 Summary of the bug:
 When ffmpeg get live stream from specific device as input, it shows a lot
 of errors and not processing stream correctly:
 [h264 @ 0x327f3210] missing picture in access unit with size xxx

 It seems, this is error from libavcodec\h264_parser.c, function
 nal.type of these NALs is 6 (H264_NAL_SEI)

 Problematic behavior can be reproduced using attached file.

 How to reproduce:
 % ffmpeg -i libavcodec_h264_parser_c_parse_nal_units.mp4 -vcodec copy
 -acodec copy -f null /dev/null
 ffmpeg version git-master, 6.0, 5.1
 built on arm or x64

 Checked with 5.1, 6.0 and git-master with the same result.
