I have this problem:
Before installing QL Video the HEVC files would play well when I click on the space bar on finder but the files had no thumbnail. After installing QL Video the files have a thumbnail (although it takes sometime to load) but they won't play when I click the space bar in finder. They just open a still image like this I'm attaching. I'm running High Sierra (10.13.6). The files I have problems were recorded with the Mavic Pro 2 . Can someone please help fix this? Thanks!
Certain video files only show a static image preview. For these videos the diagnostic log includes the following error:
For example the BigBuckBunny_2000hevc.mp4 (H.265 4K) file from the x265.com samples produces this error, but the BigBuckBunny_2000h264.mp4 (H.264 4K) file plays back fine. The Tractor_500kbps_x265.mp4 (H.265 HD) also plays back fine. So it's not only about the codec, but some property of the compression or container that invokes the error.
Renaming the file from
.mp4
to.m4v
as described in the Limitations section does not help.ffmpeg
does not reveal any significant codec differences (see failing video on right), other than frame rate and dimensions. Note however that thesample_ascpect_ratio
anddisplay_aspect_ratio
fields seem to be messed up:0:1
