HI @MagedMYoussef - What is the value of ApplicationIdentification
in your CPL? You should not see this error for App 2E 2020 CPLs (http://www.smpte-ra.org/ns/2067-21/2020
), because the App 2E 2020 standard normatively references the version of Core Constraints you're quoting (ST 2067-2:2020). Older versions of App 2E, however, reference a version of Core Constraints that does require one or more Audio Virtual Tracks to be present.
Hi @fschleich - Here's the value of ApplicationIdentification
in the CPL
<ApplicationIdentification xmlns="http://www.smpte-ra.org/ns/2067-2/2020">http://www.smpte-ra.org/ns/2067-21/2020</ApplicationIdentification>
I can see it's the same as you mentioned, but somehow it still shows the "Missing Audio Virtual Tracks" error.
Can you share the CPL for troubleshooting @MagedMYoussef ?
Here you go @fschleich : CPL_V30425662_TB_DTO_IMFA_HD-SDR_23_zxx-178_TVMN3U5TB.txt
P.S. I changed the file extension from .xml to .txt for github to attach it.
Thanks, @MagedMYoussef. I'm unfortunately not able to reproduce the issue, the current master branch provides the following results:
fschleich@fschleich-macpro photon % photon_imp_validator.sh /Users/fschleich/Downloads/CPL_V30425662_TB_DTO_IMFA_HD-SDR_23_zxx-178_TVMN3U5TB.xml

I'm now seeing that you seem to be running v4.7.0, you might have to update to v4.7.2 or later for the 2020 features.
Hi @fschleich , Thanks for checking.
I did indeed run photon_imp_validator.sh
on the CPL and it passed without errors successfully. However, in our use-case we are actually using Photon as an SDK and it produces the following errors when trying to parse the same CPL.
ERROR-Unsupported sequence type or schema Tag: cc:MainImageSequence URI: http://www.smpte-ra.org/ns/2067-2/2020 [Photon version: 4.7.2],ERROR-Missing ApplicationIdentification in CPL [Photon version: 4.7.2],ERROR-The Composition represented by Id cd2ee0cf-1131-4726-89bb-399aa782ad1c does not contain a single image essence in its first segment, exactly one is required [Photon version: 4.7.2],ERROR-The Composition represented by Id cd2ee0cf-1131-4726-89bb-399aa782ad1c does not contain a single audio essence in its first segment, one or more is required [Photon version: 4.7.2]
We are using this function to parse the CPL from Photon SDK which seems to have issues with 2020 features: com.netflix.imflibrary.st2067_2.ApplicationCompositionFactory.getApplicationComposition
Hi @fschleich , any update on this?
Hello @fschleich ,
I am facing the same issue with the spring SDK version 4.9.3
any updates with this?
I'm getting the following error, when I run Photon on a CPL with no audio tracks.
ERROR-The Composition represented by Id XXXX does not contain a single audio essence in its first segment, one or more is required [Photon version: 4.7.0-SNAPSHOT]
According to the SMPTE ST 2067-2:2020 standard, audio tracks are not mandatory and IMP can contain video only. So, I think Photon shouldn't be throwing a FATAL error in this case.
Is there a plan for fixing this anytime soon?
