Update imscJS prod dependency

[mlasak]

The imscJS dependency should be updated to 1.1.1

• check why simply updating the module will lead tests to fail
• fix the issues in usage of the module to be able to update

@mlasak There is no IMSC 1.1.1 - the currently active IMSC versions are 1.0.1, 1.1 and 1.2. Each in turn adds features to the previous, but there are no breaking changes in the sense that an IMSC 1.2 processor can play back an IMSC 1.0.1 document; however a document using features only defined in IMSC 1.2 would need an IMSC 1.2 processor, of course.

I agree that we should make sure that the version of imsc.js that is used in dash.js is updated to the latest. CC @palemieux also.

Hi @nigelmegitt, yes thanks and sorry for not being specific enough. I was referring to the node.js dependency version, not the W3C recommendation. I'll update the title to use imscJS to make this more clear.

Hello, we are keen to update the version of imsc.js that is bundled with dash.js as there are a number of bug fixes and performance improvements that we feel are important.

I noted a task "check why simply updating the module will lead tests to fail". I updated the version myself in a local branch and found that all tests are passing successfully. @mlasak could you describe the issue you were seeing yourself? Based on the creation date of this ticket, I note that you have tested against dash.js v3.1.2 or lower. Perhaps these issues have been resolved since major update to 4.x.x?

@mlasak can you describe the "issues in usage of the module to be able to update"? Were these dash.js integration issues or imsc.js compatibility issues with your own content?

One of our partners has confirmed that they are successfully using the latest version of imsc.js with their live dash stream outside of dash.js and we're keen to bring parity with the bundled version here.

Any thoughts on the best way forward would be appreciated.

Latest imscJS release is 1.1.3 currently.
