VLC play stops after several minutes of playing

VLC play stops after several minutes of playing.

We are evaluating VLC to be used in a large deployment of security cameras streaming rtmp video to Wowza and having clients connect via a VLC player. SO far this is the only major issue we found. Latency is one other issue. For Woza to be considered for our deployment we need to resolve these issues. I ruled out network issues in this case and we are evaluating another media server that does not have this issue.

Note that we are running Wowza in Azure

Hi @michael Vassilopoulos, this may be caused by a relatively high bitrate compared to the bandwidth either from the camera to the server or from the server to VLC. It may also be caused by high CPU utilization on the server, eg. if you’re using transcoding. Last but not least, RTSP isn’t the most stable transport, and packet drops happen, especially on unstable networks.

In either case you should be able to see errors and/or warnings in the Wowza logs (which you can obtain via the Streaming Engine Manager panel, or directly on the server console in the /logs subfolder)

I assume you have tested if you can play other streams with VLC? Because it may also be a capacity problem on your machine, e.g. you could try to enable or disable hw acceleration.

This will likely require a support ticket to troubleshoot properly so our support team and SEs can take a look.

What version of Wowza Streaming Engine are you running? Are you using a developer trial license?
