ipTV : Advanced Playback Options for smoother streaming (Android Cosmi TVplayer)

[Stev]

For Live TV on my Android ipTV players : Sometimes I have freezing problems, especially with 1080p channels.
I see in Cosmi TV player you have several Advanced Playback Options.
Is there any I can change to have smoother streaming : Tunneled Video Playback, Decoder options (HW/SW), H264/AVC, HLS Extractor Options, Video buffer, datasource (Cronet or OkHttp),... ?
