Ok, I think I found the problem. Occurs when moving a keyframe with effect stack slider. Will try to fix tonight or tomorrow.
After a quick test, I realised I was wrong. The problem is that you have a "volume" effect in one of your tracks (line 1867).
Looks like having a "volume" effect on track cancels the clip's volume effect. Have to check that in MLT. It also highlights the fact that we need to find a clearer way to indicate track effects or users will get lost in such cases...
Deleted them, volume is still constant.
However the effect itself is not broken; I've opened an old file which is using it, and there it's working.
Did some testing and it seems like a bug or a limitation of the volume effect. As I said in my previous comment, the issue is related to the "volume" effect you have on the track.
Looks like when there are 2 different volume effects on the same clip, instead of using the output of the first effect for the second effect, MLT uses the original sound for the second effect, so that the first effect is completely useless.
I can reproduce with following:
melt -track attach volume gain=1 myclip.mpg -attach volume gain=0
Here, the audio plays normally, when it should be muted. The track effect is applied after the clip effect and results in a normal 100% audio.
Forwarding issue on the MLT mailing list for Dan...
|Fixed in mlt git commit 5c885c.|
|Thank you, working correctly now!|
