[Mp4-tech] Decoding error after Packet loss

[Yiting LIAO]

Hello all,
I encoded the foreman sequence using baseline profile (GOP 30, RTP size: 
100 byte) and applied some packet losses. When decoding, I got several 
problems:
1. When frame 15 is lost, I got the following error message:
RefPicList0[ num_ref_idx_l0_active_minus1 ] is equal to 'no reference 
picture', invalid bitstream
But it is OK if frame 8 or 12 is lost.
2. For another loss pattern, I got the error message:
duplicat frame_num in short-term reference picture buffer
**3. Sometimes, the decoder stopped decoding when too many packets are 
lost. Can I just keep copying the previous correctly decoded frame as 
the lost frame?
For example, the original video contains 100 frames and frame 80-100 are 
lost. So I would like to copy frame 79 as frame 80-100 and output the 
corresponding PSNR.
Any help will be really appreciated.
Thanks,
Yiting
