Unused definitions #353

Open podborski opened 2 weeks ago

podborski commented 2 weeks ago

There are 5 definitions in the spec (section 2) that are never used in the spec text:

Altref
Block scan
Golden frame
Raster scan
Switch Frame

wantehchang commented 2 weeks ago

"Switch frame" is referring to the SWITCH_FRAME value (3) of the frame_type syntax element in the uncompressed_header( ). "Altref" and "golden frame" are similarly referring to reference frame types, although AV1 has two types of "altref": ALTREF_FRAME and ALTREF2_FRAME.

Re: raster scan: it seems that "raster order" is used in the main body of the spec.
