How to implement ffmpeg filter_complex in c++ code ?
6 octobre 2020, par FluffyI am trying to implement C++ code which uses an FFmpeg filter to merge 2 mono audio streams from input video into 1 stereo stream. The filter itself can be found easily enough in several sources :


FFmpeg : How to merge all audio streams into stereo


http://underpop.online.fr/f/ffmpeg/help/amerge.htm.gz


My question relates to how I can implement this in code. I am using the exact same code found in the FFmpeg examples here :
https://ffmpeg.org/doxygen/trunk/filtering_audio_8c-example.html


I just change the filter_descr variable to :


static const char *filter_descr = "[0:1][0:2] amerge=inputs=2";



When I use this I get the following exception :
Output pad "default" with type audio of the filter instance "in" of a buffer not connected to any destination
I get an Invalid Argument -22 exception when I'm configuring the filter graph


if ((ret = avfilter_graph_config(filter_graph, NULL)) < 0)
