[MPlayer-dev-eng] [PATCH] fix realaudio in mkv

[Roberto Togni]

Hi all,

 this patch adds audio packet descrambling to mkv demuxer and changes
extradata to conform to the new ad_realaudio decoder interface. The
same extradata format and packet order is also used by lavc real
decoders.

There is one problem created by this patch: in the old version the
codec filled sh->i_bps (nAvgBytesPerSec) based on the flavor value,
while now the codecs don't do it anymore (and that would not be possible
anyway with the lavc codecs). In real demuxer i solved the problem by
taking i_bps from the MDPR header, is there some field in matroska that
can be used to fill that value? Else the only option is to create a
table with bitrates like it's done for sipr codec (sipr is the only
codec where flavor or bitrate is used to select the codec subtype).

Only cook is tested (samples/Matroska/realaudio/nosound.mkv).


Mosu, can you comment on this?

Ciao,
 Roberto
