3 x 3 Layout Issue #75

Closed the-real-rob closed 2 years ago

the-real-rob commented 4 years ago

I have opened the layout file for 1920x1080 screen size and edited it with the 9 cameras. I have also tested each RSTP stream in VLC.

The issue Im having is that only 4 cameras on the 9x9 grid are showing up, namely, grid slot 2,3,4,5. The remaining blocks are empty.

I copied the code from the 9x9 layout file into the default layout file.

Is this correct and what are the best methods to follow with regards to using other layouts (i.e. 9x9 / 3x2 etc)

Please post a redacted version of your current layout file.

Here is the content from the file - appreciate your assistance! I have simply removed the rtsp links, otherwise the file is the same as what I am currently using.

Are the sources higher resolution than 640 x 360? What were the results of performing the debugging steps in the README.MD file?

Thanks

The individual cameras are full HD 1920x1080. I will dive into the readme.md file and follow the steps. Apologies for the delay in getting back to you.

Anonymousdog commented 3 years ago

You'll never squeeze 9 full HD feeds onto a single display. They need to be the same or smaller resolution as their display windows.

Thanks

I agree with Anonymousdog. In my testing, I can fit at best 2 x 1080p streams on a 1080p monitor along with 2 low res streams (640x360). You could maybe get 4x 1080p streams on a 4k monitor, but compressing the stream is very taxing to the GPU of the pi. You'll never get 9 full HD streams to be displayed on a monitor.

You could have the other streams off-screen and rotate them on.

the-real-rob commented 3 years ago

I have been successfully using the default layout which is a 2x2 layout and the cameras have been performing great, no issues at all. I have only recently tried to increase the grid to 3x3 and thats where the issue arises where only 4 out of the 9 cameras in the 3x3 grid appear. the other 5 camera grid blocks are empty.

Im assuming the cameras adjust their output resolution on the raspberry pi when the grid size differs.

Brickabrak commented 3 years ago

I'm glad you're able to get so many HD videos playing. The blank videos are (from my experience) places where there was no more GPU RAM available, so they can't be displayed. The cameras don't know the window size that was given, so won't adjust based on that. From my testing cameras will lower the quality and bitrate to respond to a limited bandwidth, but never the resolution.
