Steps to reproduce

  1. Launch the Canal+.

  2. Playback any 4K contents Live or SVOD:

For Live channels: zap to channels “Canal+ UHD” or “Canal+ UHD HDR” or “.2 UHD”:

Video link of one minute: Connexion Amazon : with channel “Canal+ UHD HDR”. In this video, you can observe the following issues:

  • all along the video, you can observed very short micro freeze (there every short micro freeze could be “Interlaced video” issues)
  • you can also observe video frame drops: at second 10, at second 26 and at second 53

For SVOD contents: any Canal+ / AppleTV+ contents with UDR/4K picto in the info page of the content.

Video link of one minute: Amazon Photos : AppleTV+ contents in Canal+ App S1E1 of “Chief of war”. In this video, you can observe the following issues:

  • The 11 first seconds of this video you can observed very short micro freeze specially in the faces of actors (there every short micro freeze could be “Interlaced video” issues)

The current behavior

During a playback of a 4K or HD video contents with HEVC codec Live or SVOD, the enduser can observed randomly video stuttering or video frame drops. The behavior is a little bit more visible with Live channels compared by SVOD contents.

With Canal+ App, Live UHD channels are 50 FPS and SVOD contents are 25 FPS.

The behavior is the same what ever the enduser selects AUTO/60Hz/50Hz in the display settings of Kepler UI.

This issue is not observed with HD codec AVC.

The expected behavior

No video stuttering or frames drops

Is this a blocker? Do you have any workarounds?

No workaround possible.

Issue reported with Canal+ beta tester / validation and projet team.

Issue very critical (under review to decide if blocker or not)

Hi @etienne_braud,

Thanks for reaching out! To help us investigate, could you share your VPKG and logs with your Amazon contact? A few further questions:

  • Is this impacting HD & UHD content only, or 8K content as well (given your mention of “.2 UHD”)?
  • Is this impacting any app you’ve tested with (given your mention of Apple TV+)?
  • Could you confirm network conditions were stable when testing?

  • Is this impacting HD & UHD content only, or 8K content as well (given your mention of “.2 UHD”)?

only contents with video codec HEVC (HD and UHD). There is no 8K contents with our App.

  • Is this impacting any app you’ve tested with (given your mention of Apple TV+)?

It impacts the Canal+ App only. Apple TV+ contents are playback in the Canal+ App. You can playback Apple TV + contents via the session “Chaînes et Apps” and then Apple TV+.

  • Could you confirm network conditions were stable when testing?

Yes, network is stable.

The VPKG is the one on production. Canal+ version 4.6.2.
