Hi there,

I’ve got an question regarding conversation from multiple PNGs into a VP9 movie. Currently we are doing this job with our CPU and this is quite slow… about 2.5fps in average and we have multiple movies to create every hour.
My idea was to accelerate it via an dedicated graphic card which can be installed into our server to speed this things up.

Which graphic card can handle this work for me and which parameters or additional software pieces are required? (Vendor, Model)

My current system is an Ubuntu 22.04 LTS 64bit and this is our current command line which converts the PNGs to an VP9:
ffmpeg -y -r 4.86 -pattern_type glob -i $DIR'/*.png' -c:v libvpx-vp9 -b:v 0 -crf 30 -row-mt 1 -pix_fmt yuva420p -threads 8 -slices 16 -f webm $WORKINGDIR'/'$DIR'.webm.tmp'
(Codeline is snipped from a bash script which fills the variables with the necessary values)

Thanks for advance for any help 😊

Mit freundlichem Gruß
