Comment (by domingo):

 The problem is connected to B-frames wrap around approach.
 VSSH format with B-frames is as following:
 Meta data contains [startcode][SPS][startcode][PPS]
 Frame #0: [startcode][SPS][startcode][PPS][startcode][I-picture]
 Frame #1: [startcode][P-picture][startcode][B-picture]
 Frame #2: [startcode]
 ...
 Decoder is supposed to output B-frame on step #1 and P-frame on step #2.
