How to generate 3 different H.264 streams for 1 CSI stream ?

We're looking for some advices about using GStreamer to generate several H.264 streams from one 720p 25fps CSI stream.


It's quite simple to generate one H.264 RTP stream for 1 CSI input.But we would like to generate 3 different H.264 streams, i.e. :

  • 1 x RTP H.264 720p 25fps
  • 1 x RTP H.264 800x600 25fps (resize + crop)
  • 1 x RTC H.264 720p 6fps (different framerate)


Do you think it's possible ? Can GStreamer use the IPU to generate 2 streams with different resolution ? As the VPU encodes 3 differents streams, it means 3 pipes for GStreamer and lot's of memory copy.


So, we would be interested if someone has already a feedback about a similar use case.
