Detailed Description

statistics for rate adaptation

statistics for download monitoring

Field Documentation

download_rate

attribute readonly unsigned long _DASHGroupStatistics::download_rate

download rate of last segment in bits per second, divided by current playback speed

file_size

attribute readonly unsigned long _DASHGroupStatistics::file_size

size of last segment in bytes

speed

attribute readonly double _DASHGroupStatistics::speed

current playback speed

max_available_speed

attribute readonly double _DASHGroupStatistics::max_available_speed

max playback speed based on associated codec runtime statistics

display_width

attribute readonly unsigned long _DASHGroupStatistics::display_width

display width in pixels of object

display_height

attribute readonly unsigned long _DASHGroupStatistics::display_height

display height in pixels of object

active_quality_idx

attribute readonly unsigned long _DASHGroupStatistics::active_quality_idx

index of current quality or last downloaded quality

buffer_min

attribute readonly unsigned long _DASHGroupStatistics::buffer_min

minimum buffer in milliseconds, below witch rebuffer occurs

buffer_max

attribute readonly unsigned long self _DASHGroupStatistics::buffer_max

maximum buffer in milliseconds, algorithm should not fill more than this

buffer

attribute readonly unsigned long self _DASHGroupStatistics::buffer

current buffer in milliseconds

quality_degradation_hint

attribute readonly unsigned long self _DASHGroupStatistics::quality_degradation_hint

degradation hint, 0 means no degradation, 100 means tile completely hidden

total_rate

attribute readonly unsigned long self _DASHGroupStatistics::total_rate

cumulated download rate of all active groups in bytes per seconds - 0 means all files are local

bits_per_sec

attribute readonly unsigned long _DASHGroupStatistics::bits_per_sec

download rate of last segment in bits per second

total_bytes

attribute readonly unsigned long _DASHGroupStatistics::total_bytes

total number of bytes in segment

bytes_done

attribute readonly unsigned long long _DASHGroupStatistics::bytes_done

number of downloaded bytes from segment (starting from first byte)

time_since_start

attribute readonly unsigned longlong _DASHGroupStatistics::time_since_start

number of microseconds elapsed since segment was scheduled for download

buffer_dur

attribute readonly unsigned long _DASHGroupStatistics::buffer_dur

current buffer length in milliseconds

current_seg_dur

attribute readonly unsigned long _DASHGroupStatistics::current_seg_dur

duration of segment being downloaded, in milliseconds - 0 if unknown
