Log Message:
Fix bug:
RPD-2173 [RP_Playback]: RP(Plus) crashes after seeking MP4(MPEG4) clips with audio \
codec AAC+ or EAAC+  RPD-2171 [RP_Playback]: RP(Plus) crashes after seeking certain \
M4V(MPEG4+AAC_LC) clip RPD-2158 [Jupiter_Playback][Plus RP crash after seek action \
2~more with 3GP clips(MPEG4_SP + AAC_LC] 

Description
=========== 
These three bugs have same root cause:Current seek logic in CMP4VideoFormat will \
cause the decoder functions called in different threads, So I refer to the seek logic \
of CRVXVideoFormat to avoid this multithreading issue,save the seek point first and \
tell the codec to seek when beginning decoding.
