Widevine Crashes In Youtube Precertification Tests

Question

I am working with Cobalt for Youtube.

When passing EME Conformance tests, Widevine tests causes a crash on my Set Top Box

Do you have any idea what may be the reason for this crash?

Answer 1

Judging by No such session error, this could indicate a problem with your SbDrm...() implementation. Did you run NPLB tests? Try ninja -C out/linux-x64x11_debug nplb followed by out/linux-x64x11_debug/nplb. Replace linux-x64x11 with the name of your platform.

For the reference, NPLB is a conformance test suite for Starboard, see https://cobalt.dev/starboard/testing.html.

Answer 2

From your stack trace, there is no log related to cobalt and it indicates you are using Broadcom platform. It would be better to ask your Broadcom contact about this issue. It's highly possible that it is fixed in recent updates.

Answer 3

after running "ninja -C out/linux-x64x11_debug nplb" libnplb.so file is generated what should I do next to run nplb tests.
