OpenDCP / MPEG2-Interop still supported ?
« Last post by Carsten on May 19, 2018, 08:48:38 AM »
Hi all,

there have been a few requests towards MPEG2-Interop Support on the DCP-o-matic forum recently. While this is an almost archeological topic, there still seems to be a need for this in special closed markets. Does OpenDCP 0.30 still support MPEG2 wrapping? If not, is it possible to supply an older version that supports it? Any special prerequisites towards video and audio file formats that work?

Hmm, why don't you extract each part separately, then concatenate by renumbering each part separately? But maybe I don't actually understand the problem you have.

You can do it FFMPEG cmdline style, but the easiest way currently is to use dcp-o-matic's export function. Most other tools/options are actually just MXF-transcoders and need a bit of tweaking to create 1:1 representation of dcp->mp4. DCP-o-matic converts the actual DCP to mp4, that is, parsing the CPL, and attaching the audio in either multichannel or downmixed format.

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.

Hi,

do you know a software for transcoding a dcp with 51 to mpeg4 stereo ?
I know easy dcp, ffmpeg..
My problem is the down mix from 51 to 20. How can I do that ?

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?

OK, this post helped me figure it out:
https://askubuntu.com/questions/966757/libpng12-needed-for-17-10
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.
