Transcoding of http live stream mkv file does not work

[mikojacko 0]

Hi to all,

i'm trying  to use Emby to transcode some mkv video sources to my home devices (TV, smartphone etc)

 

I have some http links of some video-on-demand contents that perfecty works with VLC Kodi and so on....

 

I've created a folder with .strm files for each content 

          titanic.strm   

 

this file contain the link of the content 

      http://xxxxxxxxxxxxx:8080/xxxxx/xxxxxxxxxx/xxxxxxxxx/372.mkv

 

So i've added the folder to emby library (for scraping andi indexing) and then tryed to stream the content via emby.

The stream does not starts nor using webclient nor ios client nor every clinet i've tested.

I've seen than emby, try to transcode the stream but the transconding logs seem to "hang"

 

https://paste2.org/wfC4w5zw   transconding.log

https://paste2.org/m5CCjGGn  server.log

 

the strange thing is that, if in the meanwhile i run the same fmpeg.exe command (taken from le transconfing.log file ) from the command line (by myself) the transocoding starts, the temp files is generated and the streaming starts!

 

1. 
   
   C:\Users\BeLab\Desktop\ffmpeg-3.1.4-win64-static\bin\ffmpeg.exe -fflags +genpts -i "http://xxxxxxxxxxxxx:8080/xxxxx/xxxxxxxxxx/xxxxxxxxx/372.mkv

Hi Luke,

I've restarted the server and logged anything

 

My action:

-restart server

-connect via iphone clinet to emby

-request a video

-emby server starts the transconding task (the trasncodingxxxx.log is created)

-i've selected the ffmpeg command taken from transcondigxxxx.log ed execuded manyally via cmd

-the video stream started with no problem.

 

Without my manual intervention the trasconding does not starts

Hi, please try using this version of ffmpeg:

https://github.com/MediaBrowser/Emby.Resources/tree/master/ffmpeg/windows

 

You can download, then customize it in the Emby Server dashboard under Transcoding. Let us know if this helps. Thanks.

So, i've tried to download the same mp4 file (that via http stream does not works)  and point the strm to the local file. In this case emby works (the transconde works fine )

it seems there is a bug in ffmpeg while retrive the stream via http.

Still i don't understand why if i execute the same command via cli manually everything works.

So it's just stalling on that URL for some reason. Thanks for the report.

[mikojacko 0]

So no clue or suggestion? How can I report this bug  ?

I think is not ffmpeg problem (via command line it works)

Please try this again with the next release of emby server. Thanks.
