I created a test .mp3 file with perfect silence on it through Audacity. Importing and playing back into Kdenlive 15.13.0, the silence reads at around -30db, which seems to be the bare minimum level that the indicators will stay... which isn't indicating true silence. Normal operations should be silence not showing on the audio level meter at all. (I'm including the test file for use). Reproducible: Always Tested using Kdenlive 15.13.0.r6959.f4e0fb5-1 on Antergos (Arch) Linux x64, GNOME 3.18.2
Created attachment 96834 [details] Silence example
Noticed that too, so that I also included it independently in bug https://bugs.kde.org/show_bug.cgi?id=358427. However, I also still have some issues with the exact marks, as I miss the common -10dB mark. For me, it seems that "silence" is stuck around -22dB or so.
Yes, there currently is a problem with low audio levels. I tracked the issue to MLT's audiolevel filter that we use and proposed a patch here: https://github.com/mltframework/mlt/pull/95 With the patch, it works perfectly for me.
Good stuff. Will wait for the patch to hopefully be implemented by MLT dev's. Thanks JB!
Just curious, how can we check if/when the MLT crew has implemented this patch?
I will try to remember closing this bug if the patch is committed to MLT, but otherwise you can check the github link in my previous comment where the discussion about the patch is happening. The status of the issue will be changed from "open" to "closed" if it is accepted. Dan Dennedy, maintainer of MLT is usually quite reactive.
Awesome. Thanks for the intel'.
LasT part of this bug was fixed in MLT git master, should work fine now
Confirmed (in Arch). Building and installing mlt-git package, then building and installing kdenlive-git package shows this issue has been resolved. Thanks guys! Marking this bug as fixed.
