** Notice: all internal pipelines have been restricted to 30 minute timeouts, if your CI/CD runs take longer, either use your own runners or read below **
We would remind everyone that the CI/CD services provided by the university Gitlab servers are intended for CI/CD use only (ie. delivering new versions of your software to your production servers, etc).They are not intended for data analysis or -production use, or creating, building and running servers to do heavy data calculation or visualization.
As a general guideline; if your jobs take more than 15 minutes, you might be running something that is better suited for a dedicated system or a virtual server - in this case, please contact the helpdesk for a solution to your needs.

# 2. OVERALL DESCRIPTION
The prototype will be a new platform that enables the capture, mixing, filtering, analysis, recording and streaming of teleimmersive 4D audio-visual data in a real-time, modular and flexible manner so that individual data sources or algorithms can be replaced or evolved in the future. The key features are therefore:
***F1:***Capture* - Scene reconstruction from fixed lab spaces as a 4D-AV data source
***F1:***Generation* - Scene reconstruction from fixed lab spaces as a 4D-AV data source
***F2:***Mixing* - 4D-AV mixing and filtering system, from any number of arbitrary data sources
***F3:***Analysis* - 4D-AV Analysis system to extract and embed higher-level data about a scene
***F4:***Recording* - 4D-AV recording and playback as a generic 4D-AV data source

## 3.1 FUNCTIONAL REQUIREMENTS
### 3.1.1 Capture (F1)
### 3.1.1 Generation (F1)
***3.1.1.1** Capture a 4D-AV scene in real-time from a fixed laboratory with multiple people
***3.1.1.2** Allow 4D scenes to be generated virtually from some scene description and animation
***3.1.1.3** Support the translation of more traditional formats into our 4D-AV representation as a source
### 3.1.2 Mixing (F2)
***3.1.2.1** Merge multiple 4D-AV scenes into a single scene, with no restriction on the origin of the scene
***3.1.2.2** Filter a scene to exclude all but a specified collection of entities
***3.1.2.3** Filter a scene to exclude specific entities
***3.1.2.4** Filter a scene by bounded region
***3.1.2.5** Allow data channels or kinds of data to be filtered from the scene
***3.1.2.6** Allow scene transformations (translation, scaling, rotation) when mixing
***3.1.2.7** Any mixed scene output can also be an input to another mixing operation
### 3.1.3 Analysis (F3)
### 3.1.4 Recording (F4)
### 3.1.5 Streaming (F5)
***3.1.5.1** Support adaptive bitrate streaming of 4D-AV scenes
***3.1.5.2** Allow for channel selection or exclusion from the data stream
***3.1.5.1** Support compressed adaptive bitrate streaming of 4D-AV scenes
***3.1.5.2** Support lossless compression of 4D-AV scenes
***3.1.5.3** Streams can contain non-AV data streams for additional forms of basic or higher-level data
***3.1.5.4** Allow for channel selection or exclusion from the data stream
***3.1.5.5** Stream decoding must function within a web-browser
