Hello All,
I am new to roku development. I am implementing a playback in channel and using below canPlay4k method in my TCL Roku TV (model: 55S403).
I see crash. Appreciate any help as I am currently stuck with this issue
* if devinfo.GetModelType = "STB" and hdmi_status.IsHdcpActive("2.2") <> true
'Dot' Operator attempted with invalid BrightScript Component or interface reference. (runtime error &hec)
Function CanPlay4K() as Boolean
dev_info = CreateObject("roDeviceInfo")
hdmi_status = CreateObject("roHdmiStatus")
' Check if the output mode is 2160p
video_mode = dev_info.GetVideoMode()
if (Left(video_mode, 5) <> "2160p")
return false 'output mode is not set to 2160p
end if
print "Inside CanPlay4K "
if hdmi_status = invalid
print "hdmi_status invalid "
end if
' Check if HDCP 2.2 is enabled, skip check for TVs
if devinfo.GetModelType = "STB" and hdmi_status.IsHdcpActive("2.2") <> true
return false 'HDCP version is not 2.2
end if
' Check if the Roku player can decode 4K 60fps HEVC streams or 4K 30fps vp9 streams
hevc_video = { Codec: "hevc", Profile: "main", Level: "5.1" }
vp9_video = { Codec: "vp9", Profile: "profile 0" }
can_decode_hevc = dev_info.CanDecodeVideo(hevc_video)
can_decode_vp9 = dev_info.CanDecodeVideo(vp9_video)
if can_decode_hevc.result <> true OR can_decode_vp9.result <> true
return false 'device cannot decode 4K HEVC AND VP9 streams
end if
' (Optional) Check if the Roku player decrypts inside a TEE
drm_info = dev_info.GetDrmInfo()
if Instr(1, drm_info.playready, "tee") = 0
return false 'device does not decrypt inside TEE
end if
return true
End Function
