I compile ffmpeg for use cuda.
My gpu is Geforce GTX 660 and i have installed driver and cuda from site
nvidia (no repositoty of debian).
# /usr/local/cuda/samples/bin/x86_64/linux/release/deviceQuery Starting...

i see in file configure this

else

ERROR: failed checking for nvcc.
if change nvccflags_default="-gencode arch=compute_30,code=sm_30 -O2" to
nvccflags_default="-gencode arch=compute_35,code=sm_35 -O2" its fine
compile.
Because with compute 30 i have error?
and i have error for conversione files
