React-Native/Expo | Cannot use libx265

[Michota]

I want to compress mp4 to m3u8, but make its size smaller too.
For this moment I use

-i ${inputUri} -c:v copy -c:a copy -b:a 128k -force_key_frames expr:gte(t,n_forced*${hlsTime}) -f hls -hls_time ${hlsTime} -hls_list_size ${hlsListSize} ${outputUri}
but the size is the same as input uri.

I wanted to use libx265 as they recommended in that post, but i get an error when i run this command

-i ${inputUri} -c:v x265 -c:a copy -b:a 128k -force_key_frames expr:gte(t,n_forced*${hlsTime}) -f hls -hls_time ${hlsTime} -hls_list_size ${hlsListSize} ${outputUri}`;
Error: Unknown encoder 'x265'.

I had video package installed before

/// app.json
[
"@config-plugins/ffmpeg-kit-react-native",
{
"package": "min-gpl"
}
]
but even after i changed it, removed app from my device, and reinstalled it, its still saying that it is unknown encoder...
I use Expo SDK51.

Help me, please!

My enabled encoders list has libx256, not x265.

Yeah, I was too sleepy to close this thread. Its working now.
Where can I get the names of encoders that I can use? Is it the packages section on github wiki?

You can find the codec list from build.log.

@juha-h you were nice to me. Thanks again.
May you also try to answer this question about --speed flag?
Thanks, once again.
