 RE: ffmpeg 1.1 (build 2013-02-09)

 2 bugs:
 1/ when aac is the output source, source tags are not copied

 2/ when aac is input, ouput tags have issues with some non EN chars

 '''Quid is it linked to any aac encoder or just libvo_aacenc
 '''

 First let's test source is MP3

 With:

 {{{
 ffmpeg -i withTagsMp3.mp3 -map_metadata 0 tagTestaacNoTagCopy.aac
 }}}


 no tag are copied, no warning or error

 while both are OK:

 {{{
 ffmpeg -i withTagsMp3.mp3 -map_metadata 0 tagTestmp3OK.mp3

 ffmpeg -i withTagsMp3.mp3 -map_metadata 0 -id3v2_version 3
 tagTestID3v2mp3OK.mp3
 }}}

 Second let's test when source is AAC


 {{{
 ffmpeg -i withTagsAAC.aac -map_metadata 0 aac2mp3RUSSIAN_FAILS.mp3
 }}}


 Here French characters are copied, but Russian fails (note withTagsMp3.mp3
 is OK with Russian)
 Returns an error:

 {{{
 "[aac @ 000000000222d3e0] channel element 2.0 is not allocated
 Error while decoding stream #0:0: Error number -1 occurred"
 }}}



 {{{
 ffmpeg -i withTagsAAC.aac -map_metadata 0 aac2aacFails.aac
 }}}

 Here no tags are copied at all !

 {{{
 "[aac @ 000000000222d3e0] channel element 2.0 is not allocated
 Error while decoding stream #0:0: Error number -1 occurred"
 }}}
