How to remove only one track (not all) from video file container (.vob or .mkv) using ffmpeg?

Answer 1

You just solved my av1 muxing issue, which requires -map 0 to include the subtitle font from original-video.mkv.

ffmpeg.exe -i original-video.mkv -i svt-av1.ivf -map 0 -map -0:v:0 -map 1:v:0 -c copy output.mkv

-map 0 selects everything, including the subtitle font which is, erroneously, in the wrong stream of the input file. -map -0:v:0 remove all video. -map 1:v:0 re-adds video from second input, which is the re-encoded AV1 of original-video.mkv.
