How to build ffmpeg with libwebp for android?

I need use the ffmpeg (v2.8) to convert mp4 to webp, how to build ffmpeg with libwebp for android ?

I googled, but have little information to build ffmpeg with libwebp.

I try to add the configuration:

--enable-libwebp 
--enable-muxer=webp
--enable-encoder=libwebp

but i got the following compile error.

ERROR: libwebp not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

The config.log is:

check_pkg_config libwebp >= 0.2.0 webp/encode.h WebPGetEncoderVersion
false --exists --print-errors libwebp >= 0.2.0
ERROR: libwebp not found using pkg-config
Solution

  • I solved the problem as the following steps:

    1. build libwebp by ndk-build
    2. add *.a and *.h into a folder, such as libwebp-armv7a, under the project
    3. link the webp without pkg-config

    The way that @halfelf mentioned in comments is for PC build, not for Android mobile platform.
