Which one should I pick for a new project?

I can only answer questions about google/exoplayer or pqpo/smartcropper.

However, I can clarify what these repositories are for to help you understand which might be relevant:

google/exoplayer is a media playback library for Android. Per the README, [this project is deprecated](README excerpt). As stated: "This GitHub project is deprecated. The latest version of ExoPlayer is published as part of AndroidX Media3" and "As of 2024-04-03 we have stopped pushing commits to the dev-v2 branch." If you need a media player, you should use androidx.media3 instead, not this repository.

pqpo/smartcropper is an image cropping library optimized for documents, IDs, and business cards. It's an active project with recent optimizations using machine learning (TensorFlow HED network).

Decision:

• If you need media playback: Don't pick google/exoplayer—migrate to androidx.media3 instead.
• If you need intelligent image cropping: pqpo/smartcropper is the appropriate choice.

These solve different problems, so the "right" pick depends on your feature requirements, not a general recommendation.
