[FFmpeg-devel] [PATCH] fftools/ffmpeg_demux: fix memory leak on error path

[LuMingYin]

In the file ffmpeg_demux.c located at /FFmpeg/fftools/, a pointer variable named ic is defined at line 1531. At line 1589, the program allocates a dynamic memory area for it using the function avformat_alloc_context. When the if statement at line 1668 evaluates to true, the function returns at line 1673. Throughout this process, the dynamic memory area pointed to by the ic pointer is not deallocated, resulting in a memory leak.
