Hi all,
When trying to play DRM protected content, LibreELEC segfaults and restarts.
- Device: NanoPi K2 (S905 SOC, Mali-450 GPU)
- LE version: devel-20190915174406-76b3023 (master branch)
- Command used for compiling: PROJECT=Amlogic ARCH=arm DEVICE=AMLGX UBOOT_SYSTEM=nanopi-k2 make image
- Kernel version: mainline 5.3.0-rc8 (aarch64)
- OpenGL vendor: Lima
- Userspace: 32-bit (Python platform.machine() reports armv7l)
- Inputstream Adaptive version: 2.4.2
Tested with:
In both tests, playing video with WideVine will cause segmentation fault 
.
I hope someone can shed some light as to why this is happening...If further tests are required, please let me know what I should do. Better still, if someone has this or a similar device (any Odroid C2 users here?), please test if the same problem also happens with LibreELEC running on mainline kernel, so I know this is not specific to my device. Thanks.
