[DCP-o-matic] ITU/EBU loudness in FFMPEG for dcp-o-matic

by Carsten Kurz

Just found this in a forum: https://tech.ebu.ch/docs/events/opensource13/presentations/open-source-loud… Seems there is an EBUR128 loudness meter filter built into libavfilter. Maybe one could use it in dcp-o-matic. - Carsten

[DCP-o-matic] Windows Notebook falling to sleep during Encoding went sent to background

by Carsten Kurz

YES, it IS a boring flic, indeed, but does that justify falling to sleep while rendering a DCP? 1.72.2/64 After starting the DCP job, I just switched to the Desktop to inspect a folder and left it like this. After a while I came back and the notebook is sleeping. After waking it up, it continues rendering without any messages or errors. I'm just wondering wether the encoded images/MXF are correct? Is this normal? I remember reading some issues about fixes against machines falling to sleep in some release notes. - Carsten

[DCP-o-matic] KDM - Playout window local time

by Carsten Kurz

Carl, how is DCP-o-matic dealing with local time/GMT when creating the KDM and during email transmission? Will it automatically convert local machine time to GMT according to machine time settings? Then how is $START_TIME and $END_TIME calculated and displayed? All KDM providers we dealt with so far automatically convert to local time for Email transmission notification text. That is because they have a location and time-zone associated to every cinema in their database. - Carsten

[DCP-o-matic] DCP-o-matic 1.72.0 released

by Carl Hetherington

Hi all, DCP-o-matic 1.72.0 was released. This is mostly to fix a bug causing crashes on analysing audio (and possibly also on DCP creation). We also have: Potential improvements in encoding speed, especially on fast clients. Allow specification of video frame rate for cases where content headers are read incorrectly. Support for different KDM formulations: Modified Transitional 1, DCP any and DCP specified. Thanks to Matthias Damm and Daniel Chauvet. Download it from: http://dcpomatic.com/download Best regards Carl

[DCP-o-matic] recursion

by Carsten Kurz

Right now it is not good for much, but still interesting - ffmpeg added J2k MXF support a while ago, and since dcp-o-matic uses ffmpegfor input, it is actually possible to feed a DCP-o-matic generated J2k-MXF (or from any other unencrypted DCP) into DCP-o-matic as source content. Right now, the only option then is to recompress it into another MXF, which is hardly exciting. But - wouldn't this be a starting point for 'unwrapping' and transcoding of existing DCPs to other formats, again by using FFMPEG, this time for ouput? - Carsten

Hi, Is there somewhere more details on syntax if using DCPomatic thru CLI? I've tried ">dcpomatic --help" and ">dcpomatic_cli --help" but there is not much to drink and I'm really thirsty... Thanks, Fred
