[h264_vaapi @ 0x559993432140] Driver does not support some wanted packed headers (wanted 0xd, found 0).
[h264_vaapi @ 0x559993432140] Driver does not support packed sequence headers, but a global header is requested.
[h264_vaapi @ 0x559993432140] No global header will be written: this may result in a stream which is not usable for some purposes (e.g. not muxable to some containers).
