Black screen on DRM videos in macOS Catalina with IQSV

On macOS Mojave DRM video works well.
for me, i'm using iMac19,2, need to disable forceOfflineRenderer with shikigva=1, in this case i am able to play Tv.app video, if not, there is only sound, no video.
Try to play this video.

confirmed, shikigva=1 bootargs, playable with quicktime player. but screenshot will be blank picture, due to DRM nature?
additional notes: with shikigva=1, VDADecoderChecker will report error,
VDADecoderCreate failed. err: -12473
An error was returned by the decoder layer. This may happen for example because of bitstream/data errors during a decode operation. This error may also be returned from VDADecoderCreate when hardware decoder resources are available on the system but currently in use by another process.
VDADecoderCreate failed. err: -12473
This bad decision. It breaks the hardware decoder.
Research is necessary.

It is too bad, so i decided to remove the shikigva=1 args, hardware decoder is more useful to me than playing DRM video.
I've also tried models which has no forceOfflineRenderer option according to /System/Library/PrivateFrameworks/AppleGVA.framework/Resources/Info.plist, e.g. use MacBookPro15,1 (without shikigva=1 boot arg) instead of iMac19,2 for my hardware (i5-8400+ RX470), this model also breaks hardware decoder by default
update:
defaults write com.apple.AppleGVA gvaForceAMDAVCDecode -boolean yes
fixed VDADecoderChecker error
You switched the decoder to AMD. This decision so-so, to us Intel the decoder is necessary because it is better.
Resolved in master.
@vit9696 just tried the new version of weg:
The video provided by @vandroiy2013 is playable with sound and image now.
But /Application/Video.app does not play, a new window flashes swiftly and then disappear.

sorry, it looks like a network error, Apple Tv is not playable in China now?

Same error code in Australia when I trying to download any episode. I can't even play it with always black screen and 0:00. This might not be a regional issue. System 10.15.1 built with OC 0.5.3 and WEG 1.3.5
Apple TV requires hardware decoding, it will not work.

But Hardware decoding already works, i’m on UHD630+ RX 470
See post 2 , On Oct16 i was able to fully play Apple TV with shikigva=1, i was also able to hear sound without shikigva=1, but today, i can’t even hear sound, the new window just disappear quickly, downloading does not work. I have no idea what went wrong.
You confuse service TV+ and movies shop in TV.app(as in iTunes).
Movies from shop it is solved in the master.
But service TV+ has problems with IQSV.

wow, thanks for the info, checked again, Apple's product name is confusing me, but i'm gonna make it clear, on /Application/Video.app there are 5 tabs, only films in Movies are playable.
@vit9696 thanks for the update and patch.

Dose IQSV means Intel Quick Sync Video? Any plan to solve this IQSV issue?
Thank you.
