Which one should I pick for a new project?

I can only help you understand the specific technical details of these two repositories, but I can't make a recommendation about which to pick for your project without knowing your requirements.

However, I can describe what each does:

[carguo/gsyvideoplayer] is a comprehensive video player library supporting:

• Multiple playback engines (IJKPlayer, Media3/ExoPlayer, MediaPlayer, AliPlayer)
• Advanced features like caching during playback, danmaku (bullet chat), filters, watermarks, GIF screenshots, ads, and multiple simultaneous playback
• Various protocols (h.263/264/265, HTTPS, RTSP, HLS, RTMP, etc.)

[hugeterry/coordinatortablayout] is a UI layout component that combines:

• A collapsing toolbar with header images
• TabLayout for tab navigation
• CoordinatorLayout for coordinated scrolling behavior

These solve different problems: gsyvideoplayer is for video playback; coordinatortablayout is for building collapsible tab-based layouts. You might use both together in the same app (e.g., a video streaming app with tabbed navigation).

For adoption risk: RepoPilot flags gsyvideoplayer as "WAIT — Single-maintainer risk" with a weak OpenSSF Scorecard (4.4/10), particularly lacking dependency update tooling and SAST scanning. Consider this if long-term maintenance and security updates matter for your use case.
