[FFmpeg-devel] [PATCH] libavformat\file:Fix duplicate JNI symbols

[admin]

From: 联盟少侠 

The errors indicate that there are multiple definitions of several JNI (Java 
Native Interface) symbols in the FFmpeg library. Specifically, the linker 
ld.lld has found duplicate definitions for the following symbols:

- ff_jni_get_env
- ff_jni_jstring_to_utf_chars
- ff_jni_utf_chars_to_jstring
- ff_jni_exception_get_summary
- ff_jni_exception_check
- ff_jni_init_jfields
- ff_jni_reset_jfields

These symbols are defined in both libavcodec.a and libavformat.a archives, 
leading to conflicts during the linking process. The duplicates are found in 
the same source file ffjni.c, but they are being compiled into two different 
static libraries.

To resolve these errors, ensure that each symbol is defined only once across 
all linked libraries, or if these symbols are required in both libraries, they 
should be marked as weak symbols to allow the linker to handle them 
appropriately. Additionally, check for any build script misconfigurations that 
may be causing the same file to be included in multiple libraries.
