• Recording RTP stream in segments based off traffic

  8 novembre 2018, par MapZombie

  I’m looking to record multiple multicast RTP audio stream into chunked timestamped files based off the traffic on that live stream.

  For example the application would listen to the IP address/port then start recording when RTP traffic is beings streamed, then stop the recording and save the file when the RTP traffic stops.

  I’ve been trying to find examples for how FFMPEG or Gstreamer could do this but have not found anything concrete. Is this possible with one of these applications ? If so could you provide an example ?

  Use SATD based mode decision for block sizes below 16x16

  This commit makes the encoder to select between SATD/variance as
  metric for mode decision. It also allows to account chroma
  component costs for mode decision as well. The overall encoding
  time increase as compared to variance based mode selection is about
  15% for speed -6. The compression performance is on average 2.2%
  better than variance based approach, with about 5% compression
  performance gains for hard clips (e.g., jimredvga, nikas720p, and
  mmmoving) at lower bit-rate range.
