Pitivi (master flatpak) freeze when editing
@hub
Submitted by Hubert Figuière Assigned to Alex Băluț @aleb
Description
When I do edit, ie split a clip when I'm doing the playback, Pitvi (flatpak, master, up to date) freezes. Here is the collected stack trace. I haven't figured out the exact circumstance, but I only have one project I'm trying to finish to edit.
Videos are all from the same source, ie an Android phone camera in 1080p30
(FWIW it happened 6 times last night)
Program received signal SIGINT, Interrupt.
