Re: [SR-Users] KSR.sdpops.remove_media is not working as expected

Hello, from the logs it looks ok, no error etc..: 3(237) DEBUG: app_lua [app_lua_sr.c:1651]: sr_kemi_lua_exec_func_ex(): param[0] for: remove_media is str: image 3(237) DEBUG: sdpops [sdpops_mod.c:1037]: sdp_remove_media(): attempting to search for media type: [image] 3(237) DEBUG: sdpops [sdpops_mod.c:1053]: sdp_remove_media(): stream 0 of 0 - media [image] 3(237) DEBUG: sdpops [sdpops_mod.c:1061]: sdp_remove_media(): removing media stream: image 3(237) DEBUG: sdpops [sdpops_mod.c:1053]: sdp_remove_media(): stream 1 of 0 - media [audio] This is probably a more frequest used function from the module. Can you double check if it’s really not removed on the network layer?

Can you execute it with debug logging activated, the function should output some debug logs about its working.

Unfortunately, it is not removed from outgoing message. True. I also believe that msg_apply_changes is not recommended, hence I am not using that.

Usually the message altering functions will only be applied when you send out the message due to performance reasons. You can force it in the cfg with the function “msg_apply_changes” – then you should be able to see it as well in the log. But using this function has other side effects and is not recommended if you don’t need it.
