Hi all,
I want to implement process_command for vf_scale.c and vf_crop.c in order to
use zmq to change
scaling and cropping dynamically.
I have implemented it using av_opt_set() and calling config_props() for
scale and config_input() and
config_output() for crop. I am using the config_-functions because they
handle variable parsing and
checking of the values. But I do not know if this is the right way to do it
and if it is safe to
call these functions from process_command.
Maybe someone can comment on these implementation or outline a way to
implement process_command for
these filters.
I attach patches including my implementation so far.
Thank you very much in advance
Bernd
If it works I guess it should be ok. But newly added stuff should be
somewhere documented...
Yes. Thank you. I will have a look a the developer documentation again and add a commands entry to
the filter documentation.
Bernd
