Automatic setting of recorded video cursor playback position
Answered
Hi
I need to be able to display a constantly delay of the live feed from muliple cameras. I am recording the cameras and play back the recording (time now - 2 minuites).
To acieve this I am just manually clicking on the timeline roughly 2 minuites back and letting it play, this works well however not reliably as the video feed (rtsp) may glitch or something and then the video freezes, to restart I just need to click on the timeline agian. If one camera freezes the other way still continue to play fine.
I am wondering if a plugin can be developed or exist that may automate this process of clicking on the timeline. It could just be written to set the recording playback time cursor to a specific time and executed every minuite.
Thanks

Hello Stuart,
Would you please give more details on your objective? Why this delay of 2 min is crucial in you scenario? What is this delay for?

We are a Indoor Skydiving Wind Tunnel.
In our small world this is a serious sport and people pay a lot of money for tunnel time. Partisipants will generally train in the tunnel for 2 minuites and then take a 2 minuite break. During thier break they watch back the video of the prior session.
Currently we have 1 camera running this setup on a raspberry Pi. We want to add a few more camera's but with each camera running on an individual rPi it gets a bit complicated.
I have this set up on this software and it works very well except the glitching and freezing issues detailed above.
I would like to have the plugin developed if possible as that will ensure the system can run 24/7 without to much maintenence.

Hi Stuart,
Looks like you don't need the client to be interactive, right?
Probably you can develop a simple web page that will always request video with a hardcoded delay?

I want to use the client as we will have 5/6 camera views spread across 4 screens and the displaywall and layout features give me exactly what I need.

Hi Stuart,
Unfortunately, at the moment there is no option in GUI client for introducing a certain delay to the the displayed video.
Here are general considerations.
Your could have a try for eliminating glitches and freezes. Is your raspberry Pi capable enough of carrying the video stream load: 6 cameras means 2 streams (hi-res, low-res) times 6, i.e. 12 camera->server streams and 12 server->GUI client streams? Make sure the network, server-camera and server-GUI client connections are reliable: no packet loss, no carrier error, no unusual delays; no one steps over the cables, cable connectors are firm etc. Try to change camera. Try to reduce the quality of the streams being pulled and displayed.
Since you client is not interactive and has constant position, your could develop a simple program, which would emulate mouse lelf-button click at certain coordinates on the screen corresponding to 2 minutes delay position in the GUI client.
