Background and Justification Haptic signals provide an additional layer of entertainment and sensory immersion for the user. Haptic tracks, in separate files, can be combined with audio/video files and played back in sync to provide an overall immersive media experience (audio, visual, tactile) for the user. More recently, haptic tracks embedded in standard file formats such as ISOBMFF (ISO Base Media File Format), enable playback of the haptic signals over one or more actuators, simultaneously with audio and video playback. --=-=-= Content-Type: message/rfc822 Content-Disposition: inline;

Most of the discussions I see about media types relate to NETCONF and YANG. The text below talks of programming languages. I would like that expanded to be clear that it includes YANG, if not all such DDL. The registrations thereof might have been different had multiple suffixes been specified.

Because you are a member of the IETF CELLAR working group organization and = have already granted this application access to your personal account, Circ= leCI can now access IETF CELLAR working group organization resources on you= r behalf.

You can always see the full list of applications that have access to your a= ccount here:

=C2=A0 https://github.com/settings/applications

If you choose to stop using one of those applications, you can revoke its a= ccess at any time.

The haptics track is interesting and something we should definitely=20 support. It seems it would fall under the "control" (32) track type. We do define some "unofficial" MIME types for Matroska: * .mka : Matroska audio `audio/x-matroska` * .mkv : Matroska video `video/x-matroska` * .mk3d : Matroska 3D video `video/x-matroska-3d` I don't know if we should register official ones.

I finally rewrote the parts about timestamp handling: https://github.com/ietf-wg-cellar/matroska-specification/pull/521 Things are now expressed as ticks: Matroska, Segment, Track. Segment and = Track being the same if TrackTimestampScale is left to 1.0. There's a paragraph explaining the rounding that the muxer should use,=20 knowing the correct sampling rate, to write "ticks" that can be=20 interpreted by the reader accurately to match the samples. The example you found was not correct seem to match with the formula I=20 gave for the muxer and the demuxer. It's a bit counter intuitive as the=20 muxer has to estimate the drift that will occur on the Reader math to=20 write the value that may not end up giving the proper tick value. Given the Segment and Track ticks are always(*) the same, the same=20 applies to the ticks stored in `Cluster\Timestamp`. And that's where=20 most of the drift happens, given a Cluster contains only 65535 ticks.=20 I'm not sure existing muxers use that. Otherwise they probably have a=20 slight drift in timestamps. (*) pending=20 https://github.com/ietf-wg-cellar/matroska-specification/pull/437 we may = or may not use the `TrackTimestampScale` again so that the tick to store = is also be the sample number.
