Direct stream switch over to transcode

[revengineer 142]

Playing with IPTV last night, I noticed that when playing my channels, the streams show initially as "direct" and after 10 s or so they switch to "transcode". Does anyone know why that is and whether there is a way to prevent this?

Probably means an error was encountered so the player switched from direct to transcode.

I see. Problem seems to be "no direct play profile" found. So it seems that the initial description "direct" in dashboard is just an attempt to direct play but it never actually does stream until the transcode starts. I have added relevant log lines below for a cross check of my diagnosis.

If you recall from how to report a media playback issue, we do ask that you supply full and complete log files. thanks.

[revengineer 142]

I do remember and I would if it were easy. Unfortunately, iptv providers have the username password combo in the URLs, so my passwords are all over the log file. If they get lose, I can kiss my subscription good bye. I think we can just put this issue to rest.

 

The above issue will be problematic for future reports. I would have to isolate the testing by restarting emby, which in my case requires a whole server restart because the emby process remains unterminable.
