Android 32bit - Issue playing some widevine content

[matthuisman]

attached is a good (h264) and bad (h265) zip of manifest, log and media files for two streams from a single service.

device is 32bit Android Nvidia Shield Tube (L1)

The h265 just shows black / distorted screen and audio is OK
h264 works fine.

I fixed this by enabling "try not to use secure decoder".

I wonder if these files give us a clue to how we can correctly play these without the above setting?

Same content on 64bit Android Nvidia Shield + other 64bit devices are fine.
Even Kodi 32bit on the 64bit devices is fine.

Only broken on 32bit kodi on 32bit device.
op1_h265_broken.zip
op1_x264_ok.zip

Also, when I play this same service but using their dash manifest, the 1080 H265 streams work,
But I suspect they could be different files.

Hey Matt
A couple of things.
Could you check if it fails the same when setting IA to video only?
Could you also provide a logcat for when it's failing?

No errors in the Kodi log... normally when we're feeding Kodi ffmpeg with incorrectly decrypted data it will show a bunch of ffmpeg errors in the log... none here. Makes me wonder if this is some sort of memory thing, or even a device issue. Hard to say!

Turns out the non-cmaf doesn't play either on the users system. I have another user with Google tv 32bit on android 20 and a different addon (stan) isn't working as well.

I'll try get logs etc.
But yeh, not a cmaf issue. But a widevine license issue

the h265 is hvc1 that should be dolbyvision
its possible that the problem is on device codec decoders, kodi has selected
2023-01-20 22:29:49.326 T:21096 info <general>: CDVDVideoCodecAndroidMediaCodec:: Open Android MediaCodec OMX.Nvidia.h265.decode.secure
but maybe should use OMX.Nvidia.DOVI.decode

on this purpose on Kodi 21 has been made various improvements
It is worthwhile to test and see what happens on debug log
