• Universal Media Server in Ubuntu 14.10

  15 mars 2015, par Christopher Champion

  I just got universal media server to run in Ubuntu 14.10, they took mencoder and ffmpeg out of the repos so I had to go find them and now it runs but when I try to play a movie on my ps3, it takes a min to load and then on my ps3 side, it says that the media can’t be played and it says it with most of everything I try to play...it worked with 14.04 but not this one.. I’m actually considering downgrading to 14.04 because of this issue.. can anybody help ?? thanks !

• Low latency routing of rtp input to rtsp output with ffmpeg on a server

  29 mai 2020, par guillefix

  I want to be able to do some simple low-latency screen share. I know peer-to-peer would be the lowest latency, but it seems using an intermediate server is a lot easier to setup. I have found this awesome little library, which sets up an RTSP server, which I'm running on my digital ocean server. I then :

  



  

  1. Set up OBS to stream using RTP to the server on port 8558 with libx264 encoding.

  


  2. Run ffmpeg -re -stream_loop -1 -i rtp://127.0.0.1:8558 -c:v libx264 -c:a aac -f rtsp rtsp://localhost:8554/mystream on the server.

  


  3. Open rtsp://<server ip="ip">:8554/mystream</server> on VLC.

  


  



  However, the latency seems to be quite high. With my crappy internet it must have been like half a minute. A friend with better internet saw it fluctuating between 4-15 seconds. Furthermore, there seems to be a lot of artifacts on the video (problems with encoding ? I'm not sure why these happen ?)

  



  I attach below my OBS settings, and an example of artifacts.

  



  My question is : is there some settings on OBS and on ffmpeg that would allow this to have as low end-to-end latency as possible, while not having too many bad artifacts ? I'm not very well versed on video encoding and streaming, so this is all quite new to me. I'm willing to learn !
