That does not work as expected anyways because mp4 defaults to aac per
libavformat, and aac is considered experimental per libavcodec. Running
that gives me:
[aac @ 0x7f44a8371dc0] The encoder 'aac' is experimental but experimental
codecs are not enabled, add '-strict -2' if you want to use it.
Now, MLT will automatically set strict=experimental if you add acodec=aac,
or you can supply strict=experimental.
I am not using the build script, but I just updated to today's FFmpeg git,
and I am unable to reproduce the crash. Did you run the source-me script or
the melt wrapper? Maybe you are running a version of melt
some builds I happen to have on my laptop build date:
