I now have access to three Sony 515 all with different software versions and am currently preparing test material to check wether the problem still exists.

So, it seems, none of the recent additions to DOMs wrapping, like HMAC,MCA, etc. changed anything about our Sonys inability to play encrypted SMPTE content created with DOM. Encrypted/Unencrypted Interop plays fine, as does unencrypted SMPTE. This is with an outdated Sony software version 1.22.2 See attached screenshots. On first sight, all looks good, content and KDM is indicated okay and associated properly, time windows is indicated. In the library, IOP CPL is indicated as playable, SMPTE version as non-playable. If you still try, you get an error. At first it does look as if the KDM is malformed, but I can hardly imagine what could go wrong there? Let's see what these two other systems say. |

@Carsten: was there any update on this? |
|
It seems I severely underestimated the effort needed to download and play two 25MByte Test-DCPs. So, I have one report about non-working encrypted SMPTE DCPs on a Sony running 1.30.6, and still waiting for a report with the most current software. I carefully kicked him again, maybe today...

Carsten reports that DoM's KDMs don't work even on the newest Sony software. |

Hi, lemgeo reported an ASSETMAP issue. <?xml version="1.0" encoding="UTF-8"?> & <?xml version="1.0" encoding="UTF-8" standalone="yes"?> Maybe the working packages used the second way... |

Yes, I tried all three possible options. I have access to a Barco ICMP, and tested encrypted and non encrypted SMPTE and Interop Versions on both our Sony and the Barco. Both encrypted IOP and SMPTE worked on the Barco (with the modified transitional version), but all SMPTE versions failed on the Sony. I know that the Sony will play encrypted SMPTE in general, as I had received a few encrypted SMPTE test DCPs, and the Sony will play ATMOS DCPs. As a side note, I know that another (commercial) DCP mastering/encryption software has/had the same issue (at least it was restricted to encrypted SMPTE on Sonys, and the error message was the same). Unfortunately, my contact to them has dried out, so I don't know what has become of it. Carl and I have come up with something else to narrow it down, I just need some time to prepare this test thoroughly. I think we are close to a solution.

Have asked Carsten to test a DCP derived from libdcp 33c2c1ddee9638fc4e59dbfdbeee2fb540778819 |
|
Verification and Validation both positive with the latest SMPTE test DCP. Are we emotionally ready to test encryption and KDM yet???

Possibly fixed in 2.13.107. |

Believed fixed in 2.13.108. |
