[FFmpeg-devel] How to specify AV_OPT_TYPE_DICT type options on command line

[Thilo Borgmann]

Hi,

I'm trying to pass an option into a new filter of type AV_OPT_TYPE_DICT.

After compilation I wonder how to specify this dictionary via the
command line...

ffmpeg -i in.avi -vf filter=opt_of_type_dict=??? out.avi

Grep reveals no other filter using the dict type for an input option.
Anyone knows or at least can point me to where it is handled in the code?
