I’d like to share the spec of Flussonic transcoding server:
Dell R720 server with
CPU 2x E5-2660 v2 (2x10 core)
GPU 2x Quadro P4000 cards.
All channels are 720x576 at 25fps
The system is stable with 80 channels GPU transcoded from MPEG2 (5-6 Mbit/s each) to HEVC (around 1.3 Mbit/s).
40 channels are on one GPU card and 40 on another.
System load is around 30-40 and CPU idle is around 60% with periodic drops
to 40% idle.
RAM usage is below 20GB
Each GPU can actually handle around 55 to 60 channels, but the CPU simply can’t handle it (too old).
And what hardware do you use for transcoding?
