Hi Everyone, I am making a mobile music app where the user can add FX to current playing music through a two dimensional pad. I am using FFmpeg, libavfilter in C++ to add FX to the audio. In FFmpeg you can create an audio filter and set it parameters and initialize a graph.
My problem is since the user will use a FX pad to change these parameters with their fingers I need to be able to modify these parameters during runtime. Looking at ffmpeg filter documentation, it says the following: "Some options can be changed during the operation of the filter using a command. These options are marked âTâ on the output of ffmpeg -h filter=. The name of the command is the name of the option and the argument is the new value." I looked at aecho, agate, acrusher and more but nearly all the effects I want have 0 modifiable option which makes my FX pad nonadjustable. Is there a way to make ffmpeg audio filters change their parameters during runtime? I could really use the help, thank you!
