error concealment in h264.c


In order to make sense with the EC. I comment out the functions that deal with EC in h264.c by defining:
#define ff_er_frame_start
#define ff_er_add_slice
#define ff_er_frame_end

Then use rand() to simulate 10% packet loss rate. But there is no \"gray block\" in the decoded pictures. Does the decoder copy the missing blocks from the reference picture? I could not find the relative code in h264.c. Need your help.

Best regards,
