Hello everyone, First of all thanks for taking the time to check my issue. The error I get is the following:

[ERROR] [1623244822.830661872]: Invalid 'stop_frame' -2147483648 for video which has -2.76701e+17 frames. Setting internally (won't be shown in dynamic_reconfigure) 'stop_frame' to -2.76701e+17
[ERROR] [1623244822.830673509]: Invalid 'start_frame' 0, which exceeds 'stop_frame' -2147483648. Setting internally (won't be shown in dynamic_reconfigure) 'start_frame' to 0.

Here is my launch file.

Any ideas? Thanks in advance.
