Those functions set the field of obj with the given name to value.
[in] | obj | A struct whose first element is a pointer to an AVClass. |
[in] | name | the name of the field to set |
[in] | val | The value to set. In case of av_opt_set() if the field is not of a string type, then the given string is parsed. SI postfixes and some named scalars are supported. If the field is of a numeric type, it has to be a numeric or named scalar. Behavior with more than one scalar and +- infix operators is undefined. If the field is of a flags type, it has to be a sequence of numeric scalars or named flags separated by '+' or '-'. Prefixing a flag with '+' causes it to be set without affecting the other flags; similarly, '-' unsets a flag. If the field is of a dictionary type, it has to be a ':' separated list of key=value parameters. Values containing ':' special characters must be escaped. |
search_flags | flags passed to av_opt_find2. I.e. if AV_OPT_SEARCH_CHILDREN is passed here, then the option may be set on a child of obj. |
Set a binary option to an integer list.
obj | AVClass object to set options on |
name | name of the binary option |
val | pointer to an integer list (must have the correct type with regard to the contents of the list) |
term | list terminator (usually 0 or -1) |
flags | search flags |
