• Video streaming help

      I know this is an extreme long shot, but I just sent this message to some SL help groups and thought I might as well post it here on the off-chance that anyone has any thoughts.

      I wonder if anyone can help me with video streaming. I have been struggling all week and am completely at a loss for what I’m doing wrong – any help very gratefully received!

      I want to live video stream into SL using QuickTime Broadcaster and Streamzilla. This is working great – on the Mac. However PC users can see it in their browser but not in SL – they see a black screen where the video should be. I’ve seen this problem reported before on the SLED list and switching to port 80 was recommended as a solution but that didn’t help – still a resolutely black screen.

      We have managed to do this before, but some months ago, and I’ve read a dozen step-by-step guides and seem to be following instructions, so I’m really baffled as to what I’ve changed. I’ve put all my QuickTime settings below:

      Audio
      Preset: Custom or DSL-Speech – tried both
      Source: Built in microphone
      Gain: 60
      Compressor: MPEG-4 Audio
      Rate: 44.1
      Size: 16

      Video
      Preset: Custom
      Source: Built in i-sight
      W: 320 H: 240
      Compressor: H-264 OR MPEG-4 Video OR Sorenson Video 3 – I’ve tried all. All are fine on Mac – black screen on PC
      Depth: Colour
      Quality: High
      Frames/s: 23.98
      Key Frame: 150
      Limit Data Rate: 150 (NB: Have varied this from 75-300 – nothing)

      Network:
      Preset: Custom
      Transmission: Manual Unicast
      Address/Audio/Video: All provided by Streamzilla

      Streamzilla settings:
      Player Type: Quicktime
      Delivery: Darwin
      Metafile Format: mov
      Protocol: RTSP
      Port: 80 (NB: Have also tried 554 – fine on Mac, nothing on PC)

          Joanna, if I were you, I would ask Alan J. Cann (http://www.microbiologybytes.com/blog/about/). He is a master of these things.

          I’m having issues too. There has been a recent quicktime viewer update, so I’m not sure if that’s the problem or if it is just Second Life being Second Life. I don’t think you’re doing anything wrong Jo.

          @Bertalan – thanks, I’ll get in touch with him now.

          @Andy – ah, SL being SL, always the most likely option! I’ve called LL again and this time they said they had heard of this problem before and would try to find the solution, so will report back when I hear anything.
