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
