Questionnaire-based survey investigating the influence of various system-related factors on overall experience and quality perception of audiovisual calls on smartphones (dataset will be made available pending paper acceptance).

This dataset contains the results of two surveys: Survey 1 -  272 participants, conducted in February 2020;  Survey 2 - 249 participants, conducted in October 2021. Data was collected on user opinions regarding the influence of various factors related to media quality, functional support of the service, usability, service design, and resource consumption. The focus was on audiovisual calls established in a leisure context, as opposed to business related calls/meetings.

OTT video streaming dataset containing user interactions (download here)

The dataset contains network traffic statistics and ground-truth application-layer data corresponding to 7424 video sessions from the global OTT video streaming provider. Data was collected over a four-month period, from December 2020 to March 2021. In total, 2030 videos had no user interactions executed during playback, 1749 videos were paused once during playback, 1808 videos were seeked forward at one point during playback, and 1837 videos were terminated before the video ended.

CGD: A Cloud Gaming Dataset with Gameplay Video and Network Recordings (download here)

CGD, a dataset consisting of 600 game streaming sessions corresponding to 10 games of different genres being played and streamed using the following encoding parameters: bitrate (5, 10, 20 Mbps), resolution (720p, 1080p), and frame rate (30, 60 fps). For every combination repeated five times for each game, the dataset includes: 1) gameplay video recordings, 2) network traffic traces, 3) user input logs (mouse and keyboard), and 4) streaming performance logs.

FPV dataset - subjective user scores of QoE, graphics quality, fluidity, and willingness to continue using the system (download here)

We have performed a subjective study on using the Orqa FPV.SkyDive drone flight simulator with FPV goggles gathering over 250 responses on various subjective QoE metrics from 14 participants. The dataset is analyzed and described in the corresponding paper.

YouTube QoE/KPI classification with user interactions - network traffic features annotated with MOS/KPIs (request access here)

Six datasets were collected during the last months of 2019, and contain sessions with none, or one manually triggered user interaction (e.g., pause, seek, abandon, playback speed), with one dataset containing a pair, or a combination of said interactions. Each dataset contains YouTube video streaming sessions that were collected on an Android smartphone, and native YouTube application. A total of 17 machine learning-based models for per-video KPI classification were trained on various combinations of those datasets. A detailed list of features, selected features per model and feature importances are provided here.

YouTube per-video and per-second QoE/KPI classification (request access here)

Two datasets collected in 2019 corresponding to the streaming of 400 YouTube videos on (1) Android and (2) iOS platform. Both datasets include per-video network traffic features, as specified in the corresponding publication, and MOS/KPI labels. Moreover, the Android dataset is available in the format appropriate for real-time (per-second) KPI classification, where 1s intervals are denoted with a set of network traffic features and labelled with KPIs.

YouTube QoE/KPI classification with user interactions - network traffic features annotated with MOS/KPIs (request access here)

Two datasets involving YouTube video streaming sessions to an Android smartphone were collected during Feb. and Mar. of 2019. All traffic was transmitted using the QUIC protocol. Dataset D1 was recorded by streaming 10 different YouTube playlists (each with 10 videos) without any user interactions invoked. Dataset D2 was recorded by streaming one playlist consisting of 8 videos, and included the previously described user interactions, manually invoked during playback. Each dataset is a CSV file used to train machine learning-based models. The file contains all derived features (on a per video level) and the following target labels: longest resolution (two classes); initial delay (two classes), average video bitrate (two and three classes). The lab set up and list of features selected for machine learning model training are provided here.

YouTube per-video QoE/KPI classification (request access here)

We have collected network- and application-level data from 394 YouTube video streaming sessions on Android device connected to a WiFi network in order to train machine learning models which predict YouTube performance from network traffic features. The dataset is described and analysed in the paper.
