RTP Streaming performance problems

ottoblom — Sat, 03 May 2014 00:16:17 GMT

Hi There,

I followed these instructions - GStreamer RTP Streaming to set up my PC as the sender and the i.mx6 as the receiver (playback on LCD). Audio output was disabled in the script as our board does not support it yet. The video does show up, but the performance is quite abysmal - less than 1 frame per second. My PC is a i5 so I would imagine that is not the problem. Any ideas on what could be going on ? I'm using the 4.1.0 BSP. The receiver log is shown below

Thanks and have a great weekend,
