Description Sebastian Dröge (slomo) 2010-05-01 12:48:39 UTC 
matroskademux should support seeking in push mode and if no cues are inside the file.

Seeking without cues could be implemented by a binary search as in oggdemux and an automatically generated index during playback.

    matroskademux: implement push mode seeking
Comment 2 Mark Nauwelaerts 2010-06-17 06:43:03 UTC 
For v2 matroska files (that at least record keyframe info), presumably something similar to flvdemux or oggdemux could be done (if no cues).
Comment 3 Sebastian Dröge (slomo) 2010-06-17 07:00:17 UTC 
Hm, actually I already started to implement this similar to oggdemux. I hope you didn't start too already, Mark? :)
Comment 4 Mark Nauwelaerts 2010-06-17 07:02:57 UTC 
Not yet.
Comment 5 Sebastian Dröge (slomo) 2010-06-17 07:07:29 UTC 
Ok, do you want to do this then or shall I? I don't have that many changes yet
Comment 6 Mark Nauwelaerts 2010-07-22 10:21:49 UTC 
The following then takes care of seek without cue:

    matroskademux: pull mode non-cue seeking
    
    That is, in files that have no index (Cue), perform seek by scanning for
    nearest cluster with timecode before requested position.  Scanning is done
    as a combination of interpolation and sequential scan.
    
    Fixes #617368.
