 It won't copy "StreamTitle" from input to output while transcoding input
 from mp3 to aac.
 I'm using version v2.6.1 compiled by me on ubuntu 14.

 I try simpliest transcoding with -c:a copy option and sending it to
 icecast v2.4.1 and as a client I'm using latest winamp and vlc.
 In booth player as title is showing only the mount point (in this case
 mystream) from icecast:

 {{{
 icecast://source:mypass@x.x.x.x:8000/mystream
 }}}
 and not the StreamTitle from input file.
 Why and how can I just pass it from input to output?
 I don't think that problem is Icecast, because I try to stream with SAM
 Broadcaster and in Winamp I see updated StreamTitle in real time.
 Here is the command line:

 {{{
 /root/ffmpeg_sources/ffmpeg*/./ffmpeg -stats -report -i
 http://streaming.streamonomy.com/ElectricFM -c:a copy -content_type
 audio/mpeg -f mp3 icecast://source:mypass@x.x.x.x:8000/mystream
 }}}
 and here is the output:

 The main usage of transcoding would be:

 {{{
     /root/ffmpeg_sources/ffmpeg/./ffmpeg -stats -v 1024 -report -i
 http://stream2.electricfm.com -acodec libaacplus -ar 44.1k -ab 40k -ac 2

 icecast://source:mypass@x.x.x.x:8000/electricfm@64k < /dev/null >/dev/null
 2>/var/log/ffmpeg.log &
 }}}
 but it gave me same result..not showing "StreamTitle" from input to
 output!

 I try with options -map_metada 0:s:0 and others option, but without
 success.
