Hi @nigelmegitt, we are using the latest BBC smp-imsc fork for this. However, it's swapped out in Bigscreen player rather than here — so I've reverted the change here to avoid it being in the bundle twice.

LGTM! Left one comment on docs but I'm not going to block merging on that :)

What's thoughts on declaring a more generic "put your IMSC options here" type rather than calling out a few specific ones? My concern is as written this documentation suggests IMSC options mentioned are the only ones supported.

Outcome of some pairing on this — we've tried to create a generic imscJS options object. However, Dash.js uses the default settings as a way of validating the settings. As a result, we opted to create a more comprehensive list of imscJS render options instead. There are a couple of options have been left out (that are not in use) that require further nested objects. If needed in the future, these could be passed via a new customiseSubtitles() function on the media player rather than via updateSettings().

This PR exposes the
bbc/ImscJScustomisation options to the Dash.js settings in a way consistent with other subtitle settings already within Dash.js.bbc/ImscJScustomisation has been already been PR'd back to mainlinesandflow/imscJS#257. However, there hasn't been any indication when this may be merged.The changes here are compatible with those proposed to mainline
sandflow/imscJSshould the PR be merged.These changes are required to allow customisation of subtitles on TV Platforms through Bigscreen Player for an upcoming low-latency trial. As the content is delivered in chunks for low-latency DASH it is would not be possible to use the existing side-chain mechanism in BSP without significant modification.
