Media playback hangs on recently added library files

[bradgy 0]

Haven't been able to figure out why some of my recently added tv files are getting to the fanart wallpaper stage when trying to stream but then hanging and not reaching the video OSD stage. It's been happening with a range of shows over the last 2-3 weeks. It's affecting all users on the server despite the client platform (firefox, chrome, android). Items in the library added before this 2-3 week period still play perfectly.

 

Additionally, I've noticed that the details of the affected files don't show up on the episode page, whereas they do for the episodes that play normally. Screenshots to illustrate:

 

 

 

So, I'm not sure whether it's a library problem, a streaming problem, or something else. I've attached the logs from immediately after playing one of the affected episodes. Hoping they can shed some light on the situation.

 

Thanks for any assistance in advance.

What is the H264 level for both videos? The last line caught my eye. Take a look at the level:

2017-03-20 11:55:25.1168 Info HttpServer: HTTP GET http://209.6.46.247:8085/emby/videos/13654d2007fe50f7f90787dec981cb3f/live.m3u8?DeviceId=939af463011cd666c60b3f338a2564f9&MediaSourceId=13654d2007fe50f7f90787dec981cb3f&VideoCodec=h264&AudioCodec=aac&VideoBitrate=1808000&AudioBitrate=192000&Level=51&Profile=high&PlaySessionId=39fb30a931ff43bab47993072b9a24d4&CopyTimestamps=false&TranscodingMaxAudioChannels=6&EnableSubtitlesInManifest=false&Tag=dc66f2dd87cc2a8dce1cf3c2ad827af7&RequireAvc=true.

The newest beta adds support in more browsers for level 51 H264. Check out the release notes.

 

It's just a guess. Perhaps someone with a more discerning eye can offer something more than a guess

Did you take a look at the last line of your ffmpeg log as well?

file:/mnt/af5fd582-ddca-4b22-805a-3c9f92175a66/Newest TV/The Walking Dead/Season 7/The Walking Dead - 7x13 - Bury Me Here.mkv: Permission denied

What user is Emby running under and how did you mount that filesystem? I've seen it where I had to manually change the mount point permissions after the fact because I didn't mount it properly.

 

Maybe the details aren't showing up because it isn't able to write a file somewhere or save temporary transcoding data?

Yes it looks like ffmpeg cannot access that location.

Oh, well spotted! I completely missed that line, as obvious as it seems now. Emby is running under its own user 'emby'. Looks like it could be a permissions issue, I'll check the mount and file/folder settings and report back.

Thanks for the update.

Problem appears to be resolved.

I changed the permissions for incoming library items so that user 'emby' would be able to read them, and it looks like I might have been ignoring a fairly crucial warning in my nzb downloader that was leading to the creation of some weird files (it wanted python-sabyenc for anyone that's wondering).

 

Thanks for the quick support Emby community.

Thanks for the info !
