How KMP External Codecs Work with libvlcjni.so and VLC Media Player Library

1. KMP Player and External Codecs: KMPlayer (KMP) can use external codecs to support additional audio and video formats that may not be natively supported by the player itself.
2. VLC and libvlcjni.so: VLC Media Player, especially in its Android implementation, uses libvlcjni.so, a native library file. This file is part of the VLC architecture that enables the use of the VLC engine to decode and play a wide range of media formats.
3. Integration with VLC Codecs: While KMPlayer can use its own external codec packs, VLC Media Player relies on built-in codecs provided through libvlcjni.so. This library contains the necessary components to handle most common codecs without the need for external files.
4. Compatibility: KMPlayer can function alongside the VLC libraries when used on the same device, but they operate independently. KMP’s external codecs do not interact directly with libvlcjni.so. Instead, VLC leverages its comprehensive library of codecs embedded within the .so file to decode media.
5. JNI (Java Native Interface) Binding: libvlcjni.so provides JNI bindings that allow the Java-based VLC media player to communicate with native code, enabling high-performance media decoding and playback, which KMP handles separately using its own architecture.
6. External Codec Handling: KMPlayer users may install additional codec packs to extend media support. In contrast, VLC generally does not require external codecs, as libvlcjni.so supports a wide range of formats directly.
7. Performance Optimization: Both players optimize media playback, but VLC’s use of libvlcjni.so ensures that performance remains efficient by utilizing native libraries optimized for different platforms.
8. Platform Independence: While KMP’s external codecs may vary depending on the platform (Windows, Android, etc.), VLC’s libvlcjni.so ensures that codec support remains consistent across different operating systems without requiring additional configuration.

In summary, KMP uses external codecs to extend format compatibility, while VLC Media Player relies on the comprehensive libvlcjni.so library to handle media playback without needing separate codec packs. Both work independently to decode media content.
