Hi all, I just noticed that the MSE specification got subdivided into 5 specifications. Since MSE has to deal with segmenting media files into smaller pieces that can then be adaptively streamed and recombined via HTTP streaming, a lot of metadata is being used there, too. Thus, there is some overlap between what we're trying to do and what is specified there. The main spec is this: http://www.w3.org/TR/media-source/ It explicitly talks about Track ID, kind, language, but not label. The next spec is a registry for byte stream formats: http://www.w3.org/2013/12/byte-stream-format-registry/ The others are the byte stream format specs: WebM Byte Stream format: http://www.w3.org/2013/12/byte-stream-format-registry/webm-byte-stream-format.html ISO BMFF Byte Stream format: http://www.w3.org/2013/12/byte-stream-format-registry/isobmff-byte-stream-format.html MPEG-2 TS Byte Stream format: http://www.w3.org/2013/12/byte-stream-format-registry/mp2t-byte-stream-format.html They aren't currently specifying how to retrieve Track ID, kind and language from the files that they are delivering, but it's good to keep an eye on these. Cheers, Silvia.
