Video lag #11284

Open darshan-crypto opened 5 months ago

Expected Behavior

I expected the video feed to stream smoothly and without any significant delay.

Current Behavior

The video feed is lagging consistently, with a delay of several seconds between real-world events and their appearance in the video stream.

This will likely be better in v5.0

As another data point. I also have noticed my streams become more laggy and choppy recently recently.

Here is a video from version v4.4.0

Here is a clip after I downgraded to v4.2.7

Adding this as a data point. Not sure what has changed in the last year, but I hope it gets better in v5.0! When is v5.0 supposed to be released? Also, If I build the project from source, would I be able to get the v5 improvements now?

Yeah the daily is running gstreamer 1.22.12 vs 1.18.5 in the older versions. Also, I have been working on adding an alternative QtMultimedia based video receiver that uses ffmpeg instead

I got curious and downloaded the apk from here https://github.com/mavlink/qgroundcontrol/actions/runs/9929355840

I can confirm the video is much better. Also it looks like there are big changes coming to QGC in the next release. whoa!

Since there seems to be a lot of changes in this build from the last release. I'll probably stick with running 4.2.7 for the time being just to be safe. I would be interested in helping test the next version when the time comes. Where is the best place to stay in the loop on development?
