Description

I want to merge a video with several audio files, but get this error：org.bytedeco.javacv.FFmpegFrameFilter$Exception: avfilter_graph_config() error -22。 My filter is "[0:a]adelay=0|0[a0];[1:a]adelay=3000|3000[a1];[2:a]adelay=10000|10000[a2];[a0][a1][a2]amix=inputs=3[a]". Another error is the sample rate of video grabber is 0. image

Contributor guide

Research direction
Examine the filter graph string and verify each audio stream's sample rate and format. Check the JavaCV version and FFmpeg library version for compatibility.
