Bug ID: 366570
Summary: Kdenlive git master: crash on invoking render widget
with MLT 6.3.0(git master)
Product: kdenlive
Version: unspecified
Platform: Debian unstable
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: directact...@hushmail.com
Immediate crash and segfault on Kdenlive master with MLT master whenever the
render widget is invoked.
Since commit
http://quickgit.kde.org/?p=kdenlive.git&a=commit&h=9a9346e21eed58d6d58ee9e10ecb3e88f0c39bc3
(Fix crashes when using MLT 6.2.0) and the later 8a4ebe4 requires to build it,
clicking the "render" button on the toolbar or selecting "render" from the menu
instantly crashes kdenlive with a segfault. This is with Movit enabled and
using MLT 6.3.0 from git master, MLT builds from July 5 2016 and August 8 2016
pulls exact same behavior. QT and KF5 are what is in Debian Unstable as of
August 10 2016 and same with what was in Debian Unstable in late July.
I was able to trace the exact offending line in commit 9a9346e to the line
below in mainwindow.cpp :
m_renderWidget->errorMessage(m_compositeAction->currentAction()->data().toInt()
== 1 ? i18n("Rendering using low quality track compositing") : QString());
Reverting that line to the previous
m_renderWidget->errorMessage(m_compositeAction->currentItem() == 1 ?
i18n("Rendering using low quality track compositing") : QString());
will permit kdenlive to build and run without crashing when the renderwidget is
invoked as of today. Last commit was
http://quickgit.kde.org/?p=kdenlive.git&a=commit&h=f8580603474e1765289d29d00e17ca1b3289f215
Reproducible: Always
Steps to Reproduce:
1. Build MLT from git master, build kdenlive from git master and install on
Debian Unstable
2. Start kdenlive
3. click the "render" button in the toolbar or invoke "render" from the project
menu
Actual Results:
Immediate crash and segfault
Expected Results:
Render widget appearing, displaying the options for rendering out the finished
video.
