           Summary: video-chroma: SIGSEGV in chroma_resample() when
                    converting a specific file.
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: mathieu.duponchelle at epitech.eu
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


gst-launch-1.0 uridecodebin uri=file:///home/meh/Videos/prise031.avi !
videoconvert ! video/x-raw, chroma-site=jpeg ! autovideosink

highlights the problem.

It so happens that upsample->v_resample is NULL, which leads to the SIGSEGV.

My instinct would be to add a check there for upsample->v_resample, as I
suppose if it is NULL nothing should be done anyway.

Worthy of note is that with gstreamer 1.2 as shipped in fedora, the SIGSEGV is
triggered by chroma-site=dv and jpeg is fine whereas with master dv is fine and
jpeg SIGSEGVs.

Have a nice day !
