Original commit message from CVS: * gst/matroska/matroska-demux.c: (gst_matroska_demux_add_stream), (gst_matroska_demux_video_caps): * gst/matroska/matroska-ids.c: (gst_matroska_track_init_video_context): * gst/matroska/matroska-ids.h: Try harder to extract the framerate for video tracks correctly and save it directly instead of converting it back and forth a few times. Mostly makes a difference for very small framerates (<1). Fixes #380199.
