I have a difficulty in accessing and modifying options.
From example codes, I see some field_names, such as “volume.resolution.x”, “aux_stream.type”, “frame_info.supports_aux”.
I have no idea whenever I have to change options, like image resolution, fps, target volume size, etc. I think there must be a document for predefined field_names.
Where can I find the whole list of field_names?
As mentioned in the previous link, a simple way to change settings is to serialze options to your file system, and load them in your application. Then you’re able to experiment with different settings by simply changing options in a textfile instead of changing options in code.
