Drops non-base NALs when the base-only property is set to TRUE. This modifies the behavior for MVC streams with base-only too: All the non-base units are dropped before they are decoded instead of dropping the non-base frames. The relevant part from the H264 spec is: > Decoders that conform to one or more of the profiles specified in Annex A rather than the profiles specified in Annexes G or H shall ignore (remove from the bitstream and discard) the contents of all NAL units with nal_unit_type equal to 14, 15, or 20. To eliminate side effects from the offending units: - PPS's with a broken seq_parameter_set_id (referring to dropped subset SPS's) are ignored. - The NAL parsing is skipped and their flags are set to GST_VAAPI_DECODER_UNIT_FLAG_SKIP. - Prefix units are not stored in prev_pi. Otherwise, parse_slice() would use them even if they are flagged to be skipped. Subset SPS's and slice extension units are not stored there either. https://bugzilla.gnome.org/show_bug.cgi?id=732266 Signed-off-by: Sreerenj Balachandran <sreerenj.balachandran@intel.com> |
