Hi,
I am trying to join 11 video files, each 3 minutes in length. I can get
the video rendered correctly, where the audio only lasts 3 minutes from
input 0. But when I add the amix filter, it fills 16Gb of memory in 2
minutes and gets it's process killed.
The full command line and output, before and after adding
;amix=inputs=11:duration=longest
are in this 43Kb text file:

That's a large command for us to have to parse. I recommend omitting
anything that isn't required to reproduce the issue and to provide a minimal
command that still shows the problem. It will increase your chances to receive
answers. Provide a link to any files that are needed so we can try it if it
can't
be reproduced with synthetic inputs (testsrc2 and sine filters for example).
Yes it is large. A good reason I provided it as a separate file. And I
highlighted the only filter I changed.
My first concern: Did I use the amix filter incorrectly?
I was looking for an alternative to trimming and concat. "Can I do it
all in one command and avoid the iframe issue."
Either the answer is no, or I just did it wrong.
Paul's answer indicates no. Thus this approach should be dropped?
Also if I did it incorrectly, then I was looking to understand what part
of the command either leaked or asked for an infinite length file in memory.
