Just an idea. I think you can pipe the downloaded data directly into ffmpeg (or gstreamer), not consume temporary disk space or RAM and skip the post-download merging.
Proof of concept in bash:
ffmpeg -hide_banner -nostdin -stats -loglevel fatal \ -i <(cd "$CACHEDIR/audio"; yt-dlp --live-from-start "$URL" -f 140 -o-) \ -i <(cd "$CACHEDIR/video"; yt-dlp --live-from-start "$URL" -f 133 -o-) \ -vcodec copy -acodec copy \ -map 0 -map 1 -movflags +faststart outfile.ts
produces a file that is immediately playable and seekable with VLC.
So, maybe ytarchive could use in_fdN, out_fdN = os.pipe(), -i pipe:{out_fd1} -i pipe:{out_fd2} and write to those fds directly.
in_fdN, out_fdN = os.pipe()
-i pipe:{out_fd1} -i pipe:{out_fd2}
