comment:2 Changed 11 years ago by rickard

The patch "Suggested_fix_for_#1126.patch" adds checks for the following restrictions:

"When a picture is a leading picture, it shall be a RADL or RASL picture."
"When a picture is a trailing picture, it shall not be a RADL or RASL picture."
"When a picture is a leading picture, it shall precede, in decoding order, all trailing pictures that are associated with the same IRAP picture."
"No RASL pictures shall be present in the bitstream that are associated with a BLA picture having nal_unit_type equal to BLA_W_RADL or BLA_N_LP."
"No RASL pictures shall be present in the bitstream that are associated with an IDR picture."
"No RADL pictures shall be present in the bitstream that are associated with a BLA picture having nal_unit_type equal to BLA_N_LP or that are associated with an IDR picture having nal_unit_type equal to IDR_N_LP."
"Any picture that has PicOutputFlag equal to 1 that precedes an IRAP picture in decoding order shall precede the IRAP picture in output order and shall precede any RADL picture associated with the IRAP picture in output order."
"Any RASL picture associated with a CRA or BLA picture shall precede any RADL picture associated with the CRA or BLA picture in output order."
"Any RASL picture associated with a CRA picture shall follow, in output order, any IRAP picture that precedes the CRA picture in decoding order."
