[Question] The discrepancy between yt-dlp command-line results and mpv-android results.

[lvmpv41-yt]

Parden me,
If this place is not the right place for asked such questions..

I have seen developers from MPV VLC ffmpeg here and I have huge respect for all these Dev's dedication non paid.. :(
so this place is the hub of knowledgeable people.

My question or curiosity about mpv Android before asking here i spent many days with google and free Ai's but these Ai's generate more questions then answers..
Come to the point

mpv-android/mpv-android#58

I uses sfan5 special ytdl build of MPV Android such a masterpiece.
I am curious why format-sort does not work as expected in MPV Android .

I have seen posts about this in issue, yt-dlp and reddit..
Yt-dlp guys Said it's external issue and some Said it may be ffmpeg issue . I have no clue as i have no technical skills.

What is expected
ytdl-raw-options=format-sort"=+size,+codec:av1"
It should read both elements size+codec
What happening Actual result.
It's just read one element +size and ignore other elements i have tried many different combinations.

is the reason MPV+ytdl still uses youtube-dl syntax?
As format-sort is introduced in yt-dlp.

Don't laugh but this claude.ai told me this
"actually the real fix is even simpler.
Tell sfan5 to add a dedicated preference for format-sort as a plain string — just like ytdl-format already has — and pass it via:"
kotlinMPVLib.setOptionString("ytdl-raw-options", "format-sort=$value")
