Hello, I try to use Nvidia codecs in live transcoding. The input stream is from an IP camera (Hikvision) and its color format is "*yuvj420p*". My command is:
ffmpeg.exe -y -hwaccel cuda -hwaccel_output_format cuda -rtsp_transport tcp -i "rtsp://admin:Pass1@192.168.1.1" -flags +low_delay -vcodec hevc_nvenc -s 1920x1080 -preset p2 -pix_fmt yuv420p -tune hq -rc vbr -vb 700k -maxrate 800k -minrate 200k -bufsize 800k -g 25 -acodec copy -strict -2 -flags +global_header -f rtsp "rtsp://localhost:8000/stream" but I am faced with this error: Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scale_0' Error reinitializing filters! Failed to inject frame into filter network: Function not implemented Error while processing the decoded data for stream #0:0 Conversion failed! if I remove "-hwaccel_output_format cuda", the transcoding starts, but the decoded stream is sent to system memory. I prefer to keep it in GPU memory to decrease the latency. What should I do to fix this? I would appreciate any help.
