I'm trying to benchmark a filterchain that includes multimedia filters (in this case with audio input and video output), but I'm having trouble finding a way to start and stop the benchmarking. For instance with this command, I need abench before the filter since it's audio and bench afterwards since it is video, but no benchmarking info is logged.
ffprobe -f lavfi -i sine=d=1,abench=start,showvolume,bench=stop -show_frames
If I use an audio or video filter, then I can get benchmarking data, such as with
ffprobe -f lavfi -i sine=d=1,abench=start,aecho=0.8:0.88:60:0.4,abench=stop -show_frames
So is there a way to benchmark an A->V filter?
