Hi all:
When I just doing the driver for us chip, we would request the

Do you mean the start code prefix 0x000001? It depends on the codec,
VA-API has this requirement for HEVC, but no for AVC.
For AVC, I don't think the existing softwares using vaapi send the
prefix to driver, you have to workaround it in your driver. but if the
application is developed by yourself, you may send the prefix with
setting the right slice_data_offset, so other drivers can work well
with your application.
I see thank you. I think the Intel could handle the offset. So I think
it could be regard as a bug for Gstreamer. I would report the Gstreamer.
