--- Comment #3 from Fei <fei.w.wang at intel.com> ---
@Victor, update my commit log. Currently all our existed platforms support P
and low latency B frame. And I cann't provide correct information if the next
platform will also support P frame. So I will not mention the hardware info in
commit log. And both vaapi-driver and media-driver support this.
There is a new interface in libva to provide query:
https://github.com/intel/libva/pull/220, if the patch merged(need driver to
support it), we can write another patch to query if the hardware support it
before do the low latency B. But I think the property is needed, now all our
existed platforms support both P and low latency B, there should be a property
to let user choose the right path.
