Description Sebastian Dröge (slomo) 2016-08-05 12:26:15 UTC

Problem is that sidx based segments might not be given in the manifest, so seeking on the mpd parser would always give us 0 as the actual position... Which for snap seeks would be the new segment start.

As explained in the comment linked above, the fix is what was reverted in got. It however breaks the unit tests as explained there, which are IMHO just broken by design.

As such I propose to disable these tests until they're fixed or removed. It might make more sense to use validate tests on real streams instead.

    dashdemux: Disable unit test for the time being
    It uses random data streams but dashdemux nowadays actually looks into the
    streams and doesn't like randomness very much. The tests should probably just
    become validate tests on real streams.
