[Mp4-tech] [H.264] Loss of B frame

[Marco D'Orlando]

Dear experts,
  I use H.264 encoder version 101 in order to test the decoder resilience.
The sequence is encoded as an IBPBPB structure and every frame is fit in a single packet
so the loss of a packet will results in a loss of a whole frame.
The decoder uses Frame Copy error concealment but when I remove a B packet from the bitstream some error occurs.
The question is:
Is the decoder able to manage the loss of B frames?
Kind regards,
Marco
