UnderMiner 11 Posted January 21, 2018 Share Posted January 21, 2018 (edited) Hello, When attempting to play recorded TV, the controls disappear and we are presented with a black screen with no video or audio playback.We have playback of the same content in Firefox. All machines are rebooted and up to date. This behavior persists for two days (perhaps after latest server update to 3.70). I shared the log files at the following link. https://1drv.ms/f/s!AnfmLnbQksWOhytOE0vZjYY-aJvZ Any help is appreciated.

UnderMiner 11 Posted January 21, 2018 Author Share Posted January 21, 2018 Hello, I changed the crf back to the default with the same result. I placed a new set of logs at the link above. Please review and let me know of any additional troubleshooting steps. Link to comment Share on other sites More sharing options...
Luke 37029 Posted January 21, 2018 Share Posted January 21, 2018 can you provide a sample video for testing? thanks ! Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted January 21, 2018 Author Share Posted January 21, 2018 Hello, I placed a sample video in a folder at the link above. I included the associated log file along with screen capture of the task manager and the Emby console while playing back on Firefox. There is no ffmpeg transcode or any other activity when trying to use Emby Theater. Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 21, 2018 Share Posted January 21, 2018 (edited) In the store app, black screen for 20 seconds, then it plays with no audio. It's 6 channel AAC. I have a feeling that's the problem. When I play it in windows media player, there's no sound there, either. It plays fine in the desktop app. On your windows PC, you should use the desktop app It's the audio. I lowered the bitrate to force transcoding, and it wouldn't play. Looking at the log, the audio was stream copied. Edited January 21, 2018 by Doofus Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 21, 2018 Share Posted January 21, 2018 (edited) OK, this is curious. I just tried playing a movie I have that has 6 channel AAC. It plays, fine. There must be something odd in the encoding. I remuxed it, and it still won't play, correctly. Transcoded it in Handbrake, audio to 2 channel AAC, and it plays, fine Edited January 21, 2018 by Doofus Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 21, 2018 Share Posted January 21, 2018 I think I see an issue. Pulling up the details media info, there's no bitrate and no stream size. So i think windows doesn't know what to do with it. It looks like ffprobe in the server is trying to fill the blank, but I think it's using best guess. My movie with 6 channel AAC, shows a bitrate and stream size. Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 21, 2018 Share Posted January 21, 2018 And the audio has problems in VLC, too. MPV standalone converts to stereo and it plays. Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 21, 2018 Share Posted January 21, 2018 Just thought I'd test one more thing. Adding AAC pass-through to mpv, the audio doesn't play. Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted January 22, 2018 Author Share Posted January 22, 2018 (edited) Hello Doofus,Thanks for the excellent testing. In my case, I have not changed any TV recording settings for a long time (months) and this issue started on January 19. I record every day and files from Jan. 18 play correctly.The files do not play with the Windows app store Emby theater program or Emby theater on Xbox.They do play using Emby on Firefox and with VLC media player (v 2.2.8).They also play correctly using DLNA to my Panasonic TV but the volume is lower than previous recordings.I could not locate the audio settings for recorded TV in the Emby Server management page.

Guest asrequested Posted January 22, 2018 Share Posted January 22, 2018 (edited) Do you use the convert recordings, option? Edited January 22, 2018 by Doofus Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted January 22, 2018 Author Share Posted January 22, 2018 Yes, the "Automatically convert recordings to a streaming friendly format" feature is turned on. Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 22, 2018 Share Posted January 22, 2018 Ok, so it looks like ffmeg is not converting the audio, correctly. That will have to be looked at. In the mean time, try selecting 'preserve original audio'. The audio will mostly be AC3, which is widely supported. Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted January 22, 2018 Author Share Posted January 22, 2018 I will change the setting. Thanks. Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted January 23, 2018 Author Share Posted January 23, 2018 After changing the settings, the recorded TV playback is working correctly. Until this is fixed, we will have larger file sizes but I'm sure it will be addressed over time. Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 23, 2018 Share Posted January 23, 2018 The AC3 track shouldn't be much bigger. I'm glad you have a workaround. Link to comment Share on other sites More sharing options...

UnderMiner 11 Posted January 23, 2018 Author Share Posted January 23, 2018 For 30 minutes of video, the .ts format is 3.6 GB and the previous .mkv format was 1.2 GB. I had the crf set at 25 and now it is at 23 but I don't believe this is active in the .ts format. The good news is that the audio and picture quality are very good. My eventual goal is to have high quality audio with reasonable video (we are fans of the Voice and appreciate the better multi-channel audio). We use an HDHomerun OTA but we only have four channels available in Canada. Fortunately, it covers most news and regular programming. Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 23, 2018 Share Posted January 23, 2018 The transcode settings don't apply to recording TV. What HDHomerun are you using? Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted January 23, 2018 Author Share Posted January 23, 2018 Hello, The model is HDHR4-2US Link to comment Share on other sites More sharing options...
Guest asrequested Posted January 23, 2018 Share Posted January 23, 2018 Ok, I was wondering if you had one that has hardware transcoding. I don't think that model, does. Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted February 2, 2018 Author Share Posted February 2, 2018 Hello, I'm just checking to see if this issue will be addressed in the next update so that I may activate the feature to "Automatically convert recordings to a streaming friendly format".

UnderMiner 11 Posted March 1, 2018 Author Share Posted March 1, 2018 (edited) Hello, I updated to the latest version of Emby Server after waiting for over one month and hoping that this issue would be fixed but unfortunately, the behavior is the same. When I turn on the transcode feature, we cannot playback in Emby Theater both in Windows and on Xbox. It works in the Firefox browser. I updated the log files in the location shared in the first post. Please review and let me know if the issues with transcoding may be fixed. We need this feature to improve skipping speed and to reduce hard drive space. Thanks. Edited March 1, 2018 by UnderMiner Link to comment Share on other sites More sharing options...
UnderMiner 11 Posted March 2, 2018 Author Share Posted March 2, 2018 Hello, I included the link to the Feb 28 server logs to hopefully have some feedback to assist with this issue. I removed the transcoding feature for the moment but this make Emby difficult to use because it uses a lot of disk space and all of the server CPU. https://1drv.ms/f/s!AnfmLnbQksWOhytOE0vZjYY-aJvZ Link to comment Share on other sites More sharing options...
