Bug ID: 430193
Summary: renderwidget.cpp overriding threadCount for real_time
mlt option
Product: kdenlive
Version: git-master
Platform: unspecified
OS: All
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: j.straight-...@straights.net
Target Milestone: ---
I noticed that no matter what I set for threads, or parallel processing, or
setting real_time= in render options, I could not get the final render to use
all my cores, like I could in timeline previews by setting real_time=-12 in
encoder options.
Let me preface this by saying that I'm no c++ dev. I have zero experience
there.
But I looked at the source and I found out that it was either 1, or 4 threads.
So I changed it to use the KdenliveSettings::encodethreads() instead, and now
mlt uses the proper number of cores/threads I have set in the rendering dialog.
int threadCount = QThread::idealThreadCount();
if (threadCount < 2 || !m_view.parallel_process->isChecked() ||
!m_view.parallel_process->isEnabled()) {
threadCount = 1;
} else {
threadCount = KdenliveSettings::encodethreads();
}
The threadCount = KdenliveSettings::encodethreads(); was what I changed.
