Quelea CI version 2026.0 : opening a schedule with large .mp4 files consumes much system memory

[DeeTigIT]

STEP 1 : make the schedule

2 Large mp4 files are added to a new schedule.

bigfile-1.mp4 1.423.523.388
bigfile-2.mp4 9.891.909.354

BIG-sched.qsch\schedule.xml :

BIG-sched.qsch\resources :

\Mijn gebruikers\MyAccountName\Documenten\QueleaRoot__Testcases\Large vid\bigfile-2.mp4
\Mijn gebruikers\MyAccountName\Documenten\QueleaRoot__Testcases\Large vid\bigfile-1.mp4

After the saving process has finished the Zulu runtime has about 1,7 GB memory in use:

STEP 2 : re-opening the schedule

Restarting Quelea and re-opening this schedule: after the schedule is opened the Zulu runtime has about 21,4 GB (!!) memory in use:

(the memory usage only decreases slowly herafter)

MyAccountName and MyAccountName2 are visually not the same.
Is MyAccountName2 perhaps a 8-char (DOS) representation of the full MyAccountName?

Hmm, I can't seem to recreate this. Just so I know I'm looking in the right place (or not), does the same thing happen whether GStreamer is installed or not - or only with GStreamer installed?

It could be - is this causing an issue or just an oddity? If it's not causing an issue I'm tempted to say it's just an old DOS representtaion, though it's not one I expected to see either.

Only with GStreamer installed.

I've made a recording using the CI windows 2026.0 installer.
In the first part GS is not present: no issue with the JRE memory consumption when opening the BIG schedule.
In the second part I've installed GS 1.26.7: JRE memory usage keeps growing until the schedule items are shown.

In both parts I paused the recording until the schedule items appeared.
Between the parts Quelea was restarted.

It seems that the underlying cause is the same as for #651 : the presence of global video themes. None of these global themes is used as song default however: the song default theme is image-based (no video).

I found:

• When I remove the global vid theme's: the growing of the JRE memory does not occur.
• Each of these global vid themes has a video that exists in the vid-folder.
• None of these global vid themes is used as song default: the song default theme is image-based (no video).
• The greater the number of these global vid themes: the greater the increase in JRE memory after the schedule has opened.

Excellent - thanks for this, I can now recreate it.
