Bug 31376 – media-video/ffmpeg should use the X USE flag

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Wolfram Schlich (RETIRED) 2003-10-17 13:43:23 UTC]

ffmpeg won't compile when 'sdl' is set and xfree isn't installed.

solution: add
'X? ( >=x11-base/xfree )'
to DEPEND and change
'use sdl || myconf="${myconf} --disable-ffplay"'
to
'use X && use sdl || myconf="${myconf} --disable-ffplay"'
because ffplay depends on the Xlib of XFree86

Reproducible: Always
Steps to Reproduce:
1. don't install xfree!
2. USE="sdl" emerge ffmpeg

Actually ffplay includes X11/Xlib.h for no apparent reason, so if you just
remove that line from ffplay.c, you don't have problems, this is taken care
of in the 0.4.8 ebuild I just committed.

Great :-)

Well .. this should really have been fixed for 0.4.7 also - this bug still exist in the currently stable 0.4.7, see below:

Brian, have you contacted the ffmpeg developers regarding this issue? They might want to fix it upstream :)

[Comment 5 d0der 2004-05-14 00:35:36 UTC]

Created attachment 31396 [details, diff]
Ebuild patch that fixes the ffmpeg unneccessary xlib dependency

This is the same fix already in 0.4.8
