Conversion failures to SMB share

[Pippinuk 5]

Hello All

I was seriously hoping a conversion issue would be resolved with the recent update but unfortunately I still see issues when converting media. The conversion happens and a file is written to the fileshare but it is 0kb and the conversion stays as 'ready to transfer' in the queue. One of the conversions I attempted has overwritten the original file with 0kb file and so I lost the media altogether. I am writing to an smb share on a NAS. 

Here's some log entries that may help and thank you for any assistance!! And I have attached the full embyserver log file

Add embyserver log file

So you are selecting the option to overwrite the original file when converting?

Suggest you change that whilst the issue is being investigated

I will see if I can replicate the problem

Based on the log I guess it timed out:

That is a quick timeout though, so I guess the question is what layer threw that timeout.

Thanks so much for your responses! I really appreciate it. I should have tested the 'next to original file' - I'll do that later and let you know what happens

@PippinukI have tested both options on 4.9.1.80 on a ubuntu machine with smb to windows PC and they both worked. It was on a small .ts file (110Mb)

Test to convert placing output adjacent to original file

Thanks for doing that!! That's awesome. Ok, it has to be something my end. I'm gonna have a dig into tonight and see what I can find. I'll let you know and thanks again man!

[sa2000 674]

you could look into packet capture and filtering smb2 and dig into that - not easy to debug smb dialogue

i captured all communication using wireshark on the windows machine

i will run a test with a massive file !

Should these back slashes be forward slashes?

Check how your smb mapping is configured but I almost bet you need the 'nobrl' option

Hello All!! I am so sorry it's taken so long for me to reply. I've changed my setup to mount the SMB share to the local Linux host, then mapped that mount point to Emby via docker compose. Since then, all is well  
Without wanting to sound like a D, the conversion seemed to lose tooich quality so I think I'm looking at handbrake or similar to retain quality whilst converting to common formats. Either way, Emby is awesome. I love it. X

Thanks for following up.
