Compute overhead of H.264 encoder is non-negligible for a VM host where I want all my CPU cycles to go to user VMs. Datacenter-class Intel CPUs (Xeon) don't include H.264 encoders in hardware. QuickSync circuitry is generally limited to consumer-grade CPUs. Not to mention MPEG licensing issues.
AV1 eliminates MPEG licensing issues, but encoding in hardware is even more limited. Also, AV1 is great for encode-once use cases (e.g. YouTube) since it's heavily geared towards reducing bandwidth requirements vs. encode speed. It's workable for real-time streaming in the lowest settings, but H.264 is still better overall.
