Streaming adaption based on clean random access (cra) pictures

2:

• A method of processing video data, the method comprising:
• receiving, at a video decoding device, a message comprising an external indication from a source device external to the video decoding device;
• receiving, at the video decoding device, a video bitstream, wherein the video bitstream comprises compressed video data and wherein the video bitstream is received separately from the message comprising the external indication;
• setting a value of a HandleCraAsBla flag to a value specified by the message, the HandleCraAsBla flag being indicative of whether a clean random access (CRA) picture is to be processed as a broken link access (BLA) picture;
• processing the CRA picture as a BLA picture based on the value of the HandleCraAsBla flag;
• and
• based on the value of the HandleCraAsBla flag, setting a value of a second flag, the second flag being indicative of whether at least one picture decoded prior to decoding of the CRA picture is to be output.

6:

• A video decoding device, comprising:
• memory configured to store video data;
• and
• a processor in communication with the memory, the processor configured to:
• receive, at the video decoding device, a message comprising an external indication from a source device external to the video decoding device;
• receive, at the video decoding device, a video bitstream, wherein the video bitstream comprises compressed video data and wherein the video bitstream is received separately from the message comprising the external indication;
• set a value of a HandleCraAsBla flag to a value specified by the message, the HandleCraAsBla flag being indicative of whether a clean random access (CRA) picture is to be processed as a broken link access (BLA) picture;
• process the CRA picture as a BLA picture based on the value of the HandleCraAsBla flag;
• and
• based on the value of the HandleCraAsBla flag, set a value of a second flag, the second flag being indicative of whether at least one picture decoded prior to decoding of the CRA picture is to be output.

12:

• A video decoding device, comprising:
• storage means for storing video data;
• means for receiving a message comprising an external indication from a source device external to the video decoding device;
• means for receiving a video bitstream, wherein the video bitstream comprises compressed video data and wherein the video bitstream is received separately from the message comprising the external indication;
• means for setting a value of a HandleCraAsBla flag to a value specified by the message, the HandleCraAsBla flag being indicative of whether a clean random access (CRA) picture is to be processed as a broken link access (BLA) picture;
• means for processing the CRA picture as a BLA picture based on the value of the HandleCraAsBla flag;
• and
• means for, based on the value of the HandleCraAsBla flag, setting a value of a second flag, the second flag being indicative of whether at least one picture decoded prior to decoding of the CRA picture is to be output.

16:

• A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, cause one or more processors of a video decoding device to:
• receive, at the video decoding device, a message comprising an external indication from a source device external to the video decoding device;
• receive, at the video decoding device, a video bitstream, wherein the video bitstream comprises compressed video data and wherein the video bitstream is received separately from the message comprising the external indication;
• set a value of a HandleCraAsBla flag to a value specified by the message, the HandleCraAsBla flag being indicative of whether a clean random access (CRA) picture is to be processed as a broken link access (BLA) picture;
• process the CRA picture as a BLA picture based on the value of the HandleCraAsBla flag;
• and
• based on the value of the HandleCraAsBla flag, set a value of a second flag, the second flag being indicative of whether at least one picture decoded prior to decoding of the CRA picture is to be output.
