Comment:

 it says now to lower threads but it still fails. It does not try to lower
 the ammount of threads.
  Why cannot that be automcatic???


 {{{
 [h264 @ 000002ab2312dcc0] Try lowering the amount of threads. Using 4
 right now.

 }}}

 So now:


 {{{
 [h264 @ 00000244c19223c0]
 decoder->cvdl->cuvidCreateDecoder(&decoder->decoder, params) failed ->
 CUDA_ERROR_INVALID_VALUE: invalid argument
 [h264 @ 00000244c19223c0] Using more than 32 (34) decode surfaces might
 cause nvdec to fail.
 [h264 @ 00000244c19223c0] Try lowering the amount of threads. Using 5
 right now.
 [h264 @ 00000244c19223c0] Failed setup for format cuda: hwaccel
 initialisation returned error.
