Digital Cinema Packages in VLC?

Postby nicholas_he » 06 Jun 2017 20:25

I know that DCP support was announced for v2.2.3 Weatherwax, but from reading some other threads, it sounds like the functionality was created, but not compiled into the general releases. Is that accurate?

It was very exciting to read the feature listed in the Weatherwax feature list, including encrypted DCPs with KDMs. Does anyone have any suggestions on working with DCP's in VLC for macOS?

Announced? not really, two years ago (16 Jul 2015) Jean-Baptiste Kempf prudently said: "I can provide a faster version, when I have time, to do 2K decoding on a normal machine."
The only CPU powered low cost app I know of is ‘dcpPlayer’ by digitAll Australia.
It's a very good DCP tester but it works under the Kakadu proprietary licence and
unfortunately for us MacOS users, we must install Windows through Bootcamp.

Today MacBooks all are GPU equipped, the way to decipher DCP's Jpeg2000 images in real time with an open source application would be to rely upon the GPU.

be patient, there is a faster OpenJPEG released three weeks ago:
http://www.openjpeg.org/2017/08/10/Open ... 0-released
it should help developpers design a DCP realtime player.

Waiting for it, you could have a look at the only open source DCP player working on the CPU
of current MacBooks, it's the 2.11.22 test version of DoM: http://dcpomatic.com/test-download
Note: In 'View', select 'Quarter resolution'.

version 2.2.7 Umbrella (sept. 2017) still can't.
but
good news: the latest 3.0.0 Tassinari opens DCPs and immedialy shows the third jpg2000 image of the j2c file with very good resolution, and a progressing play slider. :)

bad news: neither the next images nor the meta subtitles nor the audio pcm follow the slider... is it that the high image resolution --too high for my two core cpu mbp-- hinders the process ?
