 Summary of the bug:

 i want to send my h264 encoded file to another rtp system, the rtp system
 need sps and pps before every keyframe

 How to reproduce:
 {{{
 % ffmpeg -re -fflags nobuffer -i ./guigu_1.mp4 -vcodec copy  -an -bsf:v
 dump_extra=freq=keyframe -f rtp -payload_type 96 rtp://127.0.0.1:59658

 does not generate  per gop  sps and pps

 ffmpeg -re -fflags nobuffer -i ./guigu_1.mp4 -vcodec libx264  -an -bsf:v
 dump_extra=freq=keyframe -f rtp -payload_type 96 rtp://127.0.0.1:59658

 works fine.

 ffmpeg version

 3.4.2
