[Opensvcdecoder-support] is it a bug??? while using mplayer with opensvc 1.12

[Shuaijun Z. <sz...@re...>]

Hi there,

I changed the mplayer code to force the opensvc decoding the basic layer
only. But seems it can't work. No picture is decoded.
I tested it with the video_5 in opensvc sourceforge and my newly encoded
video (with the configuration files from opensvc). The results are same.

I changed the code in the file of libavcodec/h264c in mplayer to make sure
the opensvc is decoding the basic layer only. The code is as below.
let me know if I am doing something wrong or it is the bug in the opensvc
decoder, or the svc video is not correct...
thank you
Jason

I changed the **SavedId to 0, so that the decoding layer  is always basic
