* Playing on the Roku Emby App, some 265 encoded files are super choppy. * Same thing happens when playing on Android Emby App. * However, if I use VLC player on my phone (using 3rd party player setting on Emby Android), it is perfectly smooth. This leads me to believe something is wrong the Emby Player itself, on both Android and Roku, and not an issue with the server. * I've seen several people post about this same issue with 265 encoded files on the forums, but no particular resolution was found. * I have included the server logs as well. embyserver.txt

When Emby asks the VLC player to play the file it is no longer streaming. Emby sends an intent/action which starts VLC with a link to the file you have asked to play. It is no longer really using Emby after this point. VLC takes over the playback entirely as a file. When VLC is done playing it must send back the progress/played states to Emby after you play so that Emby can update these. Otherwise using VLC you would have no resume or watched status updates. When transcoding occurs it will create a streaming friendly version using an m3u8. It is no longer using the original file. That is why you notice it is smooth. The issue is your file. Remux your file should be a quick process under a minute. Then test the file inside Emby using an Emby app and if it no longer has the issue this is your solution. Conversely, in the Roku Emby app you can use the cog/gear during playback and select "Attempt Playback Correction" which will then repackage the file using an m3u8 and copy the streams. That will also fix the playback issue but must be done every time.
