[SOLVED] Security ip cams mosaic with vaapi

john i

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!

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

Ok,
the following code is 3x3 mosaic vaapi ha with ffmpeg

Thank u all!
