           Summary: [ffdec] Check for AV_NOPTS_VALUE in PTS
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: raimo.jarvi at gmail.com

     GNOME version: ---


I've tried decoding some AAC LATM streams with ffdec_aac_latm and the result is
poor. Timestamps in the decoded data are incorrect and after some investigation
it seems that gst-ffmpeg decoder doesn't check for AV_NOPTS_VALUE in PTS. Using
AV_NOPTS_VALUE like a valid PTS causes the incorrect output timestamps, the
attached patch should fix this.
