[MPlayer-dev-eng] [PATCH] damr d263 update mov demuxer

[adland123]

I made some sample 3gp files with nokia multimedia convertor 2.0 on windows to
test playback of AMR narrow and wide band audio of various rates.

playing these samples showed in the output
found unknown movie atom d263 
found unknown audio atom damr

with some research I found this document giving specs for atoms of types listed
above at
http://www.3gpp.org/ftp/tsg_sa/TSG_SA/TSGS_15/Docs/pdf/SP-020088.pdf

uploaded the .3gp samples into Mplayer hq incoming

patch is below
