A list of supported channel layouts.
The list works the same as AVFilterFormats, except for the following differences:
- A list with all_layouts = 1 means all channel layouts with a known disposition; nb_channel_layouts must then be 0.
- A list with all_counts = 1 means all channel counts, with a known or unknown disposition; nb_channel_layouts must then be 0 and all_layouts 1.
- The list must not contain a layout with a known disposition and a channel count with unknown disposition with the same number of channels (e.g. AV_CH_LAYOUT_STEREO and FF_COUNT2LAYOUT(2).
