error in building ffmpeg

[Mahesh Shivhare]

Hi all,
I want to enable all the codecs from ffmpeg (not all ;) at least MP3,
AAC, MPEG codec) so I'm using ffmpeg configuration of "ChromeOS/linux/
arm-neon/config.h" for building ffmpeg.

but while building I'm getting errors at linking step..
snip of error is attached..

Hello!

How ara you solved this?

If you chromium OS play mp3 now?

If you want to enable ChromeOS codecs in your private builds, build with USE=chrome_media as mentioned here https://code.google.com/p/chromium-os/issues/detail?id=14380. Enabling all codecs is not supported and will not work without additional work. If that's what you're interested in, you'll need to start with:
