[FFmpeg-devel] [PATCH 1/2] avcodec/mediacodec_wrapper: get api level via NDK method

From: Zhao Zhili <zhilizhao at tencent.com>

android_get_device_api_level() is a static inline method before API
level 29. It was implemented via __system_property_get(). We can do
the same thing, but I don't want to mess up with
__system_property_get.
