Sorry, now I got what you mean.

Why do you say qstrip+strip anyway? qstrip does strip itself:

> # Strip quotes and then whitespaces                                                                    
> qstrip=$(strip $(subst ",,$(1)))                                                                       
> #"))

So I would do:
-ifneq ($(BR2_PACKAGE_FFMPEG_ENCODERS),"all")
+ifneq ($(call qstrip,$(BR2_PACKAGE_FFMPEG_ENCODERS)),all)

If that's ok, it will be in the re-submitted patches.

Ahh yes, then just qstrip.

How can foreach break with extra spaces? I've been trying things as:
> BR2_PACKAGE_FFMPEG_ENCODERS="   vorbis    flac  "
and they work ok.

BTW, that was with GNU make. Relevant?

Not the foreach, but the ifneq (....,"all") would break if the user
ended up setting it to "all " or " all" or similar.

[Buildroot] Add ffmpeg support

[Luca Ceresoli]

FFmpeg is a complete, cross-platform solution to record, convert and stream
audio and video. It includes libavcodec - the leading audio/video codec library.

This patchset adds support for building ffmpeg in buildroot.

Most high-level options are provided via kconfig options, and there is a hook
in the last commit to allow passing .configure any parameters not directly
supported (very handy for machine support, for example).

Note that this support is much more complete than the one in bug 401
(https://bugs.busybox.net/show_bug.cgi?id=401).

Thanks,
Luca

ffmpeg: add new package
ffmpeg: add commandline programs
ffmpeg: allow customization of codecs, (de)muxers and other components
ffmpeg: add user-defined configure parameters

[Buildroot] [PATCH 3/4] ffmpeg: allow customization of codecs, (de)muxers and other components

[Luca Ceresoli]

Add the option to customize the list of decoders, encoders, muxers, demuxers,
parsers, protocols, bsfs and filters to be built into ffmpeg, and to compile or
exclude input and output devices.

I would suggest you use qstrip + strip here as well, so it doesn't break if the
user accidently added extra spaces or so.
