uint32_t max_frame_width
 Frame size note: Picture resolution may change frame by frame. Application needs to allocate surfaces and frame buffers based on max frame resolution in case resolution changes for later frames. The source and recon surfaces allocated should be 64x64(SB) aligned on both horizontal and vertical directions. But buffers on the surfaces need to be aligned to CU boundaries.

 Reserved bytes for future use, must be zero.

◆ bits_per_second

uint32_t VAEncSequenceParameterBufferVP9::bits_per_second

Initial bitrate set for this sequence in CBR or VBR modes.

This field represents the initial bitrate value for this sequence if CBR or VBR mode is used, i.e. if the encoder pipeline was created with a #VAConfigAttribRateControl attribute set to either VA_RC_CBR or VA_RC_VBR.

The bitrate can be modified later on through VAEncMiscParameterRateControl buffers.
