Hey there,
Does anyone know if CC is supported in a standardized form?
From what I gathered, there seems to be support for a text track in the fragments sent over HTTP, but there is no mention of the correct format and usage of the text data,. Is the text track used for closed captioning (by standard, using a TTML or simialr format) or is it a 'free text' track, which can be interpreted by the HDS player at any way?
If CC is not supported by the official standard, are there any players (e.g. OSMF, Strobe) which support it, even by using plaugins?
Thanks.
