Hi , i am using the IPTV plugin in emby and add the m3u8 link to that from flussonic
Use this app and play the item. During playback press DOWN on the remote. It will bring up the OSD. Under the Playback Position Bar are buttons. One of these buttons looks like a graphic equalizer with 3 sliders. Click that button. It will open the Playback menu. Choose the resolution/quality. This will allow you to try to pick something that works for you and does less buffering/retrieving. Once you drop the bitrate below what can direct play it will switch to transcoding and use the resolution choice you made. This will allow you to custom tailor the transcoding that goes on to the resolution and bitrate you desire. Try this and let us know if this helps fix the problem. Thanks.

Are you sure in your flussonic settings that 1920x720 is correct? That isnt a 16:9 aspect ratio and that is also likely why the Roku is struggling to render it. It might not have anything to do with throughput. It might be a scaling issue and the Roku is struggling keeping up with the framerate. What is the framerate flussonic is able to transcode at? It might be below what the framerate of the media is and the Roku has no choice but to struggle.
In any case, the app has the resolution/quality choices in the OSD playback menu for this exact reason. Emby server can act as a buffer and transcode too. To rectify issues when you just want to play something. When it just has to work that in-app OSD playback menu is the answer.
