Store the value in the field in ctx that is named like key.
ctx must be an AVClass context, storing is done using AVOptions.
buf | the string to parse, buf will be updated to point at the separator just after the parsed key/value pair |
key_val_sep | a 0-terminated list of characters used to separate key from value |
pairs_sep | a 0-terminated list of characters used to separate two pairs from each other |
