 Summary of the bug:
 When the command is executed, memory consumption increases linearly and in
 about 600 seconds video, the memory usage of the 64 GB Windows is nearly
 100%.
 When checked in Task Manager, the ffmpeg process in the Process tab does
 not have a large memory consumption, but the memory consumption in the
 Performance tab is 100%.

 How to reproduce:
 {{{
 % ffmpeg -f lavfi -i testsrc2=s=1920x1080:r=30000/1001:d=600
 -filter_complex
 split,signature=nb_inputs=2:detectmode=full:format=xml:filename=test%d.xml
 -f null -
 ffmpeg version N-119864-gf531c91170-20250610 : btbn
 built on ... Windows 11
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
