The upper user-space application will pass the reference picture list0/1 for H264 encoding and then the libva driver will use the info for the reference frame in encoding. > > I have a scheme where the decoder ack's received frames - With this > information I could resync without an IDR by carefully selecting the > reference frame(s).

As you know, the current encoding is based on hardware-acceleration. When more the reference frames can be selected, the driver will be more complex and then the encoding speed is also affected. > > -- > T. _______________________________________________ Libva mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/libva
