Hi,
I am developing a feature in my Android application where I want to
generate the video thumbnail of HLS video.
I tried to generate the thumbnail using
Android native MediaMetadataRetriever but it failed for HLS video so that
is the reason I have decided to use FFMpeg and the only feature I want to
use is to generate thumbnails for HLS videos.
I have tried adding the gradle dependency into my app and it's working as
expected.
implementation("com.arthenica:ffmpeg-kit-https:6.0-2.LTS")
The problem here is that the above dependency increases my APK size
tremendously, previously my APK size was approximately 30 MB and after
adding the above dependency the apk size increases to 130 MB.
In order to reduce the APK size I have decided to build and generate the
.aar file manually and include only those architecture and libraries which
are must.
I don't have much knowledge in generating the .aar file but after following
the documentation I generated it successfully and added it to my project
but it crashed the app start.
Now based on my requirement can you please suggest what all libraries
should I include in the aar build process so that the apk size doesn't
increase and can generate the thumbnail from HLS video.

Crash:
