@JB - So what prevents to push this two line fix to the main source tree ?

An official spec, I guess

assigned to @robUx4 and unassigned @typx

It's in the official specs: https://github.com/Matroska-Org/matroska-specification/blob/master/codec_specs.md and https://github.com/Matroska-Org/matroska-specification/blob/master/subtitles.md !!!

ping

Simply mapping the codec ID is not enough. We need to map the codec private data internally to something that looks more like a DVB frame to the decoder.

Any updates here?

No.
