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.
I just answer myself to my posting as a reminder. Maybe my posting has been
overseen.
If I am totally wrong here (in this list, with my implementation or with the patch format), please
let me know.
Thanks a lot
Bernd
