Can't compile with FFMPEG5 - Retroarch 1.10.0

[AngryPenguinPL]

Description

We have already migrated to FFMPEG 5 and when trying to compile Retroarch (1.10.0 in this case) I get a compilation error:

error: 'AVPicture' undeclared (first use in this function); did you mean 'AVPictureType'?
DEBUG util.py:634:     77 |       avpicture_alloc((AVPicture*)b->buffer[i].target,
DEBUG util.py:634:        |                        ^~~~~~~~~
DEBUG util.py:634:        |                        AVPictureType
DEBUG util.py:634:  cores/libretro-ffmpeg/video_buffer.c:77:24: note: each undeclared identifier is reported only once for each function it appears in

Which indicates incompatibility with the newly released Ffmpeg5. It is worth adding that if I use compact ffmpeg4 version, everything compiles correctly.

Expected behavior

All compiles fine with ffmpeg5

Steps to reproduce the bug

1. Upgrade ffmpeg to version 5
2. Try compile retroarch 1.10.0
3. See build error

Environment information

• OS: OpenMandriva Cooker
