How to save all audio tracks when converting ffmpeg video?

Question

fmpeg

I convert the videos I need to the format hevcusing ffmpegthe following parameters

ffmpeg -y -i inpit.mkv -g 30 -c:a copy -c:v hevc_amf output.mkv

and everything is great. But one unpleasant problem was discovered - if there are several audio tracks in the video, then only one of them remains at the output. What keys to specify so that all the tracks in the file are copied? I read about the parameter -map, but this is if I need to add several tracks, and I want to get the sound as it was in the original.

Answer 1

ffmpeg -y -i input.mkv -map 0:a -g 30 -c:a copy -c:v hevc_amf output.mkv

-map 0:atogether with -c:a copyallows you to copy all audio tracks as they were in input.mkv.
