I have a number of observations from the above:
1) The EMS does not support OGG Theora. Most HLS players, as I understand, don’t support OGG Theora either. HLS is almost exclusively used with H.264 compression. To use the EMS you must use H.264 compression.
2) If i understand your commands above correctly, you are sending raw uncompressed YUV data from your device to the other computer. That is a ton of bandwidth. To compress it on the PC, you should be able to use the EMS Transcoder but we’d have to work with you on how that would specificially be done. Does your GStreamer on your PC do compression currently?
3) GStreamer can send a stream to the EMS, but it has to be H.264/AAC
