Description Benoit Touron 2019-08-29 08:31:11 UTC 
SUMMARY
When you adjust the speed of a clip and its name is <some digits>:<some digits>.mp4, the speed effect does not work.
Tested with mp4 and mts clips.

STEPS TO REPRODUCE
1.Create a project
2.Add a clip named 1:2.mp4
3.Put in in the timeline
4.Adjust speed holding CTRL in the timeline
5.Launch preview

6.Rename the clip to tmp.mp4 and do the same test

OBSERVED RESULT
In the preview vindow, you can see only white, and no sound.
When the clip is named tmp.mp4, it works fine.

EXPECTED RESULT
Normal preview (accelerated clip)
