GStreamer 1.16 error

[Andrew Esh]

I ported a large Native library that uses GStreamer to version 1.16 last
summer. For internal development reasons, I tried doing the port to a
number of different API levels, with the goal being to get it to build/run
on 29 (Android Q). I got the port working on many releases of the NDK up to
20. I remember that there was one NDK/API combination that was not working.
It was in the NDK 18-19/API 27-28 range. I'm sorry I don't have specifics.
It was a while ago.

I do know that I got GStreamer 1.16/NDK-20/API 29 working. It took adding
some tool path modifications to cerbero/config/android.config for all
architectures except armv7. These were needed due to NDK-20 having renamed
many of the tools to have the architecture triplet prepended. The NDKs
prior to r20 do not need that.

My advice is: Upgrade to NDK r20. The further back one goes in NDK
revisions, the less support there is for later Android OS releases. The
NDKs are meant to provide backward compatibility. The default choice should
always be to move forward.
