It doesn't seem supported by mpv:

No sub streams in file af343964d7-textstream_eng=1000.mp4.
Can not open external file af343964d7-textstream_eng=1000.mp4.

[3052]

are you saying that SmPlayer is just a front end for MPV?

[smplayer-dev]

Yes.

[3052]

is that documented? I don't see a single mention of MPV here:

https://github.com/smplayer-dev/smplayer

[smplayer-dev]

The website mentions it https://www.smplayer.info It's also in the about dialog.

The website mentions it https://www.smplayer.info/

uh, where? I just checked and I dont see a single mention of it

[smplayer-dev]

"Now SMPlayer supports mpv as well" which links to https://www.smplayer.info/en/mpv

I think it should be WAY more obvious that SmPlayer is just a frontend for MPV. that info should be included on one or both of these pages:
