Runtime problem with `qtdemux` for mingw build only

I have a video file (no audio) which plays nicely in

  • VLC
  • Windows Media Player on Windows 10
  • Whatever application plays videos by default in Windows 10

The video is here: screencap.mp4

I have analyzed the video with ffprobe (in many ways) and I cannot find any problems with it.

The problem is: qtdemux doesn't play nicely with the video; and so I cannot use GES with the video (which is my ultimate goal).

The problem exists in the following versions.

  • gstreamer 1.14.4-mingw
  • gstreamer 1.16.0-mingw

The problem does not exist in the following versions.

  • gstreamer 1.16.0-msvc
  • gstreamer master (1.16.1) on fedora 30 (built using gst-build)

The problem is easily reproduced using gst-launch commands for the affected versions.

$ gst-launch-1.0 filesrc location=screencap.mp4 ! decodebin ! playsink
