Summary0002999: mlt/kdenlive deadlock
DescriptionLatest mlt and kdenlive from git, ffmpeg 7:1.0.1-dmo1 from deb-multimedia.org.

Playing timeline with few video clips, some with proxy, still photos, mp3 and wav audio track (mp3 seems to have syncing issues so I was trying to switch to wav). Kdenlive deadlocked a few times during past 30 minutes but don't know how to repeat this.

It also seems that mlt/kdenlive are using more memory than before which results in swapping (and makes the deadlock easier to hit). Rendering three minute timeline
with minimal effects:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
10016 mcfrisk 20 0 2164m 1.2g 1884 S 115.3 63.2 18:34.91 melt

Kdenlive opened with same project without any timeline preview:

  PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
10166 mcfrisk 20 0 559m 284m 17m S 1.3 14.2 0:55.19 kdenlive
