            Bug ID: 792336
           Summary: Regression? video-surveilance camera feed, h264
                    keyframes not identified, splitmuxsink doesn't split
                    due to infinite GOP
    Classification: Platform
           Product: GStreamer
           Version: 1.12.3
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: cJ-gnome at zougloub.eu
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

This was working prior to a gstreamer upgrade (prior: 1.8.3 or 1.10.4, current:
1.12.3).

Running the pipeline:
rtspsrc ! rtph264depay ! h264parse ! identity silent=false ! splitmuxsink
name=sink max-size-time=10000000000 location=video%03d.mp4

Now, splitmuxsink doesn't split.

Using ffmpeg to capture the RTSP feed to mp4 without transcoding, then
processing the mp4 with gstreamer doesn't cause issues.
