[FFmpeg-devel] [RFC] Bump minimum required version of Android to 5.0

[Zhao Zhili]

We don’t have a minimum required version of Android in FFmpeg.
libavdevice/android_camera requires Android 7, Java MediaCodec
requires Android 4.1, and NDK MediaCodec requires Android 5.0.

Without an explicit version, it’s unclear for development and test.

Android 5.0 is released in 2014, is it OK to bump the minimum required
version to Android 5.0, or any other version you prefer?
