Hi Marius,
I have no idea if it is the "-strict experimental" option or if it is something else...
Could also be my ancient computer. It runs WinXP, the CPU is an old Intel Coppermine without SSE2 support.
It happens with ffmpeg point releases 2.86 and 3.00 (and higher). Of course the Win32 static versions from Zeranoe. The versions up to 3.00 still support WinXP, higher versions need to be patched. And these versions run perfectly on my machine under AVStoDVD, DVDStyler and some other applications.
When I try to convert a small FLV clip it works nicely using the ffmpeg version which ships with dmMediaConverter 1.80. The following command line is used:

When I replace ffmpeg.exe and ffprobe.exe with one of the newer versions, the job fails without any error message in the output window. The output window looks like this:

I have not tested this using a different computer, mainly because I have switched to Sherpya's ffmpeg builds which allow me to use libfdk_aac.
