect the Dolby-recommended layout, and 7.1 DCPs created on OpenDCP do not play properly without some tinkering. Thanks.

Digital Cinema Packages / Re: Audio Format Metadata
« on: April 25, 2017, 07:48:38 PM »
I have some clarification: firstly, in case there was any confusion, ingest and Playback are not a problem. These are fully functioning DCPs. Secondly, the issues we are seeing seem to reside mostly at the TMS/LMS level. Some of these systems, like the Hollywood Software TCC3, fetch higher-level playback instructions from the CPL (higher than, say, first and last frame.) Among these is the audio format.

So, when the theater staff is composing their feature SPL, and this playlist contains DCPs of differing audio formats, the TCC3 will automatically place the appropriate format cues wherever needed.

I suppose, then, what we're really discussing here is a feature request. Can writing these optional parameters to the CPL be included in a future version of opendcp? Thanks.

Based on this page, I need to add the following lines to the CPL:
Code: [Select]

I'm drawing a blank as to how to do that, however. I believe I need a decent XML editor (will just a basic text editor like Mousepad do the job?) and then I need to edit the CPL length within Assetmap by the above number of characters. Do I need to recalculate hashes as well?

Also, where would the lines above go, precisely? Would it be under MainSound, at the same level as EditRate, IntrinsicDuration, etc.? Thanks.

So, what exactly am I doing wrong? We tested several of our spots, and compared them to lab-issued trailers. The meta:MainSoundConfiguration tag appears to be missing from our DCPs.

How do I add the audio format of my DCPs to the CPL metadata. Several of the systems our exhibitors use ignore the name (they don't bother parsing out the "20", "51" or "71") and they cannot or will not simply detect the number of streams. They are looking for direction from the CPL, evidently a line like "cpl-meta:MainSoundConfiguration".

I'm not seeing options for this in OpenDCP, unless it has something to do with adding digital signatures. Is that it, or do I have to manually edit the CPL? If the latter, how would I do that?

We'd been led to believe that the Dolby 850 would automatically detect a 5.1, 7.1 or Atmos DCP and switch formats accordingly. I'm not so sure anymore. Please advise. Thanks.
