Files are organized in directories, one for each event. Files inside those directories are organized with the following naming convention:
eventX_playback_statistics_Y.csv
where X is the event number or identification and Y is the file number breakdown for each event to accommodate GitHub's limitation of 100 MB file size.
Each file contains the following columns:
| Category | Parameter | Description |
|---|---|---|
| session | session | Randomly generated number associated with each player session |
| seq | Sequential number of an event within a session | |
| client | device_type | Device type. Possible values: “desktop”, “mobile”, “tablet”, “tv”, “other” |
| device_os | OS type. Possible values: “windows”, “osx”, “linux”, “android”, “ios”, ”webos”, ”other” | |
| browser | Browser type. Possible values: “chrome”, “firefox”, “safari”, “edge”, “ie”, “opera”, “other” | |
| player | Player type. Possible values: “app” – dedicated application, “web” – JS / browser-based player | |
| player_width | Player window width [pixels] | |
| player_height | Player window height [pixels] | |
| rendition | rendition_indicated_bps | Rendition bitrate [bps]. Sum of audio and video bitrates. |
| rendition_width | Video width as encoded [pixels] | |
| rendition_height | Video height as encoded [pixels] | |
| rendition_framerate | Video framerate [fps] | |
| video_codec | Video codec type. Possible values: “h264”, “hevc”, “av1” | |
| video_codec_profile | Video codec profile. Possible values: “baseline”, “main”, “high” | |
| format | Streaming format. Possible values: “hls_v3”, “hls_v7”, “dash” | |
| segment_duration | Segment duration [seconds] | |
| playback | video_seconds_viewed | Seconds of media content played in the period between the last two player events |
| forward_buffer_seconds | The number of seconds of media content buffered but not yet played | |
| rebuffering_seconds | The total number of seconds the player was “buffering” in the period between the last two player events | |
| rebuffering_count | The number of times the player was “buffering” in the period between the last two player events | |
| media_bytes_transferred | The total number of bytes transferred since the start of the session | |
| network | measured_bps | Network bandwidth [bps] estimated based on size and delivery time of the last segment downloaded |
