Describe the issue
When I play a 4k video using flutter + video_player_tizen it lags a lot. When I open it with another player in the same Samsung TV it plays very smoothly.
Also the colors of the video compared to other players feel very pale. Is there any known reason for this?

To reproduce

• Play a heavy 4k video with the plugin

if you want to play 4K video on Tizen TV, I suggest you use video_player_avplay plugin.

I get this error when I use video_player_avplay

GStreamer-WARNING **: 19:01:46.830: Failed to load plugin '/usr/lib/gstreamer-1.0/libgstffmpeg.so': libclearkey.so.0: cannot open shared object file: Operation not permitted

Do you set the right api-version when building tpk?

api-version	TizenOS version
6.0	6.0
6.5	6.5 ~ 9.0
7.0	7.0 ~ 9.0
8.0	8.0 ~ 9.0
9.0	9.0
10.0	10.0

and could you please share you TV version?

[aleksanderndoci]

Yes I have set the correct api version (6.0).
The tv I am testing on is running on Tizen 6.0 with sw version 2220
