 Summary of the bug:
 Hello ,Dear developers,
 I have encountered a memory leak issue while using ffmpeg version n7.2-dev
 and version 7.1.git. When I execute configure, if I enable -- enable-
 libx264 and -- enable gpl, the issue will be triggered. If I do not enable
 these two options, there will be no problem. Please confirm

 How to reproduce:
 unzip FFmpeg-n7.2-dev.zip
 cd FFmpeg-n7.2-dev
 ./configure --enable-libx264  --enable-gpl --cc=clang --cxx=clang++
 --toolchain=clang-asan --enable-cross-compile
 ./ffmpeg -i pocffmpeg test.mp4
