(as e.g mc_chroma is using the sps to determine picture properties, like pic_width_in_luma_samples and pic_height_in_luma_samples, I *think* this is more correct. This PR is for discussion. (See strukturag#345.) It makes the failures go away, but that does not mean it's correct :) The following poc will be stop failing if (only) this patch is applied: - poc2 strukturag#336 - CVE-2022-43238 - poc4 strukturag#338 - CVE-2022-43241 - poc6-1, poc6-2 strukturag#340 - CVE-2022-43242 - poc7-1, poc7-2 strukturag#341 - CVE-2022-43239 - poc8-1 strukturag#342 - CVE-2022-43244 - poc9-3 strukturag#343 - CVE-2022-43236 - poc10-2, poc10-3 strukturag#344 - CVE-2022-43237 - poc16 strukturag#350 - poc19 strukturag#353 The following are still failing if only this patch is applied, but they stop failing if strukturag#365 is applied as well, but will still fail with ONLY strukturag#365 applied (IOW, both are needed) - poc1 strukturag#335 - CVE-2022-43240 - poc3 strukturag#337 - CVE-2022-43235 - poc5 strukturag#339 - CVE-2022-43423 - poc9-1,poc9-2, poc9-4 strukturag#343 - CVE-2022-43236 - poc14 strukturag#348 - CVE-2022-43253 - poc15 strukturag#349 - CVE-2022-43248 - poc17-1, poc17-2 strukturag#351 - poc18 strukturag#352 - CVE-2022-43245
