Video coding using end of sequence network abstraction layer units

An apparatus comprising:

• a memory configured to store video data;
• and
• a processor configured to:
• access an encoded video bitstream comprising multiple layers from the memory, the encoded video bitstream including multiple access units, wherein a first access unit includes an end of sequence network abstraction layer unit, and wherein a second access unit includes an intra random access point picture and is a next subsequent access unit in decoding order following the first access unit;
• derive a reinitialization flag to be a value indicating that decoding is to be reinitialized at the second access unit, wherein the reinitialization flag is derived to be the value based on the second access unit being the next subsequent access unit in decoding order following the end of sequence network abstraction layer unit of the first access unit;
• and
• reinitialize decoding at the second access unit based on the value of the reinitialization flag.

A method of processing video data, the method comprising:

• obtaining a first encoded video bitstream comprising multiple layers, the first encoded video bitstream including multiple access units;
• obtaining a second encoded video bitstream comprising multiple layers, the second encoded video bitstream including multiple access units;
• generating a third encoded video bitstream by combining access units in the first encoded video bitstream with access units in the second encoded video bitstream, and by inserting an end of sequence network abstraction layer unit into a first access unit of the first encoded video bitstream, wherein a second access unit of the second encoded video bitstream includes an intra random access point picture and is a next subsequent access unit in decoding order following the first access unit with the end of sequence network abstraction layer unit;
• and
• transmitting the third encoded video bitstream, wherein the second access unit being the next subsequent access unit in decoding order following the end of sequence network abstraction layer unit of the first access unit causes decoding of the third encoded video bitstream to be reinitialized at the second access unit.
