av_dynamic_hdr_plus_from_t35() returned AVERROR(ENOMEM) when passed a NULL AVDynamicHDRPlus. A NULL output struct is invalid API usage by the caller, not an allocation failure, and nothing is allocated on that path. av_dynamic_hdr_smpte2094_app5_from_t35() already returns AVERROR(EINVAL) for the same condition; make the two parsers agree. The documentation for AVDynamicHDRPlus.application_version said the value shall be set to 0, which contradicts both sides of the implementation: av_dynamic_hdr_plus_to_t35() ignores the field and always writes 1, the value CTA-861-H specifies for the HDR10+ payload, and av_dynamic_hdr_plus_from_t35() sets the field from the parsed payload rather than validating it against 0. No FFmpeg code assigns this field, so document the contract the implementation provides. Signed-off-by: marcos ashton <marcosashiglesias@gmail.com>
