Subject [jira] [Commented] (TIKA-1156) AMR file not correctly detected
Date Mon, 05 Aug 2013 12:41:48 GMT

    [ https://issues.apache.org/jira/browse/TIKA-1156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13729470#comment-13729470

Emil Burzo commented on TIKA-1156:
----------------------------------

In wikipedia's codec list[1], there is a sample C reference implementation for AMR-WB+[2].

I tried to use the encoder from that implementation to convert a wav file to amr-wb+, but
ffmpeg doesn't recognize the converted file.

Either I'm doing something wrong, or it's using some newer specs? Sorry I can't help with
some samples.
