UI elements
Component exposes four UI elements. Three of them are listed under Youtube Source group in UI elements list (Activity, Analysis Cache and Search (Integrated)) and one is placed under Playback Visualization group (Video).
UI element Search (Integrated) is described in Search topic.
UI element Video is described in Video topic.
The rest two are described below.
Analysis cache
Component caches info about all media files that were found during the analysis of recently opened videos. Videos, whose analysis results are already cached, open much faster.
Number of tracks to keep in cache can be configured using component preferences Decoder Maximum number of tracks in analysis cache.
Analysis results become obsolete with time so eventually they cannot be used to open a video. Therefore component controls cache lifetime. It can be adjusted using option Decoder Analysis cache expiration time (what is merely a hack rather than solution, but this is still better than nothing).
Analysis cache can be explored using UI element Youtube Source Analysis Cache and using popup window in menu View Youtube Source Analysis Cache.
This UI consists of tree control containing all tracks stored in the analysis cache. Child nodes of track elements in the tree represent all streams found during the analysis. Streams to display can be filtered using the tree context menu.
Context menu item Properties provides a report containing full list of known properties for the selected stream. These properties are used when selecting stream via media criteria.
Activity
This one is available only as UI element. It visualizes connections currently opened within the component.
Connections made directly by the component are visualized in the most detail. This includes indication of already downloaded data, opened connections (there can be more than one for single file), readers for this file (multiple readers can read single file at the same time) and overall download speed.
Connections made by other data providers (foobar2000, ffmpeg, LAV Filters) have less info or not displayed there at all.
