Shotcut crashes on start

ver. 18.08.14 (every version I tested crashed)
Windows 10
64 bit

reinstalling doesn’t help
deleting registry entries doesn’t help

In your local appdata folder there’s also a folder with settings and a little SQLite db. Just search for shotcut under c:\users\username\appdata\local and you will find the folder (sorry, I’m currently not on my computer).
Rename this folder and try again.
Also take a look into the taskmanager if another shotcut.exe process is running. Kill all of them. This happens very often to me.
If nothing helps, try to take a look in your eventlog. Past the application error here, probably it could help the developers to troubleshoot…

Thanks, but I can’t find the folder except the file shotcut-log.txt. There are no other processes running and I don’t know where to find the eventlog.

Look for userprofile\AppData\Local\MeltyTech\Shotcut and rename the entire folder; the shotcut-log.txt is one of the files in that folder.

That file may also contain a hint as to why it’s crashing on start.

Posting the log here could help us identify the problem.

To go to the folder just press windows button+R and enter %LOCALAPPDATA%\Meltytech\Shotcut.
To go to the eventviewer presswindows button+R and enter eventvwr. Then take a look in to the application log.

It’s actually easier this way.
app%20data%20directory
If you can’t see the folder read this article: https://help.ableton.com/hc/en-us/articles/209070509-How-to-access-hidden-folders It shows how to unhide folders. Windows hides the AppData folder by default, you just have to unlock/unhide it once.

The AppData folder is used by many different programs, not just Shotcut.

Renaming it doesn’t help

Is that all of it? If so, it seems that the code is getting into the constructor for the Mlt::controller class but is not getting out:

github.com

mltframework/shotcut/blob/master/src/mltcontroller.cpp#L52


static int alignWidth(int width)
{
return (width + 7) / 8 * 8;
}


Controller::Controller()
: m_audioChannels(2)
, m_volume(1.0)
, m_skipJackEvents(0)
{
LOG_DEBUG() << "begin";
m_repo = Mlt::Factory::init();
m_profile.reset(new Mlt::Profile("atsc_1080p_25"));
m_filtersClipboard.reset(new Mlt::Producer(profile(), "color", "black"));
updateAvformatCaching(0);
LOG_DEBUG() << "end";
}


Controller& Controller::singleton(QObject *parent)
{
if (!instance) {

There should be a corresponding message that says: “[Debug ] Mlt::Controller::Controller end”

this is a clue, but unfortunately, it doesn’t help me know what is failing exactly.
