When trying to install ffmpeg it fails with the error "ERROR: sdl2 requested but not found" during the configure phase even tho media-libs/libsdl2 is present on the system
possibbly related to bug nr 865907


Reproducible: Always

Steps to Reproduce:
1. set use flag sdl for media-video/ffmpeg
2. emerge media-video/ffmpeg
3. emerge fails with "ERROR: sdl2 requested but not found"
Actual Results:  
emerge fails with "ERROR: sdl2 requested but not found"

Expected Results:  
emerge installs media-video/ffmpeg with support for sdl

Reproduced issue in a container by using a binary for libsdl2.

This looks like a binary package issue with libsdl2 as it links against libdecor which isnt stated as a dependency.
Comment 7 Alfred Wingate 2024-07-18 23:25:47 UTC 
So the solution as a end user is to either install gui-libs/libdecor, avoid the binpkg or use a newer libsdl2 with libdecor properly configured in the buildsystem + deps (no binpkg available).
Comment 8 Eli Schwartz gentoo-dev 2024-07-19 16:37:20 UTC 
This is the same root cause as the confusion in bug 936020 due to the fact that it uses automagic.

    media-libs/libsdl2: fix automagic dependency on libdecor
    
    It is enabled and depended on for the 2.30 ebuilds which use cmake,
    although the cmake builds default to not building with libdecor support.
    
    It is not enabled for the stable 2.28 ebuild which uses autotools,
    although the autotools builds default to detecting libdecor and using
    it.
