[FFmpeg-user] Compile ffmpeg and error on nvcc

[Michele Salerno]

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...

  CUDA Device Query (Runtime API) version (CUDART static linking)

Detected 1 CUDA Capable device(s)

Device 0: "GeForce GTX 660"
   CUDA Driver Version / Runtime Version          11.2 / 11.2
   CUDA Capability Major/Minor version number:    3.0
   Total amount of global memory:                 2000 MBytes 
(2096693248 bytes)

   Memory Clock rate:                             3004 Mhz

i see in file configure this

if enabled cuda_nvcc; then
     nvcc_default="nvcc"
     nvccflags_default="-gencode arch=compute_30,code=sm_30 -O2"
else
     nvcc_default="clang"
     nvccflags_default="--cuda-gpu-arch=sm_30 -O2"
     NVCC_C=""

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
