Please make sure the question is worded well enough to be understood

with "-f bv+ba/b" it will download highest video quality included sound

but if video had no sound, and 540 resolution (it downloaded as maximum 600x600, i think it's a gif) with -f bv it will downloaded : 600x600 maximum quality, but with -f bv+ba/b, it can only download up to 360p

so how i can make it automatic download best quality of videos (if video have no sound) with -f bv, and if video have sound, it will use -f bv+ba/b

i think because it's maybe a gif, so it messed up with yt-dlp config ?

-f bv+ba/b will try to select the best video-only format AND best audio-only format (to merge them), and if that combination is not available, then fall back to best pre-merged video+audio. Since this post does not have an audio track, using bv+ba/b will fallback to b, resulting in the sd format being selected (yt-dlp thinks it has audio, even if it actually doesn't, since there is no metadata available about the format).

I can't think of an -f arg that you could apply generally / add to your config that would handle this. Passing -f bv manually is what you'll need to do for video-only facebook posts. Maybe this could be fixed somehow in the extractor, though

yeah i think so, because resolution is not standard 360-480-720-1080p, so it will fall back to sd 360p instead

i try to download 1080p video which dont have sound, it downloaded 1080p video without any problems

If you want to use a facebook-specific config file, you could add -f "bv+ba/b[format_id!~='^(h|s)d$']/bv" to it. I say facebook-specific config because it would interfere with other sites that use hd and sd as format IDs

np, with other site i just run python code "yt" which automatic use specified config file for all

i tested your "-f" i think it worked
