I am attempting to create a single VLM configuration that allows me to output 2 mosaics, one with 3x3 grid, while the other has a 2x2 grid. The grids will be populated from the same pool of inputs, but in different arrangements. I am using position=1 and order= to specify the arrangements of both.
I almost have it working, with the exception of a rather odd behaviour. The 3x3 mosaic output is consistent and correct with the order I specify. While the 2x2 output is not, and changes each time I restart vlc.
My current config is shown below. In the 2x2 mosaic, I have specified order="1,2,3,5" but what is shown is not consistently the same cameras with those id numbers, as is correctly output in the 3x3 mosaic.
Wondering if mosaic-bridge filter doesn’t support multiple concurrent transcodes, or whether there might be a bug. I have not been able to find, with any online search, someone else attempting to do this, successful or otherwise. So it genuinely could be a bug. Or I have screwed up - that being more likely.
Thoughts anyone?TIA.
Cheers,
Damo.
