Added by john i over 6 years ago

Hello,

I'm trying to convert the following command/script for running with vaapi hardware acceleration , but i can't!
Is it possible for multiple inputs?

Thank u!

@ #!/bin/bash

ffmpeg -loglevel fatal \

Where is hardware accelerated strings ?
https://trac.ffmpeg.org/wiki/Hardware/VAAPI
also for mosaic reduce frame rate to 15 fps.
keep in mind that mosaic use lot of memory for hardware transcoding

Thank u, but i don't know the syntax of the command !

I can do it with one input stream and with no -filter_complex !

:)

https://github.com/s7sost/cinegrid
this is interesting, but need to be modified to accept live streams.

also
https://github.com/joolzg/mosaic_generator

but cannot compile give strange errors on different OS
