[android] Investigate adding FFmpeg extension

[3493000]

How can I use an extended codec such as ffmpeg to parse AC3 format audio？ No matter whether I check the Prefer Software Decoder option or not, there is no effect, but the sound can be parsed under the windows unity editor.

Unity version: v2020.3.181f1 WindowsEditor AVPro Video version: v2.3.1 (plugin v2.3.0f1-core) Operating system version:Android 10 Device model: SHARK KLE-A0 Video specs

I compiled and integrated the two decoder aar packages of vp9 and opus into the unity plugin folder. It seems that the apk that I typed has no effect.

Hi @3493000

AC3 is not supported by any Exoplayer extensions, except FFmpeg. We currently have no way of adding this, although would be something useful to look into.
