Fill the 120-byte SceVideodec2AvcPictureInfo for a single owned H.264 picture queried with thisSize 0x78: SPS fields, VUI, pic_struct from the picture-timing SEI and per-unit presence flags, parsed per ITU-T H.264 (08/2021) from the access unit that produced the picture. Layout from SharpProspero Videodec2.cs and shadPS4 videodec2.h. Other accepted sizes, two records and unsupported syntax still throw after the validity clears.
