Apply ffmpeg filter on live stream

[papapoipoi]

Hi,

I'd like to apply a crop filtering on a stream, as the camera I use includes several videos of different angles in the same stream.

I try to apply a crop ffmep filtering in the stream but I can't find any way to activate it.

Where can I get a sample of filtering usage in Camera UI interface ? I'm not sure which informations should be included in the parameter field.

Thank you for your help,

Just to comment... I've tried many options before I activated logs and what I see is whatever I try, it doesn't change anything in the logs, as if the filter field was not taken into account at all...

Any suggestion ? Is that a bug ? Thanks
