Hi all - could someone please shed some light on this issue.  I swear I had some data in TranscodeInformation at one stage.

 

this is on _sessionManager_PlaybackProgress

 

e.Session.Playstate.PlayMethod is definitely MediaBrowser.Model.Session.PlayMethod.Transcode

 

The emby log shows that it is definitely transcoding,

 

however e.Session.TranscodingInfo is null.

 

In the emby log, it shows that the TranscodeReason is Unsupported Container.  I don't understand why TranscodingInfo is null when it is definitely transcoding, and definitely PlayMethod.Transcode.

 

@@chef

 

Thank you guys.

 

Anthony

And code snippets ...

            SessionInfo test_session = this._sessionManager.GetSession(e.Session.DeviceId, e.Session.Client, e.Session.ApplicationVersion);

            if(test_session != null)
            {
                Plugin._iLogger.Info("FOUND SESSION AND IS NOT NULL, LETS SEE IF ITS TRANSCODE INFO IS NULL ...");

                if(test_session.TranscodingInfo != null)
                {
                    Plugin._iLogger.Info("TRANSCODING INFO EXISTS!!!!!!!!!!! ...");
                }
                else
                {
                    Plugin._iLogger.Info("NOPE  TRANSCODING INFO DOESNT EXIST ...");
                }
            }


            if(e.Session.PlayState != null)
            {
                if(e.Session.PlayState.PlayMethod == MediaBrowser.Model.Session.PlayMethod.Transcode)
                {
                    //lets find where transcoding information is..
                    TranscodingInfo tInfo = e.Session.TranscodingInfo;

                    Plugin._iLogger.Info("IS TRANSCODING ......");

                    if(tInfo != null)
                    {
                        Plugin._iLogger.Info("AND TRANSCODE INFO IS NOT NULL ......");
                    }

                }
            }

is "Unsupported Container" (a remux) really trans-coding though, I dont think Emby considers this trans-coding, it is direct play as far as Emby is considered I think.

It isn't instantly set the transcodingInfo. If you are reading the session info it will be blank for transcodingInfo initially right after you start. After the first 10 seconds or so it will populate. You need to allow for this. TranscodingInfo will not be sent when the transcoding progress is complete at 100%. This will be seen in the session info when complete since transcoding info within the session info is not available.

Anything that has "transcoding reason" is transcoding. Call it Remux/DirectStream/Transcode but all forms of those require ffmpeg and produce TranscodingInfo inside the Session. It is not considered DirectPlay. Check the dashboard/stats-for-nerds and see. ;)

Yep, I totally agree with that, and I do accommodate for it, thats why I chose this event type, and I let the media play for 5-10 minutes and basically blast the emby log with a check for if its null, and even after 5 minutes its null :)

 

Edit: but for the entire 5 minutes, the emby dashboard shows the media is transcoding :)

So for now, I get %is.transcoding% from PlayState.PlayMethod, and if transcodeinfo is null, it won't populate the rest of the %transcode.* tokens.. until I resolve this one :)

and thus yields;

And I just realised this is only occuring when playing Recorded TV shows.   When I play other files that aren't recorded, the transcoding information exists :)

Its only when its transcoding recorded tv shows/media.

Following two is not working for me -

"%transcoding.width%" "%transcoding.reasons%"

 

Have i missed something? and also noticed when its false for transcoding logging is constant continues sending info to the script.
