this may be due to the fact that your trying to send both output files to 
stdout ( - ).

if you specify an output file for each, it should work just fine (as it did for 
me when i just tested it)


here is the complete uncut console output from my test using one of my own 
video streams as input...

i added -vtag hvc1 so h265 files will preview on a mac in finder/quicklook and 
i also added -t 00:00:08.000 to only record a small clip for testing purposes
