Interesting! Would we need to use transpose ffmpeg filter? Need to measure performance impact, and there seem to be no CUDA version, as is the case with scale.

for software surface we should use transpose and for nvidia transpose_npp. I am modifying install_ffmpeg.sh to include support for this.
Still need to nail down for 180 degree rotation do we need to apply transpose_npp twice or we get mirrored image..

Got it. From the docs, mirroring is controlled by _flip suffix of dir parameter.
