Re: [Audacity-devel] Adding "Import Audio" support on ARM

[Ajay G. <aja...@gm...>]

Well, just came across the note at
http://manual.audacityteam.org/man/FAQ:Installation_and_Plug-Ins#installffmpeg

##################################################################################################
*FFmpeg version information:* Audacity 1.3.8 to 1.3.12 inclusive did not
compile or work correctly with FFmpeg versions greater than 0.5, and 1.3.13
to 1.3.14 inclusive did not compile or work correctly with FFmpeg versions
greater than 0.6. If you are not using the latest version of
Audacity<http://audacity.sourceforge.net/download/>,
please upgrade.

Thus I downloaded "audacity-2.0.0" and built it on X86 F14. "Import Audio"
WORKED !!!

However, when I did the same on ARM, "Import Audio" DID NOT WORK.
Instead, it showed the following error logs on startup ::
