• Streams stop when creating a quad split Multi-viewer using FFMPEG [closed]

  6 avril 2024, par Chris Parker

  Created a FFMPEG script that takes in 4 SRT Live Streams and displays them in a quad split MV. However when I launch this script all 4 SRT streams will play but 3 will pause and 1 will play.

  


  ffmpeg \

  getting a lot of the below error ;

  


  16:48:49.628704/SRT:RcvQ:w2!W:SRT.qr: @214003038:No room to store incoming packet seqno 649744568, insert offset 7190. Space avail 0/8192 pkts. (TSBPD ready in -12342ms, timespan 6093 ms). GETTIME_MONOTONIC drift 0 ms.


  


  I've tried smaller resolution and adjusting buffer sizes as well as the other flags but I'm not sure what else I can do.

  


• phplondon conference 2008

  9 juin 2010, par Mikko Koppanen — Everything else, Imagick, PHP stuff, phplondon08

  To summarize it : I had fun My conference preparations started about two weeks before the conference. The PHPLondon fellows (Paul, Matt and Richard) asked me to do a small presentation about Imagick at the pre-conference social event. The presentation I assembled ended up being a little over two hours, give or take. The hardest part was to trim down from two hours to about 40 minutes (I didn’t want to bore the people with too many code examples). The slides are available at http://valokuva.org/talks if you need them for some reason.

  My conference day was pretty hectic from the beginning to the end. I gave a few demos about the products that we represent and the moment I opened my mouth for the first time people started leaving the room. I hope that it had something to do with the “My Framework is better than yours ?” talk starting at the same time

  I met quite a lot of new people at the conference and of course it was nice to see the familiar faces from other conferences and PHPLondon meetings. I was especially happy that I was able to answer the questions Nigel James had

  A huge thanks to the organizers for making this day possible !
