           Summary: [asfdemux] handle negative payload timestamps
    Classification: Desktop
           Product: GStreamer

            Status: UNCONFIRMED

Some files [1] might have payloads with timestamps smaller than the preroll
value. Currently we blindly substract the preroll value from those timestamps,
resulting in pushing out buffers with insanely high timestamps... screwing up
sync downstream.

The following patch makes sure we never end up with wrong timestamps.

[1] Agreed, those files were most likely created by a broken muxer, or captured
in some weird fashion and it should never happen on spec-compliant (sic) asf
files. Better be safe than sorry though.
