From michael at intervyo.com Wed Aug 3 11:13:08 2016 From: michael at intervyo.com (Michael Benchetrit) Date: Wed, 3 Aug 2016 09:13:08 +0000 Subject: [Fiware-creatifi-coaching] Kurento record issue Message-ID: Hi, My name is Michael, I'm working for the startup Intervyo. Our solution uses Kurento to capture video from browsers. Kurento Media Server is installed on our server since a year and everything was working great but after a day, without any further changes made to the code, we have encountered a strange issue with files generated by the recorder. Basically, kurento produces empty-0 byte webm files (see attachment). After doing a lot of research, I was able to identify the origin of issue : neither audio (microphone) nor video (webcam) packets are sent to the recorder during the capture (see screenshot attachment). However, I can't figure out what goes wrong. I tried many solutions to fix this issue like : - Restart the KMS - Look at the KMS logs (no errors) - Try on different computers with working webcam/microphone - Try on different wifi networks (in case of packet being blocked by the firewall) None of the above solutions resolved the issue. It's important to mention that we are using the KMS version 5.1.5 . Likewise, I saw a similar issue posted on this forum that you were able to fix. My question is : can we potentially have a skype call so that we can discuss more easily ? Thanks, Micha?l BENCHETRIT -------------- next part -------------- An HTML attachment was scrubbed...
