Isn't that like with mpeg2? Take any piece out of a continous stream (TV
broadcast, ...) that starts with a sequence header (mpeg2) or IDR frame
(h264). In both cases there are B-frames before the I/IDR in
presentation order. Decoders should skip them as they can't get decoded
properly - neither with mpeg2 nor with h264....
