Compilation Error when Building Gizmo: AV_SAMPLE_FMT_S64 Not Declared

[allycatty]

I'm encountering a compilation error while attempting to build Gizmo. The issue seems to be related to the usage of AV_SAMPLE_FMT_S64 and AV_SAMPLE_FMT_S64P in the file gizmo/media/stream.cpp. The compilation command and error messages are provided below:

Environment:

OS: CentOS 7.9.2009
Python: 3.6.8

Possible Solution:

Inspect the usage of AV_SAMPLE_FMT_S64 and AV_SAMPLE_FMT_S64P in the gizmo/media/stream.cpp file and provide necessary changes or updates to address the compilation issue.

Let me know if you need any additional information or assistance.
