gstreamer/gst/matroska/matroska-ids.h
Tim-Philipp Müller 0d3b023699 gst/matroska/: Try harder to extract the framerate for video tracks correctly and save it directly instead of convert... 
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.
