Fields¶

Access |
Description |
|---|---|---|---|
cnt_dropped_flag |
r/w |
specifies the skipping of one or more values of n_frames using the counting method specified by counting_type. |
|
counting_type |
r/w |
specifies the method of dropping values of the n_frames syntax element as specified in AV1 Spec 6.1.1. counting_type should be the same for all pictures in the coded video sequence. |
|
discontinuity_flag |
r/w |
equal to 0 indicates that the difference between the current value of clockTimestamp and the value of clockTimestamp computed from the previous set of timestamp syntax elements in output order can be interpreted as the time difference between the times of origin or capture of the associated frames or fields. discontinuity_flag equal to 1 indicates that the difference between the current value of clockTimestamp and the value of clockTimestamp computed from the previous set of clock timestamp syntax elements in output order should not be interpreted as the time difference between the times of origin or capture of the associated frames or fields. |
|
full_timestamp_flag |
r/w |
equal to 1 indicates that the the seconds_value, minutes_value, hours_value syntax elements will be present. full_timestamp_flag equal to 0 indicates that there are flags to control the presence of these syntax elements. |
|
hours_flag |
r/w |
equal to 1 specifies that hours_value is present when full_timestamp_flag is equal to 0 and seconds_flag is equal to 1 and minutes_flag is equal to 1. |
|
hours_value |
r/w |
is used to compute clockTimestamp and shall be in the range of 0 to 23, inclusive. When hours_value is not present, its value is inferred to be equal to the value of hours_value for the previous set of clock timestamp syntax elements in decoding order, and it is required that such a previous hours_value shall have been present. |
|
minutes_flag |
r/w |
equal to 1 specifies that minutes_value and hours_flag are present when full_timestamp_flag is equal to 0 and seconds_flag is equal to 1. minutes_flag equal to 0 specifies that minutes_value and hours_flag are not present. |
|
minutes_value |
r/w |
specifies the value of mm used to compute clockTimestamp and shall be in the range of 0 to 59, inclusive. When minutes_value is not present, its value is inferred to be equal to the value of minutes_value for the previous set of clock timestamp syntax elements in decoding order, and it is required that such a previous minutes_value shall have been present. |
|
n_frames |
r/w |
is used to compute clockTimestamp. When timing_info_present_flag is equal to 1, n_frames shall be less than maxFps, where maxFps is specified by maxFps = ceil( time_scale / ( 2 * num_units_in_display_tick ) ). |
|
seconds_flag |
r/w |
equal to 1 specifies that seconds_value and minutes_flag are present when full_timestamp_flag is equal to 0. seconds_flag equal to 0 specifies that seconds_value and minutes_flag are not present. |
|
seconds_value |
r/w |
is used to compute clockTimestamp and shall be in the range of 0 to 59. When seconds_value is not present, its value is inferred to be equal to the value of seconds_value for the previous set of clock timestamp syntax elements in decoding order, and it is required that such a previous seconds_value shall have been present. |
|
time_offset_length |
r/w |
greater than 0 specifies the length in bits of the time_offset_value syntax element. time_offset_length equal to 0 specifies that the time_offset_value syntax element is not present. time_offset_length should be the same for all pictures in the coded video sequence. |
|
time_offset_value |
r/w |
is used to compute clockTimestamp. The number of bits used to represent time_offset_value is equal to time_offset_length. When time_offset_value is not present, its value is inferred to be equal to 0. |
