 Summary of the bug:

 I'm using the tee option to use the same encoding options for different
 outputs. I need to have two SmoothStreaming outputs, but for some reason I

 I'm using cuda from nvidia.
 How to reproduce:
 ffmpeg -nostdin -loglevel verbose -hwaccel_device 0 -hwaccel cuvid -c:v
 h264_cuvid -y -re -i
 -f tee -map i:0x2b -c:a libfdk_aac -ac 2 -bsf:a aac_adtstoasc -b:a: 64k
 -map 0:v -filter:v:0 scale_npp=w=1920:h=1080 -c:v:0 h264_nvenc -preset
 llhq -bf 2 -g 50 -keyint_min 50 -forced-idr 1 -aud 1 -strict_gop 1 -b:v:0
 2000k -maxrate:0 2160k -bufsize:0 5000k -bsf:v h264_mp4toannexb -map 0:v
 -filter:v:1 scale_npp=w=1920:h=1080 -c:v:1 h264_nvenc -preset llhq -bf 2
 -g 50 -keyint_min 50 -forced-idr 1 -aud 1 -strict_gop 1 -b:v:1 2500k
 -maxrate:1 2700k -bufsize:1 6250k -bsf:v h264_mp4toannexb -metadata:s:a:0

 I'm having as error, but I don't know if it has any sense:
 av_interleaved_write_frame(): Operation not permitted
