I have a VCD with mpg files that the native Videos app does not play the video, it just shows blank screen, and no audio either. VLC player plays the same files successfully. I do see gstreamer1.0-plugins-* are installed with version 1.14.5, as these were listed as a solution in another similar question about native Video app not able to play video files that VLC player plays successfully.
Please let me know if further clarification/information on this topic is needed from my side that could help addressing this issue at hand.
