Summary

Support for https://github.com/madebyollin/taehv/blob/main/safetensors/taeh3.safetensors

Related Issue / Discussion

Additional Information

Encoding images tested and works, video decoding works but uses too much memory (OOM on ROCm backend for 2s videos, even with --vae-conv-direct, I think sequential decoding should be implemented to lower the memory requirements. Works on CPU backend for longer videos, but not as quick)

I have managed to get the parallel version of taehv decoding working, but the graph size is scaling with the number of frames... I will try to make it work cleanly without exploding graph size and open another PR.

Edit: maybe the larger graph size isn't that bad after all.
