Hi All! I am trying to make the indoor station display a stream from a non HIK camera. I have set up an RTSP transcoding proxy which uses ffmpeg behind the scenes to transcode the stream on the fly. I publish the stream under /streaming/channels/101 etc. After adding the stream via iVMS-4200 I can open it and see it starting (and continue) to stream on the proxy but the feed is black on the indoor station. It works fine in VLC.

Code:
ffmpeg -i rtsp:/other_cam -c:v libx264 -pix_fmt yuv420p -s 1280x720 -max_muxing_queue_size 1024 -analyzeduration 0 -probesize 50000 -an -f rtsp rtsp:/localhost:$RTSP_PORT/streaming/channels/101
I was wondering if anyone knew what exact format of the stream does the indoor station take. I've seen an old PDF from HIK saying h264 & 1280x720 max.

Any suggestions much appreciated.
