Bug ID: 364833
Summary: Crash when adding .wtv (Windows Media Center) clip.
Product: kdenlive
Version: 16.04.0
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: grave
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: bobs_spa...@cox.net
Attempting to add a video clip from Windows Media Center (.wtv) causes a crash.
I've tested with two different files - a 1 hour and a 1 minute file. Both files
play OK in both FFplay and melt. They also load instantly and play fine in
kdenlive 0.9.6.
The following results are for Kdenlive version 16.07.70 (not a choice in above
dropdown).
1 minute file: Causes an immediate crash. Dump shown below.
1 hour file: Causes the screen to go gray, with some pretty scary noises like
I've never heard coming from the hard drive. It's a loud continuous vibration
at roughly 20 Hz. Even after I close the greyed-out kdenlive window, the
kdenlive and FFplay tasks continue to run and the hard drive noise continues.
Killing the FFplay task also kills the kdenlive task and stops the hard drive
noise.
In kdenlive 15.12.3, loading these files fails for a different (?) reason –
they create many (infinite?) clips in the project bin with repeated "Multi
Stream Clip" dialogs, taking about 1 minute to load each iteration with lots of
grey-screen time in between.
Reproducible: Always
Steps to Reproduce:
1. Load a .wfv file created by Windows Media Player. Sample file available at
https://dl.dropboxusercontent.com/u/52261998/kdenlive_crash_1.wtv.
2.
3.
Actual Results:
Crash.
Expected Results:
Not crash.
