[FFmpeg-user] Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scaler_0'

[Ben Parham]

Hello,

When I use this command in transcoding I face an error. How can I fix this
issue?
This command works in some cameras without error but for other cameras it
has a problem. I would appreciate your help.

Regards,
Ben.
