[FFmpeg-user] Issue Crossbuilding ffplay with openembedded

[Rickoo]

HI,

Im using 2.1.1 of ffmpeg because I want to use it as a depend to crossbuild a framework based on it, and tested with this version, might work with recent version but since i dont know...

About the configure options, im not sure yet which libs i am going to need for my application later so i just added some. (and i wasnt sure about the -ldl option, just saw this on a website).

Config.log:

This is horribly outdated, why are you using it?

You don't use libass, why did you add it to depend?

Not sure about libx11...

Unrelated: None of your external libraries need 

--enable-gpl why are you using it?


> --enable-libtheora --enable-libvorbis 


> --extra-libs="-ldl" 


Why is this necessary?

Is there a bug that (is reproducible with current git head 

and that) we should fix?


> --enable-ffplay


This is useless, it is the default (and as you found 

out, configure does not warn about it).

Please remove it.


Please post the content of config.log starting with 

"check_pkg_config sdl" until "check_header linux" or 

"check_header sys".
